AMERICAN HYMENOPTERA. 93 



Eleven % specimens. Closely allied to ci/lindricus, but is easily 

 distinguished by the beautiful silvery reflection of the body, by the 

 diflerent form of the marginal and third subraarginal cells of the ante- 

 rior wino;s and by the abdomen being sensibly narrowed at base and 

 not so cylindrical as in that species. 



IS. Pompilus funereus. 



Anop/ius funereus, St. Farg., Hym, iii, p. 449, %.. 



7/^6.— " Philadelphia." Not identified. 



This species seems to approach vinjinu'iiiiis, but the wings are de- 

 scribed as being uniformly black, with a violaceous reflection. Size 

 not given.

 metathorax with a deeply impressed line down the middle ; legs 

 strongly spinose ; wings hyaline, iridescent, margined with fuscous at 

 tip, the marginal cell shorter than usual and somewhat triangular, the 

 third submarginal cell triangular or subtriangular ; abdomen cylindri- 

 cal, the three basal segments covered above with a dense silvery pile,

JTab. — West Virginia, (Coll. Am. Ent. Soc. and Mr. E. Norton.) 

 Two % specimens. This beautiful species is shaped much like a/- 

 Ihuhicus, but is at once distinguished from it by the purplish tint, by 

 the brilliant silvery pile, by the shorter antenna), by the arcuated pos- 

 terior margin of the prothorax, and by the strongly spinose legs; these 

 last three characters also separate it from virginiensis. 



20. Pompilus calipterus. 



Pompilus calipterus, Say, Bost. Jour. Nat. Hist, i, p. 302. 



"Black, polished, slightly pruinose; antennae and feet honey-yellow; 

 wings hyaline, bifasciate with blackish; Length three-tenths of an 

 inch." 



Jfah. — "Indiana." Not seen. 



Probably belongs to the subgenus Agcnia. 



(From Cuba, Mexico and Panama.)
