tate, the portion immediately posterior to the carina confluently punc- 

 tate ; clypeal fringe of long, pale yellow pubescence ; antennal tuber- 

 cles distinctly separated; scape long, curved, indistinctly punctate 

 with shallow punctures, sparsely clothed with silvery pubescence; 

 first segment of flagellum twice as long as it is broad at the apex, not 

 as long as segments 2 and 3 united ; antennal scrobes carinate above ; 

 front and vertex confluently punctate, the genae with close contigu- 

 ous punctures; front and vertex densely clothed with appressed 

 golden pubescence and scattered, erect, pale hairs; the genae with 

 sparse, appressed, silvery pubescence; postero-lateral angles of the 

 head distinctly carinate, the carina somewhat crenulate; relative 

 widths of head and thorax, 6.5-5.75. 



Thorax ferruginous, pyriform; dorsum confluently foveate, the 

 fovea becoming larger and more distinct on the propodeum, the dor- 

 sum and posterior face of the latter broadly reticulate, except the 

 disk of the ventral half of the posterior face of the propodeum gla- 

 brous, microscopically punctate; dorsum sparsely clothed with ap- 

 pressed, silvery pubescence excepting an obscure median transverse 

 spot where the pubescence is black ; a spot of somewhat denser silvery 

 pubescence on the disk of the propodeum; scutellar scale entirely 

 absent; anterior margin of propleura defined b}^ a sharp carina ex- 

 tending from the ventral margin to the humeral tubercle; propleura 

 finely punctured, with a- few large scattered punctures, somewhat 

 densely clothed with appressed, silvery pubescence; anterior half of 

 mesopleura very finely punctate, sparsely clothed with appressed 

 silvery pubescence; posterior half of mesopleura with large, confluent 

 punctures, sparsely clothed with appressed, silvery pubescence and 

 scattered, erect, pale hairs; metapleura with coarse ])unctures along 

 the ventral margin, elsewhere indistinctl}", finely punctate, somewhat 

 densely clothed with appressed, silvery pubescence; sides of propo- 

 deum glabrous, impunctate except near the posterior margin, where 

 the reticulations extend over from the posterior face. 



Abdomen ferruginous; first tergite deeply, foveately punctured 

 posteriorly, glabrous, more or less impunctate anteriorly, with a 

 slight, median, longitudinal depression, the latter finely punctate; 

 clothed with scattered, long, erect, pale hairs, and a median apical 

 spot of dense, appressed, silvery pubescence ; narrow lateral areas at 

 the base of the second tergite glabrous, impunctate; remainder of the 

 tergite with dense, confluent punctures, the latter somewhat larger 

 and more separated toward the lateral margins; second tergite with 

 a large, subrounded, basal, median spot, connected with a narrow 

 subapical band which merges with the apical fringe subdorsally, all 

 of sparse, appressed, black pubescence; the apical fringe medially 

 and laterally silvery, black each side subdorsally ; remainder of tergite
