3^^ Mr. Forsayeth on the life-history of 



The pectoral legs are very small. There are one pair of 

 prolegs apparently on each segment posterior to the 

 pectoral legs ; the anal legs are not well marked. The 

 prolegs are membranous and very difficult to distinguish, 

 the movements being snail-like or vermiform, by waves. 

 The head is under a hood formed by the 1st segment, 

 and is not visible even when the larva is feeding ; it 

 can, however, be protruded voluntarily by the larva. 



The pupa is formed in a small oval, very dense, shell- 

 like cocoon (PI. XIV., fig. 8 c) near surface of ground, 

 or on under side of leaves in some few instances. Those 

 made in confinement were always attached by base to 

 wooden floor of the cage, and covered over with sand 

 or earth from one to two inches in depth. The shape 

 of the pupa is peculiar, the body being curved, and 

 wing-cases extending almost to the extremity of the 

 abdomen. (PL XIV., fig. 8 a). 



The larva is figured at PI. XIV., fig. 8, and one of the 

 eight large dorsal spined arms magnified at fig. 8 h.

 Mhow, August 16th, 1879. 



Larva not common. Found on "Palas" {Butea 

 frondosa), on date-palm, and on a shrub which I am 

 unable to name. Habits similar to those of M. albi- 

 puncta. Head under a hood formed by 1st segment. 

 The spines possess the property of irritating the human 

 skin, and the movements and anatomical characteristics 

 of prolegs are the same as in the species above men- 

 tioned. The largest larva I obtained was If in. long, 

 nine chrome-yellow spiracles, and ten lilac spots along 

 each side ; the same number of spots along centre line 

 of dorsum. There are four rows of flesh}^ spines, armed 

 with poisonous hairs on dorsum and lateral margins. 

 Stinging powers severe. The membranous prolegs are 

 best seen when the larva is forced to crawl along an 

 edge, such as that of a card or a paper-knife ; the pro- 

 legs are then tolerably defined as they grasp the edge at 

 each side to keep the larva from toppling over. 



The cocoons are similar to those of Miresa alhipuncta, 

 and are made under the surface of the ground. The 

 LirvaB are infested by a large dipterous parasite some- 

 what like, but larger than, the common house-fly.
