Hah. Mexico, Yucatan (Gaumer, coll. L. Bruner) ; Guatemala 5 ; Costa Rica (M. A. 

 Carriker, L. Bruner); Panama, Darien (Giglio-Tos, coll. S. H. Scudder). — South 

 America 1-4 , Trinidad; West Indies, Grenada and St. Vincent. 



Specimens of this insect coming from the vicinity of the Isthmus of Panama and 

 from Guatemala are somewhat more robust and have shorter wings than those obtained 

 from the West Indies and the adjoining portions of South America. In this respect 

 they approach the females of the next species. 



2. Vilerna pygmaea, Saussure. (Tab. III. figg. 22, s ; 23, 23 a, $ .)

 Vilerna pygmaa, Bruner, in litt. 



Hab. Mexico ^ Vera Cruz (Bev. Heyde), Cordova (L. Bruner), Orizaba (L. Bruner 

 and H. shorn). 



This species was found to occur in and about the margins of forests, where it could 

 be taken among the fallen leaves and on the trunks of trees near the ground. Saussure's 

 type, which is in the collection of the Geneva Museum, has been examined by the 

 present author. It was obtained at Orizaba.
