32 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERa) 



Evania mystica new species 



Mule. Lcnj;;th, 4.5 mm. 



Head, mesopleura, metathorax, propodeum, petiole, abdomen, middle and 

 hind legs, black. Pronotmn and mesonotum, ferruginous. Antennae and 

 fore legs fuscous. 



Head below antennae slightly convex; with punctures of moderate size, 

 except on polished cephalic margin of cly])eus; a small tubercle on face; with 

 a small furrow extending from near precoila about to articulation of antennae. 

 Malar space shorter than scape, about one-fourth as long as eye, with numerous 

 pvmctures of moderate size; occipital orbits broad, somewhat wider below 

 than above, portion adjacent to outer margin of eye with punctures of moderate 

 size, remaining portion polished; mandibles with proximal half finely punctate. 

 Head above antennae and behind ocelli with punctures of moderate size. 

 Head viewed from above much broader than thorax, transversely subquad- 

 rate, convex in region of antennal fossae; viewed from the front with eyes 

 nearly parallel; ocelli arranged in a triangle, lateral ocelli less than twice as 

 far apart as distance from inner margin of eye; with numerous golden setae, 

 most abundant below antennae. Antennae inserted rather close together, 

 below the middle of the eyes; scape over twice as long as distance from its 

 articulation to inner margin of eye, over three times as long as pedicel, not 

 as long as pedicel and first flagellar segment together; pedicel about one-third 

 as long as first flagellar segment; flagellar segments of nearly equal thickness 

 throughout, first and second segments nearly equal in length, third slightly 

 longer than either. 



Alitrunk nearly twice as long as broad, about one- third again longer than 

 high; with dense whitish setae on ventral parts and i)leura, dorsum with 

 sparse golden setae. Pronotum not forming a distinct collar visible from 

 above; humeral angles rounded, wrinkled. Mesoscutum with deep parap- 

 sidal grooves, lateral grooves weakly developed; area between parapsidal 

 grooves with scattered punctures of moderate size and minute punctures 

 intermixed; lateral lobes minutely punctate. Mesoscutellum separated from 

 mesoscutum by a transverse suture and an adjacent row of small punctures, 

 with many punctures of moderate size. Mctanotum narrow, well depressed, 

 reticulate. Proi)odeum above cephalad of articuilation of petiole reticulate, 

 except for a small, elevated, polished, impunctate area at base of petiole. 

 Propkiura concave, wrinkled. Mcsoi)leura with ventral portion, anterior 

 swelling and caudal portion of sulcus wi(h many shallow, rounded punctures 

 of moderate size; cephalic portion of sulcus polished and impunc^tate, except 

 for a small strip of minute punctures adjacent to propleura; cephalo-dorsid 

 angle impressed. Metunapleura with cephalo-dorsal angle finely punctate 

 and setaceous; ventral half with small reticulations, limited above by a very 

 narrow strip of small punctures; this latter area limited above by irregular 

 reticulations. Truncature slightly concave, with irregular sulxiuadrate 

 r('ti(;ulations and dense whitish setae. The articulation of the petiole far 

 cc'phalad of a line vertical to metacoxal fossae. Metasternal processes sligliily 

 divergent at distal entls. J'osterior coxa rugose above; jjosterior tibia with 

 aciculae arranged in irregular longitudinal rows among the numerous smaller
