hairs on the lower side and on the abdominal legs are dark, almost black; as are those arising 

 from the blue tubercles. The tubercles of the spiracular row are now flesh-colored, not green. 



Thoracic legs pale yellowish brown; abdominal legs green, including part of the anal pair; 

 the plantse are dark flesh in color. The principal change from the preceding stage is in the blue 

 color of the tubercles of the infraspiracular series. 



Stage VI and last: Molted November 3 at 5.30 p. m. Described November 10. Length 

 38-45 mm.; the larva were undersized from being fed on hard, dry oak leaves so late in the 

 season. Directly after hatching the head is pale whitish, with a greenish tint and no spots. 

 The body very soon becomes greenish, and the red lateral band afterwards appears. In a few 

 minutes the hairs on the head and thoracic segments, at first limp and soft, straighten out; 

 those behind on the abdominal are still moist and curled up. At 6 p. m. the front edge of 

 the prothoracic segment had become straw-yellow. All of the suranal plate and the sides of 

 the anal legs are now whitish. The silvery spots are still dim, not yet bright and shining. The 

 thoracic legs are whitish and limp; the abdominal ones green. Three hours and a half later 

 (9 p. m.) the black spots on the head had appeared, being as in the previous stage, but the 

 head was still pale whitish and the legs limp and white. The long white hairs of the abdominal 

 segments are now extended at their full length. At 3 p. ni., November 4, the head and 

 legs had become browner and the larva had begun to feed. 



Head large, nearly as wide as the body, ash-brown; front with eight conspicuous black 

 dots; clypeus-posterior edged with black, with a short black line on each side; also on the 

 side of the head a short dark shade passes up a little way from the ocelli. 



Body cylindrical, the segments convex, somewhat angular, beautifully pea-green in hue. 

 Anal legs large, much as in Telea. The larva differs from that of Telea in the body being 

 provided with long hairs arising from the tubercles, these hairs being distinctly bulbous at 

 the end and dark brown, while there are other pale yellowish hairs arising from near or between 

 the tubercles. One of these flattened (?) hairs arises from in front of each tubercle. The 

 longer hairs are about two-thirds as long as the body is thick. No tubercles on the prothoracic 

 segment, only low flattened vestiges giving origin to fine slender hairs projecting over the 

 head. The silvery spots on the tubercles as bright as in stages IV and V. All the tubercles 

 (except those of the lowest series) of a pale purplish blue; the lowest (infraspiracular) tubercles 

 much deeper turquoise-blue, as in stage V. There are four stout spines on each dorsal tubercle, 

 besides the hairs, as in stage V. The hairs below the spiracular line and on the abdominal 

 legs black. 



There are in this stage four large conspicuous metallic bullate spots on the dorsal region 

 of the first and second abdominal segments and on the sides of abdominal segments 1-3. The 

 battledore-shaped white hairs as in stages IV and V. The lateral reddish and livid line, and 

 the color of the anal legs as described under stage V. The spiracles of the prothoracic and 

 eighth abdominal segments pale sienna-brown; all those between are black with a median 

 pale brown slit. The tubercles hi general as in the previous (fifth) stage. 



The dorsal tubercles of the third thoracic segment a little larger than those before or behind. 

 The median tubercle on the eighth abdominal segment scarcely one-half as large as the dorsal 

 thoracic ones and now showing little signs of the median furrow, though the setae are grouped 

 together on each side, i. e. arranged bilaterally; yet the tubercle seen from above is broader 

 than long. The legs, both thoracic and abdominal, are as described under stage V. 



ANTHERffiA PERNYI ROYLEI (Moore). 



The Indian form or local subspecies of A. pernyi (cf. Hampson). There are 10 specimens 

 in the British Museum, all slightly paler than the China, Amur, and Japanese examples of 

 pernyi. The cocoon of pernyi has a stalk, that of roylei is without (Hampson). A. roylei is 

 from Darjeeling, N. W. Himalayas. 



[Hybrids have been bred; pernyi $ xroylei 9 (hybr. kirbyi Tutt.) and roylei 2 X pernyi 

 9 (hybr. moorei Tutt.). A. pernyi has also been crossed with A yama-mai (hybrids perny-yama 

 Bourd. and inversa Tutt.)].
