HETERO PACHA RILEYAXA. 



BY CAROLINE G. SOULE, BROOKLINE, MASS. 



Eggs laid July 1, 1891, at Columbus, Ohio. 



Eggs globular, opaque white mottled with 

 dark green, a dot of green on top. 



July 11, 1.30 P.M., they hatched. 

 Young larvae 1-8 inch long. Head very 

 large, round, horn-colored mottled with 

 brown. Body gray, striped longitudinally 

 with dark brown on each side of the dorsum, 

 nth segment black on top. Body covered 

 with short, gray hairs. Feet and props 

 gray. Anal props very slender and spread 

 far apart. The body tapered from head to 

 anal end. The larvae moved very fast, and 

 were flat instead of cylindrical. 



Three days later they had changed some- 

 what in color, the head being dull white 

 barred with brown ; the body dull white on 

 dorsum with a black dorsal line, and a black 

 dash on each side of this line. From each 

 dash arose a small, dark wart with short 

 spreading hairs. The sides were dark gray 

 with a dull white line from 5th segment to 

 anal props. The hairs were most abundant 

 over the head and feet, and were grayish. 

 Each segment had a few warts, with sparse 

 short hairs. 



Jul}' 16. First moult. Head darker, hairy, 

 mottled with white, the dark and -white lines 

 extending back over the first segment, the 

 body, as before, giving the effect of black and 

 white stripes. The tapering from head to 



anus was very noticeable, as was the flat, 

 leech-like shape. The hairs were long over 

 the feet, shorter along the stigmatal line, and 

 very short on the sides and dorsum. 



July 19. Second moult. Length 1-2 inch. 

 Head dark barred with white hairs. Bodj' 

 tan-colored on dorsum with two black dashes 

 on each segment. Lateral and stigmatal 

 lines, nearly black. A black patch on top of 

 the nth segment. Feet and props dark 

 gray. Hairs sparse and short except over 

 feet and props, where they seemed to "fringe" 

 the whole edge of the larva. 



July 23. Third moult. Length one inch 

 or a trifle less. Head black with two short 

 yellow lines on top, and a yellow spot near 

 the mouth, hairy. Body brown on dorsum, 

 yellow between the segments, with black 

 dashes. Two yellow dashes on 12th segment. 

 No black patch on nth segment. Lateral 

 and stigmatal lines of black and pale brown. 

 Feet and props dark, overhung by long gray 

 hairs in tufts. Very short hairs on the dor- 

 sum, and very sparse. 



July 27th. Fourth moult. 1 1-2 inches 

 long. Head as .before. The body was 

 marked with brown, black, tan, and yellow 

 or white, in a sort of "oil-cloth pattern" very 

 difficult to describe, and varying with indi- 

 viduals. The dorsal hairs were unnoticeable 

 without a lens, but the stigmatal fringe
