t 



below white, the tarsi iiifuscated; pronotum, mesonotum, and tegul^ 

 rufous. Wings hyaline, iridescent; venation black. 



Claremont, California, Described from one female collected by 

 C. F. Baker. 



Perhaps this species is nearest to nevadensis (Cresson), but it is 

 readily separated by the black mesopleurse, as well as many struc- 

 tural differences. 



Type.— Cat. No. 14557, U.S.N.M. 



PARACHARACTUS NIGER, new species. 



Female. — Length 5.5 mm. Not very robust. Clypeus longer in 

 comparison to the length of the labrum than in any of the foregoing 

 species, its anterior margin truncate; third antennal joint longer 

 than the fourth, which is a little longer than the fifth; middle fovea 

 very elongate and extending a good distance above the insertion of 

 the antennae; antennal furrows distinct and parallel to the middle 

 fovea, not extending much higher on the head than the fovea; ocel- 

 lar basin entirely wanting; posterior orbits narrow; postocellar area 

 defined but not sharply so; head and entire thorax shining, almost 

 impunctate; claws with an inner tooth; venation as in leucostomus 

 except the stigma is angled at the base beneath; sheath rather robust, 

 straight above, rounded below. Color black; legs below knees brown- 

 ish; a very narrow margin of abdominal segments white. Wings 

 hyaline, hardly iridescent; venation black. 



Pasadena, California. Described from one female collected April

Type.— Ca.t. No. 14558, U.S.N.M. 



PARACHARACTUS CALIPORNICUS (Rohwer). 

 Neocliaradus californicus Rohwer, Can. Ent., vol. 41, 1909, p. 89. 



Type.— Cat. No. 14556, U.S.N.M. 



The original description is erroneous in stating ''nearer the base of 

 the claw is another small tooth." 



PARACHARACTUS NIGRISOMUS, new species. 



Male. — Length, 4 mm. Anterior margin of the clypeus very shal- 

 lowly, broadly, angulately emarginate, the surface convex, irregu- 

 larly punctured; supraclypeal foveas punctiform, not confluent with 

 the antennal foveas; supraclypeal area very short, gently convex; 

 ocellar basin and antennal furrows obsolete; middle foveas large, the 

 dorsal walls sloping; frontal foveas punctiform; postocellar area only 

 defined by punctiform foveas ; postocellar fine much shorter than the 

 ocellocularhne ; antennae short, stout, flagellar joints constricted basally, 

 the third antennal joint longer than the two follo^ving; scutellum punc- 

 tured like the scutum, lobe polished, impunctate; stigma short, angu- 

 late near base, tapering to apex; hypopygidium rather narrow, broadly 

 rounded apically; transverse median distinctly basad of middle of
