64. Thyinelicus ccrnes Bd-Lec. Our commonest skipper ; on the 

 wing from the very end of May till the middle of September almost 

 without interruption, but most abundant in June and the last half of 

 August, so it is likely that there are but two broods. 



65. Thymelicus alcina Skinner Identification somewhat uncertain; 

 several specimens ( $ ) collected in July, 1909, and referred to this 

 species; subsequently a series of alcina was collected in the western 

 part of the state and when placed side by side with the Omaha speci- 

 mens, differences were detected. Reference was then had to the 

 original description of alcina and the western specimens were found 

 to agree with it, leaving the identification of the Omaha specimens in 

 doubt. The differences, however, are not great. 



66. Politcs ficckius Kirby Another very common skipper ; flies with 

 ccrnes, the seasons being about the same, and like it appears to be 

 double-brooded. 



67. Eiiphycs rerun Edw. Not found prior to 1912 ; one specimen 

 taken July 3 and another July 5 of that year, in widely separated 

 localities. 



68. Eiiphycs rcstris Scud. Fairly common ; appears at the very end 

 of July and remains on the wing about three weeks ; sometimes found 

 also in early June, indicating probably two broods. Differs from var. 

 mctacomct, found in western part of the state, in being almost black. 



69. Lcrodca osyka Edw. A single specimen ( $ ) taken by Mr. F. 

 H. Marshall, Sept. 7, 1912, while collecting in company with the writer. 

 Identified by means of Dyar's "Review of the Hesperiidae of the U. 

 S." Specimen fresh and in perfect condition. 



70. Limochores pontiac Edw. -A single specimen ( $ ) taken Julj 

 9, IQIO. Specimen beautifully fresh, showing that this species was 

 just beginning to emerge ; unfortunately this locality a marsh area 

 has not since been visited at the right season of the year for ihis 

 species, and hence no further individuals have been taken or observed. 



71. Limochores dion Edw. While searching for pontiac on July 6, 

 1912, in the locality where the single specimen was found in 1910 

 (possibly a week too early), 5 specimens of dion (2 $ and 3 9 ) were 

 taken, all of them fresh and perfect. 



72. Phycanassa delau'are Edw. Apparently rare, as but three speci- 

 mens have been taken, 2 on July 24, 1909. and i on July 10, 1912. 



73. riiycanassa arogos Bd-Lec. Found in only one locality so far 

 a piece of virgin prairie land but quite abundant there. Flies during 



July. 



74. Epargyreus titynis Fab. Extremely common ; two broods, the 

 first appearing about June 10, the second about the middle of August. 



75. Thorybcs bathylus Sm-Abb. Common; found from May to Sep- 

 tember, no doubt double-brooded. 



76. Thorybcs pyladcs Scud. Common ; last half of June and early 

 part of July.
