218 THE CANADIAK ENTOMOLOGIST. 



found any evidences of the destructive habits described by Mr. Fletcher. 

 It was, however, known to attack clover in Europe. 



He mentioned several insects found by him on Larch, such as 

 Urocerus flavicornis and Bupresiis maculiventris. During the previous 

 summer he had, in company with Mr. Fletcher, noticed a grove of tam- 

 arac with trees in various stages of health and decay, and the cause of the 

 latter seemed undoubtedly to be a species of De?idroctonus, which was 

 found in immense numbers under the bark of sickly and dying trees. The 

 bark was completely undermined and riddled by its galleries, and swarmed 

 with larvae pupae and beetles. Associated with them were large numbers 

 of a smaller bark-borer, Hylesinus opaculus, with one or two other species, 

 which would not be likely, from their habits or numbers, to do much in- 

 jury. Examination of dead trees showed that the bark had been de- 

 stroyed in the same manner, but now contained no beetles. 



In reply to a question as to whether such bark beetles ever attacked 

 living and healthy trees, Mr. Harrington answered in the affirmative, and 

 instanced a species which he had during the spring found boring into and 

 through the terminal buds of Finns strobus (white pine) and thus destroy- 

 ing them. 



EXHIBITION OF INSECTS. 



Mr. Harrington exhibited a small collection of about 50 species of 

 Coleoptera taken by him at Sydney, Cape Breton, during a visit of a few 

 days in September, also specimens of the Chinch bug which he had 

 found abundant there ; he also exhibited a Chalcophora liberta, with de- 

 formed thorax, a Trogosita mauritanica, with deformed head, and a wasp 

 (Vespa ?) with one of its antennae curiously deformed. 



Rev. T. W. Fyles showed specimens of Colias eurytheme, Pieris 

 Manitoba,, P. centaurece, a female of Smerinthus cerysii, and other rare 

 insects. 



Mr. J. Alston Moffat showed a collection of rare and interesting 

 insects, both Lepidoptera and Coleoptera. 



Mr. Fletcher exhibited a collection of 40 specimens of Colias 

 philodice, showing many curious varieties. Two specimens of Colias 

 eurytheme, one of which was the autumn form bred from the egg. Two 

 specimens of a small moth bred from larvae found boring in the flowers 

 and capsules of Nehimbium hiteiun at Chicago. A specimen of Sphinx 

 luscitiosa. A Hepialus taken at Dalhousie, N. B., very similar to H.
