scutelluni, the remainder siibquadrate scutellum, those of Hispaniola only 

 forming crests apically from the clytral costs, those of other islands more 

 feebly developed in that respect. Some African Lycidse with subhumeral 

 spines were also shown. The peculiar abdominal structures were also ex- 

 hibited in enlarged drawings made by Mr. Olsen and were discussed by Dr. 

 Bequaert and Mr. Schaeffer, both of whom disclaimed any knowledge of 

 homologous structures, and by Dr. Lutz, who said that search of the litera- 

 ture had so far failed to disclose anything similar. Dr. Bequaert said they 

 might possibly be scent organs and Mr. Davis called attention to certain 

 auricular appendages in male dragonflies as being distantly similar. 



Mr. Schaeffer exhibited all the known species of Amblychelia of the United 

 States reviewing the previous disputes respecting certain forms and giving as 

 his opinion the following list of species, varieties and synonyms : 



A. cylindriformis Say. 



ssp. piccolomini Reiche. 



A. baroni Rivers. 

 enodis Casey, 

 var. longipes Casey. 



A. schwarzi W. Horn. 



Mr. Schaeffer also recorded the following additions to the known distribu- 

 tion of Cicindelidc-e, viz. : Cicindela striga, St. Petersburg, Fla., collected at 

 light by Mr. J. Doll. Cicmdela deccmnotata, Alaska, received from Mr. B. 

 Preston Clark, and spoke of specimens of Cicindela arisoncc taken at the type 

 locality by Mr. Englehardt and of Cicindela parozvaua found by Mr. Engel- 

 liardt at a new locality in Utah. 



His remarks were discussed by Mr. Harris and by Dr. Bequaert. On 

 reference to Merriam's favinal map it appeared that Amblycheila cylindriformis 

 -was confined to Sonoran regions, while the other species occurred in the 

 higher Transition regions or near their junction with the Sonoran. Dr. 

 Bequaert mentioned finding one specimen at light in July and another after 

 rain, but could not corroborate their abundance. 



Mr. Barber read a paper on " Some Hemiptera from the Adirondack Mts. 

 collected by Mr. Notman," exhibiting a collection of 56 species of Heteroptera 

 from Keene Valley, Essex Co., N. Y. He mentioned the thoughtful generosity 

 of Mr. Notman in giving his time and attention to further the knowledge of 

 the distribution of insects of the State other than the Coleoptera, in which He 

 was especially interested. Comparison of the number of species was made 

 with the number of species listed in Smith's New Jersey List (409) and in 

 Parshley's List of New England (419)- Reference was also made to the 

 various lists of Hemiptera of similar regions in the northern United States. 

 Mr. Barber referred to the comment of Dr. Wm. L. Bray in the " Develop- 

 ment of the Vegetation of New York State," 1915, on the character and origin 

 of the flora and insect fauna of Keene Valley in the Adirondacks. Though 

 in the main the hemiptera fauna belonged to the Canadian Transition, the
