May 3rd. 1846

Dear Sir

Those in your list which I am in want of are the following

Calathus piceus. --

Agonum piceum -- The Agonums puzzle me much & I shall be glad of any specimens you have to compare with mine --

Peryphus cuemeryshrus.

Apion virens

A. humile

Colymbetes sturmii

Cryptophagus ulicis.

Aphodius sphacelatus -- I think I have this, but am not sure of the species --

Oulhophagus ovatus

O. coenobita -- I am not sure of this species

Harpalus rubripes

Silpha loerigata



I find while I have so many of the larger species to date I cannot pay the necessary attention to the more difficult smaller ones such as the minute Brachyelytra & Neerophaga -- The following are what [[2]] I have taken from my last list up to the present time --

xLeistus spinibarbis rather plentiful in woods

L. fulvibarbis! 2 will do

L. rufescens -- 1 under stone

Chloenius vestitus -- 2 banks of River Neath

√ Amara tibialis ?. on Crynilu Burrows

√ A. erythropa ? -- do --

√ Trechus fulous.

√ T. suturalis.

Tachypus properans.

T. celer

Tachys binotatus -- in grass.

Ocys melanocephalus? bank of

Tempestivus.!!. } on fallen tree

Hydroporus 12-pustulatus. Neath Canal

H. pygmaeus?-- -- do.

H. tristis --

H. palustris. --

*Hygrotus pictus -- --

" scitulis --

" inequalis --

Haliplus fulvicollis.

√Noterus semipunctatus

Laccobius minutus. --

*Necrophorus vespillo -- in dead crow

*N. humator. -- do

[[3]] Catops festinans

xTrichoderma pubescens. Abundant

Trichoderma nebulosum. 2 in carcasses.

xStaphylinus erythropterus -- not uncommon.

Hister cadaverinus -- will do

xCreophilus maxillosus -- plentiful i[n] dead horse.

Meligethes coeruleus -- flowers.

√xOnthophagus Deliogria -- plentiful.

" fracticornis ? --

√xTyphoeus vulgaris. -- under cow dung under thickets -- in holes not near so deep as Geotrupes stercorarius.

Agrypnus murinus.

xHypolithus riparins -- not uncommon

x√Apions frumentarium.

A. nolaceum

A. apricans

Leiophleus nubilus -- on nettles fine.

Alophus 3 guttatus -- do do

Hypera [1 word illeg.]

√Otiorynchus scabrosus?

Polydrusus calcaratus.

Phyllobius argentatus.

√xHydrononius alismatis -- on aquatic plants.

Haltica brassicoe.

√x H. pseudacori. on Iris pseudacorus abundant.

with [1 word illeg.] small specim[ens] [1 word illeg.] not yet named.

[[4]] We have one of Mr. Dilwyns Catalogues of the Swansea Coleoptera at our library here -- There are a great many nice species in it -- And I have no doubt I shall get several of them this summer. Cicindela maritime & Nebria complanata I dare say I shall get in June. I have sent you a tracing of a map to shew you the situation of the Crynilin Burrows &c... The Burrows is merely a tract of nearly level sandy ground generally covered with short grass & such plants as "erodium cicutarium" "Erophila vulgaris" "arenarius" &c... The low parts subject to inundation from the sea are covered with the great sea rush "juncus mantimus" -- [[5]] the "Salix argenta" & gorse and -- the heaps of sand blown up immediately adjacent to beach Elymus arenaria, and Euphorbia paralias and other sea shore plants -- The [1 word illeg.] next Swansea is most flat that next Neath River is broken by several pieces of rock using perhaps 200 feet partly covered with woods & the sand heaped about then forms a little range of hills -- I think I have forgot in my list Aegialia gorbosa which is very abundant attempting to crawl up the bar hills of blown sand most perseveringly -- Crynilin bog produces many rare bog plants & marsh insects but from the quantity of water it is [[6]] very different to get into it. The Neath & Swansea valleys are formed by Rocky mountains mostly covered with oak woods on their sides and poor mountain farms on their summits & upper slopes -- The Rock is the sandstone of the coal formation -- Along the sides of the River Neath for about 3 miles up from its mouth are flat marshy lands overflowed at spring tides -- In the lower part of the valley is a deposit of dialluvial gravel on each side forming some good undulatory land -- The section of this part would be thus [a sketch of the terrain appears here] [[7]] High up the valley the dialluvial is wanting -- On the sketch the dark colour shews[sic] the woods and plantations. The mountains[?] rise about 1000 to 1500 feet but in the upper part of vale to 2000 & at its upper extremity abt 15 miles from Neath to upwards of 2500 feet. The upper part is crossed by the mountain limestone, and a district 4-5 miles wide separating the coal basin from the O. Red sandstone is highly Romantic & beautiful -- The mountain limestone also appears to the W. of Swansea as I have shewn by cross lines -- which district I intend if possible taking a few days tour through & expect to get some novel species.

[[8]] I got some Ent. pins some time since & use them for all of my Coleoptera except the very large ones & the small or tender ones.

I have an eye glass with 3 lenses which I use either singly or combined but in the latter state it wants distinctness & light -- How should a ¼ inch lens be mounted? as a common eye glass or as a entomological microscope? --

I have seen some mounted at the top of a little glass cylinder which you put down over the object & then adjust with a screw -- Just before receiving your last I had discovered what I thought was a cassida to be Thymalus limbatus[.] It is rather rare here.

I must now remain | Your sincerely | Alfred R. Wallace [signature]

Mr H. Bates
