 is a little variation in ground color and the. amount ot sliadin.n' to the 

 transverse lines, and this is really all that separates the nominal species 

 described bj' Mr. (Irote. 



The species does not seem to be common anywhere within its ran/ie, 

 aud it is found in very few collections only.

Ground color pearl gray, with black, rather sparse powderin f^s. Head 

 and thorax concolorous; abdomen more luteous or smoky. Primaries 

 with three even inwardly oblique fascia, consisting of a brown aud a 

 yellow line or shade, the. latter following the basal line, but preceding 

 the others. The inner line is either abbreviated on the costal vein or 

 it reaches the costa, bending inwardly on the vein. The middle fascia 

 crosses at just about the center of the wing, while the outer is incurved 

 from the apex to the margin close to the hind angle. The ordinary 

 spots are obsolete. Secondaries smoky or yellowish, a little darker 

 outwardly, with a trace of a pale subterminal line toward the iuuer 

 margin. 



Expanse of wings, -58 mm. = 1.12 inches. 



Habitat. — Texas. 



The species is easily recognized, differing by its larger size and 

 absence of all trace of the ordinary sjwts from the more common form. 

 The bibliography above given is, of course, extremely incomplete, and 

 Walker and Staudiuger should be referred to. There has been no ref- 

 erence to the species in American i)ublications so far as I am aware, 

 aud, as I have already indicated, the American habitat of the species 

 is not at all beyond doubt.

Lederer describes this genus as follows: More robust tluin the pre- 

 vious genus {Pechipogon) ; the abdomen shorter, the primaries more 

 pointed, nearer to the following JIi/poKC. Front with a pointed tuft. 

 Palpi horizontal, exceeding the hea<l by more than its own length;
