it has not been recorded in the Hterature of the louse. A similar body, 

 he said, always occurs in several groups of Homoptera that he had 

 studied. Its forerunner is present in the egg and is carried to the 

 interior at the time of invagination. In parthenogenetic forms its his- 

 tory is associated with the development of the ovaries. Buckner con- 

 sidered it a commensalistic organ, but this view is not held by all embry- 

 ologists. 



A. N. Caudell: Notes on Zoraptera. A discussion of the biology 

 and systematics of this peculiar group of insects. Points of particular 

 interest were the finding of winged forms by Mr. H. S. Barber and the 

 fact that the insects have the habit of dealation. 



G. C. Crampton: Phytogeny of Zoraptera. Presented by title. 



324TH MEETING 



The 324th regular meeting of the Society was held October 2, 1919, 

 in the auditorium of the Cosmos Club. Vice-President Gahan presided 

 and there were present twenty-three members and six visitors. 



The following program was given : 



Harry F. Dietz: Notes on the insect fauna of Panama. 



This was an account of Mr. DiETz's observations in the canal zone, 

 especially on the scale-insects Aleur acanthus woglumi and Coccus viridis, 

 and on termites of various species. The talk was copiously illustrated 

 by lantern slides. 



In the discussion of this paper Mr. Schwarz spoke of the entomologi- 

 cal exploration of the Canal Zone, especially of that by Motschulsky 

 and Leconte and the collaborators of the Biologia Centrali-Americana, 

 as well as the more recent Smithsonian Expedition including Messrs. 

 Schwarz and Busck. 



H. F. Wickham: Two new Carabidae from Alaska. 



In presenting this paper Mr. Schwarz spoke of the knowledge of the 

 Coleoptera of Alaska, dwelling more especially on the collections made 

 by Dr. Eschscholtz and those made under the guidance of Count von 

 Mannerheim. He pointed out that all the early explorations were on 

 the southern coast of Alaska including the islands of the Bering Sea. 

 The two species of Tachypus described in Prof. Wickham's papers were 

 collected in the interior, where the fauna is radically different from that 

 of the coast region. Mr. Schwarz also gave a short account of Mot- 

 schulsky's trip to North America as published by that author in his 

 letters to Menetriez. 



Dr. Howard introduced Dr. S. I. Kuwana, the famous Japanese 

 entomologist, who addressed the Society briefly in Japanese and in 

 English in appreciation of his trip about the United States in search 

 of entomological methods and ideas. 



Notes and Exhibition of Specimens 



Dr. Aldrich spoke of the problem in distribution offered by the 

 Ephydrid fly, Lipochaeta slossonae Coq. This fly lives along the margin 

 of the Atlantic Ocean from New Jersey southward and along the Gulf 

 coast, reappearing at Long Beach in Southern California. He did not 

 know whether it occurs around the coast of South America or if its 

 distribution is discontinuous.
