polished cephalic margin of clyjieus, with small punctures; face with a small 

 polished tubercle; with a small furrow extending from near precoila dorsad 

 to antenna! fossae. Malar space about one-half as long as scape, about one- 

 fourth as long as eye, with minute punctures; occipital orbits broad, much 

 wider below than above, polished and with numerous small [)unctures; mandi- 

 bles minutely jjunctured. Head above antennae nearly flat, with many 

 punctures of moderate size, with interantennal carina extending towards 

 median ocellus. Head viewed from above much broader than thorax, trans- 

 versely subquadrate, conspicuously convex in region of antennal fossae; 

 viewed from the front with eyes noticeably divergent, farther a]iart below 

 antennae than above; ocelli arranged in a triangle, lateral ocelli somewhat 

 farther apart than distance from inner margin of eye; with numerous short 

 golden setae, more sparse and longer behind ocelli. Antennae inserted rather 

 close together, slightly below middle of eyes; scape about four times as long 

 as distance from its articulation to inner margin of eye, five times as long as 

 pedicel, not as long as pedicel and first flagellar segment together; pedicel 

 about one-fifth as long as first flagellar segment; flagellar segments of nearly 

 equal thickness throughout, first and third segments nearly equal in length, 

 second slightly longer than eith(M\ 



Alitrunk about one-third longer than broad, somewhat longer than high; 

 with numerous golden setae, particularly on ventral jiortions. Pronotum 

 not forming a distinct collar when viewed from above; humeral angles angular 

 and wrinkled. Mesoscutum with deep i)arapsidal grooves, lateral grooves 

 but weakly indicated; median lobe with punctures of moderate and minute 

 size intermixed, lateral lobes with minute punctures dominant. Mesoscutellum 

 separated from mesoscutum by a deep transverse suture; with numerous 

 punctures of moderate size somewhat arranged in longitudinal rows. Meta- 

 notum narrow, not deeply depressed, coarsely sculiilured. Proijodeum 

 above cephalad of articulation of petiole with numerous, irregular, often 

 confluent ])unctures of moderate size, sharply limited laterally by large retic- 

 ulations of lateral aspect. Propleura concave, oblifjucly wi'inkled below and 

 with niiiiulc punctures above. Meso])Ieura witli vciilrnl portion, anterior 

 swelling and caudal half of sulcus with numerous shallow, rounded punctures 

 of moderate and minute size intermixed; ce])halic half of sulcus and area ad- 

 jacH'ut to propleura highly polished and impunctate, limited above by wrinkl- 

 ed impressed ceplu-do-dorsal angle and a strij) of large sub(|uadrate reticulations 

 and many minute punctures adjacent to interpleural suture. Metunapleura 

 with its ('ephalo-dorsal angle forming a- somewhat polished finely punctate 

 triangular area; sulcus feebly impressed, willi small p(ilisli(>d iiiipunclalc 

 area on cei)halic portion extending half \v;iy fidiii iiiiely ])iuictate triangular 

 area to metacoxal fossa; ventral portion and cauilal half of sulcus with large, 

 shallow, rounded punctures, donsad of sulcus willi large irregular reticulati.'ns. 

 Truncatiu'e nearly flat, reticulate setaceous. 'Hie articulation of pclinlc 

 (!ei)halad of a line drawn vertical to metacoxal fossae. Median coxae rather 

 close together and about one-half length of i)etiole removed from posterior 

 coxae, mesosternaJ ])rocesses more divergent at distal ends than met asternal 

 processes, metasternal pi'ocesses long antl divergent at dist;i! ends. Posterior
