2lU THE CANADIAN ENTOMOLOGIST 



■'' ' The above like aestiva Fall, has tKe second antennal joint visible but very 

 small. 



Falli is more nearly like aestiva Fall, than any of the other species of this 

 geirius, but differs from it in its darker colour and smaller size; in having the 

 eyes more widely separated on the vertex and the upper lobe of the eye more 

 flattened; also in the possession of the punctured area on the occiput, and the 

 more evenly and broadly rounded outline of the lateral prothoracic profile. 

 In aestiva there is a pronounced tooth at the tip of the basal joint of the antennae 

 which is lacking in falli. Type in my own collection. 



I take pleasure in naming this species for my friend Mr. H. C. Fall, whose 

 help and kindness has been an inspiration in much of my entomological work. 



UROCERUS FLAVICORNIS, FABRICIUS. 

 This species, which is very similar to the European Urocerous gigas Linn., 

 ranges over all parts of Canada. There are the following records of its 

 occurrence, based for the most part upon the work of Bradley and Kirby. It 

 is found from Siberia and Alaska, south along the Pacific Coast to British 

 Columbia, Oregon and along the Rocky Mountains to Arizona and New 

 Mexico, and even Mexico; is unknown from California, and in Colorado, Utah, 

 Arizona and New Mexico is confined to high altitudes. The single record 

 from Nebraska is undoubtedly based upon an individual carried into the State 

 as a larva or pupa in lumber shipped from the Canadian or Hudsonian life 

 zone. This is not different from the record from England upon which 

 Stephens based his species, hizonatus. In the east this species extends south 

 from Keewatin through Labrador, Newfoundland, Nova Scotia, Northern New 

 York, New Hampshire and Massachusetts. Specimens have been reported 

 from the Adirondacks, Ithaca, White Mountains, and a small male from Con- 

 necticut. Provancher records the species from Canada, presumably Quebec. 

 In the central region it has been reported from Cape Krusenstern, Arctic 

 Regions, Fort Churchill, Hudson Bay, St. Martin's Falls, Albany River and 

 Mackenzie River. I am writing the above to bring the records of distribution 

 together and to record a specimen received from Mr. F. Johanscn, which was 

 collected by the Rev. I. O. Stringer along the Mackenzie River in 1896. This 

 specimen comes from the Royal Ontario Museum of Toronto. 



Alex. D. MacGillvray. 



"In the Royal Ontario Museum there are specimens of Urocerus flavcornis 

 also from Spruce Brook, Nfld.; Godbout, Que., and Edmonton, Alta. The 

 specimens from the last-named locality were taken by Mr. F'. S. Carr, the 

 others by the writer. The species was apparently common at Godbout, on 

 the ngrth shore of the lower St. Lawrence, near the Gulf.
