eggs and are then about 1 [ s inch long with a large, straight caudal horn 

 pointing obliquely up and backward. After the first molt the seven oblique

 series of reddish spots along the longitudinal whitish stripe. 



Apatelodes torrefacta Abb. & Sm. 



A pretty yellowish or whitish, long-haired caterpillar about two inches long, with 

 three dark hair pencils along the median line, one each on the second and third thoracic 

 and eighth abdominal segments, occurs in midsummer on various food plants. 



This caterpillar is a rather general feeder, having been recorded on 

 ash, wild cherry, willow, sassafras, alder, blackberry, bayberry, azalea, 

 viburnum, hazel, ironwood and gall berry. It is clothed with long, 

 yellowish hairs which bend backward and the body beneath is marked with 

 yellowish white. The long, yellow hairs part along the median line, where 

 there are also a few short black hairs, giving a distinct black marking. 

 The eggs are laid the latter part of June, hatching early in July, the 

 larva requiring about 30 days to complete its growth. A parasite, 

 Eremotylus macrurus Linn., has been reared f^rom this insect.

Hylotoma macleayi Leach 

 Black-headed, yellowish green, black-spotted, false caterpillarlike larvae nearly 

 inch long, feed in August on chokecherry foliage. 



This larva has been carefully described 1 by Mr J. G. Jack of Jamaica 

 Plain, and his account follows : 



Full grown larva from 15 to 18 mm long. Head black. Body 

 flattish ; pale yellowish green, with four distinct lines of black spots along 

 the back extending from the head to the anal segment ; and with some 

 minute, less regularly arranged spots or dots along the sides above the 

 fleshy projections which characterize larvae of this genus. Each fleshy 

 projection bears a long narrow black spot. The anal segment is sur- 

 mounted by a large irregular oval black blotch and is brown above the
