4 BULLETIN 15 7, U. S. NATIONAL MUSEUM 



The personal investigations upon which the present memoir pri- 

 marily is based have yielded a total of 85 species from the District 

 and immediately adjacent territory, of which the following 10 

 seem not to have been previously taken here : 



Chlorippe clyton. 

 Phyciodes hatesii. 

 Brent his myrina. 

 Argynnis aphrodite. 

 Incisalia henrici. 



Erynnis sassacus. 

 Atrytone logan. 

 Atrytone pontiac. 

 Atrytonopsis hiamut. 

 Poanes massasoit. 



The discovery of three of these {Brenthis myrina^ Atrytone pon- 

 tiac, and Poanes massasoit) was due to the kindness of Herbert S. 

 Barber, who pointed out to me a bog strikingly similar to the bogs in 

 eastern Massachusetts wherein I later found them. 



The 7 species known from the District that I have not been able 

 to find are : 



Cecroptenis cellus. 

 Poanes viator. 

 Calpodes ethlius. 



Polygonia progne. 

 Libythea bachmanii. 

 Strymon Ontario. 

 Incisalia inis. 



Harold H. Shepard, of the Bureau of Entomology, has been so 

 kind as to give me a list of the skippers (Hesperiidae) that he has 

 found in the District and in adjacent portions of Maryland. Those 

 from the District are : 



Epargyreus tityrus 

 Thorybes pylades. 

 Pyrgus tessellatus. 

 Pholisora catullus. 

 Thanaos icelus. 

 Thanaos persius. 

 Thanaos juvenalis. 



Ancyloxypha numitor. 

 f Erynnis sassacus. 

 Hylephila phylaeus. 

 Pontes coras. 

 Pontes vema. 

 Pontes cemes. 

 Atalopedes campestris. 



On the eastern shore of Maryland Mr. Shepard has taken in 

 addition Megistias fusca and Poanes aaroni, as well as Incisalia 

 augustinus. 



One species that has not been found by Mr. Schonborn, Mr. Shoe- 

 maker, or myself is represented in the National Museum collection. 

 This is the large and striking canna skipper {Calpodes ethlim), of 

 which the museum contains five specimens collected by A. B. Duckett 

 and the late F. H. Chittenden in Washington. 



The United States National Museum, possessing the Schonborn 

 collection and my collection, as well as many specimens presented 

 from time to time by local entomologists, contains representatives of 

 all the species known from the District with but two exceptions. 

 These are Strymon ontaHo Ontario, of which there is one District 

 specimen in the American Museum of Natural History, New York 

 City, and another in the collection of Ernest Shoemaker, in Brook-
