no. 2173. A REVISION OF THE BEMBICINE WASPS— PARKER. 33 



lum approximated medially, fascia on metanotum, small oblique 

 spots on dorsum of median segment, the lateral angles more or less 

 and spot on sides of median segment, all absent on the type specimen, 

 narrow vertical line on anterior border of mesopleurae, fascia on first 

 tergite broad laterally, interrupted and narrowed to a point medially, 

 fasciae on tergites 2-5 narrowly interrupted medially or continuous, 

 with broad, shallow, anterior, medial emargination deepest on tergite 

 2, on which the fascia is the broadest, fascia on tergite 6 broken or 

 complete, lateral spots on ultimate tergite, lateral spots on sternites 

 2 and 3, which ma} r be absent, spot below on anterior and middle 

 coxae, anterior and middle trochanters apically, anterior and middle 

 femora except stripe above, posterior femora distally, tibiae except 

 spot below on anterior pair, and tarsi, greenish yellow or yellowish- 

 white. The apical segment of the flagellum is curved; the middle 

 femora bear below a number of spines; the middle metatarsi are 

 slightly curved on the inner side, which basally bears a row of four 

 rather stout spines and apically a few very short ones. The second 

 sternite is plain and the eighth is without a discal spine. 



Female. — Black: Labrum, mandibles except apices, lower border 

 of clypeus, scape below, space between antennae, spot below anterior 

 ocellus, broad anterior orbits, narrow posterior orbits, line, sometimes 

 broken, on posterior dorsal border of pronotum, tubercles and line 

 leading downward from them, spot on tegulae, lateral spots above them 

 and a pair of small discal spots on scutum, fascia on scutellum inter- 

 rupted medially, short fascia on metanotum, pair of oblique lateral 

 lines on dorsum of median segment, small spot on lateral angles, and 

 another on sides of median segment, fascia on first tergite, interrupted 

 medially and broadly emarginate on anterior middle, fascia on 2-4 

 continuous, all broadly, and that on second deeply emarginate on 

 anterior middle, fascia on fifth narrow and interrupted medially, 

 minute lateral spots on second sternite, anterior femora below, mid- 

 dle and posterior femora distally, tibiae more or less above, greenish 

 yellow or yellowish white. 



In both sexes the flagellum is testaceous below, the wings hyaline, 

 pulvilli indistinct, and pubescence short, sparse, and not conspicuous. 

 The tarsi of the female except the anterior pair, which show some 

 yellow markings, are dusky almost black in some specimens ; the mid- 

 dle and posterior pairs, as in the male, are very slender with all the 

 segments except the ultimate one provided at their distal ends with 

 long straight spines. The tarsal combs on the anterior pair are well 

 developed in the female, but in the male only feebly. The claws 

 are very slender and but slightly curved. 



Length. — 12-14 millimeters. 



Habitat. — Kansas, South Dakota. 



Number of specimens examined — Males, 2; females, 3.
