20 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



petiole far ccphalad of mctacoxal fossae, nearly dorsad of or vertical to nieta- 

 coxal fossae, the truncature gradually sloi)ing off from above to rnetacoxal 

 fossae; metunapleura somewhat triangular in outline. Metasternal i)rocesses 

 slender, almost parallel throughout. Posterior tibia and posterior metatarsus 

 with longitudinal rows of aciculae among the demise setae; posterior coxa 

 above finely ])unctate. Inner poster or tibial spur longer than outer, a little 

 less than one-half the length of j)Osterior metatarsus; jiosterior metatarsus 

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

 and longer than aiiical ray. Wings hyaline, front wings with three closed 

 cells. 



Petiole three times as long as distance from point of articulation to cephalic 

 margin of propodeum, somewhat reticulate on lateral aspect, dorsum polished, 

 with a few scattered fine punctures, very sparsely setaceous. Abdomen com- 

 pressed, polished, with a few light-colored setae on dorsum. 



One specimen, the holotype, collected January 28, 1920, at 

 Teffe, Brazil. 



Brachygaster parish! new species 



Male. Length, 4 mm. 



Head above antennae, occipital orbits, ventral portion of mcsopleura, 

 metapleura, proi)odemn below articulation of petiole, petiole, abdomen and 

 hind legs, black. Face, mandibles, malar space, scape, pedicel, and anterior 

 legs, fulvous with dark discolorations. Pronotum, mesoscutum, mesoscutel- 

 lum, upper portion of mesopleura, metanotum, and })ropodeum above ceph- 

 alad of articulation of petiole, ferruginous. 



Head below antennae finely punctate; face with a small polished, elevated 

 tubercle and separated from malar space by a weak, polished carina; occipital 

 orbits much wider below than above, about as wide as length of scape, pblishcd , 

 with some minute punctures; lateral brims of antennal fossa strongly convex, 

 polished and extending down on face; malar space two-fifths as long as eye, 

 somewhat shorter than length of scape, polished, sparsely and finely punctate; 

 mandibles polished, with some small punctures. Head above antennae 

 almost flat, with numerous small punctures excei)t on median line; area be- 

 hind ocelli polished and impunctate. Head viewed from above slightly wider 

 than thorax, transversely subquadrate, twice as broad as long, somewhat 

 convex in region of antennal fossae; viewed from the front with occUar area 

 slightly elevated, eyes nearly parallel; ocelli arranged in triangle, lateral 

 ocelli twice as far ajiart as distance from inner margin of eye; with light- 

 colored setae, most abundant ami longest l)elow antennae. Antennae insert- 

 ed rather close together and below middk^ of eyes, finely setaceous, flagellar 

 segments of nearly e(jual thickness throughout; scaj^e over twice as long as dis- 

 tance from its articulation to inner margin of eye, shorter than pedicel and first 

 flagellar segnu^nt together; i)edicel about as thick as long, nearly one-third as 

 long as first flagellar segment; second flagellar segment nuicli longer than 

 first; third and second segments nearly e(|ual in length.
