The genera of the JPrio?io?nerina have hitherto been supposed 

 to be confined to America; but this genus, and the following, 

 discovered by Mr. "Wallace, rendered it probable that many more 

 species may yet be found in the Malayan archipelago. It is 

 differentiated from the ordinary members of the subfamily in its 

 nearly porrect head, the oblique scrobes, the six -jointed funicle, 

 and the non-approximation of the eyes ; in habit it is like some 

 species of 3£agdalis, Grerm. (The artist has unfortunately drawn 

 the outline of the head in a vertical position.)
