of the wing-cases. Mesotliorax massive, very convex dorsally. 

 Abdominal segments devoid of spines, but with setae 

 corresponding to those of the larva. Cremaster apparatus 

 consists of two hooks on broad, conical bases ; hooks sharp, 

 curved and directed cephalo-ventrally. 



Labrum transverse, short, sulcate along median line, 

 transversely striate; paraclypeals distinct, triangular, rugose. 

 Labium large, labial lobes not distinct ; maxillary palpi large, 

 triangular. Antennal cases broad, showing pectinations of 

 antennte, reaching to the end of the first legs. Pronotura 

 finely transversely striated, mesonotum faintly so, very convex 

 at median part; inetanotum ii'regularly sulcate. Abdominal 

 segments sulcate transversely, with membranous art (inter- 

 segmental) lai-ge, lighter-coloured and smooth. Abdominal 

 segments 3 to 6 with a row of minute teeth at posterior edge ; 

 abd. 4 to 8 with a dorsal row of stronger spines along anterior 

 edge, which spines reach their greatest development on the 

 8th segment. On segment 9 the spiracles are prominent and 

 situated on lateral prominences. The cremaster consists of 

 two sharp, curved spines, the bases of which are elliptical 

 and continuous in the median line. 



Female Pupa. — Length 5'5 mm., width 1'5 mm., cylin- 

 drical ; posterior part from 7th abdominal segment abruptly 

 rounded; from the 6tli abdominal segment gradually and 

 uniformly tapering anteriorly (text-fig. 21, c, d). Colour 

 reddish-brown. Abdominal segments smooth, with apparently 

 a total absence of hooks, spines, and striations. Dorsal aspect 

 of head, pro- and mesothorax finely spinulate. A very slight 

 median carina on pi'o- and mesothorax. Head deflected ven- 

 trally, prothorax projecting beyond the head in front. 

 Ventral surface of head very much wrinkled, so as to almost 

 totally obscure the various parts. Legs indicated by a bilobed 

 median ventral process on pro- and mesothorax, on the meta- 

 thorax by two processes, united at their bases. 



Adult Female. — Apterous, vermiform, cylindrical, an- 

 terior part tapering gradually from the 3rd abdominal segment 

 anteriorly, posterior part abruptly rounded from the end of
