Cryptopleurum atomarium, Fab. var. ? A single 

 specimen of a Crj/ptopleurum, sent to me by Mr. Lewis, 

 appears to differ from our Eiu'opean C atomarium by the 

 finer sculpture and more distinct pubescence of its upper 

 surface. Whether it be a distinct species or not I cannot 

 yet decide. A specimen of C. atomarium from Amurland, 

 in my collection, does not appear to differ from our 

 Scotch specimens. 



Megnsternum cjibhulum, Mots. A number of specimens 

 of a small Meg a sternum appear on their upper surface to 

 differ from M. holeiopliagum only by their more coarsely 

 and closely punctured head and thorax. Motschoulsky's 

 sliort diagnosis of M. gibbulum from Japan indicates that 

 species as differing from M. holetophagiim only by its 

 broader form. Though the specimens before me do not 

 seem to me to be broader than ordinary specimens of 

 M. holeiopliagum, there can be little doubt, I should 

 think, that they must belong to the species intended by 

 Motschoulsky, as it is not at all probable that there 

 should exist in Japan two species so closely allied to 

 JSI. bolctophagnm. The species from Japan, though so 

 closely resembling the European M. boletophagum, is cer- 

 tainly distinct therefrom, for whereas in JM. boletophagum 

 the first abdominal segment is closely and distinctly 

 punctured, and the others are shining and impunctate, in 

 the Japan species, on the other hand, all the segments are 

 very distinctly punctured. The prosternal plate also 

 differs much in the two species ; in M. boletophagum its 

 centre is elevated, Avhereas it is not so in the species from 

 Japan.
