12 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERa) 



tions of those species in many ways, such as the comparative 

 length of the petiole, malar space, tibial spurs, punctuation, 

 etc. 



One specimen, the holotype, collected May 4, 1920, at Iquitos, 

 Peru. 



Hyptia fraudulenta new species 



Male? liength, 5 mm. 



Head in region of onelli, pedicel, flagellum, denies of mandibles, hind legs, 

 and abdomen, black. Remainder of head, mandibles, sca])e, thorax, fore 

 and middle legs, posterior coxa and posterior trochanter, ferruginous. Petiole 

 mainly ferruginous, but with a black suffusion above. 



Head below antennae with numerous punctures of moderate size, intervals 

 between punctures finely striated, tubercle on face very small; face separated 

 from malar .space by a smooth, elevated, impunctate ridge; occipital orbits 

 over twice as wide below as above, excej/t for a few, scattered, large punctures, 

 bare and polished; malar space over one-third the length of eye, two-thirds 

 the length of scape; mandibles with a few shallow punctures on proximal half, 

 polished. Head above antennae nearly flat, with punctures of same size as 

 those below, but somewhat arranged in arcs; area behind ocelli longitudinallj' 

 wrinkled and punctate. Head viewed from above broader than thorax, 

 transversely subquadrate, about twice as broad as long, but slightly convex 

 in region of antennal fossae; viewed from front with ocellar area elevated, 

 eyes slightly oblique; ocelli large, arranged in a triangle, lateral ocelli nearly 

 three times as far apart as distance from inner margin of eye; with sparse 

 golden setae. Antennae inserted below middle of eyes, densely, finelj^ se- 

 taceous, flagellar segments slightly bead-like or moniliform, the fovu'th flagel- 

 lar segment less than twice as broad as the first; scape with setae somewhat 

 longer and more sparse than those of flagellum, length nearly three times the 

 distance from its articulation to inner margin of ej^e, as long as pedicel and 

 first two flagellar segments together; pedicel about one-half as long as first 

 flagellar segment; second and third flagellar segments of ecjual length. 



Alitrunk about one-third again as long as broad, little longer than higli; 

 with numerous, golden setae. Pronotum not forming a collar visible from 

 above, humeral angles somewhat angular. Mcsoscutum without parai)sidal 

 or lateral grooves, with numerous, large, roundcnl i)unctures, those on the 

 very median cephalic margin smaller. Mesoscutellum impressed along 

 cephalic margin adjacent to transverse suture with large, deep, i)uncturcs; 

 remainder of area, except for a small, elevated, polished, imi)unctate area at 

 base of petiole, with moderate-sized punctures limited laterally by retic- 

 ulations of lateral aspect. Proi)leura mostly polished and impunctate. 

 Mesopleura with dorsal half imi)unctnte, i)olished; ccphalo-dorsal aniilc^ 

 with a shallow, impressed area; caudo-dorsal angle with a single, weak, 

 rounded puncture; ventral portion and anterior swelling sjjarsely and finely 

 punctate. Metunajjleura with a ventral coarsely i)unctate area, sharply 

 limited above by an oblique carina and a narrow depressed sulcus; suhnis
