tinge — usually tlie former. Head with superimposed tufts distinct, and with a 

 hrown frontal line, below which it is reddish. I'ollar unlined, thoracic crest 

 hardly marked, vestiture flattened hair and scales, patagise tipped and laterally 

 marijined with chocolate brown. Primaries with curved black streak at base, 

 diffuse inferiorly, strongly contrasting. All the lines geminate, little darker 

 than the ground, tending to become lost, always marked on the costa. T. a. line 

 nearly upright, a little outcurved in the interspaces. T. p. line with inner por- 

 tion slender, even, not lunulate or crenulate, a little dentate or angulate on some 

 of the veins, occasionally lost, outer portion diffuse, usually lost below the out- 

 curve over cell. S. t. line marked onlj^ by a pair of black contrasting spots in 

 the submedian interspace and opposite the cell. A series of distinct, black, ter- 

 minal lunules in the interspaces. The median shade extends as a contrasting 

 brown or black shade from the costa between the ordinary spots, is then lost or 

 traceable as a slightly darker shade only, until it gets below the internal vein, 

 where it forms a black or brown patch on the inner margin. Claviform barely 

 indicated in one example. Orbicular large, concolorous, opeii to the costa, sides 

 more or less obviously marked by black scales. Eeniform large, almost as broad 

 as long, incompletely black ringed, more or less brown and black filled. Second- 

 aries smoky, with a purplish tinge. Beneatli powdery, with a carmine shading, 

 a more or less obvious outer dark line, and on all wings a blackish discal spot. 

 Expands 38-42 mm. = 1.56-1.68 inches.

One pair only is at present before me, hut I have recently com- 

 |)are(l several others which do not greatly ditler. The species is dis- 

 tinct in many ways and can always be recognized by the contrast- 

 ing, square, dark brown or black patch between the ordinary spots 

 and partly including the reniform. Other ornamental features have 

 l)een elsewhere noted. The thorax seems to be unusually short, 

 almost square, depressed and with collar and patagipe much less 

 marked than usual. The male antennae are very shortly ciliated, 

 the joints scarcely more marked than in the female.

Head, thorax and primaries a dull, pale, greenish gray. Head white below 

 the usual tuftings. (\)llar with an obscure blackish line below tip. Thoracic 

 vestiture scales and flattened iiair, the crest indicated by a little tuft of discolored 

 scales. Primaries with all the markings blackish, fairly evident, but not in the 

 least contrasting. Basal streak traceable. Basal line geminate, marked on the 

 costa only. T. a. line geminate, inner portion lost or very feebly marked, out- 

 wardly oblique, a little outcurved in the interspaces. T. p. Hue geminate, broken, 

 outcurved over the cell and then almost upright to inner margin. S. t. line 

 marked by a series of partly contiguous blackish spots, indicating an irregularly 

 bisinuate course. A series of interspaceal terminal lunules. Median shade 

 difluse, almost evenly oblique from costa to inner margin between the ordinary
