Several examples of this species were captured, exhibiting almost 

 every gradation in size within the limits of the measurements given 

 above. 



The species is closely allied to Examnes pJiilippensis, IS'ewm., 

 from which it diifcrs chiefly in having the prothorax broader, more 

 rounded at the sides, and marked above with four distinct tawny- 

 coloured pubescent spots, placed two on each side, one near the 

 base, the other close to the apex. 



In the Munich Catalogue, JExamnes pkilip])ensis, Newm., is 

 placed as a synonym of Ceresium simplex, Gyll. It is, however, 

 quite distinct from that species, and appears to me to be identical 

 Avith Exmimes longicornis, Pasc, a species which, in its turn, is not 

 to be distinguished from Examnes idoneus, Pasc.
