small, simple, and terminating in a long bayonet, turned up- 

 wardly; the aedoeagus is peculiar in that its base is T-shaped, in 

 nature set in a horizontal plane.

17. Pholisora arizonensis Mabille & Boullet 



Under the name Hesperopsis arizonensis these authors have 

 described an insect in a recent paper.^^ A free translation of 

 the original French description follows. 



"Four wings black with along brown fringe cut into here and 

 there with yellow. Primaries above with two apical points and 

 two other points not so distinct placed obliquely in three and 

 four; a terminal row of clear fpale) points on the external border; 

 some appearance of yellowish scales on the disc. Secondaries 

 above of a uniform black with a terminal row of clear points 

 hardly visible, and an indistinct dash in the cellule. Primaries 

 below uniform black brown with two well marked apical points, 

 some white hatching along the costa above the apical points, 

 one perceives the two points on three and four and the terminal 

 row of clear points. Secondaries below; on the ])rown-black 

 ground is easily seen the terminal row of clear points and a 

 sickle-shaped trace in the cellule. Palpi white; at the ])ase of 

 the antennae a little tuft of white hairs. 



Arizona, U. S., one cf : Boullet Collection, Paris INIuscum." 



We think this is alpheus. 



18. Pholisora libya Scudder (Fig. 17.) 



This .s])e('ies lacks the costal fold. Libyo varies greatl}' in the 

 num])er of white s])ots on the wings, ])oth al)ove and below. 

 Lend of Edwards a])pears to be the same s])ecies as /v7>//a, des- 

 cribed from specimens having few spots on the primaries above 

 and one spot on the secondaries below. The genitalia of libya 

 and of the one spotted form (lena) are alike. 



The type information of libya is, one male, two females, 

 "Beaver Dam," April 20-28, Arizona (25 miles to west of south 

 of St. George, Utah). The type information of lena is, one male, 

 one female, Montana. We have specimens of this from the 

 ^^'llite Piver, Colorado.
