shown something of the same tendency in his first paper. The next 

 few years will certainly show marked advances in our knowledge 

 of the Tineids. 



This review indicates that we need certain work in the im 

 mediate future. A monograph of the Butterflies with practicable 

 sypnotic tables, critically revising both genera and species ; com 

 prehensive work on the larvae of the Sphingidas ; studies on the 

 larvae of the Noctuidse^to supplement Dr. Smith's work on the 

 adults, which should be continued ; a review of Dr. Hulst's 

 work on the Geometridae, which might most profitably take the 

 form of a monograph, giving practicable sypnotic tables to spe 

 cies to supplement Dr. Hulst's generic ones ; determinative 

 tables for Tortricidse, both generic and specific. Dr. Fernald 

 ought not to delay the preparation of such a badly needed paper ; 

 continued descriptions of new species of Tineids to make the 

 extent of our fauna known to us. We hope to see these subjects 

 soon taken up. , 



At the conclusion the society offered Dr. Dyar a vote of thanks 

 for his address. The address was discussed by Messrs. Schwarz, 

 Banks, Gill and Marlatt. 



Mr. Banks then presented the following paper : 



NOTES ON BRACHYNEMURI OF THE B. FEROX GROUP. 



(PLATE III.) 

 By NATHAN BANKS. 



In examining some recent additions to my collection of Myr- 

 meleonidae, I was struck more forcibly than ever before with the 

 constancy in size and shape of the male appendages. Various 

 species are now known to me from a considerable number of locali 

 ties, yet there is no distinct variation in the general appearance 

 of these appendages. Therefore it seems that they are of con 

 siderable importance in the separation of species. In the B. ferox 

 group I have had various specimens that differed from the known 

 forms very slightly in colorational points but prominently in the 

 appendages ; therefore I believe these forms are distinct species.
