104 JOHN B. SMITH. 



The larva, according to John LeConte, is found at two periods, — 

 in June and in September, on Viburnum and other shrubs of the 

 Caprifoliacke. We have not a figure of it. It seems to us a near 

 neiglibor of riificaudis of Kirby. 



Mr. Grote says this is probably iiniformis, and I think he is cor- 

 rect.

 Head above, dark green ; palpi prominently scaled, converging to the tips, 

 which prominently exceed the front, blackish above and laterally, beneath with 

 the entire under thoracic surface pale yellowish white; eyes margined below 

 with pure white scales; maxillte well developed, blackish : antennae rather stout 

 and long, tapering to base, serrate outwardly, with a short attenuate terminal 

 booklet. Thorax above bright green, becoming somewhat discolorous, tinged 

 with ochreous posteriorly. Basal segments of the abdomen above pale ochreous ; 

 third and fourth entirely deep red; terminal segments olivaceous, shaded me- 

 dially by patches of the same color; anal segment provided with an ample tuft ; 

 laterally, at base, a few ochreous hairs ; beyond, on each side, the anal hairs are 

 largely black, the longer lateral scales from beneath fringe these black lateral 

 portions of the tuft, which are also somewhat folded towards each other termi- 

 nally; medially the anal tuft is obscure reddish, tipped with black; inferiorly 

 rust red. In the female the anal tuft is narrower, pointed, beneath black, red at 

 base ; above dull reddish tipped with blackish. Abdomen beneath dull ferru- 

 ginous or rusty red. The pre-anal segment shows medially a few white scales; 

 laterally longer, pale ochreous hairs converge inwardly from the margins of the 

 segments. Anterior coxae thickly clothed with pale yellow hair, concolorous 

 with under thoracic surface. Legs slender, finely scaled ; anterior femora, tibiie 

 and tarsi obscure pale ferruginous or red inwardly, outwardly pale yellowish 

 white ; middle femora and tibiae entirely pale whitish, with a dark discoloi-ed 

 dot at the joint above; tarsi ferruginous, paler towards the base. Posterior legs 

 with the femora and tibiae pale yellowi-sh white ; tarsi and base of the tibia' dark 

 ferruginous or red ; tibial spurs rather feeble, pale colored. Anterior wings nar- 

 row, much produced at apices, short along internal margin, dark claret brown 

 covered at base with bright green scales ; discal cell narrow, brought near to the 

 base of the wing, traversed longitudinally by a bar of scales. The costa is nar- 

 rowly covered with ferruginous scales from just beyond base to apex. Centre 

 of the wing taken up by an obliq\ie vitreous space, free from scales, much as in 

 n. thysbe. A terminal brown marginal band narrowing to internal angle, its 

 inner margin sinuous, not dentate on the interspaces. On internal margin, l)elow 

 the vitreous space, a few scattered pale scales. Secondaries smaller, but quite 

 similar to those of H. thysbe in general coloration and appearance ; the vitreous 

 space crossed by six nervures ; under surface resembling upper, dull rusty red. 

 with a few pale scales at extreme base. Expanse 1.65 — 1.80 inches.
