(only 2 lateral spots on second segment of type), transverse band 

 occupying most of fourth ventral segment (in type 2 lateral and 2 

 median spots). 



Front closely punctured, clypeus closely and minutely punctulate, 

 with scattered larger punctures, posterior ocelli as far from each other 

 as from the compound eyes. 



Humeri rounded ; pronotum with well separated coarse punctures ; 

 mesonotum with close coarse punctures, posteriorly finer, closer and 

 less regular causing surface to be chagreened ; scutellum similarly punc- 

 tured but with coarse punctures more scattered ; pleura a little more 

 densely punctate than pronotum. 



Abdominal segments densely punctate at base, punctures finer to- 

 wards apex of abdomen ; second and third segments slightly contracted 

 at their bases. Length, 10 mm.

5- Black, the following parts straw yellow : spot on mandibles, 

 trilobed spot on clypeus, narrow line around the eyes, interrupted 

 below the incision, mesad of the summits and posteriorly below, tri- 

 angular spot on sides and narrow posterior border of pronotum, supe- 

 rior spot on pleura, tegulae, small spot near posterior border of meso- 

 notum, apical spot on scutellum, spot on angles of propodeum, apex 

 of front femora and extreme base of their tibiae externally, small spot 

 on apex of middle femora, spot at base of middle tibiae, lengthened 

 laterally, small anterior stripe at base of posterior tibiae, apical stripe 

 on each side of first and second tergite, preapical mesal stripe on same, 

 narrow apical border of third, fourth, and fifth tergites, incised later- 

 ally, broadly interrupted stripe of sixth tergite, preapical spots on 

 second and fifth, and apical bands on third and fourth sternites ; the 

 following parts burnt sienna: flagellum except base, all of legs except 

 yellow spots and bases of coxae, apical third to two-thirds of first three 

 tergites, excluding yellow portions, first and second sternites and trace 

 on third ; wings slightly smoky, slightly violaceous, the veins casta- 

 neous to black. 



Front closely punctured, punctures more sparse toward the eyes; 

 clypeus finely closely punctulate, the yellow spot indistinctly so. 

 Humeri rounded ; pronotum with separated punctures ; mesonotum 

 closely, granularly punctate, more finely on the fiattened posterior 

 part ; scutellum granularly punctate, more densely in the middle than 

 on the sides ; sides of propodeum mucronate, not carinate. Abdominal
