76 CEROPALES MACULATA. 



Of the economy of this genus of Pompilidce nothing appears 

 to be known: they have been considered as parasites of the 

 genus Pompilus; but their legs almost destitute of spines, and 

 the absence of cilia on the tarsi, I am inclined to consider indi- 

 cate a peculiar economy. The species are found in all quarters 

 of the globe, some being remarkable for beauty of colouring, and 

 others for having the posterior legs disproportionately long. The 

 females are readily distinguished from those of the genus Pom- 

 pilus by their having the antennae porrect, never convolute.
