Female. Length 8 lines. Black ; covered with a fine silvery silky 

 pile, very dense and brilliant on the face, base and apex of the meta- 

 thorax, sides of the prothorax and coxae ; the wings subhyaline, the 

 uervnres dark ferruginous ; the joints of the anterior tarsi remarkably 

 attenuated at the base ; the claws of the tarsi small and unidentate ; 

 the tibia? slightly spinose ; the thorax subelongate, the sides parallel ; 

 the metathorax transversely rugose. Abdomen distinctly petiolated, 

 very smooth and shining, abruptly incurved ; the aculeus elongate. 



Male. About the same size as the female, similarly clothed with 

 silvery pile ; the coxae greatly swollen ; the femora much stouter 

 than in the female, and ferruginous beneath ; the anterior tibiae ferru- 

 ginous within ; the posterior tibiae bent inwardly at their base ; the 

 thorax gradually widening to the apex of the metathorax, which is 

 finely roughened transversely and margined at the truncation. Abdo-

Gen. Mygnimia, Smith. 



This genus of Pompilidce contains all those species which have 

 the first recurrent nervure uniting with the second transverso- 

 cubital nervure, the posterior tibiae strongly serrated, with a 

 double row of short spines. These insects are in fact the repre- 

 sentatives of the Pepsis of South America, and embrace some of 

 the largest and most beautiful species of Pompilidce ; all, with one 

 solitary exception, (a species from Mexico), are inhabitants of the 

 Old World ; Pepsis, on the contrary, is almost exclusively found in 

 the New World : I am only acquainted with four exceptions, three 

 being African, and one from Singapore.
