Pselaphus like Anthicus Dresdensis (Panz, 98, i.), but with a narrower thorax, 
and palpi equally remarkable, and a very minute Cistela, nearly related to 
Cistela maritima, E. B., but much more diminutive, with the same characters 
exactly, except that the feet are red. This, with maritima, seem properly to 
form a distinet genus, intermediate between Byrrhus and Cistela. I also found 
a nigro-sneous Omalium (once Acidota), of which I had never taken but one 
before in the same spot. The last time I took only a black Anisotoma, which I 
had taken there once before ; nothing else of consequence has found its way 
into my phials. Sheppard’s Tetratoma that he finds upon the fir, of which he 
gave you a pair, is Spheridium humerale, Fabr. ‘ Ent. Syst.’ i. 79. 9. You re- 
member my taking a small ferrugineous WVitidula upon the new pales as we 
went to the pit; it turned out Spheridium Colon of Panzer, 84,i., but certainly 
not of Fabricius. Sheppard writes me word he has taken two more of Apion 
nigritarse upon Corylus, and above thirty Trox sabulosus, under the old ram’s 
horn, where I took three, One of the Staphylini which you took at Levington 
you left here: it proved to be Staph. cephalotes of Gravenhorst, and looking at 
my MS,., I find I had referred to your cabinet for it: therefore, concluding you 
had a specimen, I put it in my own cabinet; if you find I am wrong, tell me, 
and I will send it with the rest. The Apion you found upon Lathyrus pratensis 
proves to be my Apion sabulatum; that upon Ononis, a variety of my Ervi. I 
found a nondescript one among Mr. Hooker’s parcel, which I have called 
rotundicolle, from its globose thorax. ‘There were forty insects in the two 
boxes [Mr. Hooker's] that were either new or very rare, 
“T am going, if stout enough, — for I have been much troubled since you 
left Barham, with lambago, — on Monday next, to take the tour of the Suffolk 
coast on foot, from Walton, where we slept, to Yarmouth, and hope I shall 
make some additions to the catalogue of British insects, and to the collections 
of myself and friends. Itake a fortnight for the purpose ; shall go to Sheppard’s 
on Sunday evening, and then proceed leisurely, and return home, I believe, 
inland. If the weather continues as fair as it is now, the expedition will be 
delightful, and I shall only wish you were my comes in vid, but I must go solus 
cum solo Rangero.* Poor Sheppard can’t foot it so far, and there is no other 
hervs entomologicus in this neighbourhood, I wrote to Mr. MacLeay, but he 
can’t get out for even a single day, he says. Thad a letter from our good friend 
Marsham not long since ; he has been to visit the Dean of Rochester and Mr.. 
Lambert (at least he was going when he wrote), but, I suppose, will soom 
return, I have been extremely busy upon the natural characters of Staphy- 
linus, and have made drawings of the antenne, palpi, &c., of several of my 
families. I have not yet determined whether it is to be Callicerus Spencit 
or Aleochara Spencii, the palpi come so very near the latter genus. I oftem 
wish for you at my elbow to give me a lift, when occasionally I feel my- 
self stupid. I find it difficult to get a clear idea of the interior palpi of 
Stenus. In this drawing, a, is the end of the tongue, and, 4, the interior 
palpi as they appear from a specimen of mine. I think they are biarticulate, 
but cannot satisfy myself on this point. Be so good as to examine one of 
yours, and give me your ideas. When you go to Ripon I shall be glad to 
hear of your success, and shall detail to you the result of my expedition, 
“ Believe me, &c.”

“ Dear Sir, —I was gratified to find your tour was so pleasant and suc- 
cessful, Mine, unfortunately, terminated differently, and my entomological 
captures (of consequence) did not reach a Greek plural, being in number only
