34 HYMENOPTERA. 



remainder of the pubescence yet stand out more prominently 

 as regular rows ; these regular lines have a tendency to be 

 paired, especially the second and fifth ; discal ciliation or 

 pubescence absent proximad, caudad of the apex of the vena- 

 tion with the exception of a wedge-shaped or acute prolonga- 

 tion proximad to the proximal end of the marginal vein 

 nearer to the caudal margin than to the middle of the wing 

 at that point and a short straight longitudinal row of four 

 cilia farther proximad, just under but not very near to the 

 submarginal vein (about its true center) and separated from 

 the remaining portion of the wing disk by the caudal spur 

 borne by the submarginal vein where it suddenly broadens ; 

 also a similar row of three or four above the submarginal vein 

 farther distad ; discal cilia short, moderately coarse, coarser 

 and longer than the marginal cilia ; a prominent, long proximo- 

 caudal line of about from 10 to 14 cilia, curved, leads from 

 the apex of the stigmal vein ; marginal cilia short, longest 

 along the caudo-apical margin but there not a fifteenth as 

 long as the greatest width of the wing, about as in the males 

 of Lathromeris Foerster ; a few still longer ones proximad of 

 the marginal vein ; absent on the caudal margin proximad of 

 a point opposite to the apex of the stigmal vein. Venation 

 straight not forming a regular arch or bow, submarginal vein 

 slender, straight to its distal third, wider at its base (gradu- 

 ally so) and at its distal third suddenly widening to the width 

 of the marginal vein, at that point also bearing a distinct 

 backward spur, narrower, which points caudad and slightly 

 mesad ; the vein then proceeds to the cephalic wing margin 

 to become the marginal vein which is nearly straight, much 

 shorter than the submarginal vein, no longer than that vein's 

 wide distal fourth and slightly longer than the stigmal vein 

 or subequal to it ; the stigmal vein proceeds disto-caudad, 

 its angle with the marginal vein being greater than that of 

 the marginal and submarginal veins or about 45° ; apex of 

 stigmal vein nearly truncate and very slightly broadened ; 

 near the apex it bears a short, nipple-like spur or uncus point- 

 ing nearly distad or laterad and which nearly forms a fork ; 

 postmarginal vein absent.. Stigmal vein nearly Y-shaped.
