914 THE BUTTERFLIES OF NEW ENGLAND. 



spiracles luteous, witli a narrow, fuscous ring. Loirs and prologs pallid groon. 

 Length, 3 mm. ; breadth of head, .35 mm. 



Fourth stage. Head piceous. Body pale green with a darker green dorsal stripe, 

 broadest on the thoracic segments, somewhat pallid subdorsal ridges and the sides 

 tinged with grisoous from the numerous dusky ringed annuli and papillae. Caruncles 

 of eighth abdominal segment (first noticed in third stage) pallid, the spicules orange 

 or pale salmon ; when at rest they are not wholly withdrawn but look like fleshy cups 

 with corrugated edges and are a little more than .1 mm. in diameter; midway between 

 spiracles of same segment is a long, erect, tapering, straight, spiculiferous, needle- 

 like spine of a dusky color and about as long as the longest hairs. There is also a 

 broad, tr.ansverse cleft between the spiracles of the seventh abdominal segment, occu- 

 pying at least a third of the space between the spiracles. 



Last stage (75 : 37, 44). Head (79 : 38) piceous ; labrum pallid at base, beyond dark 

 castaneons; antennae pale ; ocelli black; mouth parts pale green. Body dark green, 

 with a fuscous dorsal stripe, from the second thoracic segment backward, enforced 

 by black points, especially near the edges of the segments. Whole of first thoracic 

 segment infuscated. Sides of the abdominal segments between the spiracles and the 

 pallid green infrastigmatal fold dull vinous, becoming brownish posteriorly; sides 

 above sjjiracles marked with a couple of bands of short, pale brownish fuscous 

 lunules separated from each other by their own width, the convexity upward, each 

 upper lunule of one segment also forming with the lower lunule of the next suc- 

 ceeding segment an interrupted oblique line alternating with a series of oblique pale 

 lines. Whole body, between the stigmata and the dorsal stripe and especially at the 

 edges of the latter, besprinkled with pallid stellate papillae, each bearing a short 

 brown spiculiferous hair, and with black, stellate, papillate points beaiMng a shorter 

 brown spiculiferous hair. Legs green, with long castaneons claw; prologs green. 

 Length, 7.5 mm. ; breadth, 2.5 mm. 



Chrysalis (84: 42, 47, 48). Pale green, the abdomen brownish yellow, the thorax 

 and wings distantly and minutely spotted with l)lackish fuscous ; wings with about 

 three narrow, longitudinal, blackish bands, oblique with respect to the body, extending 

 from below upward and backward ; a blackish dorsal stripe interrupted on the abdomi- 

 nal segments ; a suprastigmatal series of rather short, oblique, blackish dashes on 

 the abdominal segments, and a longitudinal dash in its continuation on the meta- 

 thorax; hairs white, the spicules blackish; spiracles luteous. Length, 7.25 mm.; 

 breadth at abdomen, 1.75 mm. ; length of thoracic hairs, .6 mm. ; length of abdominal 

 hairs, .5 mm. ; height at abdomen, 1.5 mm. 



Distribution (24:,")). This thread-tailed and smallest of New Eng- 

 land blues is the most widely distributed, not only occupying the full 

 extent of our Alleghanian and Carolinian faunas, but occurring both north 

 and south of them and extending from the Atlantic to the Rocky Moun- 

 tains and in the north to the Pacific. It has been found as far north as 

 "arctic America" [Great Slave Lake?] (E. B. Eoss, Brit. Mus. ), Devil's 

 Portage, Liard Eiver, Lat. 59° 25' N., Long. 126° 10' W. (McConnell) 

 and the mouth of the Saskatchewan Eiver ( Scudder) , although the only 

 other points north of the United States from Avhich it is reported are 

 nearer the boundary, such as DufFerin and Woody Moimtain (Dawson), 

 London, Ont., where it is "not very common" (Saimders), Ottawa, a 

 single specimen (Fletcher), Chateaiiguay Basin (Jack), and Montreal 

 rare (D'Urban, Lyman). Southward it occurs not only as far as the 

 Gulf of Mexico — Apalachicola, Fla. (Chapman), Alabama (Go88e),but 

 even in Central America — Nicaragua and Honduras (Brit. Mus.), south-
