AKT. :.'6 WASPS OF SUBFAMILY PSENINAE MALLOCH 53 



and prepectiis are rather deeply but not contiguously punctate, the eps 

 2 more closely so. Lateral areas of the propodenm appearing almost 

 granulose in the male, but under a high-power lens distinctly rugose 

 or reticulate, in the female these areas are closely and rather evenly 

 striate almost up to the curve, at which point they become rugose. 

 Petiole of the abdomen in the male almost as long as the hind femur 

 and longer than the swollen apical part. Legs and wings normal. 



Length, 8-9 mm.

PSENIA RUFIBASIS. new species 



I'late 2, FiGUKi: 32 



Male and female. — This species does not belong to the same group 

 as sujfusa, the intercarinal space on venter of head being much nar- 

 rower and the abdominal petiole shorter. The hairs of the face in 

 the female are brassy yellow, the antennal scape is broadly yellow 

 below in male and at apex in female, and the flagellum is broadly 

 yellow below on even the basal segment. Petiole of abdomen chest- 

 nut-colored, first and second tergites entirely red in female, partly 

 dark on disk in male. Femora and tibiae of all legs fulvous-yellow, 

 bases of hind tibiae and all the tarsi more whitish yellow. Fore 

 wings brownish hyaline, veins and stigma dark brown. 



Feviale. — Front with small separated punctures; clypeus almost 

 rounded at apex; intercarinal space at center about half as wide as 

 basal segment of fore tarsus at apex. Mesonotum broadly longitudi- 

 nally punctato-striate on disk, the scutellum similarly sculptured; 

 enclosure of propodeum as in plate 2, figure 32; mesopleura dull, 

 shagreened, with rather coarse punctures in wrinklelike striae, which 

 are oblique on lower part and closer and almost longitudinal on 

 upper part (eps 2). Petiole about three fourths as long as hind 

 femur and subequal to the apical part of the segment; pygidium 

 about 2.5 as long as its width at center. Legs and wings normal. 



Male. — Differs from the female in having the face white haired, 

 the flagellum not clubbed, flat below and with a linear sensory eleva- 

 tion on basal and apical segments, faint on preapical one. 



Length, 8-8.5 mm.
