tibia, fulvous. Distal half of flagellum, distal two-thirds of hind tibia and 

 fenuir and dontes of mandibles, brownish. Abdomen, exelusive of tlio i)otiolo, 

 black. 



Head below antennae closely and moderately punctate, with a small tuber- 

 cle on face; lateral margins of clyi)eus somewhat carinate, but not distinctly 

 separating face from malar space; occij)ital orbits twice as wide below as above, 

 in widtli about one-half the length of malar space, with numerous fine punc- 

 tures; malar si)ace about one-fourth as long as eye, about one-half the length 

 of scape, with numerous fine punctures; mandibles weakly punctate. Head 

 above antennae nearly flat, coarsely punctate; area behind ocelh somewhat 

 punctate. Head viewed from above broader than thorax, transversely sub- 

 (juadrate, strongly convex in region of antennal fossae; viewed from the front 

 with ocellar area not elevated, eyes slightly oblique below; ocelli arranged in 

 a triangle, lateral ocelli less than twice as far apart as distance from inner 

 margin of eye; with short golden setae, most numerous below antennae. 

 Antennae finely setaceous, inserted close together and below middle of eyes, 

 with a faint inter-antennal carina, flagellar segments of nearly equal thick- 

 ness throughout; scajje over twice as long as the distance from its articulation 

 to iiiiii'r margin of eye, slightly less than as long as pedicel and first flagellar 

 segment together; ]5edicel about one-third as long as first flagellar segment; 

 first, second and third flagellar segments nearly equal in length. 



Alitrunk over a third longer than broad, one-seventh longer than high; 

 with numerous pale setae, most abundant on ventral portions. Pronotum 

 not forming a collar visible from above; humeral angles slightly angular. 

 Mesoscutum with distinct parajisidal and lateral grooves, the parapsidal 

 grooves much the deeper of the two; between parapsidal grooves with both 

 large scattered jjunctures and small punctures; lateral lobes mainly with small 

 punctures. Mesoscutellum with faint irregular, longituflinal striae, betwecTi 

 which are many irregular, coarse punctiu'es which often interrupt the striae. 

 Metanotum narrow, well depressed, with large subquadrate reticulations. 

 Propodeum cejjhalad of articulation of petiole coarsely j)unctate, limited 

 laterally by deeji reticulations of lateral aspect. Propleura concave, polisl.ed 

 below and finely punctate above. Mesoplcura with fore part of sulcus polish- 

 ed, imjjunctate; cephalo-dorsal angle with narrow, longitudinal depressions; 

 anterior swelling with large shallow' punctures, except for fine punctures 

 adjacent to i)ropleura; a row of large reticulations adjacent to interpleural 

 sul ure. \'ent ral area of metunapleura with large, shallow, scattered punctures 

 between which are many fine punctures, with an adjacent i)olished, narrow, 

 longitudinal dorsal area; this latter area limited above by irregular reticula- 

 tions; sulcus weakly developed. Truncature nearly flat, finely reticulate, with 

 numerous golden setae. The articulation of the petiole slightlj' cei)halad of a 

 line drawn vertical to or dorsad of metacoxal fossae; the metunapleura .some- 

 what subfiuadrate in outline. Metasternal processes with distal ends slightly 

 divergent; median coxae close together and with distal portion of mesosternal 

 processes divergent. Posterior tibia and posterior metatarsus with stout setae 

 and a very few scattered aciculae on the outer surface of posterior tibia:
