Olive-green ; the face ochre-yellow; wings infuscated, with a black spot 

 upon the last segment of the fourth longitudinal vein ; fore coxae red- 

 dish-brown ; feet brownish-red. 



£ . Middle tibiae very stout, crooked, on the upper side with small black 

 spines; the middle tarsi entirely black; their first joint thickened, 

 curved upwards, on the upper side with black bristles ; fore and hind 

 tarsi plain, from the tip of the first joint black. 



5> . All the feet plain ; all the tarsi from the tip of the first joint, black. 

 Long. corp. 0.09. Long, ah 0.14. 



Olive-green ; thorax more bright than the abdomen, near its 

 fore margin with a few strikingly green reflections. Front black- 

 ish-blue. Antennas entirely black ; the third joint small and not 

 pointed. Face brownish ochre-yellow. Palpi ochre-brownish. 

 Proboscis black. Cilia of the posterior orbit black above, below 

 pale. Fore coxae brownish-red, sometimes yellowish-red, with a 

 white reflection near the root and a large part of the outside 

 brown ; the four posterior coxae grayish-black, the trochanters 

 brownish-black. Feet yellowish-red ; the knees, especially those 

 of the hind feet, more or less infuscated ; all the femora, the fore 

 and hind tibiae, as also the fore and hind tarsi are plain in both 

 sexes, the latter blackened from the tip of the first joint. The 

 middle tibiae and middle tarsi are only in the female of the same 

 plain structure and of the same color, while they are distinguished 

 in the male by a very different structure ; for its middle tibiae are 

 uncommonly stout and somewhat curved ; the greatest thickness is 

 in their middle ; the last two thirds of the posterior side are excised 

 and provided with a brown stripe ; before this excision, almost on 

 the upper side of the tibia, there is a longitudinal row of black spine- 

 like bristles, which does not occupy, however, the basal third and 

 the apical one-fourth of the tibia ; the second half of the tibia 

 bears upon the other two sides a few long black bristles ; the 

 middle tarsi of the male are entirely black ; their first joint is 

 somewhat curved upwards at the tip, stout and near the extreme 

 basis a little more swollen, on the upper side excised furrow-like 

 and fringed with a row of black bristles ; the following joints are 

 plain, the second not quite so long as the third, and at the extreme 

 basis sometimes of a yellowish-brown color. Wings with a dis- 

 tinct smoky black tinge and with a small blackish spot upon the 

 last segment of the fourth longitudinal vein.
