64 HYMENOPTERA. 



Fore wings nearly as broad as in aniericana broader than those of 

 suMasciata as figured or of sanguinea, the longest marginal cilia dis- 

 tinctly shorter than the greatest wing width which is a little more than 

 half way distad of the distance between the stigmal knob and the wing 

 apex; whereas in subfasciata as figured and sanguinea the longest 

 marginal cilia are about equal to the greatest wing width which is still 

 more than half way distad between the stigmal knob and the wing 

 apex ; in ainericana these arrangements are very similar to those de- 

 scribed for this species, but the fore wings are still broader in relation 

 to the length of the longest marginal cilia. Discal ciliation of the fore 

 wing somewhat as in aniericana but somewhat less conspicuous, the 

 individual cilia somewhat smaller, the whole consisting of about nine 

 longitudinal lines across the widest portion of the wing ; the discal 

 ciliation extends back to the stigmal knob, to a point caudad of it, and 

 proximad, caudad of the marginal vein, at its center nearly, in the 

 center of the wing, is a longitudinal row of three or four cilia. Mar- 

 ginal cilia longest disto-caudad, on the caudal wing margin extending 

 around to a point slightly proximad of a point opposite (caudad) the 

 stigmal vein. Posterior wing normal, acute at the end of the mar- 

 ginal vein where three booklets arise, its blade acuminate, bearing one 

 principal line of discal cilia extending the whole length of the blade, 

 nearer to the cephalic than to the caudal margin and as usual the line 

 of discal cilia arising near the cephalic margin between the bases of the 

 marginal cilia ; this line of cilia is not, however, directly at the cephalic 

 margin and is minute and inconspicuous ; it is not present along the 

 caudal margin of the wing (^-inch objective). Marginal cilia of the 

 posterior wing minute, uniform, inconspicuous on the cephalic margin, 

 as is usual, but at the wing apex and along the caudal margin very 

 long, longest at the center of the caudal margin, nearly as long there 

 as twice the greatest wing width and nearly as long as the longest mar- 

 ginal cilia of the fore wing. Venation normal to the genus, the long 

 straight marginal vein subequal to or slightly longer than the submar- 

 ginal vein, the short rounded stigmal vein nearly sessile, the knob 

 rounded, thickened and with a small usual uncus. Postmarginal vein 

 absent. 



Legs normal, the proximal tarsal joint subequal to the distal joint of 

 the tarsus, the intermediate joint somewhat shorter. Tibial spurs of 

 intermediate and posterior legs minute, in the first apparently single, 

 straight. Tibial spurs of posterior legs apparently double. Antennae 

 similar to those of aniericana or nearly.

 and Lomb. 



Male. — The same; antenna! club somewhat more compact, shorter; 

 abdomen rounded caudad.
