cave and contorted, as also the middle tibia, the latter with its inferior 

 margin seen from the front inflated medially ; middle tibia four-fifths 

 as long as the tarsus ; the metatarsus two-thirds as long as the remain- 

 ing segments united ; the fourth segment about as long as broad ; hind 

 tibia five-eighths as long as the tarsus ; metatarsus nearly equal to the 

 length of the remaining segments ; fourth segment longer than broad. 



Distance between r and R^ considerably less than that between 

 M3+4 and Mo on the margin of the cell R4+3. 



First dorsal segment, seen from above, with its basal surface plane ; 

 abdomen rather finely and closely punctate, superior processes of last 

 segment acute, the inferior, small, acute; surface between, somewhat 

 concave ; process of the third ventral segment with its summit ante- 

 riorly flattened. 



Squama exteriorly with only very short inconspicuous pubescence, 

 a small patch of setae within on the inferior margin ; sagitta trigonal, 

 long, slender, very acute, slightly curved ; uncus moderately slender, 

 slightly widened before the depressed and deflexed tip ; the latter 

 sharply acute. 



5. Colored as in the male except as noted; tip of the mandible 

 dusky ; labrum black ; yellow on clypeus confined to median bar and 

 two lateral spots ; only a spot on scape and third segment of antenna 

 yellow; humeral band confluent with spot below; pronotum. larger 

 apical stripe on scutellum, spot on posterior coxa and more of hind and 

 middle femora, yellow ; broader stripe on each dorsal segment, broad 

 apical stripe on second and fourth ventral segments, spots on side of 

 sixth ventral segment yellow. 



Hind ocelli little closer than their diameter's length from the com- 

 pound eyes ; front closely, rather coarsely punctate ; clypeus shagreened 

 with sparser, shorter, coarser, punctures. Humeri marked by a rather 

 sharp transverse ridge ; pronotum densely punctured ; mesonotum very 

 densely punctate; scutellum convex and densely punctate. IMiddle 

 femur with under surface flattened, its lower anterior margin marked 

 by a ridge ; middle tibia, seen from in front, with the basal third con- 

 tracted. Dorsal segments 2, 3, and 4 somewhat depressed basally ; 

 dorsal surface of the abdomen opaque, minutely, densely punctate.
