cum eruca crescit, earn paulatim consumens," — implying continued obser- 

 vation, and also from the fact that Prof. Comstock found his larvse upon 

 half-grown cotton worms, the opposite view can be readily held. The 

 species, I think, may appropriately be dedicated to Prof. Comstock.

OTTAWA FIELD NATURALISTS' CLUB. 



TRANSACTIONS NO. I. 



The records of the first year's efforts of this active and enterprising 

 organization fill a goodly octavo pamphlet of sixty-two pages, which is 

 adorned with two excellent plates. From the annual report of the Council, 

 contained therein, we learn that the Club has a membership of over eighty, 

 and that five excursions, for the purpose of collecting objects of natural 

 history, have taken place during the year, with an average attendance of 

 thirty. During the winter months a successful series of soirees were held, 

 seven in number, at each of which interesting papers were read by mem 

 bers, and the specimens collected on the excursions exhibited. Many of 

 the papers are published in the transactions ; also a list of plants collected 

 in the Ottawa district by the energetic Vice-president, Mr. Jas. Fletcher. 



In the successful maintenance of this Natural History Club, Ottawa 

 has set a noble example, which we trust will be speedily followed by 

 similar organizations in other cities of our Province.

 be 4-jointed instead' of 5, and the parts of the mesothorax should be entirely revised.
