232 THE CANADIAN ENTOMOLOGIST. 



(d). — Pale-yellowish, rather stout and quite hairy Larva, with 



BROWNISH STRIPES. 



Length, 10 mm. Ground colour very pale-yellowish or whitish. Five 

 usual pairs of prolegs. Head, prothorax, anal segment and whole ventral 

 surface especially pale. A lateral rather wide stripe on each side encloses 

 the spiracles ; each section of it, corresponding to an abdominal segment 

 (except on anal), marked by the spiracle in the centre, and extended into 

 a sharp prolongation dorsad, ventrad and caudad (especially the first two), 

 bearing a small dark papilla from which springs a long hair ; a similar 

 papilla below the sections bears a similar hair. Dorsum of larva with 

 three pairs of brownish longitudinal lines, a median and two lateral ones. 

 Between these are whitish and pale-brownish lines, the dorsal integument 

 being covered with short, stubby bristles of these colours ; and each seg- 

 ment with two pairs of light, smooth and naked tubercles, each bearing a 

 rather long hair, the anterior pair of tubercles more approximated to each 

 other than the hind pair. The head and prothorax also bear hairs. 



One specimen, swept May 28th, 1891. (No. 228) 

 (e). — Green Larva, with a whitish line along each side of body. 



Length, 14 mm. Venter light. Usual five pairs of prolegs. Whole 

 surface of body, both above and below, evenly and quite thickly clothed 

 with fine, short hairs. Head concolorous, similarly clothed with hairs. 

 Hairs arising each from a small, black, dot-like tubercle, which occupies 

 the centre of a circular naked areole, the rest of the epidermis being 

 covered with microscopic black spines which appear only as closely 

 approximated minute specks under a high power lens. These areoles are 

 particularly distinct on dorsal regions, somewhat less so on sides of 

 venter, the median ventral region and head not showing the microscopic 

 epidermal specks. The dots from which the hairs arise are also absent 

 on median ventral region. The principal segments show five transverse 

 wrinkles or folds above, dividing the dorsum of the segment into six 

 transverse sections ; each section usually bears a row of areoles, though 

 some have additional ones irregularly interspersed, which are usually 

 smaller. These transverse wrinkles stop at the whitish lateral line on 

 each side, which defines the lateral edge of dorsum. 



One specimen, swept May 12, 1891. Colour noted in life. (No. 78.) 

 (/). — Green Larva similar to preceding. 



Length, about 23 mm. This exactly resembles the preceding (e), 

 except in one or two details, which may indicate its distinctness, or may
