200 IIYMEXOPTERA OF AMERICA. [pAUT I. 



Hab. The United States, especially the South. I possess fivers 

 individuals taken in Pennsylvania (Rathvon), Illinois (Walsh), 

 Tennessee (Fuchs), Louisiana (Norton), South Carolina (author). 

 I have taken the red variety in Mexico. 



Observation. — I am not entirely certain whether my Monobia 

 ail vat tea should be fused into this species or whether it is a true 

 Monobia, the label of it being uncertain and the palpi having been 

 found in an imperfect state. The type I cannot examine again.
