Figs. :W, 427, 428, 662 



This species bears a superficial resemblance to Megamelanus dor- 

 salis but the vertex is longer, narrower, the wings are more elongate, 

 brownish fuscous, spotted with white and the genitaliie are ditt'erent. 



Vertex very long and narrow, not as much narrowed anteriorly 

 as in the allied species; posterior margin nearly straight, median 

 carina extending for only about half tiie length of the vertex; lateral 

 carinas strongly elevated ; frons much narrowed above to the narrow 

 vertex, strongly produced to the median carina ; second segment of 

 the antenna? about twice as long as the first, subglobular. Pronotum 

 slightly shorter than the vertex, disk tricarinate, the lateral earinie 

 nearly straight and nearly parallel to the median carina. ^Mesonotum 

 tricarinate; median carina abbreviated on the scutellar portion; fore 

 wings elongate, narrow-, nearly five times a.s long as broad, parallel 

 margined not widened apically. INIale pygofer short, broad, the aper- 

 ture large, subtriangular ; genital styles broad; fiattening: the inner 

 margins nearly continguous for half their length on the base then 

 suddenly excavated, the apices obli(|uely truncate; the inner angles 

 produced nearly meeting; anal proces.ses short, blunt, incurved, nearly
