The extended larva is 21 to 23 mm. long, of a nearly white color; 

 head, smaller than first segn.ent of body, somewhat oblong, slightly 

 narrowed anteriorly, brown, with inverted Y mark, and sutures at base of 

 mandibles, white ; at the juncture of the two branches of tl)e Y mark, is 

 a crescent shaped, white space, thickly blotched with brown ; the concave 

 side of this space is downward, and the branches of the Y mark, in a 

 measure, form its outline ; front de[)ressed between branches of Y maik 

 with a narrow, straight dark line, extendmg from their confluence to near 

 frontal suture, lower margin strongly ridged. (3n each side of this dark 

 line are three setigerous depressions, and there are several longer sera; on 

 the sides and vertex. Antennae rudimentary. Just above each ol tlie^e 

 is a setigerous puncture, and again just above these is a smidl semi-irans- 

 lucent spot. Eyes wanting. Mouth parts, light brown ; mandibles 

 darker, stout, concave on inner side, bifid at tip, the lower portion bemg 

 shorter and more cuived, with a small, broad tooth on inner margin. 

 Body, wrinkled, increasing from head to third segment, then decreasing 

 to fifth, sixth to eighth equal, ninth larger, tenth still larger, eleventh 

 smaller, twelfth much smaller, sub-convex and cypeilorm behind, with 

 anal aperture in center of disc. The first ten segments are divided above 

 by two transverse wrinkles, forming two long and one slioit iransver>e 

 folds on each, the latter being placed anteriorly. 'The eleventh segment 

 has but one wriidde, and the twelfth none at all. The first segment is 

 larger than the head, with light brown patch resembling a cervical shieUI, 

 which is dividetl by a median, lineal white line, and, bearing on front 

 and posterior margins, a transverse row ol short bri>tlts. There is also 

 a cluster of four bristles at each end of the cervical shield, and Itetweeii it 

 and the spiracle ; on the second fold are two, small, light brown patches, 

 divided by a dorsal, white line, each patch bearing a sin.i^le l)ri>tle. Tlie 

 second segment has also a transverse row of bristles, and besides there is 

 also one placed singly on each side of a slight, medial depression. Seg- 

 ments three to eighth with similar row of small bristles only, the ninth 

 having a single bristle on each side of the fold near the ndddle of the 

 back. The tenth segment has a row of larger bristles, ami two on each 

 side of fold. On the eleventh, the bristles are still longer, and inclinul 

 to form clusters at the sides, near the s])iracles. On twelfth segment, 

 the bristles form a semi-circular clus er. On each segment, except the 

 second and twelfth, is a double row ol obtuse, \elIowish pustules, 

 placed just below the spiracles, each bearing a few, short, scattering 

 bristles. Between these rows of pustules is a deep, lateral groove, and, 

 where this crosses the segmental wrinkle, a deep, quadrangular fossa 

 is produced. 



Beneath, the feet are wanting, and their place supplied by pust-
