“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. Antenne 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 coxa, pale at base, piceous at tip. 
Pronotum polished, transverse, clothed with long, erect, dusky pile, re- 
motely punctate; the lateral margins oblique, with 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 acress the middle, and remote finer punctures in the 
impressed lines; pleurz pale, finely sericeous pubescent; sternum paler, 
bald, darker posteriorly; the impressed arc in front of the anterior coxe 
piceous. Coxe pale yellow; legs dark luteous, with dusky hairs; thighs 
somewhat pointed with brown; the tibiz 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, whicheare 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 there 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, 514-614 
mm. Width of base of pronotum, 14%-2 mm.
