1917.] 35 



The larvae when uewly hatched are eutirely of an orange colour, 

 with red eyes and a red patch on the dorsum of the abdomen. After 

 about au hour the colou)* changes to pale brown on the fore parts, 

 with three similarly coloured bars in the region of the scent-glands, 

 and spots on the conuexivum. Ultimately the fore-parts, the abdom- 

 inal bars, and the connexival spots become black, and the abdomen 

 may reniain more or less orange, or deepen into crimson, while the 

 legs and antennae become dark piceous, the eyes still remaining red. 

 The antennae are four- join ted, with the terminal joint much the 

 largest, and the first and third sub-equal and the smallest ; the tibiae 

 are strongly ridged, the tarsi are two-jointed, with the terminal joint 

 much the longer ; the claws ai'e strongly curved, and pale in colour. 

 The central lobe of the head projects considerably beyond the side- 

 lobes. The head and thoi'acic segments are shining and almost im- 

 punctate, but with fine transverse striae ; the first two thoracic seg- 

 ments are sub-equal in length and the third is shorter. 



Mr. T. Edmonds, of Totnes, kindly sent me several batches of 

 eggs on May 20th, 1916. One of these batches began to hatch out on 

 June 3rd, and most of the batch emerged on the same day, the greater 

 number of them at exactly the same time. They emerge with the 

 dorsal surface uppermost, and the legs are drawn out last of alL They 

 were fed on furze, but the weather was veiy cold at the time and their 

 growth was correspondingly slow. The first ecdysis did not take place 

 till June 18th, and during the whole of the fortnight of their free 

 existence they had persisted in clustering together in a corner of the 

 box in which they were kept, and quite away from the food-plant ; 

 they would remain in this position foi* days together, quite inactive. 

 At first they were very reluctant to leave the empty egg-shells, cluster- 

 ing on top of them for hours at a time, without moving, and not 

 attempting to reach the fresh food-plant which was close by. 



In the second instar the colours and general form were pretty 

 much the same, save that the antennae were darker, almost black, but 

 the base and apex of the second and third joints had a pinkish tinge, 

 as also the apex of the first and the base of the fourth. The whole 

 insect had now become strongly and densely punctate, and the punc- 

 tures on the red part of the abdomen, being black, were very con- 

 spicuous. The fore-parts still retained some transverse striations, and 

 a small patch on the vertex was alutaceous. The head was still very 

 large in proportion to the body, and the pronotum had become rather 

 Ioniser than the mesonotum.
