LEriDOPTERA. 
in the male, is a short, curved, deep black line ; hind wings 
with an indented tawny band, or row of unequal spots, 
behind the middle, which, m the male, are very indistinct; 
beneath, light brown ; fore wings 
marked with bright yellow spots ; 
liind wings with a very large, irreg¬ 
ular, bright yellow spot, covering 
nearly the whole under surface, and 
almost divided in two near the middle. 
Expands from lyV to ly-y 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. Cemes ? 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 ly^^ 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.
