28 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



length of pedicel and nearly equal to length of pedicel and first flagellar seg- 

 ment combined; second flagellar segment slightly longer than the first. 



Alitruidc nearly one-third longer than broad, somewhat longer than high; 

 with numerous golden setae, more dense and abundant on ventral portions. 

 Pronotum not forming a collar visible from above; humeral angles slightly 

 angular. Mesoscutum with deep parapsidal and faint lateral grooves; polished 

 and minutely punctate, except for a few large shallow punctures on cephalic 

 portion and adjacent to inner margin of parapsidal grooves. Mesoscutellum 

 separated from mesoscutum by a narrow transverse suture; disk polished, 

 impunctate excejit for a few large scattered punctures; lateral margins with 

 large and small punctures intermixed. Metanotiun narrow, wrinkled, 

 median portion not well depressed. Propodeum cephalad of articulation 

 of i^etiole minutely punctate, limited laterally by reticulations of lateral 

 aspect. Propleura obliquely concave; wrinkled and setaceous on ventral 

 portion, dorsal portion finely punctate. Mesopleura with dorsal portion of 

 sulcus and cephalic margin above polished, impunctate; anterior swelling 

 densely and minutely punctate; with a narrow, minutely punctate, setaceous 

 strip adjacent to interpleural suture extending to cephalo-dorsal angle; cephalo- 

 dorsal angle with several short longitudinal carinae and small punctures be- 

 tween carinae. Metunapleura with a ventral area of fine punctures below 

 and large, shallow almost reticulate punctures above; this area limited dorsally 

 by a short narrow polished impunctate area, in turn limited on dorsum by 

 irregular reticulations of propodeum. Truncature almost flat, irregularly 

 setaceous. The articulation of petiole nearly vertical to or dorsad of meso- 

 coxal fossae. Mesocoxal fossae and metacoxal fossae placed close together, 

 mesosternal processes nearly similar to the metasternal processes, which are 

 rather broad, divergent at distal ends and somewhat directed ventrad. Posteri- 

 or tibia and posterior metatarsus with numerous stout setae, and a few scattered 

 aciculae; posterior coxa above polished, minutelj^ ])un('tate and setaceous. 

 Inner posterior tibial spur over twice as long as outer, about two-thirds as 

 long as jiosterior metatarsus; posterior metatarsus about four-lifths of length 

 of remaining tarsal segments together; tooth of claw much longer and stouter 

 than apical ray. Wings hyaline, front wings with seven closed cells, sub- 

 discoidal vein in distal portion of front wing well chitinized and cubital 

 vein but weakly so. 



Petiole over twice as long as distance from ])()int of articulation to cephalic 

 margin of jjropodeum, polished, with but few punctures and setae. Abtlomen 

 compressed, i)olished, with munerous i)ale hair-like setae on dorsum of all 

 segments and lateral margins of apical segment s. 



One specimen, the holotype, collected May 4, 1920, at hiiii- 

 tos, Peru.
