rapidly increasing in size caudad; second segment little more 

 than half the length of first, third and fourth subequal ; fifth and 

 sixth subequal; second and fifth tergites broadly depressed on 

 basal third; all tergites very coarsely striate, the striae smooth 

 and straight, and on most segments ending submarginally ; sixth 

 tergite with the strise continuously concentric beyond a cen- 

 tral point and parallel to the broadly rounded hind margin. 

 Hind tibial spurs very short, scarcely extending beyond tip of 

 tibia. 



Stigma of medium size, four times as long as wide, lower 

 margin subangulate at middle where radius is inserted; first 

 abscissa of radius slightly more than half the length of second ; 

 second cubital cell subtrapezoidal, about twice as long as high; 

 both transverse cubitals oblique; recurrent nervure inserted at 

 extreme apex of second cubital cell ; parallel vein inserted above. 

 In the hind wings, the second recurrent joins anterior vein at 

 origin of radius, which is entirely transparent.

This species is named for the late W. H. Ashmead, former- 

 ly custodian of Hymenoptera in the United States National 

 Museum. 



Genus NEORHYSSALUS novum 



Eyes very large, malar space and cheeks relatively small. Ver- 

 tex posterior of ocelli long. Antennae longer than entire body, 

 scape short and swollen, f unicle broad and half as long as scape ; 

 flagellar joints more than twice as long as wide. Maxillary 

 palpi very slender, long, surpassing tegulse, third to sixth joints 

 subequal, terete. 



Scutellum sexfoveate anteriorly. Metanotum entirely with- 

 out lateral prominences, but fully areolated, middle areae reticu- 

 late-carinate ; spiracles small, round. Disk of mesopleura with 

 a broad, crenulated, oblique furrow. 



Radial cell reaching apex of wing. Radius inserted at middle 

 of the large, deep, subtriangular stigma. First abscissa of 

 radius little more than half length of second ; second cubital cell 

 short and somewhat narrowed apically. Recurrent nervure in- 

 serted far from apex of first cubital cell. Submedian cell a 

 little longer than median. Parallel vein inserted at lower fourth. 



Abdomen subsessile, as long as head and thorax together ; three 

 large, long, flat abdominal tergites exposed, the remainder re- 

 tracted and bent beneath; only the first tergite is distinctly 

 medially carinate. Hind tibial spurs short, straight, and pubes-
