18 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



region of antennal fossae; viewed from the front with ocellar area but sUglitly 

 elevated, eyes somewhat divergent below; ocelli arranged in a triangle, lat- 

 eral ocelli about twice as far apart as distance from inner margin of eye; with 

 numerous golden setae, more abundant and longer below antennae. Antennae 

 inserted close together and below middle of eyes, finely setaceous, flagellar 

 segments of about equal thickness throughout, scape finely punctate, in length 

 three times the distance from its articulation to inner margin of eye, as long 

 as pedicel and first flagellar segment together; pedicel about one-half as long 

 as first flagellar segment, slightly wider than long; second flagellar segment 

 longer than the first, third and second segments of nearly equal length. 



Alitrunk nearly three times as long as broad, nearly t%vice as long as high; 

 with numerous whitish setae. Pronotum not forming a collar visible from 

 above on the same plane as the mesoscutum, but with neck noticeably length- 

 ened; humeral angles rounded, finely punctate. Mesoscutum with distinct 

 pa rapsidal grooves; finely punctate along cephalic margin, remainder of area, 

 except for a row of small punctures adjacent to parapsidal grooves, polished 

 and impunctate. Mesoscutellum slightly convex, with scattered punctures of 

 moderate size. Metanotum narrow, coarsely sculptured. Propodeum ceph- 

 alad of articulation of petiole coarsely reticulate. Propleura finely pimctate 

 and striate. Mesopleura with dorsal half, except for irregular impressions in 

 cephalo-dorsal angle, somewhat pohshed and impunctate; anterior swelling 

 and ventral portion finely punctate; caudo-dorsal angle with several large 

 punctures. Metunapleura with a ventral coafsely punctate area, limited 

 above by a finely transversely-striate area which in tiu'n merges with a dorsal 

 irregularly reticulate area; with but a faint trace of the oblique sulcus. Trun- 

 cature reticulate, plainly convex, with numerous whitish setae. The articu- 

 lation of petiole far cephalad of metacoxafossae, nearly dorsad of or vertical 

 to mesocoxal fossae, the truncature gradually sloping off from above to meta- 

 coxal fossae and when viewed from the lateral aspect somewhat triangular in 

 outline. Metasternal processes rather long, slender and parallel. Posterior 

 tibia and posterior metatarsus with some rows of aciculae among the dense 

 setae; posterior coxa above rugose. Inner posterior tibial .spvu" somewhat 

 longer than outer, about one-third the length of posterior metatarsus; jjosterior 

 metatarsus longer than remaining tarsal segments together; tooth of ciaw 

 stouter but not longer than apical ray. Wings hyaline, front wings with 

 three closed cells. 



Petiole three times as long as distance fr.)ni ])oint of articulation to c(>phal](' 

 margin of propodeum, somewhat reticulate on lateral asi)ect, dorsum polished, 

 with several fine punctures, very sparsely setaceous. Abdomen compressed, 

 smooth and polished, with a few light-colored setae on caudo-dorsal margins 

 of segments.
