LYCAENINAK: 1II;()DE.S IIYPOPIILAEAS. 1003 



fuscous. Legs slightly infusciiteil. tipped M'itli fuscous; prolesis of tlie color of tlie 

 under surface. Length, 3.5 mm. ; breadth, 1 mm. ; heiglit, .S mm. 



Fiiurth stage. Head pale yellowisli green, edged below, including the bottom of the 

 ocellar Meld, with blackish fuscous, the suture of the triangle marked with fuscous; 

 labrum rimmed with whitish; mandibles reddish fuscous. Body as previously de- 

 scribed; in some instances a dorsal stripe and a broad, ventrostigmatal band around 

 the whole body, dull roseate, the color apparently conllnod to the hairs. Length, soon 

 after moulting, 5 mm. ; breadth, 1.75 ram. ; height. l..'J5 mm. 



Last starie (75:42; 79:40). Resembling the former altogether, excepting that all 

 the specimens with roseate stripe and margin which I have reared become wholly 

 green after the last moult. Length, 14.5 mm. ; breadth, 4.25 mm. 



Chrysalis (84 : 40). The general color is light brown or livid, tinged with very pale 

 yellowish green. The thorax is darker and tinged with ferruginous, dotted and spotted 

 ■with bl.ackish fuscous, a subdorsal pair at the highest point of the mesothoras. There 

 is a rather broad, blackish fuscous, dorsal streak on the mesothorax, and on either side 

 a similar dark band follows the hinder edge of themesonotum and reaches the base of 

 the wing; the dorsal region of the abdomen is infuscated. The lower surface is paler; 

 the eyes are reddish brown, and the interspaces of the wings are mostly filled with 

 blackish brown streaks darkest toward the upper border. On the abdomen are many 

 rows of roundish black dots arranged in longitudinal series as follows : a faint, dorsal 

 row placed centrally ; a faint, subdorsal series placed posteriorly ; a laterodorsal 

 series placed anteriorly ; a latei-al series placed anteriorly ; close to it a laterostigmatal 

 series placed posteriorly; a stigmatal series placed posteriorly, further back than the 

 other posterior dots and composed of two continent dots ; an inf rastigmatal series placed 

 posteriorly, and on the posterior segments having a companion on the anterior part 

 of the segment ; a lateroventral series placed centrally and a double subventral row. 

 Raised lines covering the body russet, the short, fine hairs reddish or blackish; the 

 lower equal portion of the pedicels of the fungiform papillae (86 : 33) blackish fus- 

 cous, the disks colorless. The warts on which the papillae are mounted are .0127 mm. 

 In diameter, the pedicel half that diameter, and the equal portion .047 mm. long ; the 

 expanded portion is .025 long and the disk .055 mm. in diameter. Length, 0.5 mm. ; 

 height, 3.5 mm. ; bfeadth at thorax, 3.25 mm. ; breadth at abdomen, 4.25 mm. 



Comparisons. Harris, in some unpublished notes upon this species, 

 which he was really the first to distinguish from H. phlaeas, says: "It 

 not only differs from phlaeas in the color and more distinct spots of the 

 under side of the under wings, but it exhibits on the upper side of these 

 wings a black, central line and a submarginal series of black spots before 

 the fulvous band much more distinct than do the European specimens of 

 phlaeas. The external angles of the anterior wings are more rounded and 

 the emargination near the anal angle of the posterior wings is not so deep, 

 and consequently the anal angle not so pronounced as in phlaeas of Europe." 



I have not been able to make direct comparisons of the early stages, ex- 

 cepting of the egg. This in hypophlaeas agrees entirely in size and propor- 

 tions with that of phlaeas, but the surface is more rugose, the rugosities more 

 connected in tortuous lines, and are also slightly more pronounced in 

 hypophlaeas than in phlaeas, besides which the cells in our species are 

 slightly smaller and consequently more numerous. 



Distribution (25 : 3). This member of the Alleghanian fauna is wide- 

 spread, invading the southern portions of the Canadian fauna and extend- 

 ing to the Pacific coast ; its very abundance has prevented its specification
