lateral ocelli and broadly expanded at their lower ends into a 

 V-shaped frontal crest, broadly and squarely broken at middle ; the 

 area ahove the frontal crest slightly concave below, deep around the 

 median ocullus, the walls bounding it here slanting, rather abrupt 

 and high ; the V-shaped furrow wanting ; the median fovea a five- 

 sided area, narrower above, enclosed by the frontal crest and the 

 elevated upper end of the hypoclypeal area, with a narrow furrow 

 extending to the antennal fovea; the hypoclypeal area strongly 

 elevated at its upper end, with a ridge at middle, uniform in width 

 and height, and longer than wide ; the puncture on each side of 

 the front, near the middle of the front, broad and somewhat shallow ; 

 the area between the eyes and the pentagonal area almost fiat ; the 

 vertical portion of the antennal furrow linear, extending to the 

 lateral ocelli ; the interocular furrow completely wanting ; the 

 antennae with distinct segmentation, the first and second segments 

 together two-thirds the length of the third, the third segment one 

 and one-fifth times as long as the fourth, the fifth almost as long as 

 the fourth, the sixth five-sixths of the fifth, the seventh, eighth and 

 ninth subequa), slightly shorter than the sixth, the ninth much nar- 

 rower than the eighth ; with straight sides and bluntly rounded at 

 apex ; the thorax polished ; the wings hyaline, the veins and the 

 inner margin of the stigma brownish, the costa and the outer margin 

 of the stigma darker ; the front wings with the free part of R 4 twice 

 as long as the free part of R 5 ; the free part of R 4 and the radial 

 cross-vein straight ; the greatest length of the cell R 4 one and four- 

 fifth times the greatest length of the cell R 5 ; the legs finely seri- 

 ceous ; the posterior metatarsus slightly longer than all the following 

 segments together, the second segment two-fifths the length of the 

 metatarsus, the third segment subequal to the second, and the fourth 

 one-half the length of the third ; the saw-guides straight above, 

 slightly convex below and broadly convexly rounded, somewhat 

 truncated at apex above. Length. 4.5 mm. Habitat: Ithaca, 

 N. Y lata, n. sp. 



Hypoclypeal area broadly convex, not with an elevated ridge at 

 middle ; body black, with the legs below the knees paler, strongly 

 infuscated ; the walls of the pentagonal area low and rounded, 

 somewhat elevated in the region of the lateral ocelli, but fiat on top,
