LEPTOCIRCIN^E. 307 



GENUS BARONIA. 



Baronia, Salvin, Trans. Ent. Soc. London. 1893, p. 331. 



Under the name of Baronia brevicornis, Mr. Salvin has 

 described a new form of Butterfly from Western Mexico (Sierra 

 Madre del Sur, near Chilpancingo, at an altitude of about 4,500 

 feet), which is remarkable for its very short antennae, with a 

 long club, and the long hair-like frontal scales, which are drawn 

 down between the eyes. The sub-costal nervure of the fore-wings 

 is three-branched, " the first branch arising at a distance from 

 the end of the cell about equal to its width, and the second 

 the same distance beyond; the usual third branch from the 

 end of the cell is wanting, as well as either the first or second 

 before the end of the cell ; the upper disco-cellular nervule is 

 short, and the middle disco-cellular about twice as long as the 

 lower." The wings are brown, the fore-wings with rows of 

 ochreous spots, those towards the tip whitish in the female, 

 and the hind-wings with the upper part of the cell and the 

 space above nearly to the costa yellowish-ochreous, and with 

 several additional spots of the same colour. 



SUB-FAMILY IV. LEPTOCIRCIN^E. 



I have ventured to separate the anomalous genus, Lepto- 

 circus, Swainson, as a distinct Sub-family. The head and body 

 are very thick, the abdomen short, the eyes large and pro- 

 minent, the palpi very short and thick, with long stiff hairs in 

 front, and the antennae thickening into a club, which is slightly 

 curved upwards. In one species only, L. curius (Fabricius), 

 the claws of the tarsi are bifid, as in the Pierida ; in the others 

 they are simple. The fore-wings are short, sub-triangular, with 

 the tip rather pointed, and the hind-margin oblique ; the outer 

 part is hyaline, except at the edges. The hind-wings are long, 

 folded, and produced into a very long tail. On the fore-wings
