scales laterally on second and third segments. Occiput clothed dorsally with 

 flat metallic blue scales, the eye margins and lateral portions of occiput with 

 flat, silver to golden-yellow scales. Thorax: Anterior pronotal lobe covered with 

 broad flat scales, those on dorsal portion brilliant metallic blue. Integument of 

 scutum dark brown, with a narrow median longitudinal stripe and sides primar- 

 ily gold scaled, and with blue reflections when viewed from certain angles; a 

 broad longitudinal submedian stripe of fine dark purplish-brown scales present 

 on either side between the median stripe and lateral pale-scaled areas. Pleurae 

 and coxae shingled with flat golden-yellow scales. Abdomen: Abdomen primar- 

 ily covered dorsally with metallic blue-green scales, laterally with golden- 

 yellow scales. Legs: Femora golden yellow on inner surfaces; tibiae primarily 

 clothed with dark purple scales; fore- and mid-tarsi with ape.x of segment 1 

 and all of segments 2, 3 and 4 white; hind-tarsus with apex of segment 3, all 

 of segment 4 and all but tip of segment 5 white. Whig: Scales rather broad, 

 dark purple, sparse. 



ADULT MALE. — Coloration similar to that of female but the fore- and mid- 

 tarsi with all segments dark purple, the hind-tarsus with the fourth and occa- 

 sionally the base or all of the fifth segment white. TERMINALLA (Fig. 43). 

 Ninth tergite (IX-T) a strongly convex band extending considerably dorsad 

 of underlying structures; lobes (IXT-L) apico-lateral in position, poorly 

 defined and broadly connected, each bearing numerous strong setae. Tenth 

 sternite (X-S) prominent, heavily sclerotized apically. Phallosome (Ph) 

 bottle-shaped, consisting of two separate lateral plates connected only sub- 

 basally on the dorsum by a narrow sclerotized bridge; apical neck-like portion 

 slender, nearly as long as broadened base, heavily sclerotized, pointed, with a 

 bilateral row of short teeth directed ventrally. Claspette absent. Basistyle (Bs) 

 conical, a little more than twice as long as basal width, clothed with scales and 

 long setae; basal lobe (B-L) prominent, rounded, bearing three or four large 

 spines and several smaller ones; apical lobe absent. Dististyle (Ds) nearly as 

 long as basistyle, slender, sides nearly parallel, rounded apically; claw (Ds-C) 

 slender, inserted a little before apex. 



LARVA. (Fig. 44). — Large larva. Head quadrate, about as long as broad. 

 Antenna smooth, about one-third as long as the head; antennal tuft short, 

 multiple, inserted at outer fourth of shaft, preceded by a pair of single hairs 

 at outer third. Mouth brushes consisting of about ten stout, closely appressed, 

 prehensile, smooth, curved rods. Head hairs: Preantennal (A), lower (B), 

 and upper (C) single and of about equal length; postclypeal (d) short, mul- 

 tiple; (hairs A, B, C, and d arranged more or less in a row on the antero- 

 lateral region of the clypeus); sutural (e) absent; trans-sutural (f) and supra- 

 orbital branched beyond bases. Abdomen with numerous stout, barbed hairs 

 arising from sclerotized bases. Eighth abdominal segment without comb, but 

 with a large sclerotized lateral plate bearing two long barbed hairs and two 

 shorter weak hairs distally branched. Siphon one and one-half to two times as 

 long as basal width; pecten absent; subventral tuft multiple, barbed, inserted 

 near base of siphon. Anal segment about as long as wide; completely ringed 

 by the dorsal plate; postero-lateral margin of dorsal plate fringed with a row
