As thus typified, Zonocryptus falls within the limits of Oneilella 
Cameron as treated by Watersten*. In Waterston’s key to males 
the above-mentioned specimen runs to rufopetiolata Waterston, but 
disagrees with most of the characters in the formal description of 
that species. It does agree in the form of the areolet as described 
in the key to females. 
It seems likely that Onedlel/a as treated by Waterston is a com- 
posite genus, a possibility suggested by Waterston himself. If such 
proves to be the case, Zonocryptus would include those species in 
which the sides of the areolet converge toward the radius with the 
first intercubitus much more oblique than the second. Too little 
material of the group is before me to justify the synonymizing of 
Oneilella with Zonocryptus or the transferring of any species from 
the one to the other. 
ZONOCRYPTUS SPHINGIS (Ashmead) 
Male—tLength 14 mm. 
Head polished, impunctate except finely and sparsely so on face; 
temples strongly convex, nearly as broad as eyes anteriorly; inner 
margins of eyes convexly curved, frons broadening dorsally and 
face ventrally; frons deeply concave, but not carinately bordered 
laterally; face slightly elevated medially; clypeus strongly convex 
in middle, its apical slope steep and with a blunt tooth; malar space 
three-fourths as long as basal width of mandible; mandible twice 
as broad at base as at apex, finely and irregularly rugulose, upper 
tooth longer and more acute than lower tooth; second joint of 
maxillary palpus broad and nearly parallel-sided; with a rounded 
protuberance on apical exterior angle; antenna (both broken) with 
first joint of flagellum nearly a half longer than second joint, others 
gradually diminishing in length, subapical joimts transverse. 
Thorax punctato-rugose laterally, polished and virtually impunc- 
tate dorsally; mesoscutum with a low, median, triangular elevation 
anteriorly, notaulices fine and shallow; scutellum sloping nearly from 
base, subacute at apex, fovea deep and bounded laterally by very high 
carinae; propodeum coarsely reticulate-punctate, basally nearly 
smooth, and apical slope irregularly rugose, spiracles elongate oval; 
pronotum smooth above, obliquely striate in scrobe; speculum pol- 
ished, prepectoral carina incomplete above, sternaulices short and 
broad. Wings broad; stigma narrow with radius basad of middle; 
basal vein straight; ramellus very short, the two abscissae of disco- 
cubitus straight; areolet small, pentagonal, higher than long, inter- 
cubiti strongly convergent, the first much more strongly oblique than
