DESCRIPTIONS OF NEW SPECIES AND VARIETIES. 81 



specimens also, a narrow pale transverse line outside the second band, and a pale ter- 

 minal shade, are visible. Hind wings uniformly paler gray. Under surface glossy 

 gray, with no marks, the front wings a shade darker than the hind. $ differs from 

 9 in the basal portion of the auteuiue being 1 curved, and the curve filled with a tuft 

 of scales. 



Described from numerous bred specimens. The species has the general facies of the 

 European Cryptoblabes bislriga, which is a larger insect. 



Larva. Length 0.45 0.50 inch [ = 11 12.5 mm ]. General color olive, or pale green, 

 or brown, with a broad dark stripe along each side of back. Tapers slightly both 

 ways, joints 4-12 inclusive, divided into two transverse folds. Freckled with numer- 

 ous pale specks and with piliferous spots, the specks often taking the form of two pale 

 broken lines along the upper edge of dark stripe. The piliferous spots are pale with a 

 central black dot, and are best seen in the dark specimens. On joints 4-12 inclusive 

 they are placed 4 in a square on the middle of the back, and four more each side, the 

 two upper lateral ones being on the anterior fold, the stigmata appearing as minute 

 rufous specks between them. Both these spots are often double. The third lateral 

 spot is on the posterior fold and the fourth is subventral and anterior. The hairs pro- 

 ceeding from these spots are long and setaceous. Head horizontal, freckled, pale be- 

 hind, tinged with green in front and with a few long hairs. Joint 1 also freckled 

 and with a large black piliferous tubercle with a pale basal auuulatiou and in range 

 with middle of dark stripe. Joint 2 with similar black tubercles with a white centre 

 and replacing the uppermost lateral pale spot. There are but two of the small pale 

 dorsal piliferous spots on this joint (between the tubercles) as well as on joint 3. Be- 

 neath immaculate, except that the thoracic legs have sometimes a few dusky dots. 



In the very dark specimens the head, cervical shield and anal plate remain pale. 

 The cervical shield is then well defined with four small piliferous specks at anterior 

 edge, and the large shiny tubercle forms the extreme anterior angle. 



Described from numerous specimens. 



Pupa. 0.24 inch [ = G mm ] long ; rather stout and short, with two minute diverging 

 spines and a few stiff" bristles at tip. 



In many specimens the stibdorsal dark stripe is obsolete or sub-obsolete, but even 

 then the four black tubercles on joints 1 and 2 characterize the larva sufficiently.

TORTRIX RILEYANA, Grote Larva Length, Hickory feeding, O.GO-0.80 inch [^ 

 15 20 mm ] ; Snowberry feeding, 0.40-0.50 inch [=10 12.5 mm ]. Largest on segment 2, 

 tapering thence gradually to anus. Ground color dull yellow. Covered with large, 

 distinct, black, sealing-wax-like, slightly elevated spots, each giving rise to several 

 fine bristles. These spots are thus arranged on each segment: 2 each side of dorsum 

 the posterior ones widest apart ; 1 at sides in the middle of the segment, containing 

 the stigmata iu its lower hind margin ; 1 smaller and narrower just below this, on a 

 somewhat elevated longitudinal ridge, and 1 round one below this ridge on the pos- 

 terior part of the segment. Segments 2 and 3 have but one spot each side of dorsum. 

 Two distinct wrinkles on all the segments, more on 2 and '3. Head, cervical shield, 

 and caudal plate black. Venter dirty yellow with black marks; legs ditto. 



Chrysalis Honey-yellow, robust in the middle, and with two transverse rows of 

 minute teeth across the back of each segment. 



Perfect Insect From Hickory Average expanse 1 inch, length of body, 0.35 [ =8.8 min ]. 

 Deep ochreous. Fore wings evenly washed with purplish, leaving the fringes and 

 costal edge dark ochreous. The markings take the shape of dark velvety brown 

 rounded maculations, generally of small size and faintly shaded with ochreons on the 

 edges. Three of these subtermiually at the base of the wing, subequal, situated in- 

 terspaceally between the nervures. At a little within the middle of the costa are two 

 fused maculatious, the most prominent. Before and beyond these, some faint costal 

 marks. AtVthe extremity of the discal cell, above median nervure, is the first of a
