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



Allied to Papilio, and with the arrangement of the median nervure and its branches 

 with relation to the lower discocellular of the primaries similar ; the subcostal, however, 

 has only two branches instead of four, the first 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 discocellular is short and the middle discocellular 

 about twice as long as the lower. Antenna? very short, less than the first median 

 segment of the primaries, with a comparatively long thick club. Palpi very short, 

 hardly perceptible amongst the long hairs on either side of the haustellum. Frontal 

 scales long and hair-like, but drawn downwards between the eyes and not erect as in 

 Papilio. Legs with short spiny joints ; a distinct epiphysis on the anterior tarsi.

Alis fuscis, anticis maculis in seriebus tribus arcuatis ochraceis ; posticis litura fere totam cellulam occupante 

 et costam versus extendente, maculis tribus infra venam medianam triangulum formante, aliisque sex 

 parvis in serie submarginali, omnibus ochraceis: subtus pallidioribus, anticis maculis ut supra, una 

 quoque apicali, aliisque parvis marginalibus, iis tantum apicem versus argenteis ; posticis maculis 

 omnibus argenteis, iis in serie submarginali elongatis et ad apicem extendentibus, una parva ultra 

 cellulam et linea iiiterrupta marginal! angulum analem versus notatis ; ciliis inter venas albidis. 



2 mari similis, sed major et maculis ochraceis majoribus, aliis margines externos versus coloris ejusdem et in 

 posticis plus minusve confluentibus. 



Eab. Mexico, Sierra Madre del Sur, near Chilpancingo, 4500 feet (Baron l ). 



We are indebted to Mr. Baron for a pair of this interesting species, which, with a 

 few others, were captured by himself in Western Mexico, in the months of June and 

 July, a few years ago. The shortness of the antennae and the peculiar neuration of the 

 wings at once show that it cannot be referred to any known genus of Papilionidae.
