260 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



t. p. line is rounded around the lower end of the cell instead of being 

 angularly produced onto veins 3 and 4 (Mg and Cui), the black t.p. line 

 is outwardly faintly defined by white scales around the cell, and the hind 

 wing has a yellow anal lunule which does not reach the margin at its 

 upper end. The paratype male is much lighter, the black lines accordingly 

 more distinct, t. a. line slightly more angulate inward in submedian fold, 

 t. p. line defined outwardly by light scales both around cell and near inner 

 margin, and the hind wing with the border lighter and narrower, barely 

 defining the anal lunule. The allotype female has the fore wing grayish, 

 similar to fig. 11 of pi. 5, /. c, but even less maculate, hind wing with 

 darker and broader border. The 3 paratype females are lighter, fore wing 

 more brownish, and hind wing with reduced border. These differences 

 could be summarized as : the 2 Tehuacan specimens moderately dark, the 

 4 Orizaba specimens light. 



Expanse: 33-36 mm. 



Male genitalia: (pi. 32, figs. 8-10) Basal lobe of sacculus slightly 

 bilobed ; distal projection of sacculus long. Juxta short, rounded, dorso- 

 laterally developed to above aedoeagus (giving squarish appearance). 

 Aedoeagus with only one large spine on vesica, and no external spicula- 

 tions. 



Female genitalia: (pi. 33, fig. 3) Sternite VII similar to that of 

 mexicana, but the indentation slightly deeper. Ductus bursae short and 

 with the 2 supporting sclerites of approximately equal length. Bursa 

 copulatrix with 3 areas of heavy sclerotinization (areas stippled in fig- 

 ure) : one a curved cone around the entrance of the ductus seminalis, one 

 opposite this merely a sclerotinized area of the bursal wall, the third on 

 the right side terminating anteriorly in a blunt prong ; the last mentioned 

 is also covered at its anterior end with small spiculations — too small to be 

 shown in the figure; heavy spines in bursa as shown, no set of smaller 

 spines in the middle of the bursa on the left side. 



Holotype: cT, Tehuacan, Puebla, Mexico, September, 1908 (R. 

 Muller) (in U.S.N.M.). 



Allotype: 9, same data as holotype (in U.S.N.M.). 



Paratypes: 1 d" , 3 $, Orizaba, Vera Cruz, Mexico, no date (ex 

 Schaus Coll., in U.S.N.M.). 



Genitalically this is the most distinct of all the species of the genus, 

 differing among other points in having only one large spine in the 

 aedoeagus of the male, and having a short ductus bursae and heavily 

 sclerotinized areas in the bursa copulatrix of the female.
