their lower ends dilated, diverging like an inverted V, with straight 

 sides, broadly rounded ; the frontal crest hardly broken at middle, 

 and somewhat elevated above the flattened area above it ; the area 

 above the frontal crest flat on its lower half, strongly concave 

 around the median ocellus and ending in a. well-marked V-shaped 

 furrow; the median fovea a tiiangular depressed area, with arms 

 extending to the antennal fovea and another through the slight break 

 in the frontal crest ; the hypoclypeal area broad, uniformly convex, 

 its upper end strongly elevated ; the puncture on each side of the 

 front small, with straight sides, well-like, located at the median end 

 of the ridge of each side forming the frontal crest ; the postocular 

 area uniformly convex, much broader than long ; the front between 

 the eyes and the pentagonal area concave \ the vertical portion of 

 the antennal furrows deep, linear, extending to the lateral ocelli ; 

 the interocular furrow obsolete at middle, faintly indicated at sides ; 

 the antenna- with distinct segmentation, the first and second 

 segments together two-thirds the length of the third, the third 

 segment one and one-third times the length of the fourth, the fifth 

 and sixth subequal, slightly shorter than the fourth, the seventh, 

 eighth and ninth subequal and slightly shorter than the sixth, the 

 fourth to sixth segments broadest, gradually narrowing to the apex, 

 the ninth segment with straight sides and truncate at apex ; the 

 thorax polished and finely sericeous ; the wings hyaline, slightly 

 infuscated below the stigma, the veins, including the cost and the 

 stigma, brownish ; the front wings with the free part of R t nearly 

 twice as long as the free part of R„ ; the free part of R 4 bowed in- 

 wardly, and the radial cross-vein straight ; the greatest length of the 

 cell R t slightly more than twice the greatest length of the cell R 5 ; 

 the legs finely sericeous ; the posterior metatarsus four-fifths the 

 length of all the following segments together, the second segment 

 one-third the length of the metatarsus, the third and fourth segments 

 together subequal to the second ; the saw-guides straight on their 

 upper and lower margins, obliquely truncated and with a blunt 

 point at apex above. Length, 5.5 mm. Habitat: Oswego, N. Y.
