24 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERa) 



posterior coxa coarsely punctate above. Inner posterior tibial spur twice as 

 long as the outer, two-thirds as long as posterior metatarsus; posterior meta- 

 tarsus three-fourths as long as remaining tarsal segments together; tooth of 

 claw much longer and stouter than apical ray. Wings hyaline, front wings 

 with seven closed cells, subdiscoidal vein in the distal portion of front 

 wing well chitinized and cubital vein but weakly so. 



Petiole robust, nearly three times as long as distance from i)oint of articula- 

 tion to cephalic margin of propodeum, with pronounced longitudinal carinae 

 and longitudinal rows of large irregular punctures on lateral and dorsal aspects. 

 Abdomen compressed, polished, with some pale setae on dorsal portion. 



Related in many ways to E. ditoma Kieffer, from Bolivia, but 

 differs greatly in size, comparative length of malar space, petiole, 

 etc. E. pulcherrima Szeplegeti, from Brazil and Peru, likewise 

 has many points in common with this species. 



One specimen, the holotype, collected April 2G, 1920, at 

 Yurimaguas, Peru. 



Evania delicata new species 



Male. Length, 3 mm. 



Head, dentes of mandibles, flagellum, ventral portion of mesopleura, meta- 

 pleura, propodeum, middle and hind legs, petiole and abdomen, black. Pro- 

 pleura, mesonotum, metanotum, tegulae and mesopleura above, ferruginous. 

 Scape, proximal jiortion of mandibles and distal portion of fore legs, pale 

 yellowish-brown. Tibial spurs yellow. 



Head below antennae slightly convex, cephalic margin of clypeus almost 

 impunctate, face finely punctate with a faint tubercle in middle; clypeus not 

 separated from malar space by an elevated carina, but partially so separated 

 by a short furrow extending from near precoila half way to the antennal 

 fossae; occipital orbits as wide above as below, shiny, finely punctate; malar 

 space about one-fifth as long as eye, longer than the pedicel, finely punctate; 

 mandibles minutely punctate and setaceous. Head above antennae feebly 

 convex, more strongly and densely punctured than below, punctures some- 

 what arranged in arcuate rows. Head viewed from abcjve broader than thorax, 

 transversely subquadrate, slightly convex in region of antennal fossae; viewed 

 from the front with eyes almost parallel; ocelli arranged in a triangle, lateral 

 ocelli twice as far apart as distance from inner margin of eye; with short 

 whitish setae, most numerous below antennae. Antennae finely setaceous, 

 inserted close together and below middle of eyes, with a faint interantennal 

 carina, flagellar segments nearly of equal thickness throughout; scajjc three 

 times as long as distance from its articulation to inner margin of (>ye, as long as 

 pedi(!('l and first flagellar segment together; pedicel about one-third as long 

 as first flagellar segment; scconil flagellar segment longer than either the first 

 or third segments, third flagellar segment kmger than the first. 



Alitrunk one-third longer (lian broad, as high as long; with numerous j)ale 

 setae. Pronotmn not forming a collar visible from above; humeral angles 

 somewhat rounded. Mesoscutum with tlistinct j)arapsidal anil very weakly
