By Ralph V. Chamberlin, 

 Of the Museum of Comparative Zoology, Cambridge, Massachusetts. 



The descriptions and notes embraced in this article are based 

 chiefly upon material in the collections of the United States National 

 Museum. Occasion is taken to describe also some new forms in the 

 collection of the Museum of Comparative Zoology in Cambridge, 

 Massachusetts, and to illustrate several previously known species. 

 The characters of the male of Nannolene are made known for the 

 first time, the genus proving to be a member of the Cambalidae 

 proper.
