 brownish tinge, posterior angles with brownish black spots. Legs pale, with apices of femora 

 and tibiae tinged with red. Costal and anal margins of hemielytra black, with black punctures 

 on claval and anal areas. Abdomen dorsally, except connexival areas, tinged with red ; 

 venter pale ochraceous. Posterior margin of seventh abdominal tergum truncated, slightly 

 medially concave ; pygophore small with small posterior processes, posterior margin narrow, 

 about one-third of seventh abdominal tergum. 



o" genitalia : Claspers small, medially thick and rounded at apices (Text-fig. 76) ; dorsal 

 thecal appendages absent, ventral pair thin, medially curved and truncated at apices ; four 

 left lateral conjunctival appendages as in Text-fig. 77 ; frontal appendages paired, thin, short 

 and medially curved ; four right lateral conjunctival appendages as in Text-fig. 77, dorsal

Very similar to $ in general appearance ; posterior margin of seventh abdominal sternum 

 indented in middle, forming broad and truncated lobes on either side (Text-fig. 82). 



$ genitalia : First gonocoxae largely concealed by seventh abdominal sternum, outer 

 margin irregular with apices truncated ; intervalvular sacs absent ; spermatheca elongated, 

 tapering towards apex with smoothly curved neck and thick coiled tube.

This species is very close to S. phthisica (Gerstacker) and S. maculosa (Blote), but 

 can easily be separated from the latter by short rostrum and from the former by 

 short lateral black line, never extending beyond the collar. 



Stenocoris (Stenocoris) americana sp. n. 



(Text-figs. 85-87) 



Characterized by pale body, long rostrum, reaching beyond the second coxae and 

 by the form of <$ and $ genitalia.
