JOHN HABBERTON states that mosquitoes are extremely frightened by 

 dragon flies and will not come within yards of them. He says that one 

 or Uvo dried dragonflies suspended from fine silk under the roof of an 

 open porch infested by mosquitoes will scare all of the little pests away, 

 and they will not come back while the dragonflies are there. This, he 

 says, he has tried with surprising results. It is a well-known fact that 

 dragonflies are predatory and voracious insects, and that they subsist 

 largely upon gnats, midges and mosquitoes, and it is but natural that the 

 mosquito, who is a wise insect, should regard the "spindle," "darning- 

 needle" or dragonfly, as the small bird regards the hawk. 



NOTE ON ANOPHTHALMUS. A large series (175 specimens) of these 

 interesting blind Carabids, collected in Mammoth Cave, Kentucky, by 

 R. Ellsworth Call and myself, were of four species, viz. :

Menetriesii is the most variable in size, and some specimens show 

 traces of pubescence. Each of these species is easily separated from the 

 others by the shape of the thorax. The type of audax was from Ronald- 

 son's Cave, Kentucky. It has the thorax wider than long and nearly as 

 wide at base as apex. It is a small species. This is, I believe, the first 

 record of the occurrence of audax in Mammoth- Cave. I searched the 

 caves in Carter County, Kentucky, viz.: "Bat," "X," "Laurel" and 

 "Saltpetre" Caves, but failed to find Anophthalmus in either of them.

THERE are at present 2864 volumes in the library of the American 

 Entomological Society, including in volumes of pamphlets averaging 

 fifteen titles to the volume. The various departments are represented as 

 follows: Journals, 1436; Coleoptera, 389; General Entomology, 341 ; Le- 

 pidoptera, 214; Economic Entomology, 122; Hymenoptera, 101 ; Dip- 

 tera, 86 ; Miscellaneous, 61 ; Hemiptera, 49 ; Orthoptera, 40 ; Neuroptera, 

 25. This represents an increase of nearly 100 per cent since 1888, when 

 the total number of volumes was 1445. 



In the library of the Academy of Natural Sciences of Philadelphia there 

 ire 1 22 1 volumes, exclusive of journals, and uSS pamphlets, devoted 

 entirely to Entomology. The pamphlets form 77 additional volumes. 



While the books of one library are partially duplicated by the other, 

 yet it is safe to say that the foremost collection of entomological books 

 in America is to be found in the building of the Academy of Natural 

 Sciences of Philadelphia, where both libraries are situated. \V. J. Fox.
