Type Apterous $ , Yampa River, N. W. Colorado, August 

 20, 1920; allotype, same data; paratypes, 2 males and 5 females, 

 same data. R. C. Moore, collector. Type, allotype, 1 male and 

 4 female paratypes, in collection of University of Kansas ; 1 

 male and 1 female para type in my collection. 



Described under binocular microscope, with 55 mm. objective 

 and xlO eyepiece, and 24 mm. eyepiece for pubescence and 

 finer details. Eyepiece micrometer ruled to .001 mm. used for 

 proportions. 



This species seems to belong in the monotypic genus Trc- 

 pobatopsis, described by Champion from a single mutilated 

 apterous male from Mexico (Salic). The female and the 

 winged of both sexes of dcnticornls Champ, are still to be de- 

 scribed. The absence of the antennal joints and tarsi, however, 

 forbids certainty as to the genus to which our species is to be 

 attributed, but if it represents another genus, it is probably a 

 new one, close akin to Trcpobatopsis. 



This species differs generically from Trepobatcs Uhler in the 

 size and proportions of the head ; proportion of first two anten- 

 nal joints ; pronotal proportions, and structure of abdomen. 

 The color and the proportions of the leg segments and the ab- 

 sence of teeth on the anterior femora and the intermediate tibia 

 at once separate it from Trepobatopsis denticornis Champ. 



Atrytone kumskaka Scudder (Lep., Rhop.). 



By HENRY SKINNER. 



This Hesperid has been under discussion for a number of 

 years and has not been positively identified. Specimens taken 

 in Iowa were referred to conspicua Edwards by Dr. Scudder. 

 Discovering his mistake in 1887, he named the species kninskaka 

 and gave a full description of it and figured the abdominal ap- 

 pendages of the male. It was described from two males and 

 three females from the "Western States." According to the 

 description of kumskaka (consplcna nee Edwards) in the 

 Transactions of The Chicago Academy of Sciences, two males 

 and a female were taken by J. A. Allen, at Den i son, Iowa, in 

 July, on Rchinacca anyustifolia D. C., a plant growing on grassy 

 knolls of the open prairie. Mr. Nathan Banks has very kindly
