The most of the following descriptions have been in manuscript for 

 many months. The names in this paper and some others to be published 

 later are to be used in another place, and they are offered for publication 

 at this time for that reason. 



Faraxyela, n. gen. — Front wings with the free part of M arising dis- 

 tinctly before the point of separation of R and Scg, the free part of R5 

 distinctly shorter than R + Scg, frequently less than one-half the length of 

 R -f Scg; the hind wings with the free part of R5 present; clypeus triangular 

 in outline, the median portion two or three times as long as the lateral 

 portions; the antennae with the third segment longer than all the following 

 segments together ; the claws cleft, the two parts of the cleft parallel. 

 Type, Xyela tricolor Nort. 



Macroxyela bicolor^ n. sp. — Male : head with a flat depressed area 

 in front of the median ocellus, never crossed by the median fovea; median 

 fovea represented by a linear smooth spot only slightly if at all depressed 

 below the surface of the front ; the area of the head between the antennal 

 sockets and the ocellar farrow blackish and coarsely punctured, the re- 

 mainder of the head and the notum finely shagrined ; antennae with the 

 third segment five times as long as all the following segments together ; 

 the fourth and fifth segments subequal, each longer than any of the follow- 

 ing segments ; the body black with the clypeus, the labrum, the malar 

 space, the supraclypeal area, the basal plates at sides above the abdomen, 

 and the legs, rufous. Length, 8 mm. 



Habitat. — Columbus, Ohio. Professor J. S. Hine, collector. 



Differentiated from the males of all other species of the genus known 

 to me by the greater abundance of rufous. 



Macroxyela obsoleta, n. sp. — Female: head with a flat depressed area 

 in front of the median ocellus, never crossed by the median fovea; median 

 fovea a broad, flat, indistinct, depressed area, more distinct near the 

 median ocellus ; antennae with the third segment many times longer than 

 all the following segments together, with a black ring at base ; the fourth, 

 fifth and sixth segments subequal in length, the following segments shorter; 

 the head below the ocelli sparsely, coarsely punctured ; front wings with
