1911] Hypera and Phytonomus in America 433 



The declivity of the elytra is extremely prominent and extends 

 quite to the tip. The scales beneath the elytra on the abdomen are 

 sparse except for a dense fringe on each segment posteriorly. 



Distribution: (See Map 7). Type: U. S. N. M., Nan- 

 tucket Id. 



Massachusetts: Nantucket Island (U. S. N. M., Field Col. 

 Mus., Bolter Coll. Univ. of 111.); Edgartown Martha's Vine- 

 yard Id. vi-27-10 Johnson (Coll. Bost. Soc. Nat, Hist.); 

 Chatham, vii-14-07 (Coll. Frost). 



The Nantucket Island specimens are, I believe, all from the 

 same lot and were probably collected by H. Soltau. They 

 have stood in the various collections under the name of 

 Phytonomus rumicis L. They, however, do not belong to this 

 group of the genus. One of the specimens is marked collected 

 on vetch, and another specimen "on Vicia sativa." 



Superficially the species resembles P. murinis Fab. more 

 than P. trivittatus Say but it belongs in the group with the 

 latter species.
