Butterflies and skippers of the afrotropical region

“Larva: Pale whitish-green; the spines not rigid, very long, yellowish, set with inconspicuous black bristles. Head yellowish-brown, shining, the base slightly tridentate; mandibles black. Legs of the same colour as the body, longer than usual. Along middle of back, on segments four to eleven, a row of indigo-blue dots arranged in pairs between each subdorsal pair of spines; only one such spot on segments three and twelve. On each side, between subdorsal and lateral rows of spines, a row of larger indigo-blue spots, one on each segment from the second to the eleventh; spiracle, ringed with the same colour; also an indigo-blue sub-spiracular festooned streak. Pupa. Whitish-green. On back of abdomen four pairs of long divergent red spines, set rather widely apart; on each side between each spine and its successor two indigo-blue dots; on back of thorax three pairs of short tubercular processes, each marked with an indigo-blue dot; head with a pair of similar, longer, curved processes. I describe this curious larva and very remarkable pupa from the sketches and notes of Mr. W.D. Gooch, who reared the butterfly in Natal. He observes that one of the caterpillars, in the absence of a proper supply of its food-plant, devoured a chrysalis of its own species.”
