116 COLEOPTERA. 



Cercyon centromaculatum, Stephens. 

 Mr. Crotch (loc. cit.) also sinks nigrice'ps of Marshara ; 

 stating that his description agrees with a pale var. of pyg- 

 mceum, there being no allusion to the central shade. 



Megasternum boletophagum, Er. 

 Mr. Crotch (loc. cit.), after stating that Marsham's descrip- 

 tion and name certainly apply well to this species, and, 

 whatever his type may be, his diagnosis was never drawn up 

 from O. minutum, says hence he sees no reason to substitute 

 the less expressive name of C. obscurum (which is Marsham's 

 name). Surely Mr. Crotch intends to read heie " boleto- 

 phagum ",• but he retains that name in his Catalogue. 



Melanotus punctolineatus, Pelerin, Zool. Journal. 

 nigevj Fab. 

 Mr. Crotch (loc. cit.) proposes to adopt Mr. Pelerin's 

 name, if niger be retained for the Ath'dus. 



CrYPTOHYPNUS QUADRIGUT^l^ATUS, Lap. 



Mr. Crotch (Ent. 32, p. 124) states this to be commoner 

 here than C. dermestoideSf which has immaculate elytra and 

 dark base to the antennae. He appears doubtful whether the 

 two are specifically distinct ; I can only say that I have taken 

 insects showing these colour differences indiscriminately to- 

 gether, and with connecting gradations. 



Cardiophorus thoracicus. Fab. 

 Although the author of this species described it from a 

 British example, Mr. Crotch (loc. cit.) seems doubtful of its 

 real claim to be indigenous ; the apparent reason being a mis- 

 take in Mr. Wollaston's collection.
