ous parasites with wings reduced to thread-like appendages. Speci-

]\rr. C. AV. Johnson spoke of the female of the rare fly Glutops 

 singularis, and made some additions and corrections to his notice 

 of this species in the December Psyche. 



Mr. L. E. Keynolds and several other members discussed the 

 recently published list of American Coleoptera by C. W. Leng. 



At the meeting of March S, l\lr. \i. E. Eeynolds read a paper on 

 zoological nomenclature, which was discussed by Messrs. Banks, 

 Frost, Howe and Johnson. The discussion dealt mainly with the 

 difficulties of the subject and led to no practical plans for improve- 

 ment. 



At the meeting of April 12, several designs for a club seal were 

 shown. 



Mr. Eoland Hussey read a ])aper on "Hibernation of Aquatic 

 Hemiptera." After a review of hibernation in general, Mr. Hus- 

 sey told about his observations at a pond near ^Minneapolis, where 

 he watched large numl)ers of CorixidsT? which, as the cold weather 

 came on, collected in the part of the pond where there was most 

 vegetation, in some places on October 29, as closely as 150 to a 

 square foot under two inches of ice. In January, under ice eight 

 inches thick, there were but few in motion, and in February none, 

 all being torpid at the bottom. 



January 15, under ice two feet thick, a species of Cyinata was 

 found hibernating, entirely torpid, in air bubbles in the ice, with- 

 out the insects themselves being frozen. Mr. Hussey started to 

 investigate this curious method of hibernation, but was taken sick 

 and obliged to give it up for tlie season, and the next winter 

 conditions were unfavorable for continuing the study. 



^h\ Gove showed a tal)le whicli he had prepared of the eleva- 

 tions at which he had collected butterflies, showing that each species 

 habitually flies at certain heights above the general level of the 

 country. 



j\[r. C. A. Frost spoke of tlie recent collections of Coleoptera by 

 Mrs. Hippisley, at Terrace, B. C, Canada, a newly settled country 

 within a hundred miles of the Pacilic Coast.
