marginal vein, only about a tenth as long as the greatest wing width, 

 the longest about thrice the size of the discal cilia and not any longer 

 (subequal) than those of the posterior margin of the hind wings. Mar- 

 ginal vein very long for the genus, about twelve times longer than 

 wide, about a fourth shorter than the slender submarginal vein, mod- 

 erately broad, distad leaving the cephalic wing margin and terminat- 

 ing like a stigmal vein, the independent portion moderately short, 

 curved concavely (its cephalic margin concave), the whole comprising 

 about a fourth the length of the marginal vein and at its base there 

 are two equal pustular (clear) spots in a line transversely and three 

 more in its apex ; if treated as a stigmal vein it would be a moderately 

 long, distinct one, without a knob and ending in an obtuse point. 

 Posterior wings curved, acuminate, the apex acute, its discal ciliation 

 consisting of a double row of cilia along each edge, the outer row 

 more or less obscure, its cilia inclined outward, and distad three more 

 or less regular rows, two short, not containing more than five or six 

 cilia, the third (caudal) one longer, coming down the wing blade irre- 

 gularly to its extreme base, crossing over before reaching the vena- 

 tion ; or the first and second of these lines may be equal in length, not 

 extending far proximad but much longer than the third ; there are a 

 few additional minute cilia proximad, caudad and disto-caudad of the 

 venation. The latter straight, long, slender, slightly widening at tip. 

 Marginal cilia like those of the fore wing, the longest subequal to the 

 greatest width of the blade (across the apex of the venation). 



Legs normal, the tarsi 5-jointed, the proximal tarsal joint much the 

 longest but barely equal to any two of the others combined excepting 

 the fourth and fifth, the distal four sebequal, the fourth a little shorter 

 than the others ; tibite all slender and longer than the femora ; coxa; 

 large. Cephalic tibial spur long, slender, curved and forked at tip, 

 forming a strigil and as long as the proximal tarsal joint (cephalic 

 legs); other tibial spurs single, straight, shorter; trochanters 2-jointed. 

 Cephalic proximal tarsal joint armed beneath with a row of stiff 

 bristles. Caudal coxa3 conical. Posterior femora moderately stout. 



Abdomen ovate, about equal in length to the head and thorax taken 

 together, sessile, the ovipositor reaching to tip, not exserted, only its 

 tip projecting slightly. Metathoracic spiracle minute, round. Body 

 apparently without sculpture and with no conspicuous pubescence. 



Antennae 11-jointed, filiform-clavate, moderately pubescent with 

 short grayish hairs. Bulb of scape slender, moderately long, straight. 

 Scape slightly longer than pedicel and first and second funicle joints 

 combined, about as long as the first three funicle joints together, 

 slightly convexed beneath ; pedicel short obconic, wider but not much 

 longer than the proximal funicle joint ; the latter shortest, distinctly 

 longer than wide, cj^lindrical ; funicle joint 2 longer and stouter ; 3, 4 

 and 5 subequal, slightly longer and wider, 6 and 7 subequal, a fourth 

 shorter, stouter, wider than long, about equal in length to 1 but dis-
