25. Eu]>eliiiu!>4 quercus n. sp. 



9 . — Lenjitli .18 inch ; ovip. .05. 



This species so exactly resembles EupebnuH mirabilis Walsh, in 

 size and general apjDearance, as to be I'emarkable, and were it not 

 for the exserted ovipositor, might easily be confounded with that 

 species. 



It is at once distinguished from it, however, by the yellow exserted 

 ovipositor, by the pleural pieces being black, and not rufo-i)iceous as 

 in mirabilis, and without the white band at base of abdomen. There 

 is a large brown blotch across wings leaving the base and tip hyaline. 



Described from one specimen taken on an oak in April, 1881.
