Under the head of 4t Short Notes and Exhibition of Specimens," 

 Mr. Schwarz spoke of the collection of insects recently made by 

 Henry G. Hubbard in southern Arizona. This collection is 

 altogether the most extensive and valuable which has been made 

 in that part of the country. In Coleoptera alone he estimates 

 that there are between 300 and 400 species new to the fauna of 

 the United States. He spoke at some length about the previous 

 collections, by Drs. LeConte and Horn, by the Government sur 

 veys, by Morrison, and by Wickham. Morrison's sets, when 

 sent abroad, were usually labelled " Sonora," and have thus been 

 included in the Biologia-Ccntrali Americana. When sent to 

 American workers, however, they are labelled u Arizona." They 

 were probably all made, however, in the Graham Mountains, 

 near Ft. Grant, and above Ft. Huachuca. 



Mr. Schwarz exhibited a specimen of the Scarabaeid Lissome- 

 las fiohri Bates, a genus new to the United States, and allied to 

 Cremastochilus. The specimens collected by Mr. Hubbard at 

 Ft. Grant, Ar., however, were not found in ants' nests, but under 

 old leaves, nor could any traces be found of thoracic glands, which 

 are supposed to be attractive to ants. He spoke of the velvet-like 

 coating on the rear half of the elytra, and said that in the speci 

 mens collected it was badly scratched, possibly by ants. He 

 further generalized as to the Arizona fauna, stating that we do 

 not know its Mexican limits, and remarked upon the great varia 

 tion between the faunas of the valleys and of the mountains. 



Mr. Fernow thought that this great difference was due entirely
