36. Obrium posticum, sp. n. Falvu-testaceum; capitis fronte, pe- 

 dibus (dimidiis basalihus femorum exceplis), elytrorumque apicibus 

 piceo-tiigris; anleiinis arliculis 4 basalihus nigris, ceteris obscure 

 fulvis. Long. 9 mm. 



Mandalay. One example. This species has the general appea- 

 rance of Obrium canlharinum, Linn. It is of about the same 

 size ; and the punctuation is very similar in the two species. 

 It may be distinguished by the black front of the head, the 

 black apex of the elytra and the black legs. The prothorax ap- 

 pears slightly broader, in proportion to the size of the insect, 

 than in 0. cantha.rinum,; and the tubercle on the posterior median 

 part of the disk is almost qaite obsolete.
