originated above instead of below this older type and anyone 

 holding the contrary view must prove his case. 



Your argument about the Cycnodioidca is open to the same 

 defect." 



Mr. Busck said he prized highly the friendly criticism of an 

 authority like Mr. Meyrick, whose excellent work was the foun- 

 dation of the modern classification of the Microlepidoptera. 

 He was anxious to have these contrary views, privately com- 

 municated, made known, so as to get as fully elucidated as 

 possible the important principles underlying the concrete ex- 

 amples under discussion. He wished to present them without 

 comment at present, except for the statement that he still held 

 the opinions expressed in the above-mentioned paper and hoped 

 shortly to present additional evidence in substantiation of 

 them. 



Dr. Howard said that the two types of larva 1 found in the 

 genus, the flat and the round, were very distinct, and he 

 thought Mr. Busck's classification to be the more natural one. 



Dr. Dyar said that there was always danger in relying upon 

 any single character, however good in general, and he thought 

 that this might apply to the larvae in this instance. 



Mr. Busck, however, pointed out that the division of the 

 genus by the flat and round larvae was not founded upon a 

 single character, but was marked in all stages, even the adults 

 having a different pattern of coloration, as he had already- 

 shown. The venational difference relied upon by Miss Braun 

 and supported by Mr. Meyrick consisted only in the coal- 

 escence of veins already stalked, and is simply a character of 

 specialization, without fundamental importance. 



Mr. Schwarz assumed the chair and the President read a 

 paper on "Two New Aradidse."
