THE CANADIAN ENTOMOLOGIST. 385 



concerning the precise identity of H. similis and H. discus of Smith, the 

 descriptions of which proved inadequate. I have just taken occasion to 

 re-examine the types at the British Museum, and after very careful 

 comparisons I conclude that H. similis is identical with the European H. 

 hucozonius. With the type in my hand, I fail to appreciate the differences 

 mentioned by Smith, or to discover any means of separating the two. 



The following table separates the females of H. similis and H. discus 

 from species which they closely resemble : 



Area of metathorax large, with irregular raised wrinkles ; mesothorax 

 densely punctured (Japan) proximatus, Sm. 



Area of metathorax strongly longitudinally ridged i. 



i. Larger; mesothorax very shiny, with strong sparse punctures; scutellum 

 with large punctures, but a large area on each side of middle 

 impunctate ; basal hair-bands conspicuous ; hind spur with about 



four short triangular teeth discus, Sm. 



Smaller ; mesothorax densely punctured 2. 



2. " Disc of basal segment of abdomen shining and remotely 



punctured " (E. Saunders) zonulus, Sm. 



Disc of basal segment of abdomen finely and closely punctured all 

 over leucozonius, Schr. (similis, Sm.). 



In the male, according to Mr. E. Saunders, the tarsi are entirely 

 black in H. zonulus, while they have the basal joints pale in H. 

 hucozonius. 



ENTOMOLOGICAL SOCIETY OF ONTARIO. 



The Entomological Society has held its regular fortnightly meetings 

 during the College year. The first meeting of the fall term was held on 

 October 21st, and the last meeting of the spring term on March 17th. 



At all the meetings the student body was well represented, especially 

 by the members of the senior years, many of whom gave most interesting 

 and valuable papers on subjects pertaining to the investigational work 

 they were carrying on for their Fourth-year Thesis, or to the work in 

 Entomology at which they were employed during the summer vacation. 

 The preparation of these papers was entered into with enthusiasm by the 

 students, who were glad to avail themselves of the opportunity of placing 

 the results of their labours before an appreciative audience. The practice 

 obtained in preparing such papers and delivering them in an acceptable 

 manner, is invaluable to the student of Entomology who desires to fit
