mentum, base of mandibles and around the ocelli, which are not easily distin- 

 guished from the more globular of the shagreenations. Cervical shield more 

 glabrous than head, and scarcely darker than the body except around hind 

 border. Thoracic legs very short but stout, with the horny parts deep brown, 

 and sparsely armed with bristles. Prolegs well developed, the hooks in double 

 row and forming a distinct purple-brown, transversely oval annulus, but slightly 

 broken at the narrow ends. A)ial shield rounded behind, coreaceous rather 

 than corneous, and with a slight increase of bristly hairs, especially around 

 border. Stigmata large, with a purple-brown, oval annulus. 



Pupa — Average length 1.50 inches. Cylindrical; broadest at shoulders, the 

 abdomen large, recurving ventrally toward anus, and terminating in a broad, 

 flattened, posteriorly rounded, transverse, slightly decurving flap, the borders 

 thickened basally and extending ventrally so as to surround the bilobed anus. 

 Eyes prominent, with a transverse carina : wing-sheaths reaching hind part of 

 4th abdominal joint, ventrally; hind tarsi to about the hind third of these, and 

 the club of antennae — which forms a prominent bulge but tapers to a point — 

 nearly as far. Surface but slightly polished and faintly corrugate ; a few 

 extremely minute bristle-like spines distributed over the abdominal joints, dor- 

 sally, and the two or three terminal joints with stiff rufous hairs, increasing 

 posteriorly and thickest on the flap. Chitinous covering delicate, and all the 

 members clearly defined. Prothoracic spiracle showing as an opaque, elliptic- 

 ovoid wart. Color brown-black anteriorly, paler on the abdomen, and more or 

 less densely covered with a white powdery secretion like that which character- 

 izes the full-grown larva." 



As regards structural features the claw segment seems to be the 

 same as in the following subspecies ; there is a slight but noticeable 

 difference in the 3 genitalia ; the 9 we have been unable to dissect. 



Genitalia. $ . The Uncus and Penis present nothing whereby 

 they can be separated from the same parts of the following sub- 

 species ; we shall discuss these later. 



The Clasp (PI. V, Fig. 2) is of the same general type as in the 

 preceding members of the family but differs markedly in the minuter 

 details ; the Blade is not drawn out apically to a long hook ; its ventral 

 margin is rather abruptly angled distally, and from the main body of 

 the blade, immediately above the angle, a chitinous ridge extends to 

 the apex of the dorsal margin of the Blade, forming, as it were, the 

 base to a chitinous area which juts out beyond the outer margin of 

 the Blade and is evenly rounded outwardly. The dorsal margin of 

 the blade is dentate, the Proharpe very broad basally. not much bent 

 inwards from the general surface of the clasp, strongly spined out- 

 wardly and apically, almost attaining the dorsal margin of the Lobe; 

 this latter portion is rounded apically and very similar to that of 

 the other members of the family.
