The following descriptions have been drawn up from alcoholic 

 specimens preserved at the Department of Agriculture, some of which 

 have been kindly presented to me by Mr. Howard. 



jEggs. — Oval ; one end bluntly rounded, the other conical, slightly 

 flattened above and below. Pure white, very slightly shining, a small, 

 round, yellowish translucent spot in the centre of each flattened side. 

 (The large end is eaten away in all the specimens, by the young larvae, 

 so I am not able to describe the micropylar region.) 



Length i. 8 mm., width i. 5 mm. and 1.4 mm. through the flattened 

 sides. Shell minutely roughened under a half-inch objective, but 

 without marks. Laid in irregular clusters without any covering. 



Stage I. — Head and thoracic feet shining black; cervical shield, 

 leg plates and anal plate, as well as a dorsal patch on joint 13, brown 

 black. Body grayish white with a row of subdorsal segmentary orange 

 spots, diffuse and broad. Warts small, black, each with several hairs, 

 fine, spinulated and rather long. Arrangement of the warts normal 

 (Psyche vii, 259), the secondary warts very feebly developed, obscure; 

 warts iv and v also obscure, vi divided. On the thorax the posterior 

 subdorsal wart (iia) is larger than in Clisiocampa and bears several 

 hairs. No secondary hairs. Width of head 1.05 mm. 



Stage IF. — Head, cervical shield, joints 12 and 13 dorsally, anal 

 plate and anal feet black; width of head 3.0-3.2 mm. Body gray, 

 mottled with black, defined in a series of subdorsal dots and narrow 

 lateral line, between which runs a broad orange-red band. Hair fine,
