"Broad, ovate, dull ochreo-testaceous or clay-yellow, above clothed 

 with erect, moderately long, close, fuscous pubescence, which is longer 

 on the head and margins of the pronotum. Face longer, more oblique 

 and less vertical than in S. sphacelata, the front less prominently con- 

 vex, and the sutures not so distinct; vertex either dusky, or with a 

 small, black spot on the middle, and with a narrow black base; its sur- 

 face very flat and the eyes very large and prominent; the base of the 

 head forming a distinct neck, which is broader than the diameter in 

 front of the eyes. The tylus pubescent but the cheeks and gula bald and 

 whitish. Antennas long, dusky, beset with long, dark, hairs; the two 

 first joints clay-yellow; the basal one stout, short, a little thicker toward 

 the tip, second longest, feebly thickened on the extreme tip; third and 

 fourth scarcely thinner than the second, the fourth a little shorter than 

 the third, but not much longer than the basal joint. Rostrum reaching 

 near to the middle of the posterior coxae, pale at base, piceous at tip. 

 Pronotum polished, transverse, clothed with long, erect, dusky pile, re- 

 motely punctate; the lateral margins oblique, vvath the edge broad, thin, 

 recurved; the anterior angles blunt, but almost rectangular; the collum 

 slender but distinct, blackish; anterior lobe high, very convex, dusky in 

 front, and bordered by a deeply impressed, piceous line, having a few 

 coarse punctures acry>ss the middle, and remote finer punctures in the 

 impressed lines; pleurae pale, finely sericeous pubescent; sternum paler, 

 bald, darker posteriorly; the impressed arc in front of the anterior coxae 

 piceous. Coxae pale yellow; legs dark luteous, with dusky hairs; thighs 

 somewhat pointed with brown; the tibiae with a piceous tip and spines, 

 and the tips of the tarsal joints piceous, the nails paler piceous. Scutel- 

 lum a little convex at base, polished, pubescent, a little punctate on the 

 base and middle, which are also more or less infuscated, Corium broad, 

 pale luteous, closely, obsoletely punctate, erect, pubescent; the base of 

 costal margin expanded and broadly rounded, the costal area very wide, 

 the sutures and outer margin brownish; membrane paler, the nervures 

 long and rather straight, piceous, bounding five large areoles. Venter 

 highly polished, clothed with long, pale pubescence, minutely and obso- 

 letely punctate. The membrane is not conspicuously distinguished at 

 first sight from the corium, and the latter when held up to a strong 

 light appears flecked and dotted with brown. The disk of the venter is 

 occasionally a little infuscated. Male genital appendages apparently 

 like those of the preceding species. Occasionally thei'e is a series of 

 brown dots on the venter near the connexivum. 



"Length to tip of venter, 4-5 mm. Length to tip of membrane, BVz-GVi 

 mm. Width of base of pronotum, 1^4-2 mm.
