is produced into a conical point, and the second abdominal segment 
(which extends to the extremity of the wing-cases), as well as the 
third, fourth and fifth, are furnished on the back with a transverse 
series of recurved hooklets close to the hind margin. Those on the 
fourth segment are finer than those on the preceding ; moreover the 
fourth, fifth, sixth, seventh and eighth segments are armed on the 
back with a series of spines at the base of each, directed backwards, 
those of the fourth segment being the most slender.

Exclusive of the peculiar colour of the males, this sex is remarkable 
for the shortness of the wings, which gives the insect somewhat the 
appearance of the lackey moth (Clistocampa Neustria). The antennze 
consist of about forty joints, and they are bipectinated to the tip. 
The veining of the wings agrees almost precisely with that of O. 
Saundersii. The fore legs have the tibiee furnished with the elongated 
spur at the base. 
From a few fragments of the exuvise of the larva of the male in 
one of the cases, it is evident that the head and thoracic segments 
were maculated with yellow and black, but the pieces are so much 
injured that I cannot arrange them into segments. 
The pupa of the male is of a light chestnut colour, with the wing- 
cases darker ; thehead-case is carinated above, and the dorsal portion of 
the abdominal segments is strongly striated or wrinkled transversely. 
The second and third segments are rugose at the base on the back, 
the fourth and four following are armed with a row of spines at the 
base, gradually becoming stronger on the hinder segments; the 
third, fourth and fifth have a transverse row of recurved hooklets 
on the hind part of the back of each. The fourth, fifth, and sixth 
beneath exhibit the appearance of a pair of pro-legs. 
The female pupa is of a black colour, chestnut beneath and at the 
edges of the segments ; it is elongate-ovate, the first segment behind 
the head slightly carinated ; the abdominal segments are finely striated 
transversely, the base of each being rather rugose, and the extremity 
of the sixth and three following segments have a row of very fine 
recurved hooklets. The extremity of the body beneath is destitute 
of the two horny points observed in the pupa of the male.
