Map 14. — Distribution of Prodoxus pulverulentus (black triangles) and Prodoxus cinereus 

 (black circles) (see maps 4 and 5 for distribution of host). 



Type. — Lectotype (designated by present author), 9, San Diego 

 Co., Calif., May 20, 1886, seed pods of Y. whipjplei, USNM 426; in 

 the U.S. National Museum. 



Type locality.^ — Santiago, San Diego Co., Calif, (lectotype). 



Recorded host. — "Yucca whipplei Torrey" (RUey, 1892a). Larva 

 bores in fruit of host. 



Distribution. — Presently known only from southern California 

 (map 14). 



Discussion. — From casual examination, P. marginatus and P. 

 pulverulentus appear quite distinct. Comparisons of genitalic struc- 

 tures and life histories, however, indicate then- affinities to be very 

 close. Although supporting data is somewhat scant, it is possible 

 that the distributions of the two species are not sympatric, with P. 

 marginatus occurring more to the north. If this is so, then it may be 

 further true that the two moths are restricted to the two primary 

 growth forms of Yucca whipplei as discussed under T. maculata 

 extranea. Largely because the wing patterns of P. marginatus and 

 pulverulentus appear amply distinct, with no evidence of hybridiza- 

 tion nor intermediacy, I have treated them as separate species.
