Genus Hesperia, t\ihy. (Syrichthus, Bsdv.). 



Uhs. This is by far the most ditJicult Renus among the butterflies, the same 

 names havin«>- been in some cases applied to different forms, and each fresh 

 attempt at elucidation having,' often made matters more confused than before. 

 This applies specially to the various forms of Alveus and Serratuhe. Moreover, 

 the sp. resemble one" another in a gen. way so closely, and yet the individuals 

 vary so greatly in a single sp.. that the difficulty is increased tenfold. In 

 addition to all this, no two collections seem to agree in their separation of the 

 sp. and vars., and I am. as yet, far from feeling the comparative certainty in 

 this genus that I feel, ri<;htly or wrongly, in Krebia and Milita?a. Tuder these 

 circumstances experience will no doubt discover errors in the following treat- 

 ment of this genus, and, in particular, it may be said that the localities for the 

 more obscure and uncertain forms are by no means implicitly to be relied on, 

 as it is sometimes far fi'om certain to what exact forms they refer. ]
