before the middle ; the basal nervure and the anal nervure in the hind wings inter- 

 stitial. Legs stout, of medium length ; the tibial and tarsal spines stout ; the long spur 

 of the hind tibiae not reaching the middle of the metatarsus, thin, sharply pointed. 



5. Pompilus eubule. (Tab. XI. figg. 8, head ; 8 <z, wing.) 

 Long. 15 millim. 



Hab. Mexico, Ven tanas in Durango 2000 feet (Forrer), Amula in Guerrero 6000 

 feet (H. H. Smith). 



Identical as regards form, coloration, and sculpture with P. telemon, but easily 

 known from it by the apex of the clypeus being rounded, not transverse ; the thorax 

 covered with long black hairs ; the prothorax at the base broader and without a neck ; 

 the median furrow wider and quite distinct ; the abdomen shorter and broader ; 

 the long spur of the hind tibiae shorter, the basal part dilated and bearing a brush 

 of thick hairs ; the second cubital cellule in proportion longer than the third, and 

 receiving the recurrent nervure very obliquely beyond the middle. 



V 6. Pompilus macronotum. 



Pompilus macronotum, Kohl, Verh. zool.-hot. Ges. Wien, xxxvi. p. 336 x . 

 Hab. Mexico, Cuernavaca (BilimeTc l ). 



P. macronotum may be known from the preceding two species by the eyes not 

 converging above, thus making the distance separating the eyes from the hinder ocelli 

 much greater than these are from each other ; by the front being finely punctured, and 

 by the long spur of the hinder tibiae reaching to the middle of the metatarsus. 



v 7. Pompilus impudicus. 



Niger, argenteo-pilosus ; capite, pronoto mesonotoque antice rufo-hirtis ; alis fumatis, lacteo fasciatis. 

 Long. 12 millim. $ . 



Hab. Panama, Peiia Blanca 8000 to 4000 feet (Champion). 



Head short, convex in front, concave behind, densely covered with a reddish -golden 

 pubescence to near the antennae ; the cheeks, face, and clypeus shining, sparsely covered 

 with a whitish pubescence ; eyes converging beneath ; the ocelli in a small triangle, 

 the hinder ones separated from each other by a less distance than they are from the 

 eyes; clypeus projecting, the sides oblique, the apex transverse. Pronotum quadrate, 

 longer than the mesothorax. Scutellum convex, narrowed towards the apex; its 

 base golden-pubescent. The base of the median segment with a broad dense band 

 of whitish pubescence; the apex sharply oblique. Pleurae pruinose, plumbeous. 

 Abdomen shorter than the thorax, shining ; a broad band of white pubescence on 

 the apex of the first segment ; the apex of the third segment with a broad white band
