 and then much more sharply defined than in masuriensis. 

 Expanse : $, 48 mm. 



$. Anal tergite less compressed than in masuriensis, sternite^ 

 broader and more sharply narrowed to a point. Harpe 

 with a basal process which is hollow, open above, the distal 

 part of harpe raised to a sinuate ridge ; above this a hairy 

 process on the clasper. Penis-sheath with a long flat process,

Fig. 86. — Gurelca himachala himachala (Butl.), <$ holotype. 



Hab. E. Himalayas to China and Japan. We have bred 

 the subspecies in the Khasi Hills at an elevation of about 

 5,000 feet. The larvse are fairly common during the monsoon, 

 but not so common as those of hyas, with which they are 

 sometimes associated on the same plant. 



Larva : — 



Final instar. Head nearly oval ; true clypeus narrow,, 

 about one-half length of head, basal angles hardly rounded ; 

 false clypeus narrow, its apex forming a gothic arch over 

 apex of true clypeus ; labrum one-half length of and 

 slightly broader than clypeus ; ligula narrow kidney- shaped ; 

 mandible with the cutting-edge toothed ; eyes with 1 and 2 

 forming an angle of about 120° with 3, 4 and 6, which are 

 in a straight line ; 1,2 and 3 about one eye -diameter apart, 

 4 slightly further from 3 ; 6 tAvo diameters from 4 ; 5 forming 

 an equilateral triangle with 4 and 6 ; eye 3 larger than the rest. 

 Surface of head dull and set with short, curved, translucent 

 hairs, each rising from a minute tubercle. Body dull and 

 smooth. Horn very long, fairly thick at base, tapering gently 

 to beyond middle and then thickening gently, tip strongly
