INVESTIGATIONS ON THE MUTELLID WASPS 193 



coarsely, confluently punctate throughout; vertex and genae with 

 the punctures less coarse and mostly contiguous, rather than con- 

 fluent ; relative widths of head and thorax T.5-9.5. 



Thorax black, somewhat tinged with red, sparsely clothed through- 

 out with long, erect, black pubescence; junction of the cephalic face 

 and dorsum of pronotum rounded ; pronotum, mesonotum, scutellum 

 and metanotum coarsely, confluently punctate, appearing rugoso- 

 punctate; propleura with large coarse punctures anteriorly, inter- 

 mixed coarse and fine punctures posteriorly ; mesopleura with coarse 

 contiguous punctures intermixed with very small, fine punctures; 

 metapleura glabrous, impunctate except for a few large scattered 

 punctures on the ventral third; metapleura clothed with sparse, 

 short, blackish pubescence; sides of propodeum with very large, 

 coarse, contiguous punctures, almost foveolate; posterior face and 

 dorsum of propodeum very coarsely, deeply and irregularly foveo- 

 late; tegulae glabrous, impunctate except the cephalic third and 

 inner lateral margin with very close, coarse punctures, the punctate 

 area bearing long, coarse, black hairs. 



Abdomen black, except the first and second segments ferruginous; 

 first tergite very broad at the apex and strongly constricted sub- 

 apically; disk of first tergite glabrous, with a few scattered punc- 

 tures, laterally and apically with coarse, confluent punctures, sparsely 

 clothed throughout with very long, erect, black pubescence; second 

 tergite with small, slightly elongate punctures, separated by from one 

 to two times their own diameter; narrow lateral margins of second 

 tergite glabrous, impunctate, bare; second tergite sparsely clothed 

 with very long, erect black pubescence, except a pair of obscure sub- 

 apical spots on the disk with the pubescence ferruginous, and moder- 

 ately thick apical fringe of long, black hairs ; tergite 3 ferruginous ; 

 tergites 4r-Q black; tergites 3-6 with moderate, close punctures, 

 sparsely clothed with long, erect, black pubescence ; ultimate tergite 

 punctate and pubescent at the base, the pygidial area distinct and 

 bare, slightly longitudinally rugose ; first sternite with a prominent, 

 longitudinal, median carina, very coarsely, confluently and deeply 

 punctate, sparsely clothed with very long, black pubescence; second 

 sternite with a median, very elongate, ovate pit, densely filled with 

 ferruginous pubescence ; remainder of sternite with distinct, elongate, 

 moderate punctures, sparsely clothed with erect, black pubescence; 

 sternites 3-6 densely, closely punctate at the apical margins ; ultimate 

 sternite with moderate, shallow, separated punctures; sternites 2-6 

 with a thin, apical fringe of long, black hairs. 



Wings dark fuliginous; cell 2nd E^ + Ra broadly truncate at the 

 apex ; cell R4 almost obsolete ; vein M3+4 received by cell II5 one-third
