252 ENTOMOLOGICAL NEWS. [October, 



same species I have also taken at Franconia this Summer. Two 

 of the Byrrhidae, B. geminatus and B. cyclophoruiif) were not 

 infrequent under stones near the stables, and with them I found 

 CryptohyPnus ventriculus and C. abbreviatus. Of course the 

 butterfly Chionobas semidea was there in numbers, flying about 

 among the rocks, darting down into dark crevices when pursued, 

 or resting on some gray, lichen-covered stone so like in prevail- 

 ing tint to its own mottled wings, as to defy detection. Of Ar- 

 gynnis montinus, the other and much rarer alpine butterfly, I saw 

 nothing on this first trip. Since the time, three or four years 

 ago, when I was so fortunate as to capture seven specimens 

 during the first week of August, I have never expected to find 

 them at an earlier date. 



THE MEETING OF THE ASSOCIATION OF ECONOMIC 

 ENTOMOLOGISTS. 



The fifth annual meeting of this Association, held at Madison, 

 Wis. , was in some respects the most successful that has been held. 

 In point of attendance it was behind the Washington and Ro- 

 chester meetings, but in the number and value of the papers 

 presented, it ranks with the best. As the proceedings are to be 

 published in detail in "Insect Life," and an abstract in the 

 " Canadian Entomologist," ii will be necessary to give here only 

 a mere outline of what was done, referring to the other publica- 

 tions for further information. The Presidential address by Prof. 

 S, A. Forbes was a thoughtful review of the work that had been 

 accomplished during the past year, and the plea for greater unity 

 of purpose among entomologists. 



Two papers were presented by Mr. J. Ritzema Bos, and were 

 read by the Secaetary, the writer not being present. M. H. Du 

 Buysson sent a paper on the use of Bisulphide of Carbon for the 

 destruction of insects, principally those infesting furs and Museum 

 specimens. The point of this article was in the description of a 

 water-joint to a box described by him, and in which the specimens 

 to be fumigated were to be placed. An interesting discussion 

 ensued on the uses of Bisulphide of Carbon both as a destroyer 

 of Museum pests, and of field insects. Quite a diversity of re- 

 sults appeared, and it is evident that this substance has not yet
