Genus OPHELTES Holmgren. 



Head behind eyes broad; eyes usually divergent below; clypeus 

 not separated, apex broadly rounded, not impressed; mandibles not 

 constricted at base, teeth equal and subacute; maxillary palpi very 

 long; malar space half as long as basal width of mandible; frons 

 deeply concave, flanked by sharp carinae; ocelli very large, sur- 

 rounded by a deep groove ; antennae as long as body, attenuate at 

 apex, scape subcylindrical, apex oblique; first flagellar joint nearly 

 twice as long as second, cylindrical; epomia present but short; 

 notauli deep anteriorly but becoming obsolete in middle of mesos- 

 cutum; prescutum with a weak median longitudinal ridge; scutel- 

 lum rather narrow, elevated in middle; mesopleurum with a broad 

 longitudinal impression, above which is a longitudinal welt; prepectal 

 carina reaching top of this impression and curving backward along 

 its dorsal margin; propodeum rather long, its posterior face short 

 and nearly perpendicular, its dorsal face strongly acutely elevated 

 near base, the closely approximate median carinae extending back- 

 ward from this point to the apical carina, latter very strong; spir- 

 acles large oval, directed laterally; hind basitarsus much shorter than 

 remaining joints combined; claws strongly pectinate; inner calcarium 

 fully a third as long as basitarsus ; wings large ; stigma very narrow, 

 radius near base; apical abscissa strongly curved, areolet pentagonal, 

 recurrent near apex; recurrent straight with bulla undivided; dis- 

 cocubitus curved, without trace of ramellus; nervulus post-furcal; 

 nerveUus broken above middle, reclivous; abdomen compressed from 

 base of third tergite; first tergite long, narrow, compressed at base, 

 glymmae confluent, spiracles slightly before middle; thyridia rather 

 large; seventh tergite not membraneous medially; ovipositor sheath 

 rounded at apex.
