52 ME. R. TRIMEX OX BUTTERFLIES FROM [Jail. 16, 



ii. p. 103, is distinct from L. otacilia, mihi ; and, though larger and 

 darker than Hewitson's figure of the male, may prove on comparison 

 with Hewitson's specimens to belong to the same species. The 

 examples in the Hewitson Collection bore the localities of Sierra 

 Leone and Angola. 



The two males in Mr. Selous's collection were taken at Umtali 

 and in the Mineni A' alley, respectively, on the 28th February and 

 7th March.

1 Mr. A. E. Hunt, lately of Durban and now of Newcastle, Natal, has 

 reared this Butterfly from larvae found in the seed-pods of Crotalaria capensis 

 at Pinetown and near Durban, and has sent me descriptions and drawings of 

 the larva and pupa, from which the following diagnoses are framed. 



Larva. — Above greenish grey, spotted with black (in some specimens a tinge 

 of purplish) ; first and second thoracic segments chrome-yellow, the first bearing 

 a median black mark like a broad arrow reversed, the second with two trans- 

 verse rows of three black spots each ; a transverse row of five black spots on 

 the third thoracic segment and on each of the six following abdominal segments ; 

 spiracles black ; head black ; underside and legs dull yellowish. Last three 

 abdominal segments obliquely flattened and sloping posteriorly, hollowed and 

 wrinkled superiorly. Entire upper surface densely set with short black bristles ; 

 also a lateral edging of short white hairs. Length 7£ lines. 



Pupa. — Thorax and wing-covers dark glossy blackish brown ; abdomen dull 

 reddish yellow thickly sprinkled with black atoms, and with a narrow dorsal 

 median stripe of black ; head reddish yellow above, shining black beneath, with 

 a fringe of fine white hairs along the front. Entire upper surface sprinkled 

 with very short white hairs; under surface smooth and glossy. Humped 

 dorsally, being markedly constricted at junction of thorax and abdomen ; 

 flattened inferiorly. Attached by the tail and by a silken girth. 



It will be seen that the early stages much resemble those of a near congener, 

 D. isoerates (Fabr.), common in India and Ceylon, the larva of which has long 

 been celebrated for its singular habit not only of feeding in the interior of 

 pomegranate, and other fruits but also of finding its way out shortly before the 

 change to pupa and "spinning a strong web over the basal portion of the fruit 

 and over some considerable length of the attaching stem, so that should the 

 fruit be separated from the stem it will not fall to the ground " (de Niceville, 

 Indian Museum Notes, vol. i. no. 4, p. 194, 1890 ; and Butt. India, iii. p. 478, 

 1890). But the larva of D. antalus does not appear to share the very re- 

 markable habit in question (first brought to notice by the late Prof. Westwood 

 as loDg ago as 1835), as Mr. Hunt notes nothing of the kind. He writes, 

 however, that the first pupa found was attached to the inside of a pod of Crota- 

 laria which had a round hole at the tip, while the larvae subsequently found 

 by him were in pods without holes, and in every case left the pod after it had 

 once been opened. He believes the latter course to he traceable to the pod's 

 twisting as it dried and so squeezing the larva. One or two full-grown larva; 

 which were placed in a pod ate their way out and fastened themselves under 

 the nest of a mason-wasp that was in the same box. The pupal state, in June 

 and July, lasted from 18 to 21 days. Mr. Hunt adds that the pupa, on being 

 touched or disturbed, gives a very distinct squeak, although he could not trace 

 any movement of the insect accompnnying it.
