anterior and middle pairs, are mucli stouter than in the present 

 species ; and the antennae are only a little longer than the body,, 

 with the eleventh joint distinctly shorter than the tenth.

Brunneo-testaceus, setis albo-fulvescentibus sat dense obtectus ; 

 abdomine piceo-nigro ; scutello, capitis fronte verticeque et pro- 

 thoracis maculis quatuor f ulvo - pubescentibus, prothorace quant 

 longiore pauUo latiore, fortiter sub-rugosoque punctato ; elytris 

 sat dense punctatis, punctis setigeris et versus apicem gradatim 

 decrescentibus ; antennis (J') quam corporc duplo longioribus, 

 (9) quam corpore baud sesqui-longioribus. 



Long. 9-20, lat. 2-5-o-omm. 



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 philippensis, Newm., 

 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 fliilippensis, 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 

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

 to be distinguished from Examnes idoneus, Pasc.

 fi'om China to North Australia), but differing from it by the following:
