Gnamptonychia ventralis n. ^p. 



Head, first joint of antennae, palpi, collar, coxae, femora, hind tibiae 

 and ventral surface of abdomen and thorax bright orange-yellow. Clasp- 

 ers of male and terminal part of body in female also orange-yellow. All 

 femora tipped with black, hind tibiae with black spurs and tip. Fore 

 and mid tibiae and all tarsi black. 



Primaries greenish drab in our one female, greenish black in males. 

 Secondaries dull brownish black. Thorax and abdomen above concolor-

 45 mm. 



Holotypc $ and two paratypes 9, White Mts.. Arizona. 

 Allotypc Huachuca Mts., Arizona. July 14. All in roll. Harm's. 

 All four types are in rather poor condition. 



Cisthene Walker. Logotype C. subjecta Wlk. 



The earliest valid type fixation for this genus which we are 

 able to find is that of Grote ( Mull. Buff. Soc. Nat. Sci. TT, 151, 

 1874). This was corroborated by Kirby in his Cat. Lep. Hrt. 

 I, 288, 1892. The name thus replaces Illlcc Walker as used at 

 present. 



Cisthene faustinula Bdv. 



The type of this species has recently been illustrated in 

 Oberthiir's Etudes. We have two Colorado specimens which 

 compare very well with this figure, but find that most of our 

 California: 1 , examples are referable to the form fnsca Stretch. 

 It would be interesting to hear from some of the Californian 

 students what conditions may govern the appearance of the 

 two forms. 



SUBFAMILY ARCTIINAE. 

 Arachnis midas n. sp. 



A single male .-Inn-Inns taken -by Mr. Tom Spalding at 

 Eureka. I'tah. August 24, 1920, proves to be an undescribed 

 species. 



This specimen is distinguished at once from most of our species by 

 its yellow secondaries, and from zuni Xeum. by the more brok.-n. 

 macular appearance of the dark markings of the primaries. These 

 wings are pure white, the markings almost identical with some speci- 

 mens of A. />/</</ nitiia Ottol. The secondaries are yellow of a more 

 ochreous shade than the secondaries of zutii, and the area between Ml 

 and .11 is semi-transparent yellow, not white as in emit $. Only tin- 

 fringes are whitish. There are three black dots on the outer margin,
