262 THE ENTOMOLOGIST. 



4th, and 5tli are amber-yellow, excepting the sub-spiracular, 

 which are white ; all the other spines on the body are white, 

 excepting the super-spiracular series, which are tinged with 

 ochreous ; all the spines are branched, each branch or spinelet 

 is tipped with amber, and each spine also emits a number of very 

 fine white hairs ; the 1st segment is without spines, but has a 

 transverse series of short and slender orange tubercles, each 

 terminating by a fine pale hair curving forwards ; the head in 

 front is flattened and square, the lobes of the crown are swollen, 

 and each surmounted by a short club-like knob directed forwards 

 and outwards ; upon the clubbed apex are five or six minute 

 orange spines, each bearing a long fine amber-coloured hair ; 

 other similar spines are dotted over the face, the ground colour 

 of the head is dull black, with a pale ochreous central A-shaped 

 mark, and a short orange streak in front on each lobe of the 

 crown. The ground colour of the body is black, reticulated with 

 lilac-grey ; the anterior half of the body is transversely ringed 

 with amber-yellow at the segmental divisions, and those on the 

 posterior half are white dorsally and yellow laterally ; the greater 

 part of the dorsal surface of the 2nd, 3rd, 4th, and 5th segments 

 IS amber-yellow ; from the 6th to 10th segments inclusive have 

 almost the whole of the dorsal surface white, with a short oblique 

 black mark in front of each sub-dorsal spine, also a smaller 

 black spot in front of the medio-dorsal spines, and a fainter one 

 behind ; the white surrounds the sub-dorsal spines, and is bor- 

 dered below by velvety black, then by a rich deep orange wavy 

 longitudinal super-spiracular band, and a similar but paler 

 orange sub-spiracular band, both being united by an oblique 

 narrow streak of deep orange, passing immediately behind the 

 spiracles ; on these bands are placed the spines ; a short straw- 

 yellow streak occurs anterior to and just above the claspers ; at 

 the base of each clasper is a row of four or five small orange 

 warts, each bearing a fine white hair ; the body has several 

 minute warts sprinkled over the surface, each emitting a delicate 

 white hair ; the legs are shining black ; the claspers grey at the 

 base, shining black in the middle, with pale ochreous extremities. 

 When about to suspend itself for pupation the white of the dorsal 

 surface changes to a greyish hue. 



The larvsD are gregarious, living generally in small companies, 

 but sometimes many will crowd upon a certain leaf ; their habits 

 are similar in all stages, the usual resting attitude resembling 

 the form of a fish-hook. The larva suspended itself for pupation 

 on June 20th, and pupated the following day, the larval state 

 lasting forty-seven days.
