82 PROCEEDINGS OF THE NATIONAL MUSE I M. VOL.XX. 



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

 inent but rounded 5 frontal costa moderately broad, a little broader 

 than the basal joint of the antennae, subequal, sulcate below the ocel- 

 lus and sparsely punctate; eyes moderately large, more prominent in 

 the male than in the female, about as long 'as the infraocular portion 

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

 a little more (male) or a little less (female) than half as long again 

 as head and pronotum together. Pronotum subequal, in the female 

 feebly constricted in the middle and slightly broadened posteriorly: 

 metazona less than half as long as the prozona, the posterior sulcus of 

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

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

 gin truncate 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 inetasterual lobes much less 

 than half (male) or considerably more than half (female) the width of 

 the mesosternal interspace. Fore and middle femora of male consid- 

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

 head and pronotum together. Abdomen relatively slender, with a 

 sharp but slight median cariua, the extremity scarcely enlarged in 

 the male (as viewed from above) and but gently upturned; supraaual 

 plate of male shield shaped, the proximal half of the lateral margins 

 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 supra- 

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

 than the apical half, the tip very feebly down-curved ; iufracercal plate 

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

 and extending slightly beyond the supraanal plate. 



The body is brownish ochraceous, heavily banded with blackish 

 brown, the proportions of the two varying somewhat. 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 female than in the male, with an olivaceous tinge, and the 

 same color is found on the whole under surface of the body and the lower 

 half or less of the lateral lobes of the pronotum ; the broad dark band 

 behind the eyes continues across the upper half of the lateral lobes 

 and the whole of the abdomen, bordered above by an ochraceous stripe, 

 which begins between the eyes, bordering their upper margin, and con- 

 tinues to the end of the abdomen, often becoming duller in color as it 

 approaches the extremity and is more narrowly separated from its 

 mate; sometimes the intervening dark stripe, which occupies most of 

 the vertex of the head, and is always broader anteriorly than posteri- 

 orly, is interrupted at the metazona and on the meso- and metanota, so 

 that the lighter bands here unite. Hind femora varying from brownish
