 the antennal fovea, more or less wedge-shaped in outline ; the 

 hypoclypeal area convexly flattened, slighthy elevated adjacent to 

 the middle fovea ; the postocular area about a half wider than long, 

 strongly, convexly, elevated ; the vertical portion of the antennal 

 furrows linear, deep, parallel, the posterior orbits much lower than 

 the postocular area ; the interocular furrow faintly indicated at 

 sides and wanting at middle; the antennae with the first and second 

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

 one and one half times as long as the fourth, the fifth slightly 

 shorter than the fourth, the sixth two-thirds the length of the fifth, 

 the sixth, seventh and the eighth subequal, and the ninth shorter 

 than the eighth, broad, bluntly rounded at apex ; the thorax polished, 

 finely setaceous and pitted ; the front wings rather strongly infus- 

 cated out as far as the apex of the stigma, the remainder and the 

 hind wings hyaline, the veins and stigma mfuscated, the stigma 

 darker on the outer half; the front wings with the free part of 1\, 

 slightly longer than the free part of R 5 and slightly bowed inwardly; 

 the radial i un slightly bowed outwardly ; the greatest length of 

 the cell R- slightly more than two-thirds the greatest length of the cell 

 R 4 ; the legs finely sericeous ; the posterior metatarsus much shorter 

 than all the following segments together, the second segment 

 slightly longer than the third, the fourth less than one-half as long

 front and middle legs below the knees, the basal half of the hind 

 tibiae, and their tar^i more or less, white ; the walls of the pentag- 

 onal area distinct, their ventral ends strongly dilated, forming a 

 frontal crest, broadly interrupted at middle by a deep, wedge-shaped 

 middle fovea;. the V-shaped furrow distinct, narrow, with high and 

 straight walls ; the ocellar basin much longer than broad, the crest 

 of the walls bounding it bowed outwardly ; the walls of the pentag-
