Dr. Dyar read his address as retiring presi- 

 dent, entitled ' Eeeent Work in Lepidoptera.' 

 The author stated that the classification of 

 Lepidoptera, ten years ago, stood essentially 

 as in the time of Linnaeus. During the past 

 few years, however, material changes have 

 had to be made as the relationships of families 

 and genera have come to be better understood. 

 The studies of Meyrick, Hampson, Chapman 

 and Tutt in England, and those of Comstock, 

 Packard, Kellogg, Bodine and the author in 

 America, have led them to adopt a eonunon 

 general scheme of classification, though differ- 

 ence of opinion still exists as to the details of 

 this scheme. The author reviewed briefly the 

 work of recent American lepidopterists. Tak- 

 ing up the butterflies, he compared the work of 

 Scudder and Edwards, mentioning also that 

 of French, Holland, Skinner and Beuten- 

 miiller. He then spoke of what has been done 

 in the different groups of moths — in the 

 Sphingidffi by Beutenmiiller and Packard, in 

 the Saturnians by Neumoegen and Dyar and 

 also by Packard, in the Noctuidse by Grote 

 and Smith, in the Notodontidse by Packard, 

 in the Geometridffi by Hulst, in the Pyralids by 

 Fernald, and in the Tineids by Lord Walsing- 

 ham and recently also by Dietz, Kearfott and 

 Busck. The author sunmied up by pointing 

 out the work particularly needed in the near 

 future, viz., a monograph of the butterflies, 

 comprehensive works on Sphingid and ISToctuid 

 larv£e, a monograph of the Geometridse, sup- 

 plementing and reviewing Dr. Hulst's work, 

 tables for determining the Tortricidse, and 

 continued descriptions of new species of 

 Tineids. 



Mr. Banks presented his ' Notes on Bra- 

 chynemuri of the B. ferox Group.' A crit- 

 ical study of large series of specimens hereto- 

 fore determined as belonging to the species 

 peregrinus, carrizonus, ferox and quadripunc- 

 tatus resulted in the discovery of three more 

 forms hitherto undescribed. Brachynemurus 

 peregrinus Hagen is considered a synonym of 

 B. ferox Walker. The author presented 

 descriptions, exhibiting specimens and a plate 

 of drawings showing the inter-antennal and 

 prothoracic markings and profile views of the 

 male anal appendages.

 one light were given the subject, who then 

 endeavored to reproduce the interval by taps
