CLANIS. 147 



•curved downwards and pointed, with the edges irregularly 

 notched ; in a lateral view (fig. 28 C) the lobe appears rather 

 dilated before the apex, convex. The sternite membrana- 

 ceous laterally ; the mesial lobe is subtruncate, trapeziform, 

 with the edges somewhat rounded. The harpe (fig. 28 E) 

 consists of a mesial ridge which is deeply curved twice and 

 distally raised to a flattened process, which curves basad and 

 somewhat resembles the process of titan ; dorsal process 

 short and broad, and beset with rough warts which bear each 

 a short bristle. 



$. Eighth tergite (fig. 28 F) short, broadly sinuate, the 

 sinus rounded, the sides projecting, rounded. Vaginal 

 •orifice surrounded by two folds ; the post -vaginal plate broadly 

 rounded. 



Hab. E. Himalayas. We have bred it in the Khasi Hills, 

 where eggs and larvae are common at an elevation of from 

 4,000 to 5,000 feet in thickly wooded areas with heavy 

 rainfall. 



Egg. — Broadly ovoid, surface smooth and shining ; colour 

 ivory-yellow. Length 2-5 mm. ; breadth 2 mm. 



Larva : — 



1st instar. Head large and round, body cylindrical, of less 

 •diameter than head ; horn straight, of medium length, the 

 tip shortly, broadly bifid ; on emerging from the egg head and 

 T^ody pale yellow and horn pale grey ; after feeding head yellow, 

 body yellowish-green, horn reddish-brown with a whitish 

 median ring and the tip black. 2nd instar. Head broadly 

 triangular with a process rising from the apex of each lobe, 

 these processes half as long as rest of head and diverging 

 from their bases ; horn straight, of medium length ; head with 

 a line of tubercles separating face from cheek ; body with 

 transverse rows of small tubercles, one row along each secondary 

 ring ; narrow subdorsal and subspiracular stripes of larger 

 tubercles on segments 2 to 4, the latter stripe meeting the 

 lower end of the oblique stripe on 5 ; narrow oblique stripes 

 formed of larger tubercles on 5 to 11, extending backwards 

 to near dorsal line of body, that on 11 running across 12 to 

 base of horn ; the head green, the processes red-brown, the 

 line of tubercles yellow ; body bright green, the transverse 

 rows of tubercles white, the larger tubercles forming the 

 stripes yellow. In the succeeding iustars there is little change, 

 •except that the head-processes and the horn become propor- 

 tionally shorter and the tubercles less prominent. 



5th instar. Head large and deep, rounded- triangular, dorsal 

 line of vertex depressed, the processes reduced to a small 

 tubercle on the apex of each lobe. Surface of head shining ; 

 .a fine of large, flat, oval tubercles running from apex of each
