Family MASARID^. 



Genus PSEUDOMASARIS Ashmead, 



PSEUDOMASARIS PHACELIiE, new species. 



Belongs in with texanus (Cresson), but is separated at once by the 

 eyes being separated at the vertex by a distance slightly greater than 

 the postocellar line (in texanus they are separated by much less than 

 the length of postocellar line). 



Male. — Length about 13 mm. Labrum obtusely pointed; cly- 

 peus strongly uniformly convex, arcuately emarginate in apical 

 middle, finely punctured; front with rather large, separate punc- 

 tures; scape not one and a half times as long as broad, third joint 

 distinctly shorter than fourth; anterior ocellus large, subreniform; 

 pronotum polished, with well-separated small punctures ; mesonotum 

 with distinct, well-separated punctures, which are somewhat closer 

 in the depressed area; mesopleurie and scutellum similarly punc- 

 tured; propodeum normal; abdomen polished, with widely sepa- 

 rated punctures which become smaller posteriorly; seen from above 

 the first dorsal is arcuately emarginate anteriorly; second, third, and 

 fourth dorsal segment depressed basally by about one-third the 

 length of the entire segment; processes of the third ventral and 

 apical segments essentially as in texanus; second cubital on the 

 radius slightly longer than the distance between the recurrent veins. 

 Black except where mentioned ; apical half of scape, fiagellum (except 

 apical spots on fourth and fifth joints and greater part of club), face 

 above level of antennte (tlie lower margin has three indentations of 

 black), most of clypeus, pronotum, large circular spot below tegulse, 

 tegulse, spot above, two fan-shaped spots on anterior part of meso- 

 scutum and a small spot in front depression, spot on scutellum and 

 angles of propodeum yellow; abdomen with broad dorsal and ventral 

 bands on apex of all segments reddish yellow (due in part to potas- 

 sium cyanide?); legs reddish -yellow, laiees yellowish; wings vitre- 

 ous, hyaline, slightly yellowish in stigmal region; venation pale 

 brown. 



Female. — Length about 12 mm. Labrum broadly rounded api- 

 cally; clypeus slightly convex, broadly arcuately emarginate teeth 

 bounding emargination large, very finely granular, with large punc- 

 tures intermingled; front with large, distinct punctures, which are 

 more widely separated on the eye margins and vertex; postocellar 

 line subequal with the ocellocular line; scape short, third joint of 

 antenna? as long as the three following; pronotum with well-sepa- 

 rated large punctures; mesoscutum with punctures the size of those 

 of pronotum, but they are much closer and especially so in the 

 depressed area; mesopleurre more closely punctured than the meso- 

 scutum; scutellum punctured like mesopleurse, with an indistinct
