the eyes, reddish-orange, or pale red; antennss pale ferruginoas, the 

 second joint very short and slender, third fasiform, stouter, rather 

 longer than the fifth joint, fourth and fifth ovate, the fifth a little longer 

 than the fourth; rostrum pale ferruginous, reaching to the posterior 

 coxae, the basal joint with fine pubescence, second joint as long as the 

 third, curved, broad, compressed, ciliated with long bristles, third joint 

 compressed, a little wider toward the apex, carrying a very few shorter 

 bristles. Pronotum deeply sinuated to admit the head, the lunate im- 

 pression adjoining the anterior margin densely charged with coarse^ 

 deep punctures, which become less dense exteriorly ; the submargin 

 opposite the middle of the eye with a coarse puncture carrying a long 

 bristle; the lateral margins slightly oblique, curving inward at the an- 

 terior angles, beset with thirteen or fourteen coarse punctures, each car- 

 rying a bristle, the edge recurved ; posterior margin moderately arcu- 

 ated, very smooth, feebly scooped out next the humeri, the humeri a 

 little humped, the angles rectangular and a little rounded; transverse 

 dorsal line wide and deep, luna.tely impressed each side, charged with 

 rather remote, but very coarse, deep punctures, which scatter into 

 irregular series behind the line, aggregate each side, and are thence con- 

 tinued forward to a patch of denser and finer punctures behind the ante- 

 rior angles. Scutellum with remote, irregularly placed, coarse, deep 

 punctures, those of the exterior submargin denser, and almost in con- 

 tact with a marginal sutural series of denser and finer ones which ex- 

 tend not quite to the tip ; the base with an impressed line having close, 

 fine, dragged punctures; tip smooth, depressed, blunt, impunctate. 

 Legs pale ferruginous, the spines and tips of femora piceous, tarsi pale 

 yellow ; the anterior tibial teeth eight in number, the two basal ones very 

 slender, the others very stout and blunt. Corium highly polished, 

 coarsely distinctly punctured in the sutures, excepting the costal and 

 the one bounding the discoidal areole exteriorly ; the costal suture with 

 series of obsolete punctures, punctures becoming fewer and less coarse 

 posteriorly, behind the middle, exteriorly, to the tip almost impunctate; 

 costal margin scooped out at base, and from thence to the middle with 

 a series of six to eight coarse punctures, each carrying a bristle ; clavus 

 long and narrow, bounded at base on the inner margin with a single 

 series of distinct punctures, and on the outer margin beginning with a 

 double series, but continuing with a single series of punctures to near 

 the tip of the suture ; membrane pale, charged with about ten radiating 

 nervures. Disks of the episterna corrugated, dull, the outer section 

 areate and highly polished. Venter polished, paler than the upper sur- 

 face, ciliated on the lateral margin with long, remote bristles; base of 

 the first segment rastrated longitudinally each side; disks of the s33oad, 

 third, and fourth segments each with a series of remote, coarse punc- 

 tures bearing bristles; base a little inflated in the middle. 



Length 6.J-9 millimeters. Width of base of pronotum 4.^-5^ milli- 

 meters.
