A New Variety of Argynnis Nitocris. 



BY WlLMATTE P., AND T. D. A. COCKERELL. 



Argynnis nitocris var. nigrocaerulea n. var. 



$. Upper side: basal half of wings dark purple or purple-black in- 

 stead of blackish brown ; quadrate marks very pale yellowish, slightly 

 suffused with red; underside: marginal band of elongated marks pale 

 green, quadrate spots pale yellow, basal area of wings very dark, being 

 largely suffused with purple-black. 



cT. Under side : basal area of hind wings with ground color cinnamon, 

 very much paler than in 9 



Hab. Beulah, Sapello Canon, New Mexico, middle of 

 August, 1900. This beautiful insect is in some respects inter- 

 mediate between nitocris proper and Holland's var. cicrnlcsccns. 

 It will be readily known by the great difference between the 

 color of the sexes on the hind wings beneath, and the purplish 

 color of the 9 above. Specimens are in Dr. Skinner's collec- 

 tion, and he will doubtless be pleased to show them to those 

 interested.
