Long. 9-20, lat. 2*5-5*5mm. 



Several examples of this species were ca^Dtured, exhibiting almost 

 every gradation in size within the limits of the measurements given 

 above. 



The species is closely allied to JExamnes philippensis^ JS'ewm., 

 from which it differs 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, Examnes pliilipioensis, Newm., ia 

 placed as a synonym of Ceresium simplex, Gi-yll. It is, however, 

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

 with Examnes lo7igicornis, Pasc, a species which, in its turn, is not 

 to be distinguished from Examples idoneus^ Pasc.
