﻿DESCRIPTIONS OF NEW GENERA AND SPECIES OF 



MICROLEPIDOPTERA FROM PANAMA 1 



By AUGUST BUSCK 



(With One Plate) 



The following decriptions of new forms of Microlepidoptera are 

 published in advance of proposed papers, dealing with the lepidop- 

 terous fauna of Panama as a whole, based on material collected by 

 the writer as a member of the Smithsonian Biological Survey of the 

 Panama Canal Zone during the first half of the year 191 1. 



Two causes were operative in making the present paper merely 

 preliminary: first, the prospect of obtaining additional material 

 through another trip to Panama by the author in 19 12 in continua- 

 tion of the work done in 191 1 ; secondly, the delay in the publica- 

 tion of Lord Walsingham's part of the Biologia Centrali-Americana, 

 the completion of which now seems assured within a few months, 

 for it was desirable that the priority of no part of this important 

 work should be interfered with, and in the present paper no species 

 is therefore knowingly described which is already dealt with in the 

 remaining manuscript of the Biologia, with which the writer is inti- 

 mately acquainted. 



Family COSMOPTERYGIDyE 



The name Cosmopterygidse is used here in the same sense as em- 

 ployed by Meyrick, Trans. Ent Soc. London, 1909, p. 17, for the 

 family, defined by the writer in Proc. Wash. Ent. Soc, Vol. 11, p. 

 93, 1909, and for which I at that time accepted the name Lavernidse, 

 Walsingham and Durrant. 



Mr. Meyrick's name and definition of the family were the first to 

 appear together in print, and as the conception Lavernidae has already 

 been obscured by the admission of several alien genera in the 

 Biologia Centrali-Americana, I adopt the more willingly the name 

 Cosmopterygidse as the one least likely to cause misunderstanding. 



The essential characters of this group are as pointed out (1. c), 

 the long recurved and pointed labial palpi and the stalked (or coin- 



1 The present paper is the eighth dealing with the results of the Smithsonian 

 Biological Survey of the Panama Canal Zone.
