contact with each other, their external margins slightly converging, 

 their apices roundedly truncate from within laterad. 



Genitalia of abd. seg. 2: (PI. Ill, figs. 4, 5). Anterior lamina 

 brown, low, entire, with a marginal row of brownish hairs; the other 

 genitalia darker. Anterior hamules bifid at tip, internal branch the 

 longer and more acute, interval separating it from external branch 

 elliptical, narrower at the mouth. Posterior hamules one-and-two-fifths 

 times as long as the anterior hamules, tapering to an acute apex. 

 Vesicle of the penis projecting subequally with the anterior hamules, 

 having on each side a stout antero-ventral angle of somewhat less 

 than oo degrees. Posterior margin of each auricle almost straight, 

 slightly convex, bearing 5-6 denticles. 



Wings barely smoky yellowish. Stigma dark reddish-brown within 

 black veins, surmounting 5-6 cells. Venation, including the costa, 

 black. Forewings with 20 (r), 18 (1) antenodals, the 7th (r) or 6th 

 (1) thicker, 14 (r), 15 (1) postnodals, two posttriangular rows in- 

 creasing near the level of the nodus with 7-8 marginal cells, a maxi- 

 mum of three rows of cells in the second cubital area. Hind wings with 

 13 (r), 14 (1) antenodals, the 6th thicker, 13 (r), 14 (1) postnodals, 

 3 posttriangular cells, then two rows, increasing near the level of 

 separation of Rs bridge from All +2, with 13-14 marginal cells, proxi- 

 mal row of postanal cells 5, distal row of 4, a maximum of five rows 

 of cells in the second cubital area, anal triangle 4-celled. 



Abdomen 33, hind wing 30, costal edge of stigma of fore wing 3.5 

 mm. 



Only the type male has been seen. This handsomely colored 

 species falls near E. cittainia and /:. i-ipcrinus in the synopsis 

 of species of Erpctogoinphus in the Biologia volume, pages 

 159-160. It differs from E. cutainia in the absence of an in- 

 ferior longitudinal carina on the basal third of the superior 

 appendages, in the strongly ventral curvature of the terminal 

 third of the same appendages and in the shape of their apices, 

 the apparent absence of a second pale antehumeral stripe sepa- 

 rating the dark antehumeral and humeral stripes, and of a 

 yellow line on the costa anteriorly, the greater number of ante- 

 and postnodals and the longer wings. 



From E. t'ipcrinns, E. scJiansi differs by the presence of 

 dark markings on the face, the stronger ventral curvature of 

 the terminal third of the superior appendages, the apparent 

 absence of a second pale antehumeral stripe the greater number 

 of ante- and postnodals, etc.
