half the width of the eye; ocell-ocular line about three times the 

 diameter of an ocellus; clypeus about twice as broad as long down 

 the middle and separated from the mandibles by a narrow trans- 

 verse opening; malar space about equal to the width of a mandible 

 at base; antennae 24-jointed in the type, the first flagellar joint 

 about five times as long as thick and distinctly longer than the 

 second; thorax smooth, the parapsidal grooves complete and deeply 

 impressed throughout; mesopleural furrow crenate; propodeum 

 rugose ; stigma of the f orewing broadly lanceolate ; recurrent nervure 

 interstitial; first abscissa of radius equal to about half the width of 

 stigma; second abscissa a little more than one and one-half times 

 the first transverse cubitus; radial cell extending to the extreme 

 apex of wing. First abdominal tergite about one and one-half 

 times as long as broad, broadening from base to apex and finely 

 longitudinally striate; following tergites smooth; ovipositor very 

 slightly exserted. Antennal joints beyond the fourteenth except 

 the two apical ones white, scape testaceous, rest of the antennae 

 brown; mandibles, palpi, and clypeus pale yellowish; face piceus; 

 remainder of the head black; thorax black; legs, including coxae, 

 pale stramineous; wings hyaline, veins and stigma pale brownish; 

 abdomen mostly black, the second tergite stained with yellowish.

OPIUS FUSCIPENNIS, new species. 



Female. — Length 3 mm. Head strongly transverse, mostly 

 smooth, the face below antennae sparsely punctate, vidth a distinct 

 median ridge; clypeus punctate, with the anterior margin nearl}^ 

 straight, about four times as broad as long down -the middle and 

 separated from the mandibles by a transverse opening; malar space 

 shorter than the width of a mandible at base ; posterior orbits about 

 two-thirds the width of the eye; ocell-ocular line equal to nearly 

 four times the diameter of an ocellus; antennse 38-jointed in the 

 type, inserted a little above the middle of the eyes, the joints unusu- 

 ally short, first flagellar joint a little more than twice as long as 

 broad, those in the middle scarcely longer than thick. Thorax 

 smooth; median impression of the mesoscutum slit like and extend- 

 ing two-thirds its length, parapsidal grooves deep anteriorly, but 

 effaced before joining the median impression; mesopleural impres- 

 sion strongly crenate; propodeum rugose, with a more or less distinct 

 irregular transverse raised hue before the middle; first abscissa of 

 radius equal to about two- thirds the width of stigma, which is broad ; 

 second abscissa of radius about one and one-third times the length 

 of the first transvei-so cubitus; radial cell terminating somewhat
