Fore wing (pi. VI, f. 8) lanceolate, sharply acute at apex, with 

 tornus indistinct, costa straight, termen and dorsum forming a slightly 

 excurved line. Costal vein visible at the very base of wing. Subcostal 

 developed at base, obliterating towards middle of the wing and not 

 reaching costa. Radial vein at base weak and connected with sub- 

 costal, but strongly developed in the median cell and bearing five 

 rami; R^ beginning from the second third of the R; Rg from the end 

 of it; Я> right in the middle between them; R^, Ro and Rg free and 

 parallel; R2+3+4+5 is equal, therefore, to R3+4+5; R4+5 very short; R4 

 and R5 stalked with M^ and Mo and reaching costa near apex; the stalk 

 R4+5+MH-2 long, beginning from the upper angle of the median cell 

 RCD and running to apex; R^+j+Mj nearly two times shorter; Rj-f-Mi 

 nearly equal to R^+j+Mj ; R5 and M^ very short, diverging at fhe very 

 apex, this latter lying between them; Mo nearly parallel to Rj + M^; Dg 

 very short and indistinct; M;, parallel to Ri+s+Mj-j-o; D4 hardly visible. 

 Median vein undeveloped, as well as cubital, this latter visible at base 

 only. Ci at its origin almost invisible and equal to D4, terminally 

 well developed, parallel to M3 and slightly excurved downwards; C2 

 running in the same direction. First anal vein visible at the termen 

 only. Second and third anal fully developed, but entirely connected, 

 with no fork at base. Retinaculum and cteniolum well developed. 



Hind wing (pi. VI, f. 9) narrow, lanceolate, almost linear, with 

 apex acute and attenuated, tornus indistinct, costa straight and slightly 

 excurved at base. Costal vein invisible. „Subcostal" (S + Ri) well 

 marked at base, then approaching costa and fused with it about the 

 middle of costa. Radial hardly visible and more marked in its distal 

 part near costa; „R" (Ro+a) extremely short, terminating in costa. Me- 

 dian vein invisible; „M/ (R44.54-M1) well developed, originating from 

 „R" and running to termen below apex; Mo parallel to „M^" ; Do and 

 D3 invisible; M3 parallel and equal to Mg; D4 well marked. Cubital 

 vein ill developed, but visible; C^ and C2 well marked, short, parallel 

 to Mo and M3. First anal well developed, straight and short. Second 

 and third anal absent. Frenulum strong, in the female consisting of 

 two spines. 



Legs (pi. VII, ff. 10 — 12) normal, hind ones elongated; epiphysis 

 of the fore tibia long; fifth tarsal joint of the middle and hind leg 

 rather widened. Calcaria long, the anterior shorter than the posterior; 

 the upper pair on hind tibia situated before middle of the latter. 



Abdominal segments (pi. V and VI, ff. 6, 13—16) normal. 

 The male terminal segments and copulatory apparatus 

 (pi. VI, ff. 13 — 14) peculiar. Ninth tergite distinctly separated, ninth 

 sternite narrow, with saccus very long, narrow, tubuliform, slightly 

 curved at oral end. Tenth segment extraordinarily large, forming a
