872 AMERICAN LEPIDOPTERA. 



is pale, except for an olivaceous clouding at middle. There is a series of dusky 

 terminal lunules from wliich short interspaceal lines extend inwardly. The 

 reniform is only a little dusky, moderate in size, lunate, not well defined. Sec- 

 ondaries dull yellowish, darker outwardly, with a dusky extra median shade; 

 the outer margin and the abdomen with a coppery tinge. Beneath yellowish, 

 outwardly and costally with coppery-red powdering; primaries with a dusky 

 extra-median and s. t. shade line and discal s})ot ; secondaries with similar but 

 much less marked and incomplete brown lines. Expands 1 inch = 25 mm. 



Hab. — Esper Ranch, Brownsvills, Texas. 



One male in good condition from the collection of the Brooklyn 

 Institute, taken by Mr. Schaeffer. 



The lateral ciliation of the antennte is much more obvious than 

 in any other of the species, a single long cilia on each side of each 

 joint appearing clearly under the lens, and this character will assist 

 in distinguishing it from all the others. In the olivaceous and 

 greenish-gray color and ornamentation it is also unique thus far. 

 The secondary sexual tuftings of the underside appear to be in all 

 respects like those of incusalis, and that applies to the tuftings at 

 the base of the abdomen as well as to those on the wings.

 Ground color varying from pale gray to pale yellowish, more or less creamy in 

 effect. Sides of palpi scarcely darker. Primaries with the median lines usually 

 black, conspicuous, the t. a. outwardly, the t. p. inwardly diffuse, tending to fill 

 the median space more or less solidly brown or blackish. T. a. line outwardly 

 oblique with a little bend or angle in the submediau interspjice, sometimes pre- 

 ceded by a narrow pale or even whitish shade line. T. p. line almost evenly 

 oblique from costa to vein 4, then with a distinct incurve that gives the line a 

 characteristic form ; usually there is a narrow whitish or yellow outer edging to 

 this line which merges into the s. t. space. S. t. line altogether wanting or, more 

 usually, defined by a smoky s. t. shading that may be broken or continuous. 

 There raa.v be obvious terminal lunules, but more usually there is no trace of 

 them. Eeniform lost or only present as a dusky indication. Secondaries yel- 

 lowish, a little darker and more brownish outwardly ; sometimes with an extra 

 median line. Beneath, pale lemon-yellow, primaries with a small discal spot 

 and iui incomplete extramedian line. Expands .95-1.05 inches = 24-26 mm.

A series of seventeen examples, male and female shows a pretty 

 range of variation in color and in the relative contrast of the median 

 lines and space. In the course of the lines there is almost no varia-
