feeds on the underside of the leaf, is fully exposed during the daytime, and suffers 

 more from the attacks of ichneumons than the majority of larvae he is acquainted 

 with. Three weeks are passed in the larval stage, and ten clays in the pupal 

 stage of the first brood, the second brood remaining in the pupal stage throughout 

 the winter. 



Ch^rocampa orpheus Herrich-Schaeffer, (Plate VII. figs. 6, larva, side view ; 

 7, larva, dorsal view ; 8, pupa.) 



Chesrocampa orpheus Herricli-Schaeffer, Aussereur. Schmett. fig. 104 (1851). 



Larva. Head olive-brown. Body : first three somites pinkish grey, with a dorsal, 

 two lateral, and two spiracular longitudinal brown streaks ; the upper two broad on 

 3rd somite, and gradually tapering to narrow at the head ; on 4th somite the usual 

 " eye "-like spot, olive-green iris with dark brown pupil, inside which are two minute 

 white spots, with one larger white spot above them situated on the iris ; dorsal area of 

 body rich dark brown, with seven V-shaped pale streaks, olive-green, paling to white 

 in the centre, one on each somite, the apex of the V pointing towards the head ; below 

 this a broad pale lateral line from 5th somite to horn, white superiorly, olive-green 

 below, succeeded by an irregular, narrow, black spiracular line ; ventral area and 

 claspers pinkish grey; horn pale olive-brown ; spiracles greyish. 



Feeds on species of orchid, AnseUia africana (Lincil.). 



'We pupa, which is formed in a hollow of the trunk of the tree on which the orchid 

 is growing, is similar to that of Chcerocampa osiris, but much smaller, and is remarkable 

 for its elongated snout (or haustellum-cover) and the spur-like projection at the apex 

 of the wing-covers. It is usually of a pale shade of olive-green mixed with pale 

 brown and minute black spots (fig. S). 



When the larva is walking the horn moves forwards and backwards. During the 

 daytime the larva generally remains motionless on the brown part of the stem of the 

 food-plant, where its brown colour gives it protection ; in the evening it comes out on 

 to the leaves to feed : when resting the first three somites are retracted some distance 

 into the 4th, and the whole larva bears dorsally what may be described as a striking 

 resemblance to the head and neck of one of the smaller " Avhip "-snakes, or " Kraits," 

 as they are called in India — an analogy which I have before pointed out in the case of 

 the larva of Clmrocampa osiris. The specimen figured was presented to me as a 

 living larva by Mr. A. D. Millar; it pupated on board ship in the tropics on 

 15th April, 1901, and passed about one month as a pupa. 



The moth is found in gardens in Durban, and is considered a rarity.
