VARIETIES. 515 



may state, that the Captain sent them to me for names, and 

 I beg to make a few corrections. Polia bicaitdata should be 

 Perla bicaadata; Ceria conojjsoides should be Doros co- 

 nopseus; Bombus Harrisellus should be B. subterraneus ,- 

 Osmia maritima should be Megachile maritima ; Andreiia 

 aurata should be A. armata ; Tabanus viltatus is in Curtis's 

 Guide, G. 1185, Sp. 5. The remainder I cannot at present 

 explain. J. C. Dale. 



48. Acanthosoma incta, (Vid. ante, p. 287.) — I saw this 

 insect, with the same name attached, in the Linngean cabinet. 

 I took four or five in Middleton Park, near Oxford, on the 

 juniper-bushes ; and Mr. Matthews has taken them through 

 last winter in great abundance at the same place.

49. Genus Charissa. — I have taken C. serotinaria on a 

 chalk soil, as in the Isle of Wight, for instance, and always 

 whitish; C Pidlaria, on stony chalk, at Dover, is rather 

 darker; and another variety, on Portland stone, darker still; 

 besides a variety at Monk's Wood, which appears inter- 

 mediate. I have taken C. dilucidaria at Teignmouth, 

 between grass and heath ; and one, very nearly allied, on the 

 Mendip Hills, out of furze and on old walls. C. obscuroria, 

 which I have taken on Parley Heath, is very dark indeed. 

 Is it not possible that all these are but one species ?

50. Genus Carabus. — I first detected C. cancellatus as 

 being distinct as British, in Mr. Ingpen's cabinet, where it 

 was ticketed C monilis, and had been overlooked by several 

 entomologists for some time previously. C. auratus is stated 

 to have been found at Exmouth. On looking at the cabinet of 

 insects in the British Museum, I find a specimen of this insect 

 ticketed thus, " Ex Mas. D. Pitt qui legit prope Exeier" 

 Mr. Wailes has also a specimen, found by a gentleman near 

 Canterbury, and conveyed home in a snuff-box.
