The type of perfusa has not been matched ; and is listed as a form 

 of race discalis simply because it was described as a dimorphic form 

 of eileena. Apparently the male and female types are quite different 

 in color and strength of maculation. 



Mr, Schaus has compared specimens with the types of discalis, 

 infnsa and eileena; a California specimen agreeing best with discalis; 

 and an Arizona specimen, with eileena ; the reverse of the localities of 

 the types. 



LiTODONTA GIGANTEA sp. nOV. 



Head and thorax dull grey, black, and white, mixed. Primaries : ground 

 color violaceous-grey-white so heavily dusted with black scales that the insect 

 appears nearly a uniform dull grey; all ordinary lines obsolete except the s. t. 

 which is very faintly indicated by a darker shading ; a black basal dash bordering 

 the costal side of vein 1, surmounted by a violaceous-white shade ; discocellulars 

 marked by a long, thin, black, erect crescent ; veins marked by black scales ; 

 fringe grey interrupted by a continuation of the black veins. Secondaries : pale 

 dirty brown with somewhat darker veins ; fringe similar in color, checkered 

 with darker brown at the extremities of the veins. Beneath : primaries pale 

 dull grey, the veins somewhat darker, no other distinct maculation. fringe 

 checkered with darker grey at the extremities of the veins; secondaries; whitish, 

 veins slightly darkened by a few fuscous brown scales at the outer margin ; 

 fringe whitish checkered by fuscous-brown at the extremities of the veins. 



Expanse: 43 mm. 



The present species is, apparently, an aberrant member of the 

 genus Litodonta, with which it agrees in all essential characters except 

 size and the accessory cell which arises from the extremity of the 

 discal cell, vein 6 arising one-third the length of the accessory cell 

 from the discal cell. 



Type locality: Palmerlee, Ariz. 



Number and sexes of types: Holotype $, no date, unique. 



Heterocampa Dbldy. vs. Disphragis Hbn. 



The authors are cognizant of the fact that the Rules of the In- 

 ternational Zoological Congress apparently would substitute Disphragis 

 for Heterocampa; but pending an answer to an inquiry addressed to 

 Dr. Stiles, the secretary of the International Commission regarding 

 the status of certain Hiibnerian names, it appears safer to use the well 

 known genus Heterocampa, with haplotype //. astarte.
