C'uereo fuscous. Head light bnvm or yellowish brown, the upper 

 half and sometimes the wliole head mottled rathe? heavily, on the 

 top of the head very heavily, with brownish fuscous, often becoming 

 blackish in a median band on the top of the head and less disiiuctly 

 above the upper eddies of the eyes; vertex gently tumid, slightly 

 elevated above the pronotum, the interspace between the eyes but little 

 broader than (male) or fully twice as broad as (female) the tirst an- 

 tennal joint: fastij^ium distinctly sulcate, most deeply in the male, with 

 distinct and nearly straight, raised, lateral margins, which pass into 

 tl»e lateral margins of the frontal costa; the latter distinctly punctate 

 next the margins like the whole of the face, nearly equal but slightly 

 narrower above, the surface plane except for a slight, short, narrow 

 sulfation at and below the ocellus; eyes of moderate size, not very 

 prominent, the front margin subtruncate, rather longer (male) or dis- 

 tinctly shorter (female) than the infraocular portion of the geuae: 

 antennae brownish yellow, becoming dusky toward the tips, in the 

 female a little more than three-fifths as long as the hind femora. Pro

 fullness, and on either side of the median carina, at the principal sulcus, 

 a slight oblique depression ; the whole pronotum broadens a little and 

 regularly in passing backward, the posterior margin obtusely and 

 roundly angulate; median carina distinct though slight on the meta 

 zona, inconspicuous excepting in front on the prozona, and in the 

 female nearly obsolete; lateral carinae distinct, though not prominent; 

 surface i)rofusely punctate, almost rugulose on the metazona; the color 

 is brownish-yellow, darkestou dorsum, and profusely tiecked with darker 

 colors; upper third or half of lateral lobes with a postocular brownish 

 fuliginous belt, contined to the prozona, narrower at the extreme front; 

 transverse sulcations distinct, only seldom, and then but slightly, 

 marked with black. Prosternal spine short and very stout, very blunt, 

 and subcylindrical (male) or conical (female); interspat*e between meso- 

 sternal lobes a little transverse (male) or half as broad again as long 

 but narrower than the lobes (female), the metasternal lobes approxi 

 mate (female) or only a little more than half as distant as the meso-
