234 THE CANADIAN ENTOMOLOGIST 



The less robust form which Scudder described as er em ita appears 

 in collections. The types of eremita are 3cf's and 9, Hermit 

 Lake, New Hampshire, now in the collection of the Boston Society 

 of Natural History. A cf and 9 eremita are in Dr. Calvert's 

 collection from the type locality. The writer has a male of this 

 form collected by Dr. Walker at Banff. Alhicincta and eremita

undoubtedly intergrade. Figs. 25-27 show specimens from Hermit 

 Lake, fig. 25 being from the type. The male from Banff resembles 

 fig. 26. See also figs. 13-16.- The types themselves are nearer 

 to the typical albicincta than the Banff or Dr. Calvert's speci-

Somatochlora septentrionalis (Hagen). 



This is the smallest species in the genus, the abdomen being 

 but 31 mm. in length. 



A male of this from Hudson's Bay was found in the Carnegie 

 Museum. It was so different from the specimen figured by William- 

 son (Ent. News, XVII, p. 138, as htidsonica) that it was considered 

 new until the two male types in the Museum of Comparative 

 Zoology were examined, when it was found that these type males 

 were intermediate between the Williamson male and this Carnegie 

 Museum male.
