170 THE CANADIAN ENTOMOLOGIST. 



Montanus Brem. is distinguished from the others above, which accord 

 with it pretty well in habitus, by the particularly large hind-wings with 

 expanded margin, also by the difference of color and marking ; but it has 

 all the essential characters of the genus. Its club is somewhat thicker 

 than in Tages, but is otherwise of the same shape. 



Thanaos. 



Club of antennae elongated, curved, shorter than in Nisoniades, sud- 

 denly swollen, and scarcely contracted at the well rounded tip. Fore- 

 wings more elongate than triangular, the front margin more steeply arched 

 above the base, the hind margin shorter. Male destitute of the costal 

 fold. All the other characters as in Nisoniades. 



The erection of a separate genus for Marloyi is more difficult to justify 

 than even the somewhat artificial separation of the genus Scelothrix from 

 Pyrgus. For the absence of a costal fold, their principal character, as has 

 already been shown in Pyrgus, is insufficient to establish a generic value ; 

 the antennal club differs only in its shortness and stoutness, and no 

 importance can be attached to the slight difference in the cut of the 

 wings. All three of these features taken together induce me to consider 

 it more proper, for strict systemization, to set apart this element which 

 disturbs the establishment of a generic character for Nisoniades. In order 

 to avoid constructing a new generic name, I have used that which Bois- 

 duval selected to include Tages and Marloyi.
