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 I am extremely glad to hear, as my little experience has 

 convinced me that there are many English ones yet undescribed ; and, in a 

 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 liicely 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. Kodwell, for my information. 



" No. 13. I have called S. obscurus. It is common on the shore of the 

 Humber. 



" No. 14. must be S. cruentatus, 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 E. 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. 1 8. 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 neither 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 you mention. This I shall be able to determine 

 shortly as I have at present by me two or three of the pupae of, I expect, your 

 C. liriophora, which I have found and fed, as you direct, on Carduus arvensis. 



" Scarites thoracicus of "lUiger's ' Kafer Preussens,' I have found abundantly 

 in the dried-up mouth of a pond, along with Heterocerus marginatus. Mr. 

 Mai'sham 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 \S-guttata was taken, I presume it is not found by every entomologist 

 everywhere, and I therefore send a specimen. Its habitat is Pimis sylvestris, 

 from diflferent 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 E. B., viz. 

 Donacia appendiculata and Carabus spinilabris of Panzer, ' Faun. 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 elevatus 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 

 publication of E. B., I am ignorant. — But I hasten to conclude this long 

 letter. 



"I am, sir, respectfully, 



" Your most obedient servant, 



" William Spence." 



To this letter I had the pleasure of receiving the following reply from
