tibial spurs long and acute, especially the innermost one. Abdomen 

 sessile, smooth and somewhat shining, convex above, compressed be- 

 neath, especially so at tip, which is somewhat edged; entirely ferrugi- 

 nous, with a slight pale sericeous reflection. Length 7 lines ; expanse 

 of wings 11 lines. 



Collection. — Dr. J. Gundlach. One specimen. 



Easily recognized by the elongate, narrow form, and the compressed 

 venter and apex of abdomen. 



Pompilus coruscus, Smith. 



Pompilus coruscus, Smith, Brit. Mus. Cat. Hym. iii, p. 156. 

 Collection. — Ent. Soc. Philad. Three specimens. 



One specimen (6£ lines long) agrees with Mr. Smith's description, 

 and has the third submarginal cell petiolated. The other two speci- 

 mens (5 — 5j lines) varies by the prothorax being mostly bright ferru- 

 ginous, the third submarginal cell triangular or nearly so, and the two 

 apical segments of the abdomen entirely fuscous. Should this variety 

 prove to be a distinct species, it may be named insignis. 



Pompilus juxtus, n. sp. 



Black ; three basal segments of abdomen ferruginous ; wings fusco-hyaline ; 

 legs spinose. 



Female. — Black, with an obscure fusco-sericeous reflection; lower 

 part of face and the clypeus with a slight cinereous pile; antennae black, 

 involute. Thorax slightly narrowed about the middle, dull black ; me- 

 tathorax rounded behind. Wings fusco-hyaline, darker at tips, with a 

 faint opaline reflection; third submarginal cell triangular. Legs black; 

 the four posterior tibite and tarsi spinose. Abdomen convex, pointed 

 at tip, the three basal segments ferruginous, except the extreme base 

 of the first and the apical margin of the third, which, as well as the 

 apical segments, are black. Length 4J lines; expanse of wings 7§ 

 lines. 



Collection. — Ent. Soc. Philad. One specimen. 



Closely resembles P. coruscus Smith, and may be a variety of it. 



Pompilus terminatus, n. sp. 



Black; three basal segments of abdomen ferruginous; wings fuscous; legs not 

 spinose, the posterior tibise serrate. 



Female. — Deep black, opaque; mandibles and antennae piceous, the 

 latter long and slightly involute. Thorax narrow; metathorax rounded 

 behind. Wings fuscous, slightly iridescent, the third submarginal cell 

 large, subquadrate. Legs piceous, the posterior tibiae serrate. Abdo-
