specimen at Turkey Creek Junction, which may be referable to this species, 

 but it is certainly not a common species in the Territory. 



MELITLEA ANICIA, Doubleday. 

 Melitcea Anicia, Edw., Proc. Ent. Soc. Phila., 1862. 



The expedition of 1873 took this species in the South Park, Colorado; 

 I did not meet with it in the Territory. Mr. Henry Edwards writes con- 

 cerning- it: — 



"About this species there has been considerable confusion, Boisduval 

 having unhesitatingly stated its identity with Editha, Boisduval. This, how- 

 ever, is an error. In a long series of this species, the form of the wing will 

 alone be sufficient to distinguish the two forms. 



" In Editha, the apices are rounded, and the wings are broader than in 



Anicia, while the ground color of the latter may be called red, that of 



Editha being black with red and white tessellations. Anicia is a mountain 



species, and is extremely abundant near Virginia City in May. I have 



taken it in several spots in the Sierra Nevada, particularly in Bear Valley, 



Placer County, and near Donner Lake. The caterpillar has been described 



to me as wholly black, feeding on a species of Primus, but I am unable to 



verify this statement from my own observations. I am inclined to think 



that 31. Nubigena, Behr. will be found to be a depauperated form of this 



species." 



MELIT^A NUBIGENA, Behr. 



Melitcea Nubigena, Behr., Proc. Oal. Acad. Nat. Sci., 1863. 



31. Nubigena is quite common throughout the mountain district of Colo- 

 rado in June and July. Several larvae, probably of this species, were found, 

 usually near the ground, concealed in the herbage or on the stems of their 

 food plant, an indigenous species of Plantago. The ground color of these 

 larvae is white, slightly marbled with black ; the head is black, bilobed, 

 hairy. On the second segment is a black, collar-like mark. Each of the 

 succeeding segments, except the last, bears seven black spines, finely bris- 

 tled. The bases of the dorsal row yellowish ; those of the adjacent rows 

 black, and so on, alternating. Length, 1 inch. One larva suspended itself 

 June 19, and became a chrysalis the next day. Pupa whitish-gray, marked 

 with black and yellow dots, much as in Phaeton.
