The ANSORGE 1 -Group 



In fore wing, venation distinct in the proximity of vein M 2 to M„ the upper and lower 

 discocellulars usually being in the ratio of i : 2. In the male genitalia the dorsal process 

 of the valve is simple and without a setose projection in the basal fourth and the dorsal margin 

 is extended in digitate form; the fulcrum is reduced and subequal in length to the aedeagus. 

 In the female genitalia the ductus bursae is well developed, equal in length to the corpus 

 bursae. The group includes only one species.

0*$ (PI. 95, fig. 841). Hyaline proximal two-thirds of each wing tinged with buff irrorate 

 with light brown, densely on costa of fore wing and on posterior margin of each wing, and 

 finely edged distally with greyish brown. Terminal non-hyaline area light yellow (pi. 4, A4) 

 irrorate with brownish orange (pi. 5, C5), often forming a dense band bordering hyaline area; 

 subterminal fascia light yellow edged with grey, weakly defined; termen slenderly grey, often 

 broken and represented as interneural spots. Underside marked similarly to upperside. 

 Male hind tibia dilate, enclosing dense tuft of long hair scales. 



$ genitalia (Text-figs 13, 14). Uncus tapered from bulbous base; dorsal surface setose. 

 Ventral plate of gnathus weakly developed. Dorsal process of valve slightly dilate before 

 tapering apicad; apex of valve concave, dorsal margin produced in digitate form. Apical 

 fourth of aedeagus with short, thorn-like projection; fulcrum subequal in length to aedeagus, 

 bilobate at apex. Vesica with small area of dense, short scobination. 



$ genitalia (PI. 2, figs 459, 460). Sterigma with a pair of short, blade-like processes, one at 

 each side of ostial opening. Ductus bursae sclerotized posteriorly, equal in length to 

 corpus bursae. 



Measurements. Fore wing: ^9.0-10.5 mm; $ 9-1 1 mm. Antenna! pectinations: $ 16 X, 

 $ 6 X diameter of shaft. 



In colour and pattern reminiscent of ordinaria Bethune-Baker, psammites Fletcher 

 and ochrata Warren in the pulverosa-group; distinguished by the clearly defined, 

 darkly irrorate band immediately distad of the hyaline area, the absence of dark grey 

 or black markings in the non-hyaline terminal area and the denser light brown irrora- 

 tion of the hyaline area; distinguished further in the venation by the more anteriorly 

 placed vein M 2 on the fore wing, the upper and lower discocellulars being usually
