no. 2173. A REVISION OF THE BEMBICINE WASPS— PARKER. 15 



The flagellum, except the basal segments below, is black and 

 although specialized areas are present these do not bear pits as do 

 those found on duplicata. The middle tibia and metatarsus are 

 modified in a fashion almost identical with that of obliqua. The 

 apical half of the ultimate segment of the tarsi is decidedly dusky. 

 The process on the second sternite is short sharp and obliquely 

 directed backward. 



Female. — Black: Clypeus, labrum, mandibles except tips, scape, 

 and basal joints of flagellum below, frons below insertion of antennae, 

 small spot before anterior ocellus, anterior orbits, posterior orbits 

 quite narrow above, posterior of pronotum, tubercles, spot on tegulae, 

 brief lateral line on scutum above base of anterior wings, large lateral 

 spots on scutellum, fascia on metanotum, spot on lateral angles of 

 median segment extended on the side and somewhat on the posterior 

 surface of same, spot on mesopleurae, small spots on metapleurae, 

 fascia of first tergite broken into a pair of very large lateral spots and 

 a pair of elliptical medial spots approximated on median fine, the 

 remaining fasciae slightly undulate laterally, deeply and double 

 emarginate medially, the fasciae on second and third produced for- 

 ward and inward on either side of the emargination, most conspic- 

 uous on second, broad fasciae on sternites 2-5, ultimate segment api- 

 cally both above and below, spot on coxae below, quite small on pos- 

 terior pair, anterior and posterior borders of anterior and middle 

 femora, most evident on anterior pair, and coxae, yellow. 



The intermediate tibiae are dilated as in the case of obliqua and the 

 first segment of the middle tarsus is slightly curved basally; wings 

 very slightly infumated. The pubescence is similar to that of 

 obliqua, to which species this one is very similar, save in the color of 

 the maculations. 



Length. — 16 mm. 



Habitat — California, Nevada. 



Number of specimens — males 3, females 3.
