27, n. 54 1905. 



Pale fulvous ; head, pleurce and scutellum more or less tinged with 

 flavous ; vertex fuscous or black ; wings hyaline, iridescent, with two 

 ■macules, the larger lanceolate, the smaller linear-oblong, slightly indis- 

 tinct. 



Length, 14-20 mm. ; wing, 12-14 mm. ; spread, 26-29 mm. ; antennae, 

 20-24 mm. 



Pale fulvous, clothed with fine, short pubescence ; head often flav- 

 ous ; antennas uniformly fulvous, frequently light, as long or longer 

 than the body; ocelli large, prominent, well separated, the posterior 

 close to the tops of the eyes ; eyes large, emarginate ; clypeal foveas 

 deep; mandibles bidentate, tipped with black. 



Thorax fulvous, pleuras tinged with flavous ; mesonotum slightly 

 fuscous, scutellum more or less yellow ; metathorax with an anterior, 

 transverse carina, in front of which it is smooth, behind finely areolated. 



Wings hyaline, iridescent, stigma pale fulvous, nervures fulvous to 

 fuscous* ; nervulus antefurcal to interstitial, nervellus broken far below 

 the middle, basal half of the radial vein slightly enlarged, discocubital 

 vein bent; discocubital cell with two maculae, the larger lanceolate, 

 with a more or less distinct appendix, the smaller linear-oblong, often 

 indistinct. 



Legs uniformly pale fulvous, claws pectinate. 



Abdomen shining fulvous ; the two basal segments linear, about 

 equal in length and slightly dilated towards the apex ; the second seg- 

 ment stouter than the first ; the others compressed and gradually en- 

 larged ; the two apical segments sametimes fuscous. 



In redescribing this species I have compared the cotypes 

 with five female and one male specimens. 



Cotypes. — Two 9 's and one cf, No. 76, Cuba, American 

 Entomological Society. 



This species is closely related to E. flavus, but may be 

 readily recognized by the differently shaped maculae and 

 usually smaller size. In the specimens which I have seen 

 these characters seem well fixed. Cameron's specimens 

 represent an altogether different species, as the figure shows, 

 but as I have not seen the types or similar specimens I can 

 only treat them among the unknown. 



' * Specimens which Cameron considered E, mexicanus answer this 

 description aside from their having a second .macula ; this may be a 

 simple variation.
