G. unicoloiv 



Resembles a Dicranomyia in figure : the cylindrical rostrum is 

 longer than the head ; the palpi are inserted under its lateral 

 margins, consisting of one minute ovate-conic joint : the tongue 

 and lip are elongated into a rigid slender proboscis, twice as long 

 as the rostrum : the lip terminates in two slender flattened lobes 

 applied to each other, and containing between them the tongue, as 

 fine as a bristle, and admitting of being pushed out a little. (The 

 •whole apparatus has a very blood-sucking appearance.) The eyes 

 are separate on the upper side of the head : the thorax is glossy 

 brown, immaculate, with very deep sutures : the incisures of the 

 abdomen darker, borer reddish : poisers, legs, and proboscis, pale 

 yellowish : antennae and rostrum dusky : wings bluish : the 

 nervures finely pubescent, disposed as in D. chorea : subcostal 

 pale yellow, with two short dusky lines, placed as those included 

 in the costal spots of D. oscillans. (Length from tip of proboscis, 

 .32 ; expans. .66.)
