156 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Pupa. — Moderately stout; end of abdomen obtuse. The cremaster deeply cleft, 

 each spiue well developed, rather long, not much flattened, ending in a point and 

 throwing off near the end a short branch which nearly meets its fellow with opposite 

 spine. Lengtii 2l'"'i'. 



Moth. — Head gray, vertical tuft above black. Thoi'ax reddish-brown, patagia 

 blackish above. No distinct line on the prothorax. Primaries reddish-brown, ner- 

 vules black. Base of the costa dark, beyond cinereous with brown scales along the 

 edge, which become indistinct waved lines continued across the wing and are more 

 oblique beyond the discal dot. The linear reddish discal dot is surrounded by gray, 

 and below and beyond is a dark rather broad discoloration curved around it. Beyond 

 this the black nervules are interrupted by gray scales. There are two obscure series 

 of reddish dots near the margin in the interspaces. Opposite the outer series of these 

 spots the fringe, otherwise ferruginous, is of a dirty-white. Secondaries white, dis- 

 colortnl with smoky at inner angle. The large tuft beneath the head is lilac-ashen. 

 Beneath, the fore-wings are white, smoky in the middle. Costo-apical dots distinct. 

 Fringe white, black at the ends of the nervules, at the base are white dots in the 

 interspace. Secondaries entirely white, except the dusky spot on the inner angle. 

 Legs ashen, ends of the scales dark, tarsi broadly annulated with dark. Abdomen 

 slender, whitish, a narrow mesial line beneath. In the female the markings are 

 more distinct. The two series of ferruginous waved lines on each side of the median 

 region are more distinct. The submarginal ferruginous region is more broken up by 

 ashen scales. The secondaries and abdomen above smoky. There are faint traces of 

 a slight mesial fascia across the wing. Beneath, both wings are dark smoky. Alight 

 ferruginous line on the abdomen, which is itself larger than in the other species. 

 Length of body, male, 90; female, 95; expanse of wings, male, 1.60; female, 1.80 inch. 



Coelodasys cinereofrons Pack., as stated by Grote, is undoubtedly 

 a variety of this species now to be referred to the genus ScMzura. The 

 following notes on the larva of this variety have been received from 

 Professor Riley: 



June 20, found on oak two very small larvie which entered the ground July 8 and 

 emerged as moths July 30. Color of larva as follows : Second and third segments grass 

 green ; the horn of the fourth segment is two-forked and the tips blood red, also the 

 tips of the two smaller horns on joints 8 and 11. The rest of the body and head, red- 

 dish brown. (Unpublished notes.) 



214. Hyparpax aurora (Abbot and Smith). 

 Larva, Plate III, fig. 6, 6o. 



"The caterpillar was taken on the timber white oak, but feeds also 

 on other species of oak. It went into the ground and inclosed itself in 

 a thin case of dirt July 15, appearing on the wing August 7. Some- 

 times this species also buries itself in autumn, and remains till the 

 spring, at which season the moth may now and then be observed sit- 

 ting on the oak branches." (Abbot and Smith.) 



In New England it is single brooded. The caterpillar, according to 

 Abbot and Smith's figure, has a double red hump on the first abdominal 

 segment, with a very broad dorsal green band between this and the 

 tubercle on the eighth segment; the anal legs are elevated much as 

 in Schizura unicornis. The moth has broad yellow fore- wings, in the 

 female pink at base and on the outer margin. 



I am indebted to Miss E. L. Morton for the colored sketches of this 

 rather rare larva.
