APPENDIX. 577 



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 distinct genus, intermediate between Byrrhus and Cistela. I also found 

 a nigro-ffineous 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 Spharidium humcrale, Fabr. 'Ent. Syst.' i. 79. 9. You re- 

 member my taking a small ferrugineous Nitidula upon the new pales as we 

 went to the pit ; it turned out Sphceridium 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 sahulosus, 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 *l 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. 



" I am going, if stout enough, — for I have been much troubled since you 

 left Barham, with lumbago, — 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. I take 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 via, but I must go solus 

 cum solo Hangero.* Poor Sheppard can't foot it so far, and there is no other 

 keros entomolocficus in this neighbourhood. I wrote to Mr. MacLeay, but he 

 can't get out for even a single day, he says. I had 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 soon 

 return. I have been extremely busy upon the natural characters of Staphy- 

 linus, and have made drawings of the antennce, palpi, &c., of several of my 

 families. I have not yet determined whether it is to be CaUicerus Spencii 

 or Aleochara Spencii, the palpi come so very near the latter genus. I often 

 wish for you at my elbow to give me a lift, when occasionally I feel my- 

 self stupid. I find it difiicult to get a clear idea of the interior palpi of 

 Stenus. In this drawing, a, is the end of the tongue, and, b, 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." 



"Barham, Sept. 24, 1806. 

 " Dear Sir, — I was gratified to find your tour was so pleasant and suc- 

 cessful. Mine, unfortunately, terminated difiercntly, and my entomological 

 captures (of consequence) did not reach a Greek plural, being in number only
