94 E. T. CRESSON. 



the anterior margin of the clypeus is deeply emarginate, the posterior 

 margin of the prothorax is angular, and the wings are deep violaceous- 

 black. This species resembles philaJelphicns very much, but is at once 

 separated from that species by the strong greenish color of the body.

^at.— Cuba, (Coll. Am. Ent. Soc). 



One 9 specimen. Easily recognized by the brilliant blue and violet, 

 polished abdomen. The anterior margin of the clypeus is subarcuate, 

 and the posterior margin of the prothorax is angular. 



23. Pompilus (?) purpuripennis. 



Pompil lis purpiu-ipennis, Cresson, Proc. Ent. Soc. Phil, iv, p. 130, 9- 



ifei.— Cuba, (Coll. Am. Ent. Soc). 



One 9 specimen. This magnificent species is recognized at once 

 by the rough and curious sculpture of the metathorax. The head is 

 much compressed, making the front very flat, and the antennae are in- 

 serted in deep fossulets just above the clypeus, in which respects it ap- 

 proaches the genus Paj-apompi'hts Smith (^=z Micropteri/x St. Farg.) ; 

 the prothorax is longer than in the true Pompilus, and differently 

 shaped, the anterior margin being rounded, and not suddenly depressed 

 and strangulated ; the metathorax, however, is not longer than in the 

 true Pompilm, neither are the wings any shorter, as they reach beyond 

 the tip of the abdomen when closed. 



24. Pompilus regalis. 



Pompilus regalis, Smith, Journal of Entomology, i, p. 396, 9 • 

 "Purple-blue; clypeus, mandibles and antennas black; metathorax 

 truncate, transversely grooved at the verge of the truncation, and with 

 some longitudinal divergent striae at the base; wings ample, dark pur- 

 ple, with brilliant shades of violet; abdomen slightly compressed. 

 Length 10 lines."

 '■'■Male. — Black, slightly sericeous; wings dark purplish; second 

 and third cubital cellules a little narrowed at the radial cellule, particu- 

 larly the latter, which is less than two-thirds the length of the second, 

 in that part; basal series of transverse nervures not dislocated; meta- 

 thorax with a very slight reflection of purplish, and without any im-
