about 20 mm. in length ; cylindrical, head and two following- 

 segments narrower than rest of body; head bright reddish-l)rown. 

 eyes l)lack ; cervical shield blackish-brown ; segments three to six. 

 blackish, becoming paler posteriorly ; remaining segments more or 

 less fuscous with somewhat of a purplish tinge : tubercles i, ii. 

 and iii, large, circular, slightly convex, a dark dot at base of 

 hairs ; other tubercles smaller ; Hairs long, reddish ; spiracles dark 

 with pale centers, those on segments three to eleven, minute. 



The pupa (Plate IV, Fig. 2) is formed in a slight cocoon of 

 white silk where the larva has lived. It is about 7 mm. long; 

 luiiform, medium lirown ; antenna- and wing-cases extending to 

 near the apex of fourth abdominal segment ; on dorsum of fiftn 

 abdominal segment is a band near the base, having longitudinal 

 striations ; cremaster flattenefl dorsiventrallw abruptly con- 

 tracted to a median spine which has a double hook at the tip 

 fastened into the silk of the cocoon. The pupal period is thirteen 

 to fifteen da>s. Dther details of its life historv are not known..

"Head chestnut-brown ; palpi widely divergent, whitish, with an oblique 

 pale brown mark on each side near the end of the second joint, and two 

 or three brownish spots on the sides of the apical joint. Antennae witln 

 white and fuscous annulations : the basal joint elongate, chestnut-brown. 

 Forewings chestnut-brown, slightly shaded with fuscous towards the 

 costal margin: a whitish-ochreous streak at the base of the dorsal margin, 

 followed by two or three other smaller ones along the dorsal margin (in 

 some specimens these are obsolete) ; above the dorsal margin are two 

 oblique whitish-ochreous streaks, the first before the middle, the second 

 before the anal angle. A similar streak from the costal margin immedi- 

 ately before the apex is outwardly margined by a streak of black scales, 

 t!ie apex and apical margin being also black: there is also a faint fuscous 

 streak running downwards through the cilia below the apex. On the 

 cell are tw(i elongate patches of black scales, one immediately before the 

 middle of the wing, the other halfway between this and the base. Fringes 

 grey, with a slight yellowish tinge. Hind \vings pale greyish. Hind 

 tibiae greyish-white, outwardly fuscous: hind tarsi whitish, with a wide
