f\ Of medium size, brownish fuscous, often with a more or less feeble 

 ferruginous tinge, particularly in the female. Head a little prominent, 

 olivaceo plumbeous, above much infuscated, especially in a pair of wid- 

 ening stripes behind the lateral margins of the fastigium, and with a 

 piceous postocular stripe ; interspace between the eyes distinctly wider 

 than (male) or fully twice as wide as (female) the first anteunal joint; 

 fastigium strongly declivent, considerably (male) or shallowly (female) 

 sulcate, but variable; frontal costa just failing to reach the clypeus, 

 subequal, as broad as the interspace between the eyes, sulcate at and 

 below the ocellus, biseriately punctate above; eyes moderately prom- 

 inent in the male, not at all so in the female, much longer, especially 

 in the male, than the infraocular portion of the genae; antennae fer- 

 ruginous or luteo-ferruginous, often a little infuscated apically, about 

 four-fifths (male) or three-fifths (female) as long as the hind femora. 

 Pronotum feebly and rather regularly expanding posteriorly, the disk 

 faintly convex and passing by a well-rounded shoulder (somewhat 

 abruptly on the metazona) into the anteriorly tumid vertical lateral 

 lobes, the disk generally darker than the lower portion of the lat- 

 eral lobes (occasionally by a darker punctation) sometimes irregularly 

 marked with luteous, the upper part of the lateral lobes crossed by a 

 broad piceous band on the prozona, the lower portion more or less 

 closely copying the_^pjoring of the face but usually a little darker; 

 median carina slight, percufrent, a little (rarely much) less distinct on 

 the prozona than on the metazona; front margin subtruncate, very 

 faintly and very narrowly flaring, at least in the male; hind margin 

 obtusangulate, more obtusely in the female than in the male; prozoua 

 quadrate or feebly longitudinal (male) or feebly transverse, rarely quad- 

 rate (female), slightly or not longer than the closely but shallowly 

 punctate metazona. Prosternal spine rather large, appressed cylindrical, 

 very blunt, often niesially constricted a little, feebly retrorse; interspace 

 between inesosternal lobes nearly twice as long as broad (male) or a 

 little longer than broad (female). Tegmina (Plate I, fig. // ) almost invari- 

 ably surpassing, sometimes but slightly, more often considerably, the 

 hind femora, of moderate breadth, distinctly though very gradually 

 tapering, brownish fuscous, sometimes immaculate, sometimes sprinkled
