48 THE REPORT OF THE No. 19 



on which the notes are recorded — January Februaly March could be put together,a8 reference^ 

 would likely be few. A card for each day on which anything is noted is inserted in its place 

 according to date. This makes a very compact record of the year's captures, and additional 

 notes on species observed by fellow collectors, which one hea'S about a week or more later, 

 can be dropped into their proper place in a manner quite impossible in any book. To cross 

 index this the alphabetical index is required. Let us say a trip to Quebec is taken August 21st 

 to 24th, 1902. Separate cards mentioning each day's notes are put in place in the diary behind 

 the August card and in the alphabetical index a card is inserted, behind letter "Q", headed 

 Quebec. : "'Spent a few days at Quebec Aug. 21-24 1902." On the Quebec card would also be 

 noted references to published papers on insects found at Quebec, etc. 



If a species of interest is taken, say Pamphila Manitoba, a card headed with the name of 

 that species is marked " 1 specimen Island of Orleans, Quebec, 2l-viii-02, on everlasting 

 flowers, A. F. VV." All further original notes, or references to published matter are put on this 

 card till filled, when a second card may be used. To find the cards quickly, they are arranged 

 alphabetically behind a genus card whose name shows at the top, and the genera are arranged 

 in families in the same order according to some List. Perhaps it would be more consistent to 

 arrange the genera alphabetically also, but it seems easier to look for Grapta next to Vanessa 

 than to woik alphabetically. When a new List appears, and the names get changed around,^ 

 a few cards will have to be inserted here and there indicating that the genus Ilepialus has been 

 transferred to the Micros or elsewhere, or that some genus has been divided into a dozen or so. 

 The alphabetical index could be used as a sort of directory. 



For life-history work the cards seems specially useful, as an unlimited number of cards 

 may be used numbered consecutively, keeping track of egg, various stages of larva, chrysalis 

 and imago. If a sta.e or more is missecl one season, the informacion can possibly be obtained 

 another year and another card inserted in its proper place. 



ADDITIONS TO THE SYRPHIDAE OF THE PROVINCE OF QUEBEC. 

 By Gustave Chagnon, Montreal. 



Since the publication in 1901 of my ''Studies on Canadian Syrphidae " in which were 

 described about 90 species of these flies, more material was collected and carefully examined. 

 Amongst this material, some of which was collected by Mr. Stevenson, of Montreal, and Abbe- 

 Roy, of Levis, were found several important additions to my list. The following is a brief 

 account of these additions. 



Criorhina armillata, O.S. One 9 specimen was captured at Piedmont, on 7th June, lf)02, 

 by Mr. Charles Stevenson. This species is quite difi"erent from those already given in my 

 "Studies" by its black abdomen and by the anterior cross vein which is nearly rectangular 

 and placed slightly before the middle of the discal cell. 



This species was described by Osten Sacken in 1878, from one 9 specimen taken at 

 Quebec. Its geographical distribution seems to be northern as I cannot learn of its capture in 

 the United States. 



Merodon equestris, Fabr. Taken at Outremont, on 7th July, 1901. This specimen is 

 doubly interesting as being perhaps the only capture in the new world of a species belonging 

 to an European genus of which no representatives have been recorded in North American lists. 

 It is closely allied to Eris'alis by its front being evenly arched and the third longitudinal vein 

 being strongly bent into the first posterior cell. 



Fipiza nigripilosa. Will. This species is easily separated from the others by having a 

 ong black pilosity on its body. It was captured by myself at Sherbrooke, on 30th May, 1902, 

 while collecting with Abbe Begin of that place.
