60 COLEOPTERA. 



decidedly B, glahratua^—hdiYing unspotted antennap, and 

 more roughened elytra than in Dr. Power's insect, and 

 otherwise presenting considerable points of diflPerence. 



Another of Mr. Murton's specimens, sent to me by Mr. 

 Sidebotham, differs widely from both of the above-men- 

 tioned examples (though supposed to have been taken in their 

 company), being larger than either of them ; with unspotted 

 antennse, and, as compared with explodens, more elongate 

 front to the head, and longer elytra, — which are, moreover, 

 not nearly so sm.ooth, and have more prominent shoulders, 

 with a lurid red stain below the scutellum. This insect 

 exhibits a superficial resemblance to B. sclopeta, for the 

 reason last above mentioned; and, indeed, is the specimen 

 on which were founded the rumours (mentioned in the last 

 " Annual ") of that species being taken : it differs, however, 

 from B. sclopeta in being much larger, with more elongate, 

 less convex, and rather duller elytra ; and in having the 

 underside, &c., of the same colour as the same parts in 

 cre])itan$, instead of the bright clear red so peculiar to the 

 former species. The stain on the elytra, also, appears to be 

 accidental ; as it is not equilateral, nor sufficiently con- 

 tinuous with the scutellum, which is rather dark. It is 

 very curious that these three specimens should be all dif- 

 ferent. I believe no more have been taken since their cap- 

 ture ; but it is to be hoped that the district in which such 

 puzzles occur will be well worked.

 Mr. J. F. Dawson has sent me his unique example of 

 this insect ; which, apart from its extremely dai-k colour, 

 differs from any S. dorsalis that I have seen (although I 

 possess one of the Wimbledon varieties of that species,
