Fasc, p. 27, n. 59, listed 1 1905. 



Pale flavous, vertex yellow, wings hyaline^ stigma pale Jlavous, disco- 

 cubital cell with one subtriangular horny macula. 



Length, 18 mm. 



Body flavous, unicolorous, vertex flavous. Thorax with scutellum 

 more gibbous than in E. concolor, not narrowed behind, scarcely keeled 

 at the sides and not punctate but finely striate at the apex ; metanotum 

 without median keel ; wings hyaline, the third discoidal cellule not so 

 dilated at the apical half as in concolor, discocubital cell with one pear- 

 shaped macula, nervulus interstitial. 



In its unicolorous body this species agrees with E. concolor but is 

 much smaller, and the color more dilute in tint ; E. flavus may be 

 separated from this species by the deeper fulvous tint of the body, by 

 the middle of the vertex being black, and the mesonotum punctate. 



I have not seen a specimen of this species, and can only 

 give Cameron's description rearranged. It is apparently 

 closely related to E. purgatus. 



Type. — British Museum. 



Distribution. — Guatemala (San Geronimo).
