884 THE BUTTERFLIES OF XEW ENGLAND. 



which at first was pale yellowish brown but afterwards changed to a very 

 dark mahogany brown ; the segments were marked with very fine trans- 

 verse lines, about .042 mm. apart, and at the posterior end had a band, 

 occupving one-fourth of the segment, made up of seven or eight rows of 

 minute bead-like prominences, crowded closely together, each i-ow about 

 .17 mm. wide; length of puparium, 4.75 mm. : breadth, 2.3 mm. The 

 larva left the caterpillar on the 20th of June and emerged as a tly on 

 July 2 ; it proved to be Exorista theclarum (89: 17, 19), the same found 

 on other Lycaeninae. 



Another larva from this same plant, now presumed to belong to T. 

 liparops, which I was trying to rear was foimd in a few days hanging by a 

 short thread from a Yaceinium leaf while a parasitic grub was forcing its 

 way out near the posterior extremity of its victim ; when about half 

 emerged, it began to weave a cocoon and after an hour's work had nearly 

 completed one-third, when the thread broke and the whole fell to the 

 groimd ; the grub now pushed its way completely out and constructed a 

 new cocoon against the old one and on the bottom of the vessel ; the co- 

 coon was very delicate, made of white silk, 3 mm. long, and 1 mm. broad 

 with some outlying tough threads to secure it to the svu'face on which it 

 rested. Unfortunately the parasite, the only hymenopterous parasite 

 known, died in the chrysalis state. 



Desiderata. In view of the behavior of its allies, it would be interest- 

 ing to discover whether the egg ever hatches before winter or, if not, 

 whether the larva is fully formed within the egg before winter : one would 

 think the summer the more favorable time for it development. Fuller 

 descriptions of the earlier stages of the caterpillar are needed, and doubt- 

 less, from its polyphagous habits, many more new food plants are to be 

 found. Its hymenopterous parasites are unknown.
