130 The Ottawa Naturalist [Oct. 



sented by only a single specimen. The Chrysomelids, or "leaf- 

 beetles," are mostly short-bodied, and more or less oval in out- 

 line. They are all vegetable feeders and some are very injurious. 

 The well known Colorado Potato Beetle is one of the bad pests 

 belonging to this family. 



Mr. Baldwin showed samples of several kinds of blank 

 labels which he had received from the American Entomological 

 Co., of Brooklyn, N.Y. It was pointed out that these labels 

 were very cheap and useful, and as this firm advertises in the 

 Ottawa Naturalist the members were requested to bear it 

 in mind when making purchases of an entomological nature. 



Mr. Metcalfe exhibited a small box containing a number 

 of spiders' nests, from which parasites had been reared. The 

 common local nest, fiat in shape and oval in outline, of a satiny 

 brown colour, had been chiefly collected and from these some 

 parasites of the genus Pezomachus had been secured. The name 

 of the spider that made the nest was unknown to those present. 



Dr. Fletcher showed a very large specimen of the ichneu- 

 monid fly, Ophion macrurum, which had been reared from the 

 cocoon of Telea polyphemus. It was noticed that the Poly- 

 phemus cocoon had been punctured by a w^oodpecker, but the 

 cocoon of the Ophion inside had not been injured, doubtless 

 because of its toughness. The little moth shown at a previous 

 meeting by Mr. Harrington, the larvae of which fed on Lemna, 

 was reported by Dr. Fletcher to be Nymphula ohliteralis, the 

 identification having been made by Dr. H. G. Dyar, of the 

 U.S. National Museum. Dr. Fletcher also exhibited specimens, 

 in fluid, of the larva of the Mexican Orange Fruit-worm fly, 

 Trypeta ludens, which had been found at Ottawa in a bitter 

 orange, and brought to one of the botanical branch meetings 

 by Mr. G. H. Clark. When first noticed the larvae were dead 

 and discolored. A list of species of the genera Bombus and 

 Psithyrus from various parts of Canada, which had recently 

 been determined by Mr. H. J. Franklin, of Amherst, Mass., 

 was read by Dr. Fletcher and proved of much interest. Local 

 species included in the list were: Bombus borealis, B. impatiens , 

 B. pennsylvanicus , B. perplexus, B. vagans and Psithyrus labori- 

 osus. 



Mr. Young exhibited a large case containing about 900 

 specimens of local microlepidoptera, many of which had been 

 reared by him from larva. It is always a pleasure to look over 

 any of Mr. Young's work, and this exhibit was an extremely 

 interesting one. Many of the rarer or recently described species 

 were pointed out and information given as to the food plants 

 of the larvae.
