Collection. — Ent. Soc. Philad. Two specimens. 



May possibly be the male of P. purpuripennts, but the color is en- 

 tirely different, being more of a greenish hue, the third submarginal 

 cell of the anterior wings is larger and much more narrowed towards 

 the marginal cell, and the legs are rather more strongly spinose. The 

 metathorax is smooth and rounded behind. 



Pompilus fulgidus. n. sp. 



Deep blue, the abdomen brilliant blue and purple ; antennse black ; wings 

 fuscous, the anterior pair with a purple reflection : legs slightly spinose. 



Female. — Deep violet-blue ; antennae black, involute; the pro- and 

 mesothorax and pleura with a faint tinge of green ; metathorax smooth 

 and rounded behind. Wings fuscous, the anterior pair with a rather 

 strongly purple reflection; posterior pair paler; third submarginal cell 

 subtriangular. Legs black, tinged with violet-blue ; the four posterior 

 tibiae and tarsi slightly spinose. Abdomen subsessile, convex, polished, 

 with a brilliant blue and violet reflection ; apex pubescent. Length 5$ 

 lines ; expanse of wings 9 lines. 



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



Easily recognized by the brilliant blue and violet polished abdomen. 



Pompilus orbitalis, n. sp. 



Velvety-black; orbits and a central line down the front, golden ; prothorax 

 with a transverse ferruginous line : wings deep violet-blue; abdomen with the 

 four dorsal segments mostly dull ferruginous: legs spinose. 



Female. — Deep velvety-black ; orbits, sides of clypeus, and a line 

 down the middle of the front, bright golden ; antennae black, involute. 

 Thorax : prothorax with a transverse, bright ferruginous line near the 

 posterior margin, slightly interrupted on the middle, and gradually 

 narrowed on each side ; metathorax uneven, rather abrupt behind, with 

 an obtuse prominence or tubercle on each side. Wings dark fuscous, 

 with a very strong deep violet-blue reflection ; nervures black ; third 

 submarginal cell somewhat semicircular, smaller than the second. Legs 

 velvety-black, robust, beautifully sei-iceous; all the tibiae and tarsi 

 strongly spinose. Abdomen sessile, elongate, convex, shining black ; 

 the first four dorsal segments purplish-ferruginous, stained more or less 

 on the middle and apex with fuscous, so that the ferruginous color 

 forms a large ill-defined spot on each side of the segments ; apical seg- 

 ments pubescent. Length 8 lines ; expanse of wings 12 lines. 



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