OKEITICUS KIRBYI. ] 13 



strong ; the abdominal feet are ten in number, two 

 of them anal. The body consists of twelve segments, 

 the sides somewhat prominent, the whole with 

 thinly scattered hairs. The three anterior, segments 

 and the head are yellowish variegated with brown 

 marks, the rest of a dull livid colour. When the 

 larva is alarmed, it very rapidly shuts up the purse- 

 like aperture of its dwelling by means of its man- 

 dibles and fore legs, and thus remains in security 

 suspended only by a few threads. (Plate IX. fig. 1 

 represents a female larva in its case, in the act of 

 creeping. Fig. 2, the same larva withdrawn from its 

 case.) Having attained its full growth, and about 

 to undergo metamorphosis, it fixes one end of its 

 habitaculum firmly to a branch by means of silk 

 threads spun for the purpose, and allowing itself to 

 hang perpendicularly, awaits in this position the 

 pupal sleep. (Plate IX. fig. 3 represents the habi- 

 taculum of an adult male thus suspended.) The 

 pupa of the male is elongated, brown, the abdomi- 

 nal segments with a rust-coloured ring, the front 

 somewhat carinated, and each segment furnished 

 with a double series of dorsal spinulae ; that of the 

 female is of the same colour, but much thicker. 



When the male appears in the winged state, he 

 is found to be of a uniform black colour glossed with 

 purple ; the upper wings rather narrow and elonga- 

 ted, the under pair small and slightly produced at 

 the anal angle. The abdomen is extensile and 

 elongated; tarsi rufescent ; mouth pale; antenna? 

 strongly pectinated from the base to the middle,
