LYCAENINAK: TUKCLA KDWAKDSII. 895 



Mr. S!iuiuk'rs"s ilesiTiptioii diU'ers soiucwliat from mine iiiul particularly in that lie 

 found the ilorsal baiul "enlarging: to an indistinct patch at each extremity, most prom- 

 inent on hinder segments and having a series of spots along its centre from tlfth to 

 ninth [Hrst to llfth abdominal] sognients Inclusive of dull greenish gray, the hinder 

 ones being almost diamond shaped." His specimens were lo mm. long. 



Chrysalis (84 : "20). Dull yellowish brown, slightly glossy, with many small spots of 

 a darl<er sliade of brown fre(|Uently collected into irregular streaks and blotches, par- 

 ticularly in an obscure band along the latero-stigmatal region of both thora.\ and 

 abdomen and a ventral stripe on tlie abdonnnal segments. The network of interlac- 

 ing ridges is composed of smaller cells than in the other species, covering most of the 

 body, as distinct on the sides as on the back and having at their intersecting angles 

 little warts; the hairs are rather distant, very short, as long on the body as on the 

 front, excepting some on the very front edge of the prnthorax which are fully three 

 times as long as the others, tapering throughout, but bluntly pointed, distinctly and 

 very minutely spiculiferous ; the other hairs are equal, bluntly rounded at tip and 

 their spicules so excessively minute as scarcely to be distinguished with a high magni- 

 fying power; spiracles luteous. Length, 10 mm.; breadth, 4.5 mm. : height, 4.25 

 mm.; length of liairs in general, .005 mm. : length of hairs on anterior edge of pro- 

 thorax. .2 mm. 



Distribution (24: 3). Tliis butterHy is a member of the Alleghanian 

 fauna, occupying a comparatively narrow strip of territory, so far as known, 

 from the Atlantic more than half way across the continent. It is rarely 

 found north of Lat. 42', nor, in the east, often south of 40°. West of 

 New England, the northernmost points at which it has been taken are 

 Albany, N. Y. (Lintner), London, Out. abundant (Saunders), Beloit 

 (Ciiamberlain) and Racine, Wise. (Hoy), northern Illinois (Worthing- 

 tou), and in some abundance at several places in Iowa (Allen, Austin), 

 where specimens are larger in size. In the extreme west it has been 

 found in Nebraska (Edwards) and at several places in Colorado — Manitou 

 (Packard), Ute Pass (Scudder) and the cast slope of the Sangre de Cristo 

 Mts. (Frazer). Besides this it is reported as "rare"' at Summit, N. W. 

 Terr., Long. 115° W., 50° N. by Geddes ! Strecker gives it from Texas 

 but without specification, and it nuist be believed erroneously. In the east 

 its southern limits are doubtful (as indeed everywhere) owing to the con- 

 fusion of names in the memoranda received from different persons. A 

 single specimen in the collection of the American Entomological society 

 is marked Virginia with a query, and it is possibly this species which is 

 reported from Pennsylvania (Blake) and Maryland (Uhler) ; but Mr. Ed- 

 wards has not found it in his extensive collections in West Virginia and the 

 most southern localities from which I have seen it are in New England. 



Here it reaches the southernmost boundaries and extends northward into 

 the southernmost portions of the northern states, being apparently limited 

 on the north very closely by the line I have marked out as that dividing the 

 Alleghanian and Canadian faunas. In Maine it was not found by Pro- 

 fessor Fernald at Orono, but a single specimen has been taken by Miss 

 Wadsworth at Hallowell ; and in New Hampshire it has been found at 

 Nashua (Harr. Coll.) and Milford (Whitney). Most of the captures
