tooth from this species does not emerge until tlie following June, 

 so that any one desiring to secure specimens will probably have no diffi- 

 culty in doing so next year by visiting Beech wood in that month. 



DiPTERA. — The study of this order in Canada is still exceedingly 

 difficult, owing to the lack of works dealing with the classification and 

 identification of species. Tliis, however, will be gradually remedied, as 

 several American entomologists are engaged in the work, and articles 

 are appearing from time to time on various groups. Specimens have 

 been taken by several of our collectors, and the species in their pof^ses- 

 sion are now fairly numerous, although but few of them have been, as 

 yet, identified. 



CoLEOPTERA. — Although this order has been well investigated in 

 past yeais, it has been found possible to add quite a number of species 

 to the extensive lists already existing, while additional specimens of 

 some of the rarer species have been captured. Among the.se may be 

 noticed Xylonjctes satijrus, a very laige beetle belonging to the Scara- 

 bpeidfe, of which a fine specimen was taken by Miss I. Grant, at a sub- 

 excursion to Beecliwood in September. A fine male of rUyobius 

 rfn(7uinu5, figured in Tran.sactions No. 1 under its synonym P. Billwgsii, 

 was captured by ]\Ir, Fletcher in his study one evening, it having been 

 attracted by the lamp. Foecilinota cyanipes, a beautiful Bui)restian, 

 was captured at a sub-excursion beyond Stewarton, on a poplar stump. 

 JJydrophilus triangularis, one of our largest water beetles, not before 

 captured by our members, was received from Mr. A. L. Jarvis, who 

 found it beneath an electric light. As soon as the species which remain 

 to be identified have been determined, a sup[)lementary list will be 

 piepared for publication. 



Hemiptera. — This order has not )et received much attention, but 

 as synojitic tables are now being published in Entomologica Americana, 

 and as Abbe Provancher is publishing descriptions of all Canadian 

 si)ecies, it will be possible for collectors to work at it advantageously. 

 The number of species known fiom this locality is, however, nearly 100. 



Neuroptera. — Mr. T. J. Maclaughlin has made extensive col- 

 lections in tliis order and part of his work will be s\ibmitted to the 

 Club later, in the shape of a paper on the dragon-flies of this locality.
