THE CAXADIA.X ENTOMOLOGIST. 179 



A letter was read regarding supposed injury to greenhouse plants 

 caused by a beetle, specimens of which were submitted. These were 

 seen to be NacerJes melanura^ a European insect introduced through 

 commerce. It is now very abundant in warehouses downtown, particu- 

 larly near the wharves, and is often seen in numbers on sidewalks 

 throughout the summer. 



Mr. Winn read a short paper entitled "A Miniature Insectary," 

 describing a space in his cellar boxed in around a south window, the 

 inner of the double windows having been moved about three feet back, 

 the outer window being left on during the winter and replaced by a wire 

 screen in summer. The space only amounted to perhaps 40 cubic feet, 

 but was sufficient to accommodate on shelves a number of breeding cages, 

 jelly jars, boxes and tubes, and the conditions seemed to suit the insects, 

 as there were practically no failures to get imagoes or parasites. 



Mr. Moore read a paper on "Sexual Differences in Hemiptera," 

 illustrated by specimens. Size and colour are the usual characters. 

 Females of most species were much more seldom found in collecting than 

 males, whether this was due to secretive habits of the females he did not 

 know. 



The Secretary followed with a paper on "The Determination of Sex 

 in Lepidoptera. Several boxes of specimens were shown to illustrate the 

 superficial points of distinction. The structure of the antennœ, the 

 frenulum and some slides of genitalia were shown under the microscope. 



Copies of Dr. Barnes' and Dr. McDunnough's "Contributions to 

 N. A. Lepidoptera," Parts I-III, were shown. 



Meeting March çth. — At the residence of Mr. Lachlan Gibb ; 10 

 members present. Mr. Chagnon, Vice-President, in the chair. 



The question of finding a new place for the cabinet and book cases 

 was taken up, owing to Mr. Gibb's departure for England, and Mr. 

 Lyman offered to look after it temporarily. 



A paper on "Rye's Newest Moth," by Henry Bird, Rye, N. Y., was 

 read by the Secretary. The paper (jealt with the discovery of Gortyna 

 erepta boring in the roots of a coarse grass on the shore of the Atlantic. 

 The species had previously been taken only in Kansas. 



The chairman then announced that he had a pleasing duty to per- 

 form, and handed to Mr. Lyman an illuminated address, signed by all the 

 members of the Branch, expressing their good wishes on the occasion of 

 his marriage. Mr. Lyman replied, thanking the members for their gift. 



Copies of two parts of the "Genera Insectorum," dealing with the 

 family Geomelridas, were shown by the Secretary, as well as some draw- 

 ings of structure of the Brephinae. — A. F. Winn, Secretary.
