I'AMIMIII.IDI : l.lMOrilOlIKS :\IA\ATAA(,»rA. 1723 



composed of a broailcr, nnterior, elevatcil, convex collar and a posterior, slenderer, 

 flat Held, both extending; to a nilniite, triangular, plceous piece jnst above the fuscous 

 spiracle. Front pair of legs plceous; other legs and prologs green with the claws of 

 former a little dusky. Appendages (86:52) pellucid, about one-third as long as the 

 segments. Long, recurved, sweeping lialrs on last segment. Length, 3.25 mm. ; 

 breadth of head, .(is mm. ; length of bristles, .00 mm. 



Stcond stmje. Head (80 : 04) piceous, minutely rugose witli very short and exces- 

 sively tine scattered hairs. IJody equal, pallid green, tlie Idinler segments cmbi'owned, 

 with a faint, narrow, dusky, dorsal stripe and a pallid s\il)stigmatal band at edge of 

 snbstigmatal fold ; whole upper surface profusely dotted with brown warts, emitting 

 each an extremely short, tapering, black hair; some specimens are more heavily flecked 

 than others. Thoracic shield piceous, smooth, separated considerably from the trian- 

 gular, suprastigmatal patch, the portion of the segment in front of it milk white; a 

 few long, curving, black hairs on the last segment which is very broadly rounded 

 behind; spiracles piceous, those of the first thoracic and eighth abdominal segments 

 forming a crateri form tubercle; legs and prologs of the color of the under surface 

 which is pallid, the claws of legs fuscous anil the whole front of the flrst pair of legs 

 blackish fuscous annulated with white at the incisures. Length, 7.5 mm. ; width of 

 head, .8 mm. ; of middle of body, 1.2 mm. 



TJtird stage. Does not difler from the previous stage except in a slightly more pro- 

 nounced rugosity to the head, in a little darker tone to the body, owing to the greater 

 size and depth of color of the brown warts sprinkled evei'y where. Width of head, 

 1.2 mm. 



Fourth stage. Head black, densely but rather delicately rugose with numerous fine 

 and very short tawny hairs ; eye specks and antennae piceous ; labrum castaneous edged 

 with pallid. Body parallel sided, broadest rather behind the middle, the first thoracic 

 segment pallid with a piceous shield, with scattered, short hairs arising from minute 

 and low, piceous warts; rest of body dingy, almost fuliginous brown in general 

 effect, arising from multitudinous, minute, black warts with a smoky surrounding on a 

 dirty, pallid base. The last segment is, however, lighter, and there is a slender, 

 dusky, dorsal line on the other abdominal segments due to the extension here of the 

 fuliginous surrounding of the black warts ; from these last arise excessively short, pale 

 hairs. Lips of spiracles pallid with a narrow, black areola, the large ones infuscated 

 centrally. Legs piceous, the last pair only at tip, the rest luteo-fuscous. Prolegs 

 like the body. Length, 10 mm. ; breadth of head, 1.6 ram. ; of body, 1.6 mm. 



Distribution (32 : 2) . This butterfly is a characteristic member of the 

 AUcglianian t'aiina. The points from which it has been reported outside of 

 New England, although distant from each other, are Init few in number : 

 Canada West (Brit. Mus.), Illinois (Worthiugton), Fort Niobrara, 

 Nebraska (Carpenter), Iowa (Austin), Maryland (Harris), Albany and 

 Bethlehem, N. Y. (Lintner). Geddes even states that he found it, but 

 very rare, at Fort MacLeod, southern Alberta, which is a long way from 

 any known neighbors. Aaron even thinks Hesperia baracoa Luc. of Cuba 

 and southern Florida the same species, which is hardly probable from 

 what we so far know of its distribution. 



In Xew England it has also been found in distant stations. The north- 

 ernmost are Brunswick (Packard) and Portland, Me. (Lyman), and next 

 to them Walpole, N. H. (Smith). It has been several times taken in the 

 neighborhood of Boston (Merrill, Faxon, Guild, Sanborn, Scudder) and in 

 the Connecticut valley at Springfield (Emery), Deei-field, Mt. Tom
