Adult female brown, but covered with a dense pubescence 

 of short and long hairs, so that the general appearance is 

 greyish. Form elliptical, thick, segmented, as usual in the 

 genus. Length varying from lin. to ^in., but shrivelling at 

 gestation. There is a good deal of very white cotton on most 

 specimens. Antennae with nine subequal joints, the third and 

 ninth rather the longest ; the ninth is fusiform ; all the joints 

 bear some short hairs. Feet long, black ; tibia a little more 

 than twice as long as the tarsus ; trochanter with two long 

 hairs, one longer than the other ; the inner edges of both 

 tibia and tarsus bear several spines. Eostrum large ; mentum 

 conical, dimerous. The dermal pubescence consists of im- 

 mense numbers of short hairs and a good many much longer, 

 interspersed with numerous small circular multilocular spin- 

 neret orifices. Anogenital ring without hairs ; there are two 

 longish terminal setaB. 



Second female stage not observed. 



Larva greyish - brown, elliptical, active ; length, about 

 ^L-iu. Antennge black, thick, with five joints, of which the 

 fifth and the third are the longest ; the fifth is broadly fusi- 

 form, and bears several long thick hairs. Feet black ; the 

 tibia and tarsus are subequal, the tarsus a little the longer ; 

 both bear many hairs ; there is only one digitule, which is a 

 thick short bristle on the claw. Mentum long, conical, dimer- 

 ous. The body is covered with a dense pubescence of short 

 hairs, and the margin bears many longish setae, which are 

 most numerous and longest at the posterior extremity. 



Eggs large, at fii'st yellow, later dark-brown. 



The male pupa is contained in a cylmdrical sac of rather 

 solid white cotton, the anterior end rather truncate, the pos- 

 terior end regularly curved. Within the cotton the skin or 

 case of the pupa is thin and transparent, covered with great 

 numbers of short hairs interspersed with circular multilocular 

 spinnerets. After the adult has emerged the exuviae of the 

 pupal antennae and feet are dark-brown. The antennae have 

 six joints, of which the third and sixth are the longest ; the 

 sixth is fusiform. The feet are as in the adult female, 

 as also the rostrum and mentum. Eyes tubercular and 

 smooth. 



The adult male has a length of about iin. for the body, 

 with an expanse of wings of about -^in. The head and thorax 

 are very dark-brown, almost black, with red patches; abdomen
