14 Mr. F. Mnir and Dr. D. Sharp on 



minute spot at the liumeral angle pale ; lieliind the middle the dark 

 colour extends outwards again to the margin, leaving a large pallid 

 spot at the side between itself and the anterior outward extension ; 

 near the summit of this spot the surface is rather deeply depressed. 

 The black colour may be so much extended as to nearly obliterate the 

 lateral pallid mark. There is trace of hairs on the surface, which is 

 rough and not shining. The under-surface is vaguely variegate 

 with black ; the colour of the epipleural dilatation being the same as 

 on the upper-surface. 



I am indebted to Hevr Julius Weise for the information 

 that this species is undescribed and allied to C. innotata, 

 Boh. It lives at Durban on a species of Solanum, but has 

 only once been met with, — D. S. 



I have only taken one batch of this species, and the 

 larva and pupa (figs. 25a, 2oh, PI, V.) aie similar to 

 Cassida unimanda, being hidden under a shield of 

 excrement. — F, M. 



7, Cassida linimacula.

This larva is flattish and dark in colour, with the spikes 

 and edge of the body of a lighter colour. The larva is 

 surrounded with spikes as in A. fWMctieosfa, hut the spikes 

 are flattish and edged with spikelets. The ninth abdominal 

 spikes are larger than the others, and shortly after hatching 

 become covered with excrement. At each ecdysis the old 

 skin is retained on the ninth abdominal spikes, and is 

 soon covered over with excrement and forms a triangular 

 shield, which is carried over its back and completely covers 

 the larva, I have often mistaken this larva for the excre- 

 ment of snails, which are very plentiful on its food-plant 

 {Bracliylxna discolor). 



Pupa. The pronotum is greatly enlarged in the pupa, 

 and its edge is surrounded with little spikes, two pairs 

 of which are larger than the rest. All traces of spikes 

 on the meso- and metanotum are lost, and the first five 

 abdominal spikes become thin flat spade-shape membranes, 

 edged with spikelets. 



The system of using the excrement is in this species 

 the same as it is in the European congeners, and is totally 

 different from that adopted by the species of AsjndoniorpJia ;
