Head, thorax and primaries ash gray, dorsal crest of thorax usually more or 

 less discolored, as is also the vertex ; patagise usually margined with fuscous 

 brown, and in .some specimens a fuscous tint invades the ground color. Abdomen 

 with a broad dorsal gray line ; on each side of this the segments are banded with 

 black and gray. Beneath paler, whitish gray. Primaries in some specimens 

 almost immaculate, an outer interrupted, dentate, transverse line and a row of 

 terminal dots only traceable; more usually, however, there is a longitudinal fus- 

 cous and l)lackish shade from middle of base through the centre of the wing to 

 the apex ; above this there is always a fuscous tinge, and sometimes it becomes 

 well marked ; below this the fuscous suffusion is more rarely marked. The 

 maculation is fragmentary, augulated and diflScult to describe ; a variably dis- 

 tinct ba.sal line reaching from costa to the longitudinal line; a geminate line 

 nearer the centre of tiie wing; a geminate, strongly dented outer line parallel to 

 the outer margin, often reduced to a double series of venular dots ; a row of 

 inter-spaceal terminal dots. Discal dot black, at the extreme upper angle of the 

 cell. Secondaries dull red, with a broad black outer margin, not reaching the 

 anal angle, where there is a bluish gray patch. Beneath dull red basally, out- 

 wardly dusky fuscous, a dentate outer common line. Expands 3 — 3.50 inches ; 

 75—88 mm. 



Hab. — Fhjrida and .southward; westward to California; noi'th 

 ward occasional to northern New York and Massachusetts.
