68 THE CANADIAN ENTOMOLOGIST. 



3rd November in the decaying wood of a fallen trunk, where a piece had 

 , previously been broken out of it. It is likely to have been bred in the 

 wood. Have taken numbers here under bark of dead oak. 



Stenoscelis brevis Boh. Three specimens (one immature, being very 

 light with only a slight tinge of color), taken 17th October in two small 

 upright trunks, in their little cells in the dead and rotten wood, upon 

 vvhich they had without doubt fed in the larva state, and there changed 

 afterward to perfect beetles. 



Cratoparis lunatui Fab. Three specimens, two taken 13th October 

 and one 17th October, in same trunks as preceding, under the loose bark 

 but near some small holes in the wood, from which it is very probable 

 they had lately emerged. I am inclined to the opinion that they had 

 passed their larva state in the trunks, feeding on the decaying wood. 



NOTES ON HYMENOPTERA, COLLECTED NEAR OTTAWA. 



BY J. A. GUIGNARD, OTTAWA. 



Within the first year of work in this branch of entomology in the 

 Ottawa district, I was able to make acquaintance with all the 26 orders 

 into which Hymenoptera are divided in Mr. Brodie's Canadian list ; and 

 now at the end of our second year, out of 247 genera, only about 70 

 remain unrepresented, while 13 genera are added not yet before met with 

 in Canada, two of which have never been described. 



I shall leave out the Urocerid(Z and Tenthredinidae, and not include 

 them in the following figures, as Mr. W. H. Harrington has given especial 

 attention to those two orders, and has already published an article on 

 them. 



As far as yet known, about no species new to Canada have been taken 

 in this neighborhood, and more than half of them have been pronounced 

 to be new to science by our high authority. Abbe' Provancher, who has 

 undertaken to describe them. 



As to those already described, the Abbe, who has been so kind as to 

 examine and identify them, has been greatly surprised at our possessing 

 here many insects never before found in so high a latitude. 



Order L Among the Apidce we have, for instance, obtained the red- 

 girded Bombus riifocinctus Cress. We have also, however, B. groen- 

 landicus Smith, which connects us with quite a different climate.
