THE CACTUS-FEEDING PHYCITINAE HEINRICH 397 



Types.— In Eutgers College collection {femaldialis) \ United 

 States National Museum {cinerella) ; Museum National d'Histoire 

 Naturelle, Paris {gigantella) . 



Type localities. — Arizona {fernaldialis^ gigantella) ; Santa Rita 

 Mountains, Ariz, {cinerella). 



Food plants. — Ferocactus wislizeni (Engelmann) and probably 

 other species of Ferocactus; Peniocereus greggii (Engelmann), one 

 reared specimen from Maricopa County, Ariz., in National collection 

 60 labeled. 



Distribution. — United States: Arizona, Catalina Springs (Apr.), 

 Oracle (July), Tucson (June), Baboquivari Mountains (Apr., May, 

 June, July, Aug., Oct., Nov.), Christmas, Redington, Pinal Moun- 

 tains, Santa Rita Mountains (May, June), Huachuca Mountains 

 (Aug.), Douglas (Apr., May), Mohave County (May), Sells P. O. 

 (Indian Oasis, Apr.), Dewey (June), Maricopa County (July), "en 

 route from Dewey to Salome" (Apr., May) ; Califomia, San Diego 

 (May, Oct.). 



Seventy-three specimens examined. 



Remarks. — The synonymy as given here was established by Dyar. 

 However (in 1915, 1925, and 1928) , he also listed the Mexican species 

 longipenneJla Hampson and its synonym elongatella under fem- 

 aldialis, incorrectly, I believe, because the forms from Mexico and 

 the United States have different male antennae. In his original 

 description of gigantella Ragonot gives the type locality as "Mexico 

 or."; but in his Monograph of the Phycitinae he cites Arizona as 

 the only locality. If the later citation is correct, gigantella is pre- 

 sumably a synonym of femaldialis. If, however, eastern Mexico is 

 the locality, the name gigantella will probably replace longipen- 

 nella for the Mexican species. It is quite likely that femaldialis 

 also occurs in northern Mexico near the Arizona border; but we 

 have no specimens from that country. All the specimens in the 

 National collection that have been identified as feTmaldialis are 

 longipennella. 



In addition to moths reared from Ferocactus and Peniocereus the 

 National collection contains the moths referred to by E. A. Schwarz 

 (Psyche, 1899) as reared from larvae "feeding in decaying pulp of 

 the Giant Cactus." One of the specimens (a female) bears the fol- 

 lowing label in Schwarz's handwriting: "bred from cocoons under 

 Giant Cactus. Em. Apr. 15." From this it would appear that Car- 

 negiea gigantea (Engelmann) may also be an occasional host.
