Cole^ptera from (he Indian Empire. 425 



small Indian Onlhophagi of wliich 0. vidcanus, Fab., is the 

 type. It is most nearly related to Caccobius tortus, Sharp, but 

 is more closely sculptured, especially upon the prothorax, and 

 the elytra are witiiout the yellow apical spot distinguishing 

 that s]>ecies and O. vulcanus. It is jjcculiai' also in having 

 the middle of the prothorax angularly instead of broadly 

 prominent in the male. It has been found in numbers by 

 Mr. H. L. Andrewes in the Ouchterlony Valley, Nilgiiis 

 (3000 ft.), in April and July. 



Another species of the same group, although not hitherto 

 associated with it, is 0. furculus, Fab., in which the elytra 

 are maiked with yellow in front and behind, and the mai-gin 

 of the thoracic excavation is not sharply raise J. Tliis is 

 found in the same localities and also in Ceylon.
