24 HYMENOPTERA. 



and intermediate tibiae ; antennae dusky to pallid yellow ; eyes bright 

 pinkish red ; wings hyaline excepting the proximal halves of the fore 

 wings, that portion proximad of the distal end of the venation, which 

 is distinctly, though not pronouncedly fumated ; the fumated area ex- 

 tends to a point opposite the end of the stigmal knob and its distal 

 bounding line is nearly straight. Venation dusky. Body sculpture 

 inconspicuous. Colors of legs somewhat variable. Tegulae dusky yel- 

 lowish. 



Fore wings with short marginal fringes along the cephalic margin, 

 which gradually slightly lengthen along the apex, becoming twice 

 longer at the disto-caudal apex of the wing, then gradually shortening 

 again caudad and proximad ; the longest cilia are not more than an 

 eighth of the greatest wing width, which is near to, but not at the 

 apex. The discal ciliation is short and moderately close, arranged in 

 about from 16 to 20 lines across the widest portion of the wing. Mar- 

 ginal vein broad, straight, twice the length of the stigmal and nearly 

 a half shorter than the submarginal vein, truncate distad ; submarginal 

 vein narrow, straight, but distad where it curves cephalo-distad to 

 join the marginal, abruptly broader but not quite so broad as the 

 latter. Caudal wings normal, the blade moderate in width, acuminate, 

 the marginal cilia normal, those of the caudal margin as usual much 

 longer, here gradually lengthening distad where they are distinctly 

 longer than the greatest wing width, those of the cephalic margin 

 usual, short ; discal ciliation of the caudal wings consisting of three 

 longitudinal lines of cilia, the cephalic two paired, slightly converging 

 distad, originating at the apex of the marginal vein or nearly, the 

 caudal line slightly fainter, originating farther proximad, gradually 

 converging on the others toward the apex, nearer to, but not on, the 

 caudal wing margin. 



Antennas short and moderately stout, the club forming half of their 

 length, the scape short, not as long as the club, cylindrical, curved, 

 the pedicel shorter than the scape, not much longer than wide, conic 

 to subquadrate, subequal in length to the proximal club joint ; ring- 

 joint minute, flat, abruptly narrower than the pedicel or club ; the 

 three club joints distinct, the intermediate joint longest and widest 

 (base), the apical joint small, conic, acute; the club itself pointed conic- 

 ovate in shape. Pubescence of the antennae sparse, consisting of scat- 

 tered long hairs, mostly on the club.
