 it is placed in the key entirely on the basis of the original description. 



ORASEMA AENEA, new species 



Female. — Length 3.75 mm. Head and thorax strongly aeneous; 

 pleura, propodeum, and all coxae more or less metallic green mixed 

 with cupreous; abdomen varying from mostly fuscotestaceous with 

 a metallic tinge to mostly metallic green, usually more or less brown- 

 ish testaceous basally becoming darker toward apex, but occasionally 

 almost entirely metallic green ; mandibles, scape, pedicel, tegulae, and 

 legs, except their coxae, testaceous; antennal flagellum black; eyes 

 and ocelli reddish ; wings hyaline, venation brownish testaceous. 



Head and thorax strongly sculptured, the vertex, mesoscutum, axil- 

 lae and scutellum rugoso-punctate without any alveolate punctures; 

 punctation of head below vertex, mesopleura, and coxae finer and 

 more or less alveolate; metanotum rugose; propodeum medially and 

 along its anterior and posterior margins rugose, the remainder of its 

 surface, except in the rather broad and deep spiracular grooves, finely 

 alveolately sculptured; abdominal petiole rugoso-punctate and 

 usually with about three longitudinal rugae medially ; gaster entirely 

 polished. 



Antenna long and slender, not clavate; scape not quite attaining 

 anterior ocellus; pedicel about as broad as long; ring joint transverse; 

 flagellum not thicker than pedicel, its joints all longer than broad, 

 the first joint about twice as long as broad, the second subequal to 

 first, and the following joints successively decreasing slightly in 

 length. 



Head, viewed from in front, broader than long; malar space sub- 

 equal to the height of eye, with a shallow longitudinal depression; 

 clypeus broader than long, uniformly sculptured, clypeal f oveae deep ; 

 supraclypeal area a little longer than broad, about as long as clypeus 

 and similarly sculptured; ocellocular line shorter than postocellar 

 line; lateral ocellus about twice its diameter from eye margin. Scu- 

 tellum with a shallow depression medially, without distinct grooves 

 on the sides and with the transverse fold often obscured by the rough 

 sculpture; mesepimeron with its dorsal half, except for a small area 

 on its lower margin, sculptured like the lower half. 



Forewing behind submarginal vein not entirely bare; costal cell 

 with numerous nearly uniformly distributed cilia; stigmal vein 

 longer than broad ; postmarginal vein fully half as long as marginal. 



Abdominal petiole about one and one-fourth times as long as 

 broad, distinctly shorter than hindcoxa.
