ART. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 85 



in length the segment immediately preceding, is somewhat curved 

 and is roundly and obliquely truncate at the apex. The apical half 

 of the lower border of the middle femur is distinctly dentate. The 

 second and sixth sternites are plain and the seventh bears a distinct 

 median, longitudinal carina, which is bordered basally on either side 

 by a short carina. The seventh tergite is deeply sinuate on either 

 side, forming prominent lateral angles that are bluntly spinose and 

 the short median portion is slightly but plainly emarginato at the 

 apex. The spine of the eighth sternite seen from below shows lateral 

 swellings near its middle part (fig. 211). 



The maculations on the allotype (female) are quite similar in 

 character to those of the type, but their color is yellow instead of 

 white. In addition to the lateral lines, the scutum bears a broken 

 U-shaped discal mark composed of narrow lines. The maculations 

 on the side of the thorax and propodeum are somewhat better de- 

 veloped than on the type. The fasciae on the tergites are all con- 

 tinuous and the second and third inclose black spots. Those on 

 tergites four and five are of similar pattern but whether the black 

 spots are completely inclosed can not be determined, owing to the 

 retracted condition of the segments. The spot on the apex of the 

 terminal tergite is less extensive than on the type. The apical spots 

 on the under side of the segments of the tarsi are not so prominent 

 as on the type, particularly on the hinder pair, and the apical black 

 spot above on the terminal segment of all tarsi, although present, is 

 not so intense as on the type. The flagellum is black. No part of 

 the disk of the second sternite is wholly free from punctures, but 

 those on the central part are coarser and more widely separated 

 than those on the sides or those near the basal and apical median 

 borders. 



Variation in the maculations of the paratypes is not great. One 

 female has the sixth tergite black, the fascia on the first tergite 

 interrupted, and that on the fifth broken into spots. On the male 

 paratype from New Britain the fasciae on tergites 2-5 inclose each 

 a pair of black spots and no doubt this may be true for some of the 

 other specimens but the retraction of the segments conceals the 

 evidence. 



The wings are only slightly infumated, those of the female being 

 almost hyaline. The anterior metatarsus bears five spines. The 

 pubescence is short, gray, and inconspicuous. The second abscissa 

 of both radiella and cubitella is present. This species seems closely 

 related to Handlirsch's species pugillatrix and papua. 



Length 18 mm. Described from four males and five females. Of 

 these, three males and four females (including type and allotype) 

 bear a common label, " Neu-Guinea, Ramu-Expedit." The fourth
