Heterocampa simulans sp. nov. 



Antennae yellowish. Head and thorax greyish-rufous. Abdomen fusco- 

 luteous, paler beneath. Primaries : ground color deep violaceous tinged with 

 rufous; veins somewhat marked by fuscous; a slight basal dash present: basal 

 line double, black, obsolete below the basal dash ; t. a. line double, black, waved 

 from costa to inner margin, preceded by a rufous shade ; discal spot crescent 

 shaped, black, slightly edged by rufous; t. p. line black, waved from costa to 

 inner margin; s. t. line poorly defined, marked mesially by fuscous and rufous 

 shades ; followed by a subapical pale shade ; terminal line black, single. Sec- 

 ondaries : white, with the fringe checkered by black at the extremities of the 

 veins. Beneath: primaries; ground color white, marked by a fuscous medial 

 shade, shadings along costal and outer margins, and on the veins : secondaries 

 white, only slightly marked by fuscous on costal margins, and on veins ; and 

 with small dots in the fringe at the extremities of the veins. 



Expanse: 48 mm. 



Closely allied to rttfinans Dyar and possibly a race of that species. 

 Dr. Dyar saw the type, which bears an old label "Heterocampa obliqita 

 Pack. Identified by Dyar" ; and considers it a distinct species. It is 

 quite possible that the locality label "West Iowa" may be erroneous, 

 but apparently there is no described exotic or native species of Hetero- 

 campa at all closely related except rufinans. The Barnes Collection 

 possesses seven males and two females of rufinans from the vicinity 

 of Glenwood Springs, Colo., June, July and Aug., wliich agree well 

 with Dr. Dyar's type and show little variation. 



Type locality: West Iowa. 



Number and sexes of types: Holotype $, unique. 



Heterocampa incongrua sp. nov. 



Antennae brownish-yellow. Head and thorax mottled olivaceous and 

 black. Abdomen: light yellowish-brown above, overlaid by some grey, tufts 

 black; below, cream, colored. Primaries: ground color olivaceous, strongly 

 tinged with rufous brown and green; veins more or less marked by black; 

 a trace of black basal dash present; t. a. and t. p. more or less obscured, suf- 

 fused, blackish, double, waved from costa to inner margin ; s. t. line obscure, 

 marked by a series of sagitate black spots between the veins; discal mark 

 crescent shaped, strong, black, outlined by rufous-brown. Secondaries: white, 

 the veins and margins somewhat marked by black. Beneath: ground color of 

 all wings white; primaries more or less suffused with black and appearing 

 grey especially along the cost?! and outer margins; secondaries nearly pure 

 white except for a patch of black scales at the anal angle and black dots check- 

 ering the fringe at the ends of the veins. 



Expanse: $, 43-47 mm.; 9, 53 mm.
