Hepialidee 



The range of this species is the same as that of the preceding. 

 It occurs rather abundantly in Assiniboia and Alberta. 



Genus HEPIALUS Fabricius 

 (i) Hepialus hyperboreus Moeschler, Plate XLI, Fig. 15, 6 . 



Syn. /«/^/'«^'' Grote ; macgiashani Henry Edwards. 



The moth is found in New England and southern Canada. 



(2) Hepialus gracilis Grote. (The Graceful Ghost-moth.) 

 This species, the neuration of the wings of which is repre- 

 sented in the text at Fig. 12, is not an uncommon species in the 

 northern portions of our territory. 



(3) Hepialus lemberti Dyar, Plate XLI, Fig. 16, 6. (Lem- 

 bert's Ghost-moth.) 



The moth is found in California. It is not as yet common in 

 collections. 



^ FAMILY MICROPTERYGID/E 



This family is represented in our fauna by two genera of 

 minute insects and six species. They are remarkable because 

 revealing certain anatomical features which are believed to point 

 to an ancestral connection between them and other orders of 

 insects. One of the remarkable features which they reveal is the 

 persistence in them of mandibles in the pupae, which are lost in 

 the imaginal form in the genus Micropteryx, which is not repre- 

 sented in our fauna, but are persistent in the genus Eriocephala, 

 which does occur in North America. 



We have arrived at last at the end of our necessarily com- 

 pacted but rather extensive survey of the families of moths rep- 

 resented in the fauna of the United States and Canada. We have 

 thrown the doors of our subject open to the curious. We have 

 thrown them wide open. Much has been omitted which might 

 have been said; possibly some things have been said which will 

 have little interest for the general reader; but, upon the whole, 

 we feel, in bringing this book to its end, that we have given a 

 fuller and more complete review of the whole subject to Ameri- 

 can students than has ever been essayed in any book by any
