anteriorly punctate in the male, the lateral margins moderately prom- 

 inent bnt rounded: frontal costa moderately broad, a little broader 

 than the basal Joint of the antennae, subequal, suleate below the ocel- 

 lus and sparsely i)un('tate; eyes moderately lar<;e, more prominent in 

 the nuile tlian in tlie female, about as loii^r as the infraociilar ]>ortion 

 of the genae, anteriorly truncate, especially in the fcnnde; antennae 

 a little more (male) or a little less (female) than half as long agj-hi 

 as head and ]»ron()tnm together, rronotuin subecpnil, in the female 

 feebly constricted in the mid<lle and shglitly broadened jmsteriorly: 

 metazona less than half as long as the i)rozona, the ])osterior sulcus of 

 the latter as distinct as the anterior which divides it in the middle, all 

 the sulci cutting the slight and equal median carimi; posterior mar- 

 gin truncave or very faintly and broadly emarginate: mesonotum fully 

 half (male) or distinctly less than half (female) as long as the meta- 

 notum. Interspace between the mesosternal lobes a little cuneiform, 

 about as large as (male) or a little larger than (female) the slightly 

 transverse lobes: interspace between the metasternal lobes much less 

 than half (male) or considerably more than half (t'enuih') the width of 

 the mesosternal intersi)ace. Fore and middle femora of male consid- 

 erably but not greatly intlated; hind femora slender, twice as long as 

 head and pronotum together. Abdomen lelatively slender, with a 

 sharp but slight median carina, the extremity scarcely enlarged in 

 the male (as viewed from above) and but gently ui>turned; supraanal 

 plate of male shield shai)ed, the i)roximal half of the ' ,<^eral nnirgius 

 ridged and the broad median sulcus margined with prominent ridges, 

 higher in the proximal than the distal half; furcula consisting of a 

 pair of small, moderately distant beads; cerci as long as the sujjra- 

 anal plate, subcouical, but tapering nuich more rapidly in the basal 

 than the apical half, the tij) very feebly down-curved: infracercal i)late 

 of either side large, suleate, much exposed, nearly meeting its mate, 

 and extending slightly beyond the supraanal plate. 



The body is brownish ochraceous, heavily banded with blackish 

 brown, the proi)ortions of the two varying simiewhat. The head 

 (excepting the vertex and a broad stripe behind the eyes which are 

 blackish brown) and the fore and middle legs are dirty ochraceous, 

 darker in the femah' +han in the niale, with an olivacecms tinge, and the 

 same color is foun< ^ whole under surface of the body and the lower
