terminal line. Beneath powdery dull gray, primaries with a vague discal 

 blotch, secondaries with a lunula and an exterior line. 



Expands i. 25-1. 60 inches = 30 to 40 mm. 



Habitat: Winnipeg, Manitoba, June and July (Hanham) ; Pull- 

 man, Washington (Piper). 



A good series of specimens shows little variation save in the shade 

 of the ground colour. In genital structure the insect resembles desperata; 

 but in general appearance it is much more like indirecta, niactata or 

 divest a. 

 Hadena (XylopJiasia) Barnesii, n. sp. 



In general appearance resembling auranticoloj-, and heretofore con- 

 fused witli that species. It is smaller, however, in average expanse, 

 much paler and less red in ground colour, and altogether a more sordid, 

 less brilliant species. The violet shading in the s. t. space of the old 

 species is' replaced by gray or whitish in the new form, and the 

 secondaries are of a dull, even smoky gray, without a trace of yellow or 

 red in the ground or whitisli at the base. All the markings are present 

 on the primaries, less strigate and better defined than in auranticolor ; 

 but without preceding dashes to the W, or interspaceal streaks in the 

 terminal space. 



Expands 1.50-1.68 inches = 37-42 mm. 



Habitat: South Dakota (Truman); Glenwood Springs, Colorado, 

 in September; Yellowstone Park, Wyoming (Dr. Barnes). 



A series of seven specimens has been compared with a similar 

 number of auranticolor before the species was decided to be distinct. 

 There is no difficulty in se])arating the two forms, but it is not so easy to 

 localize the differences. The much duller primaries and the very evenly 

 dark secondaries are the most obvious features. 



The sexual parts of tlie male are disproportionately small, but of the 

 same general type as in auranticolor. 

 Hadena (Xylophasia) dionea, n. sp. 



Ground colour an even, obscure fuscous gray without contrasts. 

 Head with a dusky frontal line, collar with a blackish central line, 

 patagiae with a black submargin. Abdomen mouse gray. Primaries 

 with all the maculation present, but obscure. A short black basal streak. 

 Basal line geminate, smoky, marked on the costa only. T. a. line 

 geminate, smoky, incomplete, outwardly curved, and with small out- 

 curves in the interspaces, marked by an oblique black streak on the
