EEVISIOIS^ OF THE GENUS EXETASTES CUSHMAN 257 



tarsi yellow; front wing yellowish hyaline with a broad fuscous 

 fascia basad of and another beyond stigma, the basal one darker; 

 stigma and veins in the middle hj^aline area yellowish, basal portion 

 of longitudinal veins reddish; hind wing almost uniformly pale fuscous. 



Type locality. — Sabino, Ariz. 



TVi^e.— U.S.N.M. no. 51794. 



Remarks. — Three females, the type dated August 17, 1921; the 

 others from Uvalde, Tex., September 1924, A. P. Dodd, and Tlahuililo, 

 Durango, Mexico, A. Busck. All are in bad condition, none having 

 a complete antenna or hind tarsus. The holotype is the best preserved 

 of the three.

Related to carinatifrons in the high interantennal carina, small 

 petiolate areolet, short second discoidal cell, and distinct petiolar 

 area, and differing from that species principally as follows: 



Female. — Length 9 mm, antennae 7 mm. 



Head thicker, with temples less strongly receding (about 45° to 

 longitudinal axis of body); frons less coarsely punctate and nearly 

 flat, clypeus with apical portion merely impressed, not infiexed, and 

 onh^ slightly shorter than basal portion; cheeks concave; malar space 

 a little shorter than basal width of mandible; mouth as broad as face; 

 occipital carina hardly reaching hypostomal carina, latter high and 

 thin; eyes very faintly convergent below; antenna 38- to 40-jointed, 

 rather stout, slightly tapering apically, second joint of flagellum 

 hardly twice as long as thick. 



Thorax less coarsely punctate, scutellum sparsely so; propodeum 

 somewhat more convex, petiolar area longer, reaching to about 

 apical third medially. 



Legs shorter, hind femur hardly surpassing apex of abdomen. 



xA.bdomen distinctly a little longer than head and thorax, stouter 

 vnih first segment thicker and second not longer than broad at base 

 ovipositor slender, slightly recurved, sheath about as long as first 

 tergite. 



Body and legs colored as in carinatifrons, but antennae blacldsh 

 apically; wings less contrastingly colored, but with same color pattern; 

 ovipositor sheath blackish. 



Male. — Like female except that temples are broader and rather 

 strongly convex; eyes a little smaller, the malar space consequently 

 about as long as basal width of mandible. 



Black markings larger; stemmaticum, spots on anterior margin of 

 mesoscutum and upper margin of mesoscutum, lateral areas of scu- 

 tellum and postscutellum, and meso-metathoracic suture also black.
