ABT. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 127 



BEMBIX ALBATA, new species 



Figures 85, 86 



Type (male). — Black: clypeus; labrum; mandibles, except tips; 

 spot between antennae ; scape, except broad line above ; broad anterior 

 orbits shortened above ; spot on tegula ; short, narrow line on scutnm 

 above tegula; broad, continuous fasciae on termites 1-6, the first with 

 a relatively deep, rounded anterior emargination, remaining fasciae 

 each with a broad, shallow anterior emargination whose border is 

 weakly trisinuate; seventh t«rgite entirely; broad, continuous fasciae 

 on sternites 1-6; seventh entirely; femora apically, more extensive 

 below than above; tibiae, except spot below on first and second pairs; 

 and tarsi ; iialc yellow. 



The fasciae on the tergites are exceedingly pale, almost white; 

 those on the sternites are more yellowish, resembling the yellow of 

 the legs. The intermediate femora are neither serrate nor dentate 

 and the intermediate tibiae and metatarsi are normal. The anterioj- 

 metatarsus is provided with six cilia or spines. The second sternite 

 bears a median, small, thinly compressed, sharply pointed process. 

 On the sixth there is a peculiarly swollen area, somewhat triangular 

 in outline with the apex on the midline near the apical border of the 

 sternite. The segments of the flagellum lack evident spines or exca- 

 vations. Genital stipes as in Figure 85, 



The maculations of the allotype (female) are identical with those 

 of the type, except that (1) on the tubercle there is a yellow spot 

 that is extended downward on the posterior margin of the prothorax, 

 (2) the yellow on the legs is more extensive, there being no black 

 present on the middle tibiae, and (3) the basal border of both the 

 sixth tergite and sixth sternite is black. 



The wings on this species are hyaline. The f rons is broad and the 

 inner eye-margins are parallel. The mandibles are slender and the 

 teeth on the inner margin are so much reduced that the mandibles 

 are approximately edentate. The head, thorax, first three segments 

 of the legs, the popodeum, and the basal part of the first abdominal 

 segment in both sexes are covered with long, dense, hoary pubescence, 

 giving to this species a vestiture much like that possessed by some 

 bees. 



Length, 14-17 mm. Described from five males and three females, 

 each of which bear the label " Liideritz-Bucht, XII, 1903, L. 

 Schultze, S." 



Type. — In the Zoologisches Museum der Universitat, Berlin.
