OF WASHINGTON. 49 



(I? OCTOBER 8, 1896. 



Vice-President Gill in the chair and Messrs. Schwarz, Hub- 

 bard, Ashmead, Mann, Benton, Heidemann, Pratt, Johnson, 

 Motter, Howard, Fernow, Ulke, and C. R. Linfoot also present. 



The Chairman announced the death, on August 9th, of Mr. 

 Henry F. Schoenborn, who had been a member of the Society 

 for something more than a year. He said that Mr. Schoenborn 

 had been a resident of Washington for more than 40 years, and 

 that he possessed the largest private collection of Lepidoptera in 

 the city. He paid a tribute to Mr. Schoenborn's excellent quali 

 ties as a man, and especially to his generosity as a collector. 

 His knowledge of local forms in the Lepidoptera was probably 

 greater than that of any other Washington entomologist. 



Under the head of "Exhibition of Specimens," Mr. Ash- 

 mead showed a female Thynnid, which he had found in the 

 National Museum collection labelled "Alameda County, Cali 

 fornia," by Koebele. This is the first North American species 

 of this family, with the exception of a male recorded by Patton, 

 also from California. Mr. Ashmead's specimen will form the 

 type of a new genus resembling the South American form 

 Aleurus. He will call it Glyptometo-pa americana. 



Mr. Howard suggested that both Mr. Ashmead's specimen 

 and that mentioned by Patton were possibly imported individuals 

 from either Australia or South America, in which suggestion 

 Mr. Schwarz agreed, stating that both specimens were taken 

 shortly after Mr. Koebele's return from successful trips to Aus 

 tralia. 



Dr. Gill spoke of the former connection between the Austra 

 lian, African, and South American continents, and of the 

 hitherto known distribution of the Thynnidas as dependent upon 

 this former connection. He thought that the fact that the new 

 genus belongs to the South American type is confirmatory of 

 the idea that it is a native form and that we have simply an in 

 stance of the northward extension of the range of the family. 



Mr. Heidemann exhibited a drawing of the winged male of 

 Rheumatobates rileyi, showing that the description of the
