exhibition of an inflated larva and two live pupae of the native 

 species. 



Mr. Kirkaldy exhibited three old entomological works which 

 he had recently purchased : there were Thomas Moufet's "Thea- 

 trum Insectorum," London, 1634; Swammerdam's "Historia In- 

 sectorum Generalis," 1693; and Frisch's "Beschreybung von aller- 

 ley Insecten in Teutschland," 1720-38. Considering their age, 

 every one present marvelled at the excellent state of preservation 

 of the prints and cuts. Dr. Cobb stated upon the authority of an 

 expert on paper that our modern half-tones, which are printed on- 

 paper so heavily chalked, will not last over fifty years. 



Mr. Kotinsky exhibited dipterous larvae in a tube ; into this 

 tube were originally deposited whatever larvae or pupae seemed 

 dead or dying selected from a lot sent by Mr. Koebele from Aus- 

 tralia. The object of the selection was to breed up some parasite 

 of these Diptera, but he was surprised to find some two or three 

 days later that the tube swarmed with live dipterous larvae, al- 

 though he had constantly kept the tube closed with a cotton plug. 

 Mr. Terry suggested that some Sarcophagid might have surrepti- 

 tiously inserted her ovipositor and dropped some eggs or larvae 

 into the tube. Dr. Cobb stated that he had observed several dozen 

 flies aboard ship all the way from San Francisco to Honolulu. 

 Mr. Bryan stated that during a cruise on a sailing vessel lasting 

 some two months, he had observed flies constantly upon it. 



The question raised by Mr. Kotinsky regarding the seasons 

 of these islands, as judged by the manifestations of life, elicited 

 an extensive discussion, participated in by Messrs. Bryan, Terry, 

 Kirkaldy, and Kotinsky. Mr. Bryan stated that, as a general rule, 

 birds upon these islands nest most commonly about the end of 

 February to the beginning of April, which leads him to believe 

 that our month of March corresponds in a way to May or June 

 in the temperate zones. It so happens that it rains very freely 

 during the nesting season, and many nests with eggs of young 

 are often drowned out. His belief is that it is not so much the 

 rainy weather or the food supply that afifects the season of nest- 

 ing as such climatic conditions as temperature, etc. He had one 

 nest of young of an owl (Asio accipitrinus subsp. sandwkensis) , 

 that is a sub-species very closely allied to the American type-form, 

 which was secured in November. Another nest of owls was
