BUTTERFLIES OF THE DISTRICT OF COLUMBIA 6 



Mr. Schonborn's collection contains representatives of 67 species 

 from the District. In most cases there are from one to four carefully 

 selected specimens, in a few cases more. 



One species, Polygonia progne, is known from the District only 

 through representation in this collection. Otto Lugger's specimen 

 of Vanessa j-olbum from Baltimore is also included in it. 



Other specimens worthy of special note are two bright, clear-yellow 

 males of Eureina 7iicippe and an unusually large female of Antho- 

 chaHs genutia with the tips of the wings yellowish and having more 

 black than usual, which suggests an approach to the related Antho- 

 charis scolymus of Japan and central and western China. I suspect 

 that the latter is a raised specimen. 



There is a single broken male of the orange clover {Colias 

 eurytheme), which is clear evidence that Mr. Schonborn knew this 

 only as a rare insect. None of the five specimens of the azure hair- 

 streak {Strymon m-aJhum) is perfect, indicating that he found this 

 also rare. There are only two specimens of Pleris protodice and two 

 of Pyrgus centaureae. 



The 15 butterflies in the Schonborn collection that are accompanied 

 by pupae or by pupal skins are : 



Basilarchia arthemls astyanax. 

 Basilarchia archippus. 

 Junonia lavinia coenia. 

 Pyram eis mrginiensis. 

 Vanessa antiopa. 

 Polygonia interroga tionis. 

 Eupliydryas phaeton. 

 Argynnis cybele. 



Ernest Shoemaker's collection, the result of nearly 50 years' col- 

 lecting in the District, is as interesting as that of Mr. Schonborn. 

 It includes 63 species, four less than Mr. Schonborn's. But all ex- 

 cept two of the species present in the Schonborn but absent from 

 the Shoemaker collection are common forms of no special significance. 



The 12 species present in the Schonborn but absent from the Shoe- 

 maker collection are : 



Feniseca tarquinlus. 

 AntJiOcharis genutia. 

 Papilio phUenor. 

 Pajnlio crespliontes.
