30 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



polished, impunctate oblique area; ventrad of sulcus with rounded reticu- 

 lations of moderate size, dorsad of sulcus with reticulations larger and more 

 irregular than those below. Truncature slightly concave, reticulate, seta(;eous. 

 The articulation of petiole somewhat cephalad of a line drawn vertical to 

 n.etacoxal fossae. Median coxae widely separated and far removed from pos- 

 terior coxae, mesosternal processes short, widely separated and slightly diver- 

 gent; posterior coxae placed much closer together, metasternal process broad, 

 deeply cleft, outer margins slightly divergent. Posterior coxa above moderately 

 wrinkled and punctate, with numerous conspicuous, long, pale setae; posterior 

 trochanter and femur with many short pale setae and stiff, erect, bristle-like 

 setae intermixed; posterior tibia and posterior metatarsus with dense stout 

 setae. Inner posterior tibial spur twice as long as outer, half as long as posterior 

 metatarsus; posterior metatarsus much shorter than remaining tarsal segments 

 together; tooth of claw weakly developed. Wings hyaline, front wings with 

 seven closed cells, subdiscoidal and cubital vein in distal portion of front wing 

 not chitmized and but faintly indicated. 



Petiole over twice as long as distance from point of articulation to cephalic 

 margin of propodeum; coarsely, irregularly striate and punctate on dorsum, 

 obliquely- longitudinally striate on lateral aspect; conspicuously setaceous at 

 proximal end. Abdomen compressed, ];)olished, with numerous pale setae 

 on dorsum. 



One specimen, the holotype, collected January 2, 1920, at 

 Teff4, Brazil. 



Evania cerviculata new species 



Female. Length, 6.5 mm. 



Head, scajie, pedicel, flagellum beyond second segment, metapleura, pro- 

 podeum, proximal two-thirds of posterior coxa, ijroximal half of petiole, 

 abdomen, black. Prothorax, mesothorax, metanotum, ferruginous. First 

 and second flagellar segments, distal ends of median and i)osterior coxa and 

 proximal half of median and posterior trochanter, and distal half of j)etiok% 

 whitish yellow. Fore legs light brownish-yellow, middle and hind legs darker. 



Head below antennae slightly convex; with a distinct, sharply elevated, 

 polislunl, impunctate, V-shaped carina ventrally limiting the antennal basin, 

 the i)oint of V slightly extending ventrad on face; with numerous, oblong 

 punctures arranged in longitudinal rows; with a small furrow extending from 

 near precoila dorsad half way to antciunae. Malar spac^e about one-(hird 

 the length of eye, with numerous small punctures; occii)ital orbits very broa<l, 

 wid(!r below than above, with sparse i)unctures of moderate size and numer- 

 ous minute punctures; mandibles finely punctate. Head above antennae 

 with a sharp interantennal carina extending nearly to the median o(?ellus; 

 lateral brim of antennal fossa extending as a carina half way to ocelli, and 

 adjacent to outer edge of this carina, a longiludiiinl row of course punctures 

 extending to ocelli; intervals between carinae slightly conceive, densely, 

 finely i)unctate; area behind ocelli rather (ioarsely punctate. Head viewed 

 from above bi'otider than the thorax, transversely subciuadi'af c, sliglilly con-
