rarely gray, of forewings darker red. Face with a median black stripe. 



Holotype and six additional females and one male, Jesus Maria, 

 Nayarit, Mexico, June 26, 1955 (B. Malkin) ; topotypic females, July 6 

 and July 27 ; and two females, Arroyo Santiago, near Jesus Maria, 

 Nayarit (UCAL) ; two females Guernavaca Road, August 24 (USNM) ; 

 one female, Mexico (SSM); females from Tejupilco, Temescal tepee, 

 Mexico, June 1 7, July 2, and from 9 miles S. of Guernavaca, Nov. 24 

 and December 9 (GAS). 



This species is named in honor of the late Dr. John Lane, of Sao 

 Paulo, Brazil, a good friend and a noted entomologist, who collected 

 a specimen of this species in Mexico. 



P. lanei is so closely related to P. aterrima Fowler that the male genitalia 

 are identical in the two species. P. lanei is readily separable on the basis 

 of its greater length, its more produced head, and the shape of the 

 abdominal sternum VII of the female.
