12 ENTOMOLOGICAL NEWS. [January, 



The shape of the superior appendages in the males from Hermit Lake 

 varies but sHghtly (Figs. 6 and 7), while the maximum variation is shown 

 by those from Lake St. Regis (Figs, i, 3, 5). Those from Fabyan's, 

 Pictou, Sherborn and the Catskills incline towards the typical clepsydra 

 in this detail, the one from Nevvfoundland to the typical eremita. 



The number of denticulations on the carina of the superior appendages 

 varies from 4-9 (Hermit Lake), 4-8 (Fabyan's), 4-7 (Lake St. Regis), 

 5-7 (Catskills), 8 (Newfoundland), and is not always the same on the right 

 and left appendages of the same individuals. In the two males from 

 Sherborn the denticulations are so slight as to suggest that transitional 

 forms may hereafter be found connecting this species with ^. verticalis 

 Hag., which itself is but a variety of the circumpolar juncea L. (See 

 Trans. Am. Ent. Soc. xx, p. 248.) 



The following measurements show the variations in size in millimeters:
