Habitat. — While there are no representatives of niveus among the 

 material now being reported upon, it is a well-known fact that the 

 species occurs both in Mexico and some of the Central American 

 countries and several of the West Indian islands. 



63. CEcanthus immaculatus Bruner. 

 CEcanthus immaculatus Bruner, Journ. N. Y. Ent. Soc, XIV (1906), p. 164. 



Habitat. — The present writer has a single female specimen in his 

 collection which was taken on the Island of Trinidad. This species 

 probably also occurs in northern South American countries. It is 

 related to niveus, but lacks the black dots on the underside of the first 

 and second antennal joints. 



There is a female specimen of the genus at hand coming from 

 Corumba (highlands), Brazil, taken in March, also without maculate 

 basal antennal joints. It is shorter-winged, more robust, and has the 

 hind tibiae more strongly serrated than in the type of immaculatus. 

 Its hind femora are also correspondingly shorter and more robust than 

 in that species, while the ovipositor is longer and the cerci shorter. 

 The pronotum likewise is shorter than in immaculatus, as are the hind 

 wings. Its color is much as in niveus, the body and limbs being very 

 pale flavous. Should this insect prove to represent a distinct species 

 it may be called CEcanthus brasiliensis. 



Length of body, 9 , 10.5 mm., of tegmina, 8 mm., of wings, 10.5 

 mm., of hind femora, 7.5 mm. 



The type is deposited in the Carnegie Museum.

(Ecanthus minutus Saussure, Mem. Soc. Geneve, XXV (1878), p. 454; Kirby, Syn. 

 Cat. Orth., II (1906), p. 75. 



Habitat. — There are four specimens, three males and one female, of 

 an QLcanthus at hand, which are placed here. They were taken during 

 the month of April at Chapada, Brazil (H. H. Smith, collector).
