except si)ot in front of tubercle; U-shaped discal mark and lateral 

 lines on scutum; fascia on posterior border of scutellum; narrow 

 fascia on posterior border of metanotum; curved fascia on dorsum 

 of propodeum; lateral angles of same; large triangular spot on 

 mesopleura; spot on metapleura; fasciae on tergites 1-5 all contin- 

 uous except the fifth ; first and second each inclosing a pair of dorsal 

 black spots; third and fourth each having a pair of anterior emar- 

 ginations; lateral spots on sternites 1-5; pair of conspicuous spots 

 on anterior coxae; femora, save a stripe above and a spot below on 

 each ; tibiae, save for a narrow stripe below on each ; and tarsi ;

The antenna is entirely black. Segments 6 and 7 of the flagellum 

 are slightly spinose on posterior border; 10 and 11 are excavated and 

 when seen from above are decidedly broader than the apical segment, 

 wliich is curved and roundly truncate at the apex. The inter- 

 mediate femora are dentate. The second sternite bears a small, 

 median, sharp-pointed process. The sixth bears a flattened, broadly 

 triangular, bluntly pointed median process and a pair of small, 

 pointed lateral processes. The seventh sternite is narrowed poster- 

 iori}' and is squarely truncate at the apex. The seventh tergite is 

 coarsely punctate and its posterior border is slightly notched or 

 sinuate on either side the midline. 



Allotype. — Black: labrum; mandibles, except tips; apical half of 

 the clypeus divided by a median dark line; spots below anterior 

 ocellus; posterior orbits; prothorax; U-shaped mark and lateral lines 

 on scutum; fascia on posterior border of scutellum enlarged at the 

 ends; fascia on posterior border of metanotum; prominent fascia 

 on dorsum and posterior surface of propodeum; lateral angles and 

 sides of propodeum; metapleura; broad triangular spot on meso- 

 pleura; broad continuous fasciae on tergites 1-A, the first bearing a 

 jmir or round anterior emarginations that are almost inclosed, second 

 and third each inclosing a pair of dorsal spots, fourth biemarginate 

 on anterior border ; pair of large lateral spots on fifth tergite ; lateral 

 spots on sternites 2-5; pair of conspicuous spots on anterior coxae; 

 femora, save for a line on each above and below; tibiae, save line on 

 each below; and tarsi; hright yellow. 



The antenna is wholly black. The sixth sternite is slightly carinate 

 along the midline and the punctures on either side this median area 

 are much coarser at the apex of the sternite than at the base. The 

 sixth tergite is roundly pointed at the apex and is thickly and 

 coarsely punctate, except along a narrow median line. The lateral 

 borders of the tergite bear numerous short, stiff spines. 



In this species the wings of the male are hyaline, those of the 

 female slightly and uniformly infumated. The pubescence is short
