CHARLES W. HOOKER. 61 



Rufous, ihorax flavous, head with distinct longish tubercle below the 

 dark fuscous, almost black antennce ; wi?tgs with two horny niaculce ; 

 stigma yellow or fulvous. 



Length, 30 mm. 



Head yellowish, antennae dark fuscous, almost black, with a distinct 

 longish tubercle below the base ; thorax flavous, pleurae and scutellum 

 yellowish, mesonotum marked with dark fulvous, not fuscous ; meta- 

 thorax smooth and impunctate, with a rather indistinct anterior trans- 

 verse carina, behind which it is faintly wrinkled. 



Wings with stigma yellow or fulvous ; discocubital cell with two 

 maculae ; apex of abdomen fuscous. 



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

 give Cameron's description slightly modified. 



Type. — 9. British Museum. 



Cameron remarks that this species considerably resembles 

 E. flavo scutellatus in color, but differs in being smaller, with 

 a distinct longish tubercle below the antennae and no dark 

 fulvous markings on the mesonotum. Comparison of the 

 descriptions shows that it is very closely related to E. spha- 

 celatus Erich., and it is perhaps a synonym of that species. 



Distribution. — San Geronimo, Guatemala.
