This is an unusually well-marked species. The labrum is abnor- 

 mally long and the maxillae are longer than the labrum, extending 

 backward well beyond the coxae of the anterior legs. In this elonga- 

 tion of the maxillae this species resembles those belonging to the 

 genus Steniolia. The ocelli are not entirely obliterated. At the 

 base the seventh tergite bears prominent lateral angles that are pro- 

 duced into short, blunt spines, and the apical portion of the tergite 

 is strongij' rugose. The first cubital cross vein is almost straight. 

 The sixth sternite bears a broad median process whose posterior 

 end terminates in two blunt prominences with a slight depression 

 between them. 



Fox describes this species from males taken at Magdalena Bay, 

 Lower California, May 30, 1925, by H. H. Keifer. 



BEMBIX BroENTATA Van der Linden 



Bembex bidentata Van der Linden, Nouv. Mem. Acad. Sci. Bruxelles, vol. 5, 

 1829, p. 11. — Handlibsch, Sitz. Akad. Wissensch, Wien, Math. -Nat. 

 CI., vol. 102, 1893, p. 773.— Dalla Torre, Cat. Hym., vol. 8, 1897, p. .^02. 



The male of this species is well marked. The last three segments 

 cf the antenna are excavated below; the anterior metatarsus bears 

 seven spines ; the posterior border of the middle femur is compressed 

 to a thin edge whose apical half is dentate; the second and sixth 

 sternites are without tubercles; and the seventh tergite is without 

 lateral ridges but is provided at the base with prominent lateral 

 spines. The propodeum and the metathorax are black and the 

 mesothorax is almost wholly black. The fascia on the first tergite 

 IS widely interrupted; those on 2-4 are continuous; that on tergite 

 5, continuous or broken into three spots. The sixth bears a single 

 central maculation and the apex of the seventh is maculated.
