106 THE CANADIAN ENTOMOLOGIST. 



includes ten species. There should be at least fifteen. G. ahbreviatus 



Selys, fratcrnus (Say), vastus Walsh, descriptiis Banks, OpJiiogomphus 



colubr'uius Selys, and LantJitis parvulus Selys, are all probably 



residents. The writer has never collected in a good Gomphine locality 



at the proper season. Leucorhi?iia should furnish one or two more 



species in the north, such as Z. Hiidsonica (Selys) and proxima Hagen, 



while Argia ought to be better represented in the south, A. tibialis 



(Ramb) and sedula (Hagen) being not unlikely to occur in the Upper 



Austral Zone along Lake Erie. Of other Zygopterous species, Hetcerifia 



Avierica7ia (F.), AwpkiagrioJi saiicium (Burm.), Aiiomalagrion hastatiim 



(Say), and Ischnura posita (Hag.), are almost sure to turn up in the same 



zone, if not further north. 



The writer acknowledges with gratitude the kind assistance of Drs. 



J. G. Needham and P. P. Calvert in the determination of many 



specimens. 



Sub-order ZYGOPTERA. 



Family Calopterygid^. 



1. Calopteryx maciilata^ Beauv. — Hamilton, June; Toronto, June 

 22-July; Berlin, July-Aug., (W. J. Eraser); De Grassi Pt., Lake 

 Simcoe, July 6-Aug.; Algonquin Park, Juiy-x\ug ; Thessalon, Algoma. 



An abundant species along the banks of woodland streams. 



2. Calopteryx a^qiiabilis, Say. — Berlin, july-Aug., abundant (\V. J. 

 Eraser); London; Algonquin Park, July 25, 1900, Aug. 31, 1902; 

 Thessalon, Algoma ; Michipicolen, L. Superior (Hagen, C. Hiidsoiiica). 

 The dark patch at the apex of the fore wings is broader and more sharply 

 defined in the specimens from Algonquin Park than in those from Berlin. 

 The only female I hcive seen is the single example from Thessalon, in 

 which the wings are only just perceptibly deeper at apex than elsewhere. 



Family Agrionid^. 

 Sub-family Lestiiice. 



3. Lestes congener^ %z.y. — Niagara Glen, Aug. 18, 1904; Algonquin 

 Park, Aug. 14-29, i902-'o4, abundant. 



4. testes tinguiculata, Say. — Ciiathain, Aug. 10, 1901 ; Sarnia, Aug. 

 12, 1901; Berlin (\V. J. Eraser): Waljjole Id., River St. Clair, Aug. 13, 

 1901 ; Point Pelee, Aug. 8, 1901 ; Thessalon, Algoma ; Toronto, July 6, 

 1904; Ue Grassi Pt., July 7, 1901. A common species. 



5. Lestes uncata, Kirby. — Hamilton (Anderson, Biol. Dept., 

 Toronto); loronto, June 15-July 6; De Grassi Pt., Aug.; Algonquin 

 Park, Aug. 13, 1903. A scarce species wherever I have taken it.
