332 REPORT OF THE COMMISSIONER OF AGRICULTURE. 



'The larvae of the i)reseiit species were found at Providence, E. I., feed- 

 inj? upon the young, freshly unfolded leaves of the white-heart hickory 

 (Carya tomcntosa), rolling them up. Within the roll the chrysalis was 

 discovered from June 2 to 4. The iusect remains about two weeks in 

 this stage, the moths appearing in my breeding-box June 17 and 23. 



The moth belongs to that section of the genus with moderately wide 

 fore wings, which are oblong, and moderately pointed at the tip. Pro- 

 fessor.Fernald informs me that it is allied to Gelcehia bicostomaculclla of 

 Chambers. 



Descriptive. — AToili. — Palpi very long, tlie third joint slender, ono-lialf as long as 

 the second; second joint Trith black specks ; third black, but white at the tip. TLo 

 fore wings broad, oblong. Head, thorax, and wings blackish, with whitish buif-yel- 

 low si^ecks and dots. The fore wings are dark pepper and salt, with a row of live 

 deep black spots along the middle of the wing, increasing in size towards the end of 

 the wing; the bas.al spotmimite; the third large, and sending a branch obliquely 

 inwards to the costa ; the fourth ijatch large, irregularly squarish ; above it is a 

 black square costal spot, next to a buif-white, distinct costal si)ot opposite another ou 

 the inner edge of the wing ; the two spots are sometimes almost connected by a light 

 lino. The edge of the wing buff- white with black scales. Ilind wings and abdomen 

 BJato-colored. Length of foro wing, 7'"™; width, LG'""" ; expanse of wings, about 

 15°>°' (O.GO inch). 



TIIE WILLOW TERAS. 



{Teras mburnana Clemens.) 



The caterpillar of this common species is of the ordinary shape and 

 green in color, occurring on the willow in Maine during August. The 

 specimen we reared changed to a chrysalis August 19, remained in that 

 condition a little over two weeks, namely, until September 7. The moth 

 has been determined by Professor Fernald. 



Descriptive. — Larva. — Greenish. 



P«^«.— Body slender ; end of the abdomen flattened and excavated, with two large 

 lateral hooks before the tip. Length, 8™™. 



Moth.— Head, thorax and fore wings rust-red. Head above and front of thorax 

 deep rust-red, hinder edge of the thorax bright red. Fore wings rust-red, deeper on 

 the costa ; a dusky patch at the base ; beyond, on the inner third of the costa, is a 

 broad, paler, square spot, succeeded by a long, dark, deep reddish-brown patch, 

 which extends to near the apex. The rest of the wing is clearer and paler, ash-col- 

 ored, mixed with brick-red scales. In the middle of the wing on the inner third are 

 two distinct, twin, flne black dots. Beyond are three black dots, forming an oblique 

 line, extending from the median vein to a little beyond the middle of the hinder edge 

 of the wing ; a few scattered, black, fine dots near the outer edge of the wing. 

 Fringe broad, reddish externally, dark on the basal half, and grayish on the inner 

 angle of the wing ; hind wings uniformly gray slate-colored ; abdomen dark brown, 

 paler at the tip. Expanse of wings, 18™'" (0.70 inch). 



THE PURPLE WILLOW GRACILARIA. 



( Oracilaria jpurpuriella Chambers.) 



Late in August (the 20th) we found the caterpillar of this beautiful 

 moth, which had turned over obliquely tlie tip of the willow leaf and 

 securely fastened it to tlio under side of the leaf, thus making a trian- 

 gular fold. The worm had eaten the parenchyma from the under (i. e., 

 inner) side, leaving a mass of black castings. The worm soon trans- 

 formed, remaining about two weeks in the pupa state, and the moth 

 appeared September 19. The moth is a very beautiful creature, with 

 a delicate body, wings, and legs. Our example was perfect, and agreed 

 in all respects with Mr. Chambers' description, which is copied below.
