COMADIA DOLLI Sp. HOV. 



Ground color of primaries creamy-white. Primaries dusted with blackish 

 scales which tend to form distinct reticulations. Veins faintly black-marked, 

 the black strongest on the lower discocellular vein. In the best marked speci- 

 mens, the reticulations are quite distinct; in others almost lacking, because 

 the blackish markings are faint, not because of a heavier suffusion of black, 

 nor a dispersal of the black scales, but only because of their absence. Secon- 

 daries gray. 



The thoracic vestiture is similar to typical hertholdi but there is a smoother 

 appearance to the thorax. 



Expanse: 28-35 mm. 



A series of 6 5 3 9 from St. George, Utah, 24 May to 7 June, may 

 represent this species ; altho being in general somewhat more heavily marked 

 and less heavily reticulated. If they represent a distinct species, that species is 

 so closely allied to dolli that fresh material is almost imperative to properly 

 separate it.

COMADTA STABILIS Sp. nOV. 



Ground color of primaries pale, so heavily dusted with scattered black 

 scales as to appear quite gray. Veins, especially the median vein, blackish ; 

 this marking most pronounced on the lower discocellular. Area above the 

 cell and below the costa somewhat paler than the rest of the wing. Secondaries 

 dull fuscous brown, veins darker. Averaging considerably narrower winged 

 and lighter bodied than typical bertholdi; thus appearing smaller. Thoracic 

 vestiture with scales a little broader and less hair-like, more as in intrusa. The 

 palpi are somewhat less hairy than usual within this genus, their vestiture more 

 closely appressed. 



A single specimen from Eureka, Utah, ($), 9 July, appears identical in 

 every respect with the type series in which there is very little variation.
