Genus Thymelicus 



Chrysalis, I can discover no account of any observations 

 made upon the chrysalids of this genus. 



(1) Thymelicus brettus, Boisduval and Leconte, Plate 

 XLVII, Fig. 40, 3 ; Fig. 41, ? (The Whirlabout). 



Butterfly. The male on the upper side resembles Hyleplnla 

 phvlcens, but may be distinguished by the broader and darker 

 spots on the under side of the wings. The costal 

 and outer margins of the secondaries are also gen- 

 erally more broadly bordered with fuscous than in 

 pbyltfits, a fact not shown in the specimen figured 

 in the plate. The female is quite different from the 

 female of phylceus, as will be seen by a comparison 

 of the figures of the two sexes. Expanse, $ , 1.15 

 inch; ? , 1.25 inch. 



Early Stages. These are only partially known. F[G i6

The insect is very rare in the North, a few speci- 

 mens having been taken in New England and Wis- 

 consin. It is found commonly in the Carolinas, and thence south- 

 ward to the Gulf, and is abundant in the Antilles, Mexico, and 

 Central America. 



(2) Thymelicus setna, Boisduval, Plate XLVI, Fig. 28, $ ; 

 Fig. 29, ? ; Plate VI, Fig. 42, chrysalis (The Volcanic Skipper). 



Butterfly. Both sexes are well represented on the upper side 

 in the plate. On the under side the wings are paler, with the 

 light spots of the upper side repeated. Expanse, $ , i.oo inch; 

 ? , 1.25 inch. 



Early Stages. What we know of these is well stated in the 

 pages of Dr. Scudder's great work. The caterpillar usually feeds 

 on grasses. 



The species ranges from New England, Ontario, and Wis- 

 consin on the north to the Gulf, and as far west as Iowa and 

 Texas. 



(3) Thymelicus mystic, Scudder, Plate XLVI, Fig. 22, $ ; 

 Fig. 23, ? (The Long-dash). 



Butterfly. No description of the upper side is needed, the 

 figures in the plate being sufficient to enable identification. On 

 the under side the primaries are fulvous on the costa at the base. 

 The remainder of the primaries and the secondaries are dark fer- 

 ruginous, with the light spots of the upper side all repeated
