Madagascar (forest of East Perinet). 



AUied to 0. obscura Dist , but smaller and paler and distinguished 

 by the following particulars : the latéral margins of the pronotum 

 are sinuated, its humerai angles more expanded and reflected, the 

 scutellum is shorter with two black basai spots, the latéral margins 

 of the fourth abdominal segment are evenly rounded, those of the 

 last two segments straight, and the venter has no black granulation. 



In Ann. and Mag. of Nat. Hist (6) XI, p. 54 (1893) Distant gives 

 the following différences between the gênera Odontorhopala Stàl 

 and Para brachytes Dist. :

The différent degree in which the latéral expansion of the prono- 

 tal humerai angles is developed is, however, of no or little value 

 as a generic character in the Coreidse if not suported by other more 

 important characters, and there are many Coreid gênera containing 

 species wilh quite differently formed pronotal latéral angles. The 

 différence in the structure of the humerai processes between the 

 above described Delader anthracinus and 1). acuticosta Am. S. 

 (which are unquestionably congeneric) is not less pronounced than
