217 



rather shining, and strongly punctured, 2nd joint of the flagelluni 

 longer than the 4th, 3rd shorter than the 4th, mesonotuni finely 

 rugulose and with a fine remote, but distinct puncturation ; propodeal 

 area well defined, finely and somewhat clathrately rugose, its 

 surroundings finely rugulose ; al)domen shining, its rugulosities 



more superficial than in most of the forms, impressions well marked, 

 sculptured much as the rest of the segment, slightly discoloured at 

 the apex, armature very peculiar in the strongly incurved and nairow 

 stipites ; apparently a very distinct species, but in neither collection 

 can I find any $ which looks likely to belong to it.
