316 LEPIDOPTERA. 



in the male, is a short, curved, deep black line ; hind wings

° ' marked with bright yellow spots ; 



Usfe^n&i^^ Br nm ol wings with a very large, irreg- 



IBpgjr ular, bright yellow spot, covering 



^HB^^^P^ nearly the whole under surface, and 



almost divided in two near the middle. 



Expands from 1 T V to l T 2 o inch. 



This skipper was named by Mr. Kirby in honor of the 

 late Professor Peck of Cambridge, and is figured and de- 

 scribed in the fourth volume of the " Fauna Boreali Ameri- 

 cana." The upper surface of the female resembles that 

 of the same sex of the Phylceus of Drury or Vitellius of 

 Fabricius ; but the under side is different. It is found on 

 flowers in meadows in the latter part of July and in August. 



Hesperia Cernes ? Boisduval. Cernes ? Skipper. 



Dark brown above, fore wings of the male with a large 

 brassy-yellow spot, extending from the front edge beyond the 

 middle, and an oblique wavy black line ; hind wings with a 

 brassy gloss ; under side of the fore wings tawny yellow 

 before, dusky behind, with a pale yellow oblique spot near 

 the middle, and two or three minute spots of the same color 

 near the front margin ; hind wings dusky ochre-yellow be- 

 neath, with a transverse row of four small paler yellow 

 almost obsolete spots ; head and body glossed with green 

 above, yellowish white beneath. 



Expands 1 T \ inch. 



In one individual from the Southern States there are two 

 or three minute yellow dots on the fore wings between the 

 oblique line and the tip. I think it probable that this may 

 be the species figured, but not described, by Dr. Boisduval, 

 under the above name. It is found in the latter part of 

 July, but seems to be rare, and the female is unknown to 

 me.
