THE BRIZO SKIPPER. 309 



Tluniaos Juvenalis, Fab. Juvenal's Skipper. 



Smoky brown on both sides ; fore wings variegated above 

 with o-ray, with transverse rows of dnsky spots, and six or 

 seven small semi-transparent white spots near the tips ; six 

 of these spots are disposed in a transverse row, bnt the two 

 hindmost are separated from the others by a considerable 

 interval, and the seventh spot, which is sometimes wanting, 

 is placed nearer the middle of the wing ; hind wings with a 

 row of blackish spots near the hind margin.

There is a local variety of this skipper, that is much more 

 common in jNlassachusetts than the preceding, of inferior 

 size, seldom expanding more than IjV ii^cli, in Avhich the 

 white spots are smaller, and the seventh is Avanting near 

 the middle of the fore wing. This skipper is found in 

 meadows in May, and again in August. The caterpillar 

 lives on various pea-blossomed plants, such as the Glycine^ 

 or groundnut, the Lathyrus, or vetchling, &c. It is green, 

 with pale stripes, and a heart-shaped brown head. The 

 chrysalis is rather long and tapering, according to Mr. Ab- 

 bot of a green color, and is enclosed in a cocoon of leaves 

 and threads ; in my specimens pale yellowish brown, with 

 a few minute hairs on the body, and with the tongue-case 

 prominent and projecting beyond the middle of the breast ; 

 and the cocoon was composed of stubble. Mr. Abbot in- 

 forms us that in summer the skipper leaves the chrysalis in 

 nine davs ; but the autumnal brood continues in the chrysalis 

 state throughout the winter.
