tropical zone of America; at least Dr. Horn, in his recently published excellent revision 
of the Acanthocinini of the United States, does not mention the genus. 
1. Nyssodrys contempta.

Belongs to Myssodrys on account of the considerably elongated ovipositor of the 
female; but the lower lobe of the eyes is as long relatively as in Atrypanius, with the 
difference that it is much narrowed below. A long subtriangular lobe seems to be the 
rule in the typical species of Nyssodrys; but the character has not much systematic 
' importance. 
2. Nyssodrys caudata.

This and the preceding belong to a numerous series of species which I consider as 
forming the typical group of Nyssodrys. They are of elongate, scarcely convex form, 
with gradually and only slightly thickened femora, long first tarsal joint of hind tarsi, 
very broad pro- and mesosterna, and possess in the females long projecting ovipositors. 
Most of the species are confined to the equatorial zone of South America. 
4. Nyssodrys binoculata.

Hab. Nicaraaua, Chontales (Belt).—Soutn America, Amazons}. 
A single specimen, taken by Mr. Belt, closely resembles the type (also unique) from 
the Amazons. 
5. Nyssodrys leucopyga. (Tab. XIII. fig. 18.)

Hab. Nicaraaua, Chontales (Belt ', Janson).
