 hind part of pteropleuron black; metapleura above hind coxa exten- 

 sively black, this large spot separated from above-mentioned black parts 

 by^aftestaceous yellow narrow vitta extending forward over superior 

 margin of metapleura and sternopleuron; sternopleuron entirely black 

 except for narrow upper margin and separated from the black of meta- 

 pleura only by the yellow median coxa. Third and fourth abdominal

 very variable in size; fifth tergite with a pair of very large lateral black 

 spots separated by a testaceous yellow median vitta narrower than the 

 spots. Third to fifth tergites of female each with three variable black 

 spots; sixth tergite with a pair of lateral black spots and sometimes 

 with a median triangular third spot. Fifth tergite of male 1.7-1.8 times

 Pleura marked with two small dots: a circular one on sternopleuron and 

 an oval one on inferior part of ventral pleurotergite (latter may be 

 absent). Fourth and fifth abdominal tergites in both sexes each with a 

 pair of short, vittalike lateral black markings, third tergite with a p?ir of 

 small black w pale brown lateral dots; sixth tergite of female without 

 black markings. Ovipositor sheath slightly longer than breadth at base; 

 thorax only 2.4-2.5 times as long as sheath; apex of ovipositor lanceolate 

 with rounded tip and without minute dorsxl hook. Postpedicel long, 

 2.0-2.2 times as long as wide. Eyes in profile twice as high as wide. 

 Dorsocentral bristles inserted halfway between transverse suture and 

 supra-alar bristles. Maxillary palpi long-oval with long bristles on outer 

 margin. 5.8-7.3 mm. Panamd. . . . . cf 9 stonei, new species (p. 402) 



— Only dorsocentral and prescutellar bristles inserted on conspicuous shining
