8 PROCEEDING OF THE NATIONAL MUSEUM vol. w 



the median carina that terminates about two-thirds of the distance 

 to the apical margin. 



Female. — Length 16-22, forewing 10-13 mm. Head red except 

 tip of mandible, antenna, and hypostomal area; thorax, legs, and 

 abdomen black, the latter with blue reflections; wings moderately 

 infumated, more strongly so on outer two-thirds of forewing, and 

 with violaceous reflections. 



Head from above with length (apex of antennal insertions to 

 occiput) about five-sixths (0.83-0.84) the width across eyes; clypeal 

 keel weak, present only on upper two-thirds, the median teeth on 

 apical margin also weak; median sulcus on front extending halfway 

 to anterior ocellus; lower half of front with coarse, contiguous punc- 

 tures arranged in longitudinal rows, the upper half with scattered 

 coarse punctures; vertex punctured about as upper half of front; 

 ocellocular distance 2.78-2.88 times the postocellar distance and 

 0.55-0.67 times the ocelloccipital distance; anterior ocellus about as 

 close to apices of antennal tubercles as to occiput; head beneath 

 with posterolateral angles rounded; distance between occipital and 

 hypostomal carinae about half the length of hypostomal area. 



Anterior margin of pronotal disk with a strong ridge, anterior 

 half of disk with coarse, subconfluent punctures arranged in longi- 

 tudinal rows, the posterior half with more scattered smaller punc- 

 tures; scutum with moderately large, subconfluent punctures except 

 posteriorly in middle, where they are confluent; scutellum with 

 punctures more evenly distributed; mesopleural disk produced ante- 

 riorly in middle beyond concave anterior face of sclerite, the punc- 

 tures mostly coarse and mostly separated by less than the diameter 

 of a puncture, slightly sparser than in shuckardi; punctures adjacent 

 to cuneate space on dorsum of propodeum small, more closely grouped 

 there than on anterior two-thirds of disk, and with larger, subcon- 

 fluent pits posteriorly and posterolaterally ; posterior propodeal surface 

 with coarse pits that are confluent in irregular, transverse rows, and 

 with the rows separated from each other by about twice the diameter 

 of a pit. 



Disk of first tergum weakly ridged anteriorly; last tergum sha- 

 greened at extreme apex. 



Inferior margin of hind femur rounded at middle; hind tibia at 

 apex on inner surface with four short, flattened setae. 



Male. — Unknown. 



Specimens examined. — 1 9, Sar. [Sarawak] (HMOU, the holotype). 

 2 9, Sandakan, Borneo (USNM, Baker Collection).
