broadly convex ; their greatest width is at the distal three-fourths and 

 is narrower than the length of the longest marginal cilia ; the discal 

 ciliation is coarse but uniform and is arranged only in about from five 

 to seven longitudinal lines ; along each margin very fine and short 

 cilia are interspersed between the long, primary marginal ciliation ; 

 proximad, the discal ciliation of the fore wing is limited by an oblique 

 line of cilia as in Atiaphoidea which crosses the wing caudo-distad from 

 about a point at the proximal two-thirds of the marginal vein. Proxi- 

 mad of this line, the wing is naked excepting for the presence of a 

 single, distinct seta, centrally situated at the base of the marginal vein. 

 Marginal cilia of the fore wing where longest (disto-caudad) one and a 

 half times longer than greatest width of the blade, slightly longer than 

 the longest cilia of the posterior wing and about sixty around the whole 

 blade. Marginal vein long, about four and a half times longer than 

 broad, its distal end free, concaved, ending in an obtuse point pro- 

 jected disto-cephalad. Fore wings ending in an obtuse point. Poste- 

 rior wings narrow, curved slightly in a direction opposite to that of the 

 fore wings, the cephalic margin broadly concave ; acuminate, subacute 

 at apex ; its caudal marginal cilia long, much longer than the greatest 

 width of the fore wing, at least four times longer than the average 

 width of the blade of the posterior wing, those of the cephalic margin 

 short, yet longer than the greatest width of the blade. Its discal cilia- 

 tion consisting only of the paired lines along each edge, absent in the 

 disk; two small booklets. Marginal vein of fore wing bearing rather 

 numerous setae, irregularly placed (about nine to ten). 



Thorax much larger (about twice) than the abdomen, the latter ses- 

 sile, small, ovate, the valves of the ovipositor not conspicuous. Legs 

 with the cephalic tibia; short, slightly shorter than the cephalic femora, 

 the intermediate and caudal tibiae slender, distinctly longer than their 

 respective femora. Tarsi 4-jointed, the proximal joints short, the 

 others shortening distad but the proximal joint in the cephalic tarsi is 

 twice larger than the second joint of those tarsi and bears a strigil ; 

 tibial spurs of cephalic tibiae single, curved, comparatively large, 

 forked at tip ; those of the other legs paired (?) and extremely minute, 

 apparently absent. 



Antennae 9-jointed, with a solid club. Scape somewhat longer than 

 the pedicel and first two funicle joints combined ; pedicel obconic, 

 very much larger than the proximal funicle joint and longer than all 

 funicle joints excepting the second, third and sixth, to either of which 

 it is subequal in length ; funicle joints 1, 2 and 3 slender, 4 and 5 and 

 6 thickening distad ; 1 minute, barely longer than wide ; 2 longest, 

 slender, three and a half times longer than 1 ; 3 slightly shorter and 

 very slightly thicker ; 4 still shorter, thicker, cylindrical ovate ; 5 slightly 

 longer and thicker and 6 widest, longer, as long as joint 3 or even 2 

 (2 and 3 sometimes equal); 6 still narrower than the pedicel; club
