CHCEKOC AMPINS. 397 



Hab. S. India and Ceylon. We have bred this subspecies 

 in one locality in S. India, at an elevation of about 4,000 feet 

 on an isolated hill. The larva and pupa closely resembled 

 those of n. nycteris, and separate descriptions were not made. 



Habits. — Similar to those of nycteris. Food-plant : Rubia 

 cordifolia Linn., family Rubia ceae. 



Subfamily CHGEROCAMPINiE Butler. 



Butler, 1877 A, p. 516, 544 ; Roths. & Jord., 1903, p. 672 ; id., 1907, 

 p. 122. 



Imago. — " $3. Pilifer consisting of an apical part bearing 

 short (or vestigial) bristles and a proximal part bearing 

 long ones. Genal process short, not much projecting. Inner 

 surface of second segment of palpus more or less naked. 

 End- segment of antenna elongate, but not filiform, with 

 six or more very long bristles " (Roths. & Jord., 1903, p. 672). 



The pilifer does not vary much within the subfamily, while 

 the palpus exhibits various modifications in structure which 

 are of generic value. Antennae more or less clubbed, especially 

 in the $$, with an abrupt hook, or setiform with a slender 

 gradual hook ; end-segment never very short, shortest in 

 Celerio. They are always different in the sexes ; they are 

 never dentate or pectinate. Eye lashed or not. Tongue 

 always functional, never much reduced, often twice the 

 length of the body. 



Abdomen conical in all forms, generally long and ending 

 in a simple pointed tuft with a rudimentary tuft on each side ; 

 spines multiseriate ; seventh sternite without spines, obtusely 

 triangular, membranaceous at end. Sexual armature simple ; 

 friction-scales always present, generally large and few in 

 number. Scent-organ of fore coxa more or less distinct. 

 Tibiae never spinose. Mid- tibial spurs unequal in length 

 (except in Cechenena), the outer one the shorter. Hind tibia 

 always with two pairs of spurs. Paronychium always with 

 two pairs of lobes, but pul villus without pad in some species 

 (Celerio euphorbias, etc.). 



The moths are mostly large or of medium size ; fore wing 

 brownish or green, with one or more fines running from about 

 the middle of the inner margin to the apex ; hind wing dusky 

 or red with dark base. 



Egg. — Broadly ovoid or nearly spherical, surface smooth 

 and shining, colour green or yellowish. 



Larva. — -Head small and round or semi-elliptical, body 

 tapering more or less sharply from segment 5 irontad, and 

 slightly backwards ; horn very variable in length and shape. 

 Surface usually smooth and dull, but sometimes shining
