conspicuous, but three in number. The beak is brownish and 

 0.27 mm. long, extending to the mesocoxae. 



The prothorax is short ; the thorax is black, strongly arched, 

 and broad. It is so much arched that the prothorax can 

 scarcely be seen from a dorsal view. The wings are hyaline, 

 with brownish black veins. The stigma is grayish, 0.145 mm. 

 wide and 0.63 mm. long. A peculiar fold lies between the 

 costal and subcostal veins of the caudal wings, which is desig- 

 nated in the figure. Total wing expansion, 5.80 mm. Legs 

 are brownish black, hirsute ; distal half of the femora, distal 

 part of the tibia and all the tarsi black. Legs rather long in 

 proportion to the body. 



Abdomen is dark brown. Honey-tubes concolorous, almost 

 cylindrical, and 0.32 mm. long, or three times the length of the 

 tarsi. The style is black, hirsute, conical, and 0.09 mm. long, or 

 about one-fifth the length of the honey-tubes. Total length of 

 the body, 1.09 mm. 



This form was taken in October, and since only one specimen 

 was taken no adequate description or habit can be given. It 

 was found in company with Schizoneura corni, on the ventral 

 side of the leaves of the elm ( JJlmus americana) .
