Dr. G. D. H. Carpenter on Acraeine larvae. 708 



ham identified them as Acraea humilis, E. M. Sharpe, and 

 Acraea orestia, Hew., so that these two were shown to be 

 forms of one species. Both larvae and pupae had been so 

 like those of A. alcifqic that no suspicion had crossed my 

 mind that they were of a different species. 



The third instance of resemblance concerns larvae of the 

 genus Planema. On August 17th, in the jungle of Damba 

 Island, about 5 p.m., I saw a female Planema macarista, 

 E. M. Sharpe, sitting on the leaf of a creeper, apparently 

 just completing oviposition. I saw her lay the last egg, 

 and then captured her. The eggs were laid all together on 

 the upper surface of one leaf, but each distinct from the 

 others. They were barrel-shaped, rather elongated, lemon 

 yellow, attached to the leaf in an upright position by one 

 extremity. Under a low power of the microscope the 

 surface was seen to be longitudinally ribbed, with iaintly 

 marked cross bars between adjacent ribs. They were 

 twenty in number. All except one hatched on August 

 25th ; and the dates of the successive ecdyses of the larvae 

 were Aug, 31st, Sept. 7th, Sept. 11th, and Sept. 16th. 

 Unfortunately the majority of them died after this from 

 an infectious disease, but one or two, though dwarfed 

 pupated on Sept. 21st, these pupae subsequently dying. 



The larvae were of a bright, shining, claret colour, with 

 black head, legs and spines, the latter being rather long. 

 Until more than half grown these larvae congregated 

 together in a mass, whereby, under natural conditions, 

 their conspicuousness would of course have been greatly 

 accentuated. Though I obtained no imagines from this 

 brood, the parent was undoubtedly PL macarista. [The 

 parent was exhibited to the Society on Oct. 16th, 1912. — 

 E. B. Poulton.] 



The description of the pupa was as follows : — 



Pinkish white, with black veins on the wings, and small 

 black linear markings on the ventral surface. On the 

 head are two widely separated pointed processes of the 

 same colour as the body. From the dorsal surface of the 

 abdomen project four pairs of long thin black spines, 

 hooked at the tip, arising each from an orange pink 

 tubercle, on each side of the outer aspect of the base of 

 which is a black line ; except the anterior tubercle which 

 has only a short black line anteriorly to its base. 



In October, one of my boys brought me from the Damba 

 jungle on the leaves of a creeper of a different species from
