Leindoptera observed in Mhow. 401 



trace of maxillae. The labial palpi were 3-jointed, 

 middle largest, terminal very small. The legs were 

 feathered. No spines on anterior tibiae ; two spines at 

 extremity of middle tibiae ; two spines at centre, and 

 also at extremity of the posterior tibiae. In the male, 

 mouth and legs same as in female, except that the 

 anterior tibia; are furnished with a thick tuft of hair, in 

 which is concealed a strong, jointed, ensiform spine.

 Mhow, September 6th, 1881. 



Found two of these curious larvae on a Babul 

 (Acacia sp.) tree. Legs 6, 8, 2. General ground colour 

 bluish grey. A double line of red dots (tubercula) 

 studded with hairs exist along each side of body. On 

 the dorsum a broad black line runs frofii the brush-like 

 thoracic plumes to the base of the caudal plume. On 

 the dorsal surface of the two segments immediately 

 preceding the caudal plume are two tubercles of a red 

 colour, and without hairs. The head is adorned by 

 two long plumes of black hairs ; a similar plume, but 

 consisting of hairs of three different lengths, ornaments 

 the last segment ; the pennate extremities of these hairs 

 are very singular and elegant. On each side of the 

 thoracic segments is a short plume of similarly feathered 

 black hairs, mixed with longer simple white hairs. On 

 the dorsum of thorax and of 1st abdominal segment are 

 four thick shaving-brush-like tufts of vertical short 

 white hairs ; the three thoracic are separated by a short 

 interval from the fourth tuft. 



Sept. 7th. Both larvae spun small hammocks or 

 cocoons of whitish silk mixed with the hairs off their 

 bodies, and having an opening at one end for escape of 

 the imago, similar to those of Psalis securis. The larva 

 skin remains in cocoon at one end. Pupa : Front clear 

 milky white colour ; back marked with brown. It is 

 attached by caudal point to cocoon. Very fine hairs 

 sparsely scattered on body. 



Sept. 16th. One imago out this morning. In posture 

 and general appearance resembles P, securis.
