13. Bembex occidentalis Fox. 



Bembex occidentalis Fox, Proc. Cal. Acad. Sci. (2), IV, p, 10, 9 $ \ Hand- 

 lirsch, 1. c, p. 868, pi. Ill, f. 13; pi. VII. f. 38. 



Lower California ; California, Nevada, Las Cruces, New Mexico 

 (Cockerell). The ventral abdominal segments in this species are 

 broadly banded with yellow. 



14. Bembex TJ-scripta n. sp. Plate XIV , f. 5, 9. 



9 . Black ; head and thorax clothed with a tolerably dense, long, 

 yellowish pubescence ; abdomen with a short, sparse pubescence ; 

 inner and posterior orbits broadly, spot between antenna?, scape and 

 flagellum beneath, elypeus except a large central spot, labrum 

 mandibles except apex, prothorax, meso-and metapleurae and sides 

 of middle-segment entirely, large U-shaped mark and lateral line on 

 dorsulum, line on scutellum and metanotum, curved line on middle- 

 segment, posterior face of the latter toward the sides, all the coxae 

 more or less, femora except a stripe above, tibiae except an internal 

 spot tarsi, two large sinuated spots on dorsal segments 1-4, almost 

 united within, three spots on segment 5, segment 6, and all the ven- 

 tral abdominal segments more or less, the spots on segments 3—5 

 smallest, yellow; wings hyaline, nervures and stigma dark testaceous; 

 eyes diverging a little beneath ; second ventral segment finely and 

 closely punctured throughout ; first transverso-cubital nervure but 

 slightly bent. Length 18 mm. 



£ . — Colored and marked like the 9 except that the front of the 

 head, thorax except above, legs and the first four ventral abdominal 

 segment are almost entirely yellow; scape of antennae short and 

 broad, the flagellum with the joints rather flattened, the sixth to 

 tenth being more or less dentate, the apical joint rather strongly 

 curved; medial femora margined beneath with unusually long teeth 

 or spines; apex of medial tibiae drawn out into a prominence; first 

 joint of medial tarsi strongly curved ; second ventral segment 

 smooth, not dentate or tuberculate; the seventh with two carinae 

 which diverge basally; eighth ventral produced into a spine at apex; 

 stipes of genitalia, as in fig. 5, plate XIV. Length 18-19 mm. 



California ; Tucson, Arizona (coll. Ashmead). Remarkable 

 for its male characters. The shape of the medial first tarsal joint 

 in S is very like that of Monedula formosa, and the markings are 

 very similar to that species.
