Larva. " The larva? of A. caphusa are gregarious, and to pupate 

 burrow under the dry leaves at the foot of their food-plant, the 

 pupae being also gregarious. The larvae spin a joint web, and lie 

 together in communities of ten or more. They feed at night only. 

 Colour when full-grown dirty brown, head black, each segment 

 with a dorsal longitudinal dark brown stripe ; the larva is thinly 

 covered with weak white hairs. Just before pupation the colour 

 turns to a light green, with the head and stripes as before." 

 (Mackinnon.) 



Pupa. " Very similar in shape to that of A. soracte, is greenish- 

 yellow with black markings." (Mackinnon.} 



Food-plant of larva. " Berberis nepalensis, Spring." (de Nice-

Var. pJiryxe, Boisduval. This is the palest of the series of the 

 varieties of ayathon. The intercellular and interspacial greenish- 

 white streaks and spots, which, in var. caphma, are considerably 

 longer and broader and, so far as the markings in the interspaces 

 are concerned, show a tendency to coalesce, in pliryxe become 

 very broad and white, so that the discal series of short streaks on 

 both wings extend to and coalesce completely with the much 

 broadened spots of the subterminal series. In fact, the insect 

 may be described as white both on the upper and under sides, 

 the veins broadly bordered with black, and with black terminal 

 margins formed by the expansion and coalescence of the black at 

 the apices of the veins ; discoidal cell of the fore wing with a 

 large patch of black at the apex. The black along the veins of 

 both fore and hind wing suddenly broadened on the discal area ; 

 on the underside of the hind wing they almost form a connected 

 discal, transverse black band ; the chrome-yellow spot on the 

 precostal area as in agatlion. Antennae black, head and thorax 

 dusky grey, abdomen white ; beneath : head and thorax blackish, 

 abdomen white.

" c? . Upperside : both wings black. Fore wing with a thin white 

 streak at the base of the costa ; a large creamy- white patch 

 occupying the basal three -fourths of the discoidal cell, its outer 

 end produced to a point ; a large patch occupying the basal two- 

 thirds of the iuterno-median interspace (interspace 1), a discal 

 series of five more or less oval spots curving evenly round the 

 outer end of the cell, of which the anterior one is rather elongated 

 and narrow, the three following are equal-sized elongated ovals,
