790 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



common species feeds on the clover, Vitis, Ranunculus acris, and is an 

 inquiline in willow galls. Forbes has found it to be destructive to corn. 



Larva. — Body tapering towards each eud. The head is honey-yellow, considerably 

 narrower than the body. The body is pale livid green with a corneous hue. There are 

 no lines or any distinctive markings, except the four usual -warts or small tubercles 

 which are arranged as usual in this family in a trapezoid. From these -warts arise 

 hairs one-half as long as the body is thick. At the end of the snpra-anal plate is a 

 flattened tubercle with spines. Length 15™'". 



Pupa. — Length 8™'". Color, dark shining brown, lighter at the eud of the wing- 

 covers and the parts covering the palpi and base of the autenu;«. Front rounded 

 and smooth. Abdominal segments on the dorsal side armed with two transverse 

 rows of small spines inclined backward, those on the posterior edge of each segment 

 finer and closer than those of the other row. Abdomen terminated by a protu- 

 berance, flattened above, rounded at the end, hollowed out underneath the base, 

 and armed with two fiue hooks on each side, and four from the end. (Comstock, 

 Rep., 1881). 



Molh. — This insect may be described in general terms as a brownish yellow moth, 

 the fore wings of which are marked by two V-shaped brown bands (the apex of the 

 angle pointing backwards), so placed that when the wings are closed these markings 

 form an X. 



The palpi are long, nearly or quite twice the length of the head, yellow above, 

 deep red laterally and beneath. The antennae are reddish brown; the head and 

 thorax are yellow above, tinged with red or purple at the sides ; the patagia red in 

 front, yellow beyond. Anterior wings golden yellow, finely reticulated with red or 

 purplish (sometimes the reticulations are wanting), costa tinged with purple at base. 

 A purple spot on the middle of the internal margin throws out two diverging lines, one 

 of which attains the costa at the basal third, the other ending just below a similarly 

 colored subapical costal spot. The internal margins more or less tinged with purple, 

 somewhat constant, and deepest towards the base ; fringes yellow. Posterior wings 

 above and beneath varying from pale yellowish fuscous to dark fuscous or blackish. 

 Under surface of anterior wings clouded centrally -with fuscous; the mai'gins paler, 

 sometimes yellow. Abdomen brownish, legs pale silvery brown, anterior ones dark- 

 est. Expanse, female, 14 to 17"™; female, 17 to 19""". (Forbes.) 



123. Teras ferrugana S. V. 



The larva was beaten from the white pine (P. strobi) at Providence, 

 October 5. 



Larva. — The body is rather large, 20™"" in length, broad and flat. Head flattened, 

 held out horizontally, reddish above, -with a dark broad line around the edge. The 

 body is green, with a reddish tint. The cervical shield is concolorous with the body, 

 and edged behind with dark black-brown, forming a curved line. Over the body 

 above are scattered pale flecks. 



The caterpillar pupated in the bottom of the breeding-box without 

 making any cocoon. 



Pupa — Slender, 7 to 8'"'" in length, of the usual pale horn-brown color. Each ab- 

 dominal segment is provided with two dorsal transverse rows of close-set spines. 



The tip of the abdomen is suddenly truncated, compressed from above downwards, 

 the edge is hollowed within, the edge itself curvilinear, with a small spine on each 

 side. It differs from that of T. viburnana in the end being broad, square, and flat- 

 tened vertically, while the hooks are almost obsolete. 



The moth appeared October 20 or 21. I am indebted to Prof. 0. H. 

 Fernald for kindly identifying it. According to his Catalogue of Tor-
