Body generally rather robust, hairy ; wings large, considerably variegated, with the costal and median veins of the 



fore wings swollen at the base, and the apical margin somewhat scalloped. 

 Head rather small, thickly clothed with rather short hairs. 



Eyes prominent, naked. 



Labial Palpi rather short, porrected obliquely, but not reaching much above the level of the middle of the eyes, and 

 extending forwards about half the length of the head, rather thickly clothed beneath with moderately short 

 hairs ; the middle joint with a compressed conical tuft of hairs in the middle of the hinder margin ; terminal 

 joint very short and oval. 



Antennw not near half the length of the fore wings, very slender, articulations indistinct, not annulated with 

 white ; terminated either by a short, abrupt, broad, concave club, or by a long, slender, fusiform club, with its 

 base gradually formed. 

 Thorax oval, clothed especially behind with long soft hairs ; wings large. 



Fore Wings with the costal and median veins greatly swollen at the base. Costal margin well arched, apical angle 

 rounded, apical margin more tlian two thirds the length of the costal. Inner margin not, or scarcely, so long 

 as the apical one, nearly straight. Veins arranged as in Lasiommata ; the third and fourth branches of the post- 

 costal vein being, however, more approximate to each other, leaving a greater space between the extremity of the 

 discoidal cell and the third, and between the fourth and the tip of the wing. The upper disco-cellular vein is 

 extremely short and transverse, and the middle and lower ones nearly continuous and oblique; tlie latter 

 united witli the third branch of the median vein at about the same distance from its origin as exists between 

 the first and second branches. The discoidal cell extends to the middle of the wing. 



Hind Wings broadly ovate, more or less scalloped along the outer margin. The anal margin either entire, or 

 slightly incised near its extremity. A^eins arranged as in Lasiommata, except that the upper disco-cellular 

 vein is longer, and the lower disco-cellular is united to the third branch of the median vein at a rather shorter 

 distance fi'om its origin than exists between the first and second branches of the median vein. 



Fore Legs of comparatively moderate length, and distinctly visible in both sexes ; those of the males being much 

 more densely clotlied with liair, and those of the female rather larger. Tarsus simple in the males, but 

 articulated in the females ; not armed, however, with minute spines at the tips of the joints. 



Four Hind Legs rather short, scaly. Femora almost entirely destitute of hairs beneath. Tibjaj armed with 

 several rows of spines, set rather widely apart, at the sides beneath ; tibial spurs very acute, and rather long. 

 Tarsi armed beneath and at the sides with several rows of short spines ; tips of the joints with longer spines. 

 Ungues entire, long, very acute, and curved. Paronychia very slender. 

 Abdomen moderately elongate-ovate. 



Caterpillar pubescent, elongate-conical ; head rounded ; tail bifurcate ; body marked with dark 



longitudinal stripes. 

 Chrysalis shoi't, ovoid, glabrous, with the head obtuse and tail pointed; either suspended by the tail, or 



enclosed in a cocoon of earth mixed with a little silk. 



It is here proposctl to limit the genus Satyrus to those species, generally of large size, which arc distinguished by having the costal 

 and median veins of the fore wings dilated at the base, the submedian vein being simple, and by having the eyes naked. The characters 

 detailed above are chiefly derived from S. Scmele and Fidia ; but numerous modifications, of sliglit value, however, occur in most of 

 the characters of the different species. Thus, the club of the antennaj varies in shape from the insensibly formed and very slender 

 condition in S. Tithonus, &c., to the short, broad, nearly rounded form in S. Scmele. The palpi, also, differ somewhat in length, as well 

 as in their clothing of hairs. There is also some diflcrcnce in the situation of the second branch of the postcostal vein of the fore 

 wings, which in 8. Ilyperanthus * arises opposite the origin of the upper disco-cellular vein, at the extremity of the discoidal cell. 



* Tliis species differs not only in tlie place of insertion of tlio second branch of the postcostal vein, but also in the elongated yery hairy palpi, and in the 

 style of its markings. It has consequently been separated by Mr. E. Doubleday, with S. Alope, under llie generic name of Enodia.
