Wing shape. Hind \\in» oval, somewhat produced at the anal angle, outer margin slightly 

 undulating between the ends of veins 6 to 3, a delicate tail at the end of vein 2, a much longer 

 one at the end of vein ib, a small lobe at the anal angle. Abdominal margin excised between 

 the lobe and the end of vein ia. No secondary male sexual characters. 



Wing venation (Text-fig. 290). Fore wing with only 10 veins. 



Male genitalia (Text-fig. 111). Incus composed of two subtriangular lobes with rounded 

 apices ; subunci long, evenly curved, tapering gradually to a blunt apex ; tegumen large 

 only slightly notched on its posterior margin ; vinculum broad above, narrower below ; lower 

 fultura articulated to the base of the valves and composed of two curved arms connected at 

 their apices by a membrane, thus forming a complete ring around the penis ; valves sub- 

 rectangular, widened at the apices and bearing on their distal edge two stout teeth of unequal 

 length ; penis elongate, curved, the basal portion widely open, the external portion tapering 

 regularly to a blunt apex ; vesica with two long, sharp-pointed spines ; uncus and distal 

 portion of the valves hairy, 



Stugeta bowkeri is remarkable in that some of its geographical races show sharp 

 dilhrences in the terminal contour of the valves (see Stempffer & Bennett, 1958, 

 20 : 1266, figs 14, 15). The male genitalia of the other species of the subgenus are 

 very close to those of bowkeri. 



The early stages of S. bowkeri have been described by Murray (1935 : 72) and 

 Pinhey (1949 : 103) ; those of S. marmorea olalae by Jackson (1937, Trans. R. ent. 

 Soc. Lond. 86 : 213).
