572 APPENDIX. 
factorily to any in E. B,, and I therefore send them, though I have no idea but 
that they are well known to you. : 
“My friend Mr. Watson informs me that you are writing a Monograph of 
Staphylini, which Iam extremely glad to hear, as my little experience hag 
convinced me that there are many English ones yet undescribed ; and, ina 
genus where so many species are of the same colour, long and full descriptions 
are peculiarly requisite. All the unnamed specimens I had of this genus I 
sent to Mr. Marsham; and if he finds any likely to be new to you, he will 
doubtless send them to you. I herewith enclose a few specimens. I shall be 
glad if any of them are new to you: if not, you will oblige me by returning 
them, named, by Mr. Rodwell, for my information. 
“No. 13. I have called S. obscurus. It is common on the shore of the 
Humber. 
“No, 14. must be S. eruentatus, not uncommon here. I send these two, be- 
cause of their having local habitats given them in E. B. 
“No, 17. is not uncommon here, but I can find no one in B, B. with which 
it accords well. The remaining Staphylini, chiefly minute ones, I have not 
particularly examined, and probably many of them are described in E, B. 
“No, 18, is a Cassida which I took some months ago, but I forget where. I 
am doubtful if it be. described in E. B. With the specific character of C. si- 
milis it perfectly accords, but not with the size or the description, for ncither is 
the thorax longitudinally elevated, nor are the feet pallid,—the thighs, except 
the apex, being wholly black. Can it be your C, liriophora? yet I see nothing 
of the macula and black puncta youmention. This I shall be able to determine 
shortly as I have at present by me two or three of the pups of, I expect, your 
C. liriophora, which I have found and fed, as you direct, on Carduus arvensis. 
“ Searites thoracicus of “ Iliger’s ‘ Kiifer Preussens,’ I have found abundantly 
in the dried-up mouth of a pond, along with Heterocerus marginatus. Mr. 
Marsham tells me he has had it sent him, perhaps by yourself, I send, how- 
ever, one or two specimens. 
As Mr, Marsham mentions the place where, and person by whom, Cocci- 
nella 18-guttata was taken, I presume it is not found by every entomologist 
everywhere, and I therefore send a specimen. Its habitat is Pinus sylvestris, 
from different trees of which I shook, the other day, five or six specimens, 
“This ends my list of duplicates of insects in my possession that there is a 
possibility of being new to you. I am sorry it is not in my power to send a 
greater number, 
“Since I began my entomological career, which is within these six months, I 
have stumbled on a few insects to a certainty not described in EB. B., viz. 
Donacia appendiculata and Carabus spinilabris of Panzer, ‘aun. Germ.,’ and 
Carabus dorsalis and C. discus of Fabricius, ‘Ent. Syst.’ Of these I have not 
duplicates, and I have sent them to Mr. Marsham. Since I wrote to him, I 
have found four or five specimens of Carabus clevatus of Fab. ‘ Ent. Syst.’ No. 
166. (not 33., which very absurdly has the same trivial name). One of these, 
No. 20., I enclose. Whether these have been found by any one else since the 
pu unlos of I, B,, I am ignorant.— But I hasten to conclude this long 
etter. 
“T am, sir, respectfully, 
“ Your most obedient servant, 
“Winriam SPENCE.” 
To this letter I had the pleasure of receiving the following reply from 
Mr. Kirby :—
