front, flattened along its entire outer side and there clothed with very short 

 adpressed scales, inner side of first and second branch clothed with longish hairs 

 which project downward, which are longest at the base and towards the end, upper 

 outer-edge clothed with a compact crest of forward-projecting hairs which increase 

 in length to end of second joint, where the crest forms a prominent point and sends 

 forth some shorter projecting hairs over the apex, third joint short, slightly decum- 

 bent, pointed in front, clothed with short stout hairy scales ; lower edge of first and 

 base of second joint clothed with longer hairs. Antemice long, slender, very slightly 

 thickened towards the end. Forelegs aborted in both sexes ; fore tarsus very short, 

 scaly, in the male cylindric and pointed, in the female spatular and furnished along 

 the tip with three opposite pairs of short stout spurs, giving it the appear- 

 ance of a miniature mole's foot ; middle and hindlegs long, slender, smoothly 

 clothed above; the tibi^ and tarsi spiny beneath, the former each with two 

 short straight terminal spurs, the latter each with two apical curved claws. 

 Abdomen of male furnished at the apex with four extensible pencils of long 

 hairs, each pencil, in the dried insect,* being exserted from an independent tubular 

 sheath, projecting from the superior lateral apex of the abdomen between the 

 integument and the coriaceous conchiform claspers. 



Larva. — Cylindrical, naked, banded with several transversely alternating 

 conspicuous colours ; furnished with four pairs of long fleshy filamentous processes 

 or tentacula. 



Ty2^e H. Lynceus. 



GeneeaIi Chakactkkistics axd Habits. — " The species of Hestia are remarkable 

 butterflies, of large size and with elongated wings; they are essentially tropical 

 insects. All the known species are from the Indian or Indo-Malayan regions. 

 Within our limits they are confined to the South of the Peninsula and along the 

 Western Ghats to the South Konkan, Ceylon,, Andaman Islands, and Burma. The 

 texture of the wings is extremely delicate, and the colour throughout the group is 

 semi-transparent white or greyish-white, sometimes pure, sometimes slightly 

 powdered with minute blackish scales, and sometimes sullied with smoky-brown, 



* In the dried specimens of the Bornean species H. Lynceus I have been able to find only 

 two of these exserted pencils of hairs, one on each side of apex of the abdomen, but in specimens of 

 K. malaharica, and the Sumatran H. Druryi,! have examples showing two pairs of these exserted 

 pencils, a pair projecting, one above the other, from separate sheaths, on each side of the apex of 

 the abdomen, the upper pencil being the longest. These pencils of hairs are to be seen in the 

 dried specimens only when left exserted at time of the death of the insect, and in most cases it 

 would appear that only the two upper pencils are left exserted, but when the four are protruded 

 they stand out prominently. Mr. Doherty (.Journ. Asiut. Soc. Beugal, 1886, p. 109) also gives 

 four, as the number of these tufts in the male Hestia.
