Thorax dorsally strongly shagreened and densely clothed with 

 rather long whitish hairs; scutellum about as broad as long, only very 

 slightly overlapping postscutellum, weakly sculptured and shining 

 behind the transverse furrow, the punctate marginal groove com- 

 plete; postscutellum practically smooth and with only a very weak 

 suggestion of a median carina; mesepisternum strongly sculptured; 

 mesepimeron not entirelj^ smooth; propodeum about half as long as 

 scutellum, with a moderately deep triangular median depression and 

 with the surfaces between this depression and the spiracular sulci 

 strongly rugulose; all coxae strongly sculptured; hind femur reticu- 

 lately aciculated, not especially broad, the ventral tooth acutely trian- 

 gular and located approximately at apical one-sixth of femur. 



Anterior wing extending a little beyond apex of abdomen; submargi- 

 nal, marginal, postmarginal, and stigmal veins in approximately the 

 proportions of 30, 13, 6, and 5, respectively; hind wing not quite at- 

 taining end of abdomen. 



Abdomen moderately compressed, rather finely and evenly reticu- 

 lately aciculate on sides; first tergite dorsally perfect^ smooth and 

 comprising about one-third length of abdomen; second tergite short, 

 sometimes entirely hidden dorsally beneath the first; third and 

 fourth tergites dorsally subequal and together a little longer than 

 first; fifth and sixth tergites subequal on dorsal line and together 

 about equal in length to the fourth, the sixth with numerous suberect 

 hairs laterally and with spiracles in rather shallow pits; ovipositor 

 about one-third as long as abdomen. 



Ty]^e locality. — Santiago de las Vegas, Cuba.
