Under the above title it is intended to publish short studies, 

 either of species or small groups of genera, which may from 

 time to time be investigated in a detached and desultory 

 manner. Care will be taken, however, to indicate the rela- 

 tionships wherever possible and whenever these are at all 

 obscure, so that it is hoped no confusion will be introduced 

 into our already overburdened nomenclature. Large and 

 complicated genera, or those in which the species are very 

 closely allied and difficult of recognition, will not be touched 

 upon except under very peculiar conditions, as these should 

 form the subject-matter of separate essays. 



In this connection it may be stated that it is my intention 

 to include, if possible, within the faunal region considered, 

 the entire North American continent terminating on the 

 south in the isthmus of Panama and including the islands 

 of the West Indian archipelago, as this appears to consti- 

 tute a more natural region than that which is limited on the 

 south by the Mexican boundary of the United States. 



The present paper contains descriptions of new r genera and 

 species, mostly from the Pacific Coast, but with a few from
