8 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



adjacent to the outer margin of the eye and row Hmiting lateral aspect of 

 head; malar space about cne- third as long as eye, about one-half as long as 

 scape, with scattered ccarse punctures; mandibles with a few faint puQctures 

 on proximal half, polished. Head above antennae very slightly concave, 

 with scattered punctures of moderate size; area behind ocelli with punctures 

 somewhat smaller than those below. Head viewed from above broader than 

 thorax, transversely subquadrate, about t-ftice as broad as long, but slightly 

 convex in region of antennal fossae; viewed from front with ocellar area not 

 noticeably elevated, eyes slightly oblique; oceUi arranged in a triangle, lateral 

 ocelli n.early three times as far apart as distance from inner margin cf eye; 

 with sparse, su])presscd pale setae. Antennae inserted very close together, 

 well below middle cf eyes, finely, densely setaceous, flagellum somewhat 

 clavate, tapering to distal end, last flagellar segment nearly twice as long as 

 any other flagellar segment; scape in length over three times the distance 

 froin its articulation to inner margin of eye, as long as pedicel and first two 

 flagellar .segments together; pedicel as long as first antennal segment; second 

 and third flagellar segments of about equal length. 



Alitrunk about one-third again as long as broad, about one-sixth again as 

 long as high; with numerous, suppressed pale setae. Pronotum not forming 

 a collar visible from above, humeral angles slightly angular. Mesoscutum 

 with a deep, somewhat rounded impression and a slight indication of parap- 

 sidal grooves on cephalic margin, lateral grooves indistinct, with well separated, 

 moderate-sized punctures. Mesoscutellum impressed along cephalic margin 

 adjacent to weak transverse suture with large rather deep ])unctures; re- 

 mainder of area with scattered moderately-sized jiunctures. Metanotum 

 narrow, with ])unctures of moderate size, except upon middle portion. Pro- 

 podeum ce])halad of articulation of i)etiole, excejit for a small, elevated, 

 polished, impunetate area at base of petiole, with numerous moderatelj' 

 sized punctures, abruptly limited laterally by reticulations of lateral aspect. 

 Propleura, except cephalad of tegulae, concave, polished, impunetate. Mes- 

 opleura, except for faintly punctate area ventrad of anterior swelling, im- 

 punetate, smooth, polished; cephalo-dorsal angle with a shallow, impressed 

 area; caudo-dorsal angle impunetate. Metunai)leura with a ventral moder- 

 ately punctate area, sharply limited above by an oblique carina and broad 

 depressed sulcus; sulcus impunetate, polished; dorsad of this latter an area 

 of large, irregular reticulations. Truncaturc slightly concave, finely, densely 

 setaceous; with a large carinately outlined, vertical, oblong reticulation 

 or (lei)ression dorsad of each metacoxal fossa, the space between them 

 somewhat concave, polished and impunetate; area just ventrad of articula- 

 tion of petiole reticulate. The articulation of petiole almost directly dorsad 

 of or vertical to metacoxal fossae, the metunapleura somewhat subquadrate 

 in outline. Metasternal i)rocesses slightly divergent at distal ends. Posterior 

 tibia and posterior metatarsus setaceous; posterior co.xa above with distal li;iir 

 punctured and wrinkled. Outer i)osterior tibial spur slightly longer than 

 imier, outer si)ur less than one-half as long as posterior metatarstis; postc^rior 

 metatarsus n(!arly a third again as long as remaining (arsal segments together; 

 (ooth of chiw not longcsr than .'i:|)ical ray. ^^'ings hyaline; front wings with 

 one closed subcostal cell, ni('(ii;in vein well formed.
