1472 THE BUTTERFLIES OF NEW ENGLAND. 



dusky ; hairs white, labrum and base of antennae and whole base of labium pale. Body 

 much as in the previous stage but with more of a hoary tinge to it, the white dots l)e- 

 coming larger and more abundant, liearing simple, short, tapering hairs. Spiracles straw 

 color; legs pale yellowish green tipped with fuscous; prolegs concolorous witli the 

 under surface of the body. Length, 28 mm. ; breadtli of head, 3.2.J mm. 



Chrysalis (85:34). Head, thorax and appendages dull but glistening olivaceous 

 green, the head and, excepting the eyes, its appendages, the legs, the prothoras, and 

 the posterior borders of the wings more or less infuscated. Front of the head almo.st 

 blackish; the stigmata! guards of the thorax are velvety black. Head and prothorax 

 rugnlose, on the latter with a distinct, transverse trend. Abdomen pinkish brown, faintly 

 mottled with pale dots and with the posterior margins slightly infuscated ; the last 

 two segments tinged beneath with olivaceous. Cremaster strongly infuscated, the 

 booklets castaueous. Spiracles pallid vnth a slightly fuscous areola. Whole l)ody, 

 excepting the wings, but especially tlie anterior half, with very sliort, pale, tapering, 

 sparsely scattered hairs, which become darker on the front of tlie liead. Length of 

 body. 13.5 mm. 



Geographical distribution (28: 1). The distribution of this butter- 

 fly, as far as we know it and as represented on the map, is somewhat 

 peculiar, and evident!}' will be considerabh' modified when our information 

 is increased. Along the Atlantic sea-bourd it occurs throughout the Caro- 

 linian and Alleghanian faunas. It is a common species in the north, Itut 

 probably becomes rarer further south. With the exception of a single local- 

 ity, Dallas, Tex. (Boll), it is not known west of the Atlantic sea-board in 

 the southern part of the United State.s, but in tlie northern part, where it 

 reaches nearly or quite to our northern borders, it extends across the 

 entire continent ; it is found through our entire Pacific coast, where it is 

 either recorded or I have seen specimens from Sau Diego and Arizona, 

 through central California and the Sierra Nevada (H. Edwards) to AVash- 

 ington Territory at Yakoma River (Lintner). In the western half of its 

 range the northernmost point at \vhich it has beeu found is the lust men- 

 tioned, together with Montana and Dakota (Morrison), Lake of the AVoods 

 (Dawson) and Wisconsin (Hoy). It has also been taken in the inte- 

 rior from New Mexico (Edwards) and Arizona through Colorado, com- 

 mon (Packard, Snow and Mead) to the Yellowstone (Allen). East of 

 this its latitudinal range is at once diminished so far as we have any infor- 

 mation ; it occurs in Wisconsin, common (Hoy) and northern Illinois ( Wor- 

 thington). Along the Atlantic sea-board, however, it occurs south as far 

 as Okahum2)ka (Maynard) and other parts of Fiorid:\ (Norton), but it is 

 not noted, curiously, by Abbot, though it was sent me from South Caro- 

 lina by Atkinson, and from "West Virginia by Edward.s. The northern- 

 most localities along the Atlantic sea-board at wiiich it has been reported 

 are Ha-ha Bayou the Saguenay (Saunders, omitted on the map), southern 

 Ontario, taken occasionally l)ut not very common (Saimders), Toronto 

 and Ottawa (Fletcher) and Albany, N. Y., abundant (Lintner). 



In New England it is everywhere pretty common from the valleys of the 

 White Mountains (Scudder), Norway (Smith) and Moosehead Lake, Me.
