of the eyes; ocell-ocular line fully three tunes the greatest diameter 

 of an ocellus; thorax smooth and pohshed; propodeum rugose; 

 stigma of the forewing moderately broad and long; first abscissa of 

 radius about equal to half the width of stigma; second abscissa nearly 

 twice as long as the first transverse cubitus; recurrent nervure 

 interstitial or nearly so; first abdominal tergite rugoso-striate, broader 

 at apex than at base, without distinct sublateral carinao, but with a 

 sharp carina originating at each basal lateral angle and meeting on 

 the median line before the middle of the tergite; remaining tergites 

 smooth; ovipositor hardly extending beyond the apex of abdomen. 

 Head and thorax black; scape, mandibles, tegulae, legs including 

 coxae, and the venter and sides of abdomen bright reddish strami- 

 neous; dorsum of abdomen reddish brown, the first tergite black; 

 wings hyaline, the stigma yellowish, veins brownish.

OPIUS RUFOCINCTUS, new species. 



Allotypus rufodnctus Ashmead, MS. in Ent. News, vol 16, 1905, p. 297. 



Female. — Length 2.2 mm. Head strongly transverse; antennae 

 broken in the type, the first flagellar joint about three times as long 

 as thick; head above impunctate, the frons and vertex distinctly 

 hairy laterally; face closely punctate and covered with long hairs; 

 clypeus rounded on the anterior margin fitting close to the mandi- 

 bles and scarcely twice as broad as long down the middle; ocell-ocular 

 line about three times the diameter of an ocellus; posterior orbits 

 much narrower than the eye; malar space not equal to the width of 

 a mandible at base; mesoscutum faintly punctate and distinctly 

 hairy, the parapsidal grooves almost wholly effaced; mesopleurae 

 smooth except the impression which is ovate and crenulate; propo- 

 deum rugose with a distinct median carina; forewing considerably 

 longer than the whole body, broad; radius arising from about the 

 basal one- third of stigma which is not broad; first abscissa of radius 

 shorter than half the width of stigma; second abscissa about one 

 and two-thirds times the first transverse cubitus; second cubital ceU 

 narrowed toward the apex; recurrent nervure joining the first cubital 

 cell about the length of the first abscissa of radius before the basal 

 nervure; abdomen short, oval, not as long as the thorax, the apical 

 segments retracted; first tergite striate, narrower at base than at 

 apex, and a little longer than broad; following tergites smooth; 

 ovipositor scarcely reaching beyond the apex of abdomen. Black; 

 scape, pedicel, mandibles, except apices, palpi, clypeus, and all legs 

 including coxae pale honey-yellow; flagellum brownish black; tips 

 of mandibles and tarsal claws brown; apical one- third of hind tibae
