58 THE CANADIAN ENTOMOLOGIST. 



be published. He exhibited also a pair of primary royalties of Termopsis 

 angusticollis, the Pacific Coast Termite. He had found no difficulty in 

 securing a number of these royal pairs, and one of them he had brought 

 alive from California in some decaying wood. The true royalties of this 

 kind are certainly very rare, and these forms excited much interest. 



Mr. Kellogg followed with an account of his work with the Blepharo- 

 ceridse, a family of Diptera, which inhabit in the larval stage swift-running 

 mountain streams. These Diptera have hitherto been considered very 

 rare, and only fifteen species were known in the world — five of them in 

 North America and six European, the remainder subtropical or tropical. 

 To this number he had added four new species which he had studied in 

 all stages, and added much to the information of the early stages, which 

 had previously been little known. He described the manner of attach- 

 ment of the larvge to the rock beds in swift streams, the insect not oc- 

 curring in still water, and gave an account of the habits of the larvje, the 

 remarkable specialization in the larval and pupal characters, and also the 

 habits of the adults, together with some details of the structural peculiar- 

 ities of the latter. He urged all collectors to be on the lookout for these 

 curious insects. He reported that the results of his investigations were in 

 press, and included a revision of the family in North America, giving full 

 details of all his studies, and he promised to send this paper to any one 

 interested in the subject. A miscellaneous discussion followed this com- 

 munication, bearing on these Diptera, in which some additional facts and 

 explanations were given by Mr. Kellogg. Concluding the discussion, 

 Mr. Schwarz stated that he was not familiar with any matter contained in 

 the Entomologica Americana bearing on these insects, but that in com- 

 pany with his late friend, Mr. Hubbard, and also later with Mr. Barber, 

 he had made examinations covering two years in Arizona, and had never 

 found an example of Blepharocera. He believed this to result from the 

 fact that none of the mountain streams in Arizona can be called perma- 

 nent. Every other season, at least, these streams dry up. Both Mr. Hub- 

 bard and himself, he stated, were well acquainted with these forms, and 

 would have recognized them if they occurred there. The Simulium flies, 

 on the other hand, maintained themselves under the conditions noted ; in 

 other words, they were able to live in these streams and to survive the dry 

 period, by what means he was not able to discover. 



Dr. H(jpkins presented the following account of recent work in Forest-
