16 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



This species is named for my wife, who has helped me in the 

 typing of this and many other manuscripts. 



Brachygaster peruviana new species 



Female. Length, 6 mm. 



Head, mandibles, scape, pedicel, first three flagellar segments and proximal 

 half of fourth segment, thorax, propodeum, petiole and legs, fulvous or fer- 

 ruginous. Abdomen, exclusive of petiole, dentcs of mandibles and flagellum 

 distad of middle of fourth segment, black. 



Head below antennae, except for a bare interantennal line extending ventrad 

 of antennae, with many i:)unctures of moderate size; face separated from malar 

 space by a distinct, elevated, impunctate carina, which extends from near 

 upper angle of the base of mandible upward along inner margin of eye as far 

 as antennae; occipital orbits greatly constricted above and about one-half 

 as wide below as length of scape, polished, almost impunctate; malar space 

 somewhat less than one-third as long as eye, slightly less than one-third as 

 long as scape, with several small punctures; mandibles weakly punctate. 

 Head above antennae nearly flat, coarsely punctate, with punctures gradually 

 diminishing in size and number on vertex and occiput; area behind ocelli with 

 small sparse pimctiu'es. Head viewed from above broader than thorax, trans- 

 versely subquadrate, about twice as broad as long, noticeably convex in 

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

 elevated, eyes slightly divergent below; ocelli arranged in a triangle, lateral 

 ocelli about twice as far apart as distance from inner margin of eye; sparse, 

 golden setae. Antennae inserted rather far apart and far below middle of 

 eyes, finely, densely setaceous, clavatc from third flagellar segment, tapering 

 gradually again to distal end, ventral surface cf clavate segments rounded; 

 scai)e finely, densely punctate, in length five times distance from its articulation 

 to inner margin of eye, about the length of the pedicel longer than pedicel 

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

 segment, twice as long as wide; second flagellar segment not as long as pedicel 

 and first flagellar segment together, much longer than the thirtl. Antennal 

 fossae with lateral rims convex, polished, impunctate. 



Alitrunk twice as long as broad, about one-half again as long as liigli; willi 

 numerous goklen setae, most abundant ventrally. Pronctum forming a 

 very narrow collar visible from above, humeral angles roundetl. Mcsoscutum 

 with distinct parapsidal and latc-ral grooves; sparsely puncitate along cephalic 

 margin, remainder of area, except for a few scattered punctures much larger 

 than those cephalad, imi)uru;tate and polished. Mesoscutellum iini)ress('(l 

 along cephalic margin adjacent to transverse suture by a row of large sul)- 

 quadrate j)unctuics; remainder of an>a polished, with scattered punctures 

 of smaller size. iVIetanotum narrow, coarsely punctured. Propodeum 

 (cephalad of articulation of petiole with a few large, oblong punctures along 

 cei)halic margin, disk i)olished, limited laterally by reticulations of lateral 

 asi)cct. Propleura concave, finely punctate and slightly wrinkled cephalad 

 of attachment of front wing, minutely punctate and polished below. Mcso- 

 pleura with dorsal half ijolished and imjjunctate, except for two elongate,
