324 HETEROPTEROUS HEMIPTERA. 



head not extending more than half the length of the basal joint 

 of the antennae, obviously carinate between the antennae, tuber- 

 cles each side of the antennae; acute : antennas, first joint robust, 

 rough, much narrowed; second joint shorter than the third; ter- 

 minal joint half as long as the third : thorax, lateral margin a 

 little reflected, the edge concavely arquated; posterior angles 

 rounded ; anterior angles prominent, acute : scutel narrowed be- 

 fore the tip : hemelytra, corium yellowish, rufous near the scutel ; 

 nervures very distinct ; lateral edge a little reflected ; membrane 

 hyaline : beneath greenish-yellow ; feet pale rufous ; posterior 

 thighs dilated, spinous beneath. 



Length one-fourth of an inch. 



The rostrum hardly reaches the posterior coxae. The last joint 

 of the antennae is elongate-oval and much shorter than the pre- 

 ceding joint, as defined by Latreille in this genus. 



2. S. fraterculus. — Anterior point of the head extending 

 nearly to the tip of the first joint of the antennae. 



Inhabits Georgia and Indiana. [ 769 ] 



Closely resembles the preceding species, but is smaller; the 

 anterior tip of the head extends nearly or quite to the tip of the 

 first joint of the antennae; the lateral margin of the corium is 

 very distinctly punctured with black ; the membrane is marked 

 with a longitudinal obsolete brown line and small points ; the 

 general color is darker ; the tergum is sanguineous, black at base. 



Length less than one-fourth of an inch. 



A small specimen was sent to me by Mr. Oemler, from the 

 vicinity of Savannah, and I have obtained the two sexes in In- 

 diana. 



3. S. Obliqtjus. — All above punctured ; rostrum and head 

 rather short. 



Inhabits United States. 



Body pale yellowish-rufous : head obviously punctured, not ex- 

 tending to the tip of the first joint of the antennae ; antennae^first 

 joint robust; second hardly two- thirds as long as the third: 

 thorax with rather large punctures ; no obvious transverse im- 

 pressed line : hemelytra, on the corium with large separate 

 punctures ; posterior edge very oblique and elongated ; mem- 

 brane immaculate, undulated by the nervures : beneath more
