rusty red color. The log and roots were honeycombed by several 

 species of ants. I worked May ijth, ipth and 22nd crumbling and 

 sifting this log; every inch of it was worked over. I found it a verit- 

 able mine of coleopterous treasures. I took more than 300 beetle-- 

 from it, a number of which are new to me. It was swarming with 

 Psfliiphidni\ Scydinucnidae and Trichopterygidae. Maj. Casey has de- 

 scribed three species of these Pselaphidae in Can. Ent., August, '08. 

 Many of these beetles were exceedingly minute, such as oprcssus, 

 lutcus Csy. and Leptoplectus exilissimus Csy. being the smallest of 

 their respective families. The little Tenebrionid, Dioedus pnnctatits 

 Lee. was in numbers, those freshly hatched being pale, while the ma- 

 ture ones were jet black. This species can generally be found in red 

 rotten wood. I collected only the coleoptera, though other orders were 

 numerously represented. The proper conditions as to season, degree 

 of moisture and food were present in this log, a combination of condi- 

 tions not always to be had together. When a collector finds such a 

 favorable combination, the locality should be worked until exhausted. 

 In the language of the Hoosier schoolmaster, "While your gittin', git 

 a plenty." In a locality that has been so thoroughly gleaned as Cincin- 

 nati, it is only by patient search for the small forms that new species 

 can be found. CHARLES DURY. 



DEALS DEATH TO THE FLY. French Surgeon Has Preparation That 

 Is Terrible and Certain. Doctor Delamarre, an eminent army sur- 

 geon, has just published the result of his investigations concerning the 

 contagion-bearing qualities of the ordinary housefly. Without hesita- 

 tion he condemns that familiar insect to death. He points out that 

 numerous plans for executing this sentence have been evolved by 

 scientists of all times and every country, but flies are apparently as 

 numerous as ever. 



He suggests a mixture composed of one part formol to nine parts of 

 water. This may be put in ordinary plates, and placed wherever flies 

 are likely to congregate. Twenty-four hours later, says the doctor, 

 not only the plates themselves, but a considerable space around them, 

 will be covered by flies and mosquitoes which the mixture and emana- 

 tions from the mixture have poisoned. The insects are attracted by 

 the solution as though it were sugar. To be perfectly effective it should 

 be changed every twenty-four hours. Newspaper. 



Doings of Societies. 



PHILADELPHIA, June ijth, 1908. 



At the meeting of the Feldman Collecting Social, held at the 

 resilience of Mr. II. W. Wenzel, fifteen members were present. 



A letter from Professor Philip P. Calvert was read, in which 

 he stated that he had examined the scale insects exhibited at 

 our last meeting, and found them to be the San Jose scale ; 

 slides were also shown.
