and black parts visible. A few moderately long bristles at 

 the end of sixth, as of the other segments. Front coxae green at 

 base, changing through brown to yellow at the tip, considerably 

 white pollinose. A row of black bristles at the tip, and a few 

 fine yellowish hairs on the front side. Middle and hind coxae 

 blackish, the former has a number of stout bristles on the fore side, 

 one near the base is more lateral and quite prominent. Hind coxae 

 with a single lateral bristle. Trochanters all yellow. Femora 

 all dark-green, somewhat shining ; the front and middle ones 

 broadly, the hind ones slightly, yellow at the knee. Tibiae all 

 yellow, the hind ones a little infuscated at the tip. Front and 

 middle tarsi elongated, slender, yellow, infuscated from the tip of 

 first joint ; hind ones shorter and thicker, wholly infuscated. 

 First joint longer than the following one, on its under surface with 

 a long slender upright bristle. Front pulvilli a little enlarged. 

 Wings large, wide toward the apex, yellow before the third vein. 

 The first and second veins are rather far from the costa, and enter 

 it at a less acute angle than usual. The third vein runs close to 

 the second to its end, then turns with a strong curve backward, 

 reaching the margin just before the apex. The last section of the 

 fourth vein in the shape of a gentle double curve, ending just 

 behind the apex. 



$ . Front as in the male. Face rather wide, the suture distinct, 

 less pollinose than in the male. Hind metatarsus without the

 vein ; venation exactly like that of Eutaraus aidicus, Meig., in 

 Loew's Monograph, pi. vi., 28 c. 



Length 3"5-5"5 mm. ; of wing, 3-43 mm. 



Numerous specimens of both sexes. Sea level to 

 1500 feet. March aud May. One specimen labelled 

 " Forest by stream." 



The venation of the mole varies from that described to 

 a form like that of the female, 



EUTARSUS.
