and a little longer than basal space between them ; apical margin slightly rounded. 

 Ulnar forked nearer apex than is the radial. Eyes together a little more than twice 

 as wide as vertex at base. Vertical Ibssette subquadrate rotundate, not longitudinally 

 carinate. Rostrum reaches well beyond apex of posterior coxae.

Similar in general appearance to O. kanakanus, but the tegmina are much broader 

 in proportion and more arched costally, costa notably thickened near the base. 



Black ; lateral margins of vertex, basal nervures (except costa) fuscous, the latter 

 with blackish granules ; apical nervures blackish-brown. Lateral margins of frons, 

 narrowly, basal half of rostrum etc. pale brownish-testaceous. Legs pallid, an irregular, 

 curved brownish band near apex of tegmen. Vertex much as in O. kanakaiius, one-halt 

 wider at base than an eye, about two-fifths longer than wide at base, which is 2^ times 

 as wide as apical margin. Forehead subquadrate, not carinate longitudinally. Rostrum 

 reaching beyond apex of posterior co.xae. Tegmen 2^ times as long as wide medianly.

Distinguished from other small species by the shorter, more parallel-sided vertex, 

 which does not (or scarcely) project beyond anterior margin of eyes. 



Black : lateral margins of vertex etc., apical margins of abdominal sternites etc. 

 pallid. Legs flavescent, longitudinally striped and marked with black (or only fumate) ; 

 scutellar keels ferruginous. Tegmina milky hyaline, nervures pale sordid flavous, 

 granules pale brown or black, hairs pale ; basal margin, a thin transverse line across the 

 middle, and a slightly undulate thin line from stigma to apex of clavus — brownish-black ; 

 transverse apical nervures fumate, nebulose ; costal area spotted. 



Vertex slightly wider basally than long, one-half longer than wide apically. Vertex 

 at base as wide as (or a trifle wider than) the eyes together, apically truncate. Forehead
