the middle, concave behind, temples rounded; frons, vertex, and 

 temples coarsely rugoso-punctate, occiput more finely rugose; ocelli 

 in an obtuse triangle, the lateral ocelli about their own diameter 

 from the eye-margin; head viewed from in front somewhat broader 

 than long and subtriangular; eyes rather large, nearest each other 

 at insertion of antennae; face and cheeks with strong striae con- 

 verging at clypeus and covered with long white pile, the face not 

 broad, the distance between eye margins at insertion of antennae 

 much less than distance from antennae to apex of clypeus; cheeks 

 strongly carinately margined behind and sculptiu-ed like the vertex; 

 antennae inserted distinctly above the middle of front, the antennal 

 depression short and not deep; antennae 13-jointed; scape cylindri- 

 cal or nearly so, about four or five times as long as thick; pedicel 

 pyriform, a little longer than broad; one very inconspicuous ring- 

 joint: fourth antennal joint also veiy short, ringlike but distinctly 

 broader than the third and three or four times as broad as long; 

 fifth to tenth subequal and each slightly longer than broad; club 

 3-jointed, conic ovate, not or scarcely broader than the last funicle 

 joint, and about equal in length to the three preceding funicle joints; 

 thorax strongly gibbose, uniformly umbilicately punctate and clothed 

 with moderately long pale hairs on pronotum, mesoscutum, axillae 

 and scutellum; the surface between the punctures finely shagreened; 

 dorsal portion of pronotum about three times as broad as long at the 

 middle, the posterior margin slightly arcuate; mesoscutum about 

 one and one-half times as long as pronotum, the parapsidal grooves 

 complete but shallow; scutellum about as long as mesoscutum; 

 propodeum very coarsely reticulate-rugose, the spiracles large and 

 much longer than broad; mesopleura longitudinally striated below 

 and along the anterior margin, finely granular above, the posterior 

 portion more shining and with two or three irregularly formed areas 

 or reticulations; metapleura rugoso-punctate; coxae outwardly all 

 finely shagreened; hind tibiae with two subequal spurs, the hind 

 basitarsis nearly as long as four following joints; forewing irregularly 

 and sparsely ciliated behind the submarginal vein, more densely and 

 uniformly ciliated beyond, the costal cell also sparsely ciliated; mar- 

 ginal vein less than half as long as submarginal, about one-third 

 longer than stigmal, and very slightly shorter than postmarginal; 

 abdomen about as long and as broad as thorax, broadly ovate, broad- 

 est beyond the middle, narrowed at base, broadly rounded at apex; 

 first tergite subtriangular, nearly twice as broad at apex as long 

 down the middle; second tergite less than half as long as first, its 

 posterior margin weakly arcuately emarginate; third the largest ter- 

 gite, a little longer than first and second together; fourth about 

 equal to the second; fifth very short; sixth about as long as fourth; 

 seventh, except its margin, apparently concealed beneath the sixth;
