Parasa fraterna, Gr. Larva. 



Ovate elliptic in outline. Body chestnut brown, darker in front and at the sides, 

 the margin of the dorsum elevated into a sharp ridge. On segments 3, 4 and 5 are 

 two retractile tubercles, bearing bunches of sordid white spines, those of the third 

 segment being much smaller than the others. The loth and 12th segments are fur- 

 nisiied with similar tubercles, those of the 12th being the smallest. The dorsal region 

 is paL" chestnut brown, with some indistinct waved streaks of a slightly daiker shade. 

 Head pitchy, mouth parts paler. The anal segment is produced into a long spine. 

 The spiracles are dnil yellowish, the underside also dull yellow, and the lower lateral 

 region reddish yellow. 



Length 15 mm. Width at 5th segment 5 mm. 



Hyparpax aurora. Abb. Smith. Larval stairs. 



After ist moult. — General color, yellowish brick red. Head constricted at junc- 

 tion of the 2nd segment, yellowish white, mottled with brick red. and segment dull 

 white, with double dorsal line, enclosing some small reddish blotches, and two small 

 reddish piliferous tubercles. The posterior margin of this segment is darker than the 

 anterior. 3rd segment bright yellow, with small piliferous tubercles of the same 

 color. 4th segment raised in the centre, with small double piliferous hump. 5th with 

 yellow blotch in centre, irregular in shape, spreading slightly on the side of dorsum. 

 6th, the yellow is here wider, with narrow red stripe. 7th, 8th, 9th, the red stripe 

 becomes gradually wider, leaving the yellow only on the sides. loth and nth, the 

 red stripe here narrows in front and widens behind, being elevated into rather a high 

 hump in centre of the dorsum. The anal segments are elevated in repose, as is 

 the manner of Cerura, the last segment being furnished with two rather short 

 processes. 



Length 12 mm. 



After 2nd moult. — Head as before, but the markings a little darker, and more 

 spread over the surface. 2nd, 3rd and 4th segments, as also the whole of the lateral 

 region, are now pale yellowish green, the dorsal red mark being widest on 2nd and 

 becoming obsolete on the 4th. On the 5th the hump is larger than before, and there 

 are 4 piliferous tubercular spots, the anterior pair highest and largest. The red dor.al 

 patch is very apparent on 5th, 6th and 7th, narrows on 8lh, spreads again on 9th, 

 loth and nth, being constricted on loth. I2th and anal segment are pale yellow 

 with reddish mottlings. The anal processes are also short, yellowish, mottled with 

 yellowish. Whole body with small shining tubercular spots. Feet and legs reddish. 

 The colors are somewhat confused, blending into each other, particularly on the 

 lateral region. 



Length 22 mm. 



After ^rd moult . — -The colors are now more clearly defined. 2nd and 3rd have 

 the red coloring edged with bright yellow, and reduced to a mere point on the post- 

 erior edge. 4th segment wholly pale yellowish green. Lateral region also pale 

 yellowish green. 5th segment produced into a hump, which bears anteriorly two 

 rather high tubercles, the reddish color being broad posteriorly, and narrow anteriorly. 

 6th has the red a little constricted— 2 tubercular spots yellow, rather large, and a 

 smaller pair of the same color beside them. On 7th, the red patch is wide ; on 8th, 

 narrow ; on 9th and loth again widened, then narrow and almost obsolete at anal 

 segment, which has 2 small processes, tipped with red. The whole of the red color 

 on the dorsal region is broadly shaded with bright yellow, between it and the green
