Type (male). — Black: labrum; mandibles, except tips; clypeus, 

 except pair of large basal black spots; scape below; frons between 

 and above insertion of antennae, except pair of narrow vertical lines 

 between antennae; broad, short anterior orbits; posterior orbits nar- 

 rowed above; posterior border of pronotum; side of prothorax almost 

 entirely; spot on tegula ; small lateral spot on scutum at ^jase of 

 wings; small lateral spots on scutellum : fascia on anterior border of 

 metanotum not reaching its lateral margins; broad curved fascia on 

 dorsum and posterior surface of propodeum ; lateral angles and nearly 

 the entire sides of propodeum; metapleura ; mesopleui'a, except black 

 spot behind tubercle and another in front and above middle coxa; 

 mesosternum ; verj^ broad fasciae on tergites 1-6; fascia on first 

 tergite broadly and shallowly bisinuate on anterior dorsal margin and 

 more deeply and more acutely bisinuate on posterior dorsal margin; 

 .second and third fasciae each inclosing a pair of narrow, elongated, 

 elliptical dorsal black spots and somewhat irregular on dorsal margin; 

 fourth and fifth each biemarginate on anterior dorsal border and 

 slightly emarginate on posterior border at midline; sixth slightly 

 bisinuate on anterior border, slightly emarginate at midline on pos- 

 terior border, and shortened laterally; seventh tergite, except basal 

 lateral black areas; lateral spots on sternites 2-6; legs, except spot 

 below on posterior coxae, spot on all trochanters, line above on all 

 femora, line above and below on all tibiae, and spot below on each 

 segment of all tarsi ; pale or soiled yeJlowhh loklte. 



The flagellum is black and segments 8 and 9 are spinose. 

 Segments 10 and 11 are excavated below and are somewhat dilated. 

 Segment 12 is very slightly curved and is rather sharply pointed at 

 the apex. The frons between the antennae and to a less extent the 

 basal part of the clypeus are carinate. The anterior metatarsus is 

 provided with six spines, of which the proximal one is quite small. 

 The middle femora are weakly serrato-dentate. The process on the 

 second sternite is a low median carina ending posteriorly in a short 

 blunt point. The sixth sternite bears a low broadly triangular, 

 obtusely pointed process and the seventh is strongly carinate on the 

 midline. The seventh tergite, which is slightly sinuate laterally, 

 truncate apicall3% and slightly emarginate at apical midline, bears 

 short but evident lateral ridges. The wings are very slighth' but 

 uniformly infumated. The pubescence is short, dense, and gray on
