FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



anteriorly. When extended, the front of segment 1 is pale green, and 

 the incisure of segments 2-3 is shining black. The three dorsal spots 

 are pale greenish-yellow ; the central spot, on segment 7, has a /Ze?<r- 

 de-lis form ; the following one, on segment 9, is small and geminate ; 

 and on segment 11, in a number of the larvas, is a fourth spot, usually 

 smaller than the preceding. Of the tubercles, arranged in subdorsal 

 rows, those on segment 8 are the largest, exceeding in height and 

 diameter of base those on segment 2, and are directed somewhat back- 

 ward. A lens shows short hairs over the body, and on the summit of 

 the tubercles are larger ones, curving inward; the body is lined with 

 short, black streaks. From the tips of the lappets long, black hairs 

 of an unequal length are given out, while tlieir margins and interven- 

 ing portions of the body bear numerous shorter gray hairs, many of 

 which are barbed ; these form a fringe directed downward when the 

 larva is resting on a small branch, wholly concealing the legs and 

 nearly hiding the long prolegs. In addition to these lappets (a sub- 

 stigmatal row), there is a single one of a little larger size on the first 

 segment, in front of the first spiracle, the hairs of which project along 

 tlie side of the head. All the lappets are margined with a black line 

 whicli is more distinct upon the anterior one: the first three point for- 

 ward, the others backward. The larva has the power of elevating or 

 depressing one or more of the lappets at pleasure: when in motion, 

 they are borne horizontally; at other times, all but the thoracic ones 

 are depressed. The prolegs are obscure greenish. The ventral re- 

 gion is of the same color, with a lenticular blackish spot on the first 

 five segments. 



The Cocoon. 



The first cocoon was spun on the 17th of May, forty-three days after 

 the earliest hatching of the Lirvfe. Within two days, seven cocoons were 

 made: in all, thirty-three were obtained. For 

 the reason that the twigs upon which the 

 larvte had been fed Avere of a small size and 

 without the branches at the giving off of 

 which the cocoous are usually placed, nearly 

 all were spun upon the flat sides of the feed- 

 ing cage, where tliey presented the appear- 

 ance shown in Fig. 20 : none were placed in 

 the angles or corners. Their ground- work 

 usually extended at some distance beyond the 

 cocoon proper, for while its average length 

 was less than one inch, that of the ground- 

 work often exceeded one inch and a half. 

 The cocoon is of a pale gray coior, elongate
