THEODORE H. FRISON O 



as scape; mandibles moderately punctate. Head abo\e antennae with a 

 slightly concave area, with numerous pvmctures of moderate size, limited on 

 each lateral margin by a row of large punctures and above by numerous 

 large punctures; behind ocelli coarsely punctate. Head viewed from above 

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

 in region of antcnnal fossae; viewed from the front with vertex slightly round- 

 ed, eyes oblitiuc, the distance between them noticeably greater below the 

 antennae than above; oceUi arranged in a triangle, lateral ocelli about twice 

 as far apart as distance from inner margin of eye, area between ocelH i)unctate; 

 setae sj^arse, pale. Antennae inserted far below middle of eyes, flagellum 

 davate, sixth flagellar segment twice as l)road as first or pedicel, setaceous; 

 scape over three times as long as distance from its articulation to inner margin 

 of eye, longer than pedicel and first two flagellar segments combined; pedicel 

 as long as first flagellar segment; second and third flagellar segments about 

 equal in length. 



Alitrunk somewhat less than twice as long as broad, about one-thinl longer 

 than high; with numerous pale setae, those on the dorsum and extreme 

 ventral ])ortions longest, short, dense and whitish on truncature. Pronotum 

 not forming a collar visililc from above, humeral angles rounded. Mesoscu- 

 f,um coarsely punctate, with slight, obliciuc imi)ressions indicating para{)sidal 

 grooves. Mesoscutellum impressed along cephalic margin with adjacent 

 large, deeply set punctures; remaining portion, except mesal part of caudal 

 margin, with large, more scattered punctures. Metanotum narrow, moder- 

 ately depressed, and coarsely punctate. Propodeum cephalad of articulation 

 of jietiole, except for a slightly elevated, ])olishcd, impunctate area at base of 

 petiole, with numerous large i)unctures. Mesoi)lcura with dorsal half, 

 sulcus and anterior swelling, except for very faint punctures, smooth and 

 polished; cephalodorsal angle with a shallow impressed basin; dorsal margin 

 with a row of irregularly shaped punctures. Metunapleura with ventral 

 area with large rounded punc-tures, sharjjly limited above by an obli(]ue 

 carina and a wide depressed sulcus; dorsad of carina two rows of elongate, 

 narrow^, somewhat irregular reticulations; dorsad of this latter an area of 

 large, more rounded reticulations. Truncature concave, reticulate. The 

 articulation of petiole somewhat dorsad of or vertical to mctacoxal fossae, the 

 mctimaplctu'a subquadrate in outline. Metastcrnal processes i arallel. 

 Posterior tibia and posterior tarsus setaceous, longitudinally aciculate; posterior 

 coxa i)unctate and setaceous on distal half. Outer jjosterior tibial spur slightly 

 longer than inner, less than one-half as long as the i)osterior metatarsus; pos- 

 teiior tarsus longcir than remaining tarsal segments together; tooth of claw 

 longer and stouter than apical ray. Wings liyaliiie; front wing with but one 

 closed cell, submedian vein lacking. 



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

 margin of propodeum; with distinct longitudinal carinae on lateral and dorsal 

 aspects; intervals between carinae with erect pale setae on dorsum, smoother 

 and more i)olishe(l on latus. Abdomen (compressed, smooth, polished and 

 impunctate.
