THE CACTUS-FEEDING PHYCITINAE — HEINRICH 345 



area; veins faintly outlined in black; a row of more or less obscure 

 black dots on termen between the vein ends; antemedial line inter- 

 rupted, sometimes obscure, in fresh, well-marked specimens its outer 

 dentation much extended and meeting a shade from the inner angula- 

 tion of the subterminal line at the fold (which indicates the normal 

 position of the absent vein Ic) ; subterminal line interrupted, strongly 

 indicated only between veins 5 and the fold and for a short distance 

 from inner margin ; black discal dots at end of cell more or less fused 

 and pronounced ; cilia ocherous-fuscous. Hind wing pure white. 



Alar expanse, 38-45 mm. 



Male genitalia as figured (figs. 3-3c). The genitalia (male and 

 female) present no outstanding specific characters. 



Female. — Similar to the male except that the antennal pectina- 

 tions are shorter, the labial palpi appreciably longer, the fore wings 

 a trifle darker, and the hind wings generally suffused with fuscous, 

 the intensity of the fuscous shade differing in different specimens. 



Alar expanse, 45-55 mm. 



Female genitalia as figured (figs. 42-42a). 



Type. — In Rutgers College collection. 



Food plants. — Opuntia {Platypuntia) spp. 



Distribution. — United States: Texas, Brownsville (Apr., June, 

 July, Aug.), Corpus Christi (Sept., Oct.), Burnet County, San 

 Benito (Mar., Aug., Sept.), Shovel Mountain (May), Kerrville 

 (Apr.), Victoria (Oct., Nov.), Laredo (Sept). 



Forty-one specimens examined. 



Remarks. — This species is most readily distinguished from the 

 others in the genus by its ocherous-fuscous color, which seems to be 

 constant. It is remarkably so in the specimens before me. 0. 

 nephelepasa and subumbrella are decidedly gray in appearance. 



Rather full notes on the life history and larval habits of ywdc- 

 tolineella are given in Dodd's bulletin and the bulletin by Hunter, 

 Mitchell, and Pratt. The latter also contains descriptions of the 

 larva and pupa.

 In removing pectinatella from the synonymy of junctolineella^ 

 where it was placed by Barnes and McDunnough and by Dyar, I am 

 doing so chiefly as a precautionary measure. Hampson described his
