V. — Descriptions of twenty-jive neio Species q/" Hesperidae. 

 By W. C. Hewitson. 



When ten years ago I described 176 new species of Hespe- 

 rida'f I stated that I would apologize for doing so (knowing 

 the wortlilessness of descriptions unaccompanied by illustra- 

 tions) if I did not hope to figure the whole in the ' Exotic 

 Butterflies.' I am hap])y to say that nearly the whole have 

 been figured; and, though I cannot now make the same 

 promise, since that work has come to its hundredth and 

 final part, I still hope to figm*e the Hesperid(e which I am 

 now describing in the ' Illustrations of Diurnal Lepidoptera,' 

 in which the Lyccunidce now make their appearance. I may 

 repeat now what I stated then, that, although numbers of 

 Hesperidce differ little on the upperside, some characteristic 

 traits exist on the underside of the posterior wing ; and upon 

 these I have chiefly relied to enable me to discriminate on«» 

 from another. 



Hesperia Gonessa. 



Alls utrinque fuscis : anticis punctis oeto hyalinis : his infra angulo 

 anali albo fasciaque submarginali pallida: posticis infra fasciis 

 duabus macularum pallidarum : abdomine albo. 



Upperside dark brown. Anterior wing with eight small 

 transparent Avhite spots — two in the cell, three in a longitu- 

 dinal band below these, and three near the apex : the fringe 

 of the posterior Aving and the abdomen white. 



Underside as above, except that the anal angle of the ante- 

 rior wing is broadly white, and that there is a submarginal 

 series of indistinct pale spots, and that the posterior wing has 

 two submarginal series of similar spots. 



Exp, 1^ inch.
