1893.] lOl [Packard. 



A moth appeared in the breeding box June 6, and another June 7 ; it 

 rested on the sides, with its wings depressed and the abdomen raised in 

 the air. 



Cocoon. — Rounded oval, of the usual shape ; length, 6.5 mm. ; shorter 

 diameter, 4.6 mm. 



My larva and also some excellent figures, with details, agree with Mr. 

 Dyar's description of the larva of P. eUgans in Can. Ent., Dec, 1891, 277. 



I have two good figures by Mr. Bridgham of the larva of P. geminata, 

 which agree well with Dyar's description in Can. Ent., Dec, 1891, p. 277, 

 except that the tail is not slightly tipped with reddish. It was found 

 on the chestnut, September 16, and also on the wild cherry. 



The Partial Life History of Lithacodia pasciola 

 (Herr.-Schaeffer). 



I am indebted to Miss Emily L. Morton for the opportunity of studying 

 the freshly hatched larva of this species, as about the middle of June she 

 very kindly sent me the eggs from New Windsor, N. Y., which hatched 

 out at Brunswick, Me., July 18 or 19. 



Egg. — Irregularly oval ; length, 1 mm. ; thin, scale like, and the shell 

 very thin and transparent. As they had dried on the paper on wiiich they 

 were laid, it is impossible to see whether the shell is marked with polygo- 

 nal areas or not.* 



The Freshly Hatched Larva (Fig 15). — Length, 0.8 mm. The body 

 is wdiite, tinged with yellowish ; and the head instead of being white, as in 

 Adoneta and Empretia, is somewhat amber colored ; the eyes are black 

 and distinct ; the body is about four times as long as thick and slightly 

 thicker through the second and third thoracic segments than elsewhere. 

 The thoracic legs are unusually small. There are no tubercles, and the large 

 setfe appear to arise directly from the skin ; there are two dorsal and two 

 subdorsal rows, one of each on each side. The grandular setae (Fig. 16) 



* I also received from ISIiss Morton the eggs of Phobelron pithecium and of Euclea quer- 

 ceii. Like tliose described in this paper, they do not present good generic or .specific 

 characters, enabling them to be readily identified. I give, however, the following de- 

 scriptions of them. 



Egg of Phobdron pithecium. —-Tha sexes were mated July 3. The eggs are orbicular- 

 oval, flat, scale-like, rather large and of a more definite shape than usual ; 2 x 1.5 mm. ; 

 somewhat raised in the middle, but with very thin edges, resembling a shallow plate 

 turned bottom-side up. Some fortunately laid ou ghiss showed very plainly that the 

 very thin shell is covered with irregular, usually elongated polygonal markings; here 

 and there one being one-third smaller than most of the others. As usual they are laid in 

 an irregular group, partly overlapping each other. 



Miss Morton writes me that the males seek their mates bet^veen nine and ten 

 o'clock in the morning, and that she never succeeded in mating a captive female at any 

 other time. She adds that the larva will feed on the chestnut, maple, hazel, oak, wild 

 cherry, and possibly on other trees. 



Egg of Euclea querceti.—Qxnie regular orbicular-oval in outline ; thin, scale-like : 2 x 1.5 

 mm. ; the edge is quite definite, and the polygonal areas much as in those of Pfiobelron 

 pithecium.
