54 THE CANADIAN ENTOMOLOGIST. 



Of 8 £ , 6 have 6 ocelli, i has 5, 1 has 5 on one wing and 6 on the 

 other. 



Every one of both sexes has a small ocellus at inner angle of hind 

 wing, on upper side. 



The uniformity of these characters- — the ocellus at inner angle always 

 present, and the number of small ocelli, which are scarcely ever less than 

 6 and never below 5 — in so many examples brought together from various 

 quarters contrasts strikingly with the great variability of Alope and JVephele 

 in the same points. 



Besides these eastern forms are others allied to them from the far 

 west. On the eastern side of the Rocky Mountains the Illinois type 

 seems to prevail. I have received it from Montana, Colorado and New 

 Mexico. On the Pacific side we have Boopis Behr, 1864, Ariane Bois., 

 1852, Paulus Edw., 1879, Gabbii Edw., 1870, and Wheeleri Edw., 1873. 



Boons. — Dr. Behr, Proc. Cal. Acad. Sci., 1864, distinguished Boopis 

 from Nephele by the absence of ocelii on under side of hind wings. The 

 male is dark brown and the ocelli on fore wings have nearly always a yel- 

 lowish ring, often faint. In the female this ring is enlarged and sometimes 

 the field is yellow tinted. I have one example in which it is nearly clear 

 yellow, and makes a broad clouded band. So far it approaches Alope. 

 Of 5 $ , 4 have 2 obsolescent ocelli beneath hind wings, 1 has 1. Of 7 

 °. , 1 has 3, 5 have 2, 1 has 1. Undoubtedly some Nephele females are 

 closely like Boopis % , if not undistinguishable from it, but the difference 

 between the ' males is more marked, one showing a full complement of 

 small ocelli in most cases, and less than four very rarely, the other never 

 reaching four so far as I am aware. Boopis flies from Arizona to British 

 Columbia. 



Paulus.— This species stands midway between the two groups into 

 which the American species of this genus may be divided, the lesser group 

 comprising Phocus, Silvestris (Oetus Bois.), Meadii and Charon. I 

 described Paulus from 2^,1°. taken by Mr. Morrison in Nevada, 1878, 

 but have since received a £ from Mr. Graef, taken in Utah, and a $ 

 taken at Soda Springs by Mr. Behrens, and 1 £ , 1 ? from Olympia. from 

 Mr. Morrison. I have also recently received a fine series of perfect 

 examples of Silvestris, taken by Mr. Baron in Northern Cal., and some of
