marking the position of the upper tail. The fulvous patch extends inward 

 towards the base of the wing instead of following the outer margin, and 

 merges gradually into the ground colour of the wing, which is not so dark, 

 as in Autolycus, being more of a yellowish brown. Under side more of a 

 light yellowish brown than fawn colour. The marginal row of crescents is 

 wanting, and the discal macular row of spots is very indistinct. The 

 black spots at anal angle faint. Fulvous lunules obsolete, except one in 

 third space from anal angle and a few scales in the fourth space. Blue 

 patch in third space, though faint. Types : one male from Utah and 

 one female with California label, for the accuracy of which, however, I 

 cannot vouch, as I received it from a dealer. I am inclined to regard this 

 as a desert form of Autolycus, but until its position can be settled by 

 more material, il may be regarded as distinct. 



Pyrgus Polmgii, n. sp. — Expanse, one inch. Upper surface brown- 

 ish black. Fringes fuscous. Marked with small while dots as follows : 

 Three subapical, close together in a row from costa, the middle one 

 minute, one in cell, three in a longitudinal row below cell, the middle one 

 largest, separated about one-sixteenth of an inch from inner margin, one 

 faint, one close to inner margin a little beyond middle. On secondaries 

 is a mesial curved row of three or four parallel to margin. Under surface 

 disc of primaries blackish brown, costa and outer fourth considerably 

 lighter, more of a yellowish brown, inner margin grayish. Inner two- 

 thirds of secondaries dark brown, outer third yellowish brown. Spots on 

 under surface as above, only larger, and an additional spot in cell on 

 secondaries. Head, thorax and abdomen blackish brown above, fuscous 

 beneath. Antenna? blackish above, joints narrowly yellowish white, tip 

 yellowish brown, beneath tip and base of club brownish, medium portion 

 yellowish, shaft brown ringed with yellow. Types : four males, four 

 females. Huachuca Mountains, Arizona. July. 



Pseudalypia Geronimo^ n. sp. — Upper surface black with a slight 

 brownish reflection which is more marked on secondaries. Fringes a 

 shade lighter. Secondaries without markings. Two large quadrangular 

 light yellow spots on primaries, forming a band across wing from costal 

 edge at junction of middle and outer thirds to inner angle. To the inner 

 side of the costal spot is a narrow band of bluish metallic scales. With 

 a lens the brownish lustre to the wings is shown to be due to a sprinkling 

 of bronze metallic scales over the black ground colour. In one specimen 

 there are a few yellowish scales in the region of the discal dot, and a few
