curved laterally, acute apically; aedeagus with dorsal apodeme con- 

 spicuous, expanded laterally and forming two lobes, shaft gradually 

 narrowed, curved anteriorly. 



Color tan; face without obhque brown hnes; thoracic venter not 

 dark; scutellum commonly with orange areas present; fore wings 

 hyahne to subhyaline. 



The holotype of E. guajanae, a female from Eio Piedras, Puerto 

 Rico, and the male holotype of E. calcara, both in the DeLong collec- 

 tion, have been examined. Linnavuori (1959, p. 339) placed guajanae 

 in synonymy under rosea (Scott), but on the basis of material studied, 

 Linnavuori's illustrations and Ribaut's (1952, p. 69) illustrations of 

 rosea (Scott), guajanae is here removed from synonymy. This species 

 is commonly found in Florida, Georgia, and Texas. One specimen 

 from North Carohna has also been examined. Other localities from 

 which material has been examined are Brazil, Mexico, Puerto Rico, 

 Cuba, Jamaica, British Honduras, Panama, and British Guiana. It 

 is commonly collected on sugarcane flowers. 



B. guajanae (DeLong) appears to be closely related to B. hebe 

 (Ku-kaldy) but can be readily distinguished by the unique shape of 

 the aedeagus and by the position of the pygofer process (see key). 

 The apical end of the connective is also more bifid m guajanae.
