separated from the median l)v scarcely (male) or considerably (female) 

 more than its width; area of the cubital forks broad and occupied by 

 more than one row of pol^'gonal cells. Wings with the disk yellow 

 or greenish yellow, and the fuscous band distinct but never in width 

 equaling one-third the length of the wing. Posterior femora having 

 the basal half of the disk of the inner face never entirely black (rarely 

 the whole inner face may be suffused with fuliginous, so that the usually 

 lighter areas are almost as dark as the black ones), but with a light 

 area of greater or less extent at the base, so that the usual appearance 

 is light, with three black bands, one on the knee, one at the middle, 

 and one between; the basal one, as it increases in size, assumes the 

 appearance of a stripe, which, however, never reaches the base. 

 Freiiuently the light area is suffused with red. Posterior tibiffi red, 

 rarely with a distinct subbasal annulus, but always with some trace of 

 a yellow or brownish cloud on the exterior face.

Color reddish or grayish brown, thickly and rather conspicuously 

 maculate, with fuscous cheeks and front of the head generally livid 

 and less maculate. Size medium, Scutellum moderately sulcate, a 

 very little longer (male) or shorter (female) than broad, with the median 

 carina very indistinct or wanting; median and lateral faveola3 only 

 moderately impressed; eyes small, distinctly (male), or considerably 

 (female) shorter than the genal groove. Pronotum with the median 

 carina slightly cristate on the prozone and bilobed; metazone rather 

 more than once and a half as long as wide, with the disk smooth, and 

 a few scattered larger granulations; process of the metazone strongly 

 obtuse-angular. Avith the sides straight and scarcely rounded. Teg- 

 mina short and broad, with the basal bands not solid, but showing some 

 evidence of l)eing composed of fuscous points; maculations on the 

 apical third al)out as thick and scarcely less distinct in the middle 

 than along the margins of this area; extreme base never entirely free 

 from fuscous points. Wings broad, about one and three-fourths times 

 as long as In'oad, with the tip very little attenuate and sinuate behind 

 the second lobe; disk greenish or citron yellow, with a moderately 

 broad and very distinct fuscous band, varying in width from a sixth to 

 a fourth the length of the wing, continued upon the posterior border 

 plainly less or decidedly more than halfway to the aiml angle, spur 

 extending a little more or less than halfway to the base; apex hyaline, 

 with rarely a few fuscous points. Posterior femora rather distinctly 

 banded on the outside; inner face yellow, more or less suff'used Avith 

 red, with three black bands, the basal largest; lower sulcus yellow 

 or red, with one indistinct subapical l)lack band. Posterior tibiae bright
