oaks which replace in part the deciduous oaks of the north. For each of 

 the places visited he mentioned the features affecting the insect life, the dense 

 growth of live oak and bayberry on Anastasia Island, and the wash-up on its 

 beach, the sand dvines, moist meadows and wild flowers back of the beach ; 

 the great arc lights at Daytona making good evening collecting there as well 

 as the varied swamps and pine woods back of the town ; the great plenty of 

 insect life among the varied subtropical vegetation at Palm Beach and Miami, 

 especially upon the blossoms of the pawpaw in the subtropical swamps across 

 the Miami River ; the excellent collecting to be found in the suburbs of Key 

 West and Tampa, quickly reached by trolley, and in the cypress swamp near 

 Ocala easily penetrated by reason of an old railroad track. Mr. Engelhardt 

 exhibited a selection of the Lepidoptera caught during his journey divided to 

 show the differences between the northern half of the state where forests of 

 long leaf, yellow and scrub pine are found, and where northern trees like 

 sweetgum, sourgum and tulip still occur, the region subject to killing frost 

 as far as oranges are concerned ; and the southern half of the state including 

 only species which were not found in the northern half, this southern half 

 being characterized by the absence of Spanish moss and the presence of intro- 

 duced subtropical plants and broader leaved epiphytes. He called attention to 

 the effect produced in some species by a continuous food supply, a continuous 

 development apparently resulting therefrom. For instance the larva of Artace 

 punctistriga was found on live oak trunk and developed into imago within 

 five days, and in the case of Liininetis larvae the hibernaculum usual in the 

 north was absent. In other cases, however, while no true hibernating stage 

 can be alleged, there is a quiescent or resting season. Thus a chrysalis of 

 Papilio cresphontes is still unhatched and larvae of Limacodidce are still un- 

 changed. There may be a connection between the differences observed in the 

 behavior of these insects and the abundance of certain butterflies compared 

 with the seasonal absence of others. The influence of climate and continuous 

 food supply needs further study to elucidate the problems suggested. Mr. 

 Engelhardt spoke also of the effect of cooler mornings in making the insect 

 take refuge among the leaves of trees and bushes by which the beating and 

 sweeping became more productive at such seasons. Owing to the lateness 

 of hour he did not comment on the individual species captured, of which a 

 list will be published later. 



Mr. Grossbeck showed the Lepidoptera collected in Florida during the 

 same month by Dr. Lutz and Mr. Leng. He pointed out as specially inter- 

 esting the Geometer G'ena texanaria taken by Dr. Lutz and speaking of the 

 Geometers taken by Mr. Engelhardt said that Stenotrachelys approximaria, 

 Synelys timandrata and 5". subquadrata were especially rare, each being pre- 

 viously known by one or two specimens outside the type. 



Mr. Davis exhibited thirty-eight species of Florida butterflies which he ob- 

 tained during the same month of November at Jacksonville, Lakeland and 

 Punta Gorda. Twenty-three of them belonged to species more or less com- 

 mon in the vicinity of New York or in New Jersey, while fifteen species were
