66 The Ottawa Naturalist. [July 



* 



Mr. Baldwin exhibited his collection of lepidoptera and 

 pointed out some of the rarer species which he had taken at 

 Ottawa during the last year or two. Some of these were par- 

 ticularly interesting and the only records for the district.

The 7th meeting of the Entomological Branch was held at 

 the house of Mr. Halkett, on the evening of the 4th April, 1907. 

 There were present, Dr. Fletcher, and Messrs. Harrington, 

 Gibson, Young, Baldwin, Metcalfe, Wilson, and Halkett. 



Mr. Harrington exhibited two cases of hymenoptera, con- 

 sisting of the Siricoidea and a portion of the Tenthredinoidea. 

 The collection contained many interesting species from all parts 

 of Canada, and also some from the United States. Some of the 

 species were stated to be apparently undescribed, and types of 

 several species described by Provancher were included. Atten- 

 tion was directed to some of the more injurious forms, and to 

 the fact that the insects in this division of the hymenoptera 

 were of special interest, as the larvae were phytophagic, and often 

 so abundant as to cause great devastation. Mr. Harrington 

 also presented a list of forty species of spiders which had been 

 recently determined by Mr. Nathan Banks, and stated that 

 about a dozen were additions to the Ottawa list of Arachnida. 



Mr. Wilson made mention of the destruction caused in 

 Northern Ontario by the larvse of the Larch Sawfly, Nematus 

 Erichsonii, chiefly eastward of Nipigon, and referred to pet- 

 rified wings of sawfiies found by him in slabs of slate in New 

 Brunswick. 



Mr. Gibson exhibited a magnificent pair of the Imperial 

 Moth, Eacles imperialis, Dru., male and female, which had been 

 presented to the Division of Entomology by Mr. T. W. Ramm, 

 of Ross Mount, Ont. The species, although rare in Canada, has 

 been taken at Ottawa (once), Port Hope, Toronto, and one or 

 two other localities in Ontario. Specimens of Lepisesia ulalume, 

 Strck., from Vancouver, B.C. (A. H. Bush), and co-ty]3es of 

 Recttrvaria gibsonella and Recurvaria conijerella were also shown. 

 These two latter are new local species reared by the exhibitor, 

 and described by Mr. W. D. Kearfott, of Montclair, N.J. 



Mr. Young showed a box of microlepidoptera, which had 

 just been named for him by Mr. Kearfott. Among these were 

 10 new Ottawa species, the descriptions of which have just 

 appeared. The names Enarmonia youngana, Enarnionia flet- 

 cherana and Carposina ottaivana were of particular interest to 

 those present. Regarding the collection of these small moths, 

 Mr. Gibson spoke of a trap which had been devised by Mr. J. D.
