Genus nelomicriis Costa 



The group of species referred to this genus are alike in having the punctura- 

 tion of body fine, close, and remarkably uniform. They all have on the anterior 

 two-fifths of mesonotum a very fine double median stria. The scutellum is always 

 entirely without a median carina. The squamae are quite characteristic, not pos- 

 sessing either a lateral or a terminal tooth, and completely enclosing the post- 

 scutellum. The sculpturing of the metanotum is peculiar to the group ; there are 

 median and lateral carinae, the lateral being distinctly elevated above ; the median 

 fovea is of various shapes ; the lateral faces are covered with numerous fine irreg- 

 ular oblique striae, and between these the surface is variously punctuate. The 

 clypeus is usually stated to be simple in both sexes, but in the male of cookii it is 

 tridentate. The lateral ocelli are said, in generic characterizations, to be as near 

 to the median ocellus as to the eye margin or nearer, but in colorata for instance, 

 they are nearer to the eye margin. A sharp groove extends from the upper part 

 of the inner eye orbit to the lateral ocelli.
