markings more or less interruptcnl; pronotvim with simple longi- 

 tudinal vittae on sides and a Y-sliapetl vitta on disk, also often 

 broken up into spots; scutellum with l;)asal triangles outlined, and 

 apex touched with color, clavus with three irregular spots, the 

 upper two of which often are united; corium with an ol)li(i[ue 

 streak near base, costal plaque margined on front and inner side 

 by a color streak, which sends a branch toward middle of clavus, 

 and is extended posteriorly, joining a ramose marking on cross- 

 veins at juncture of third and fourth veins, this entire vitta often 

 more or less interrupted. There is an oblique dark streak across 

 posterior part of costal plaque and dark dots at base of fourth 

 apical, and at apex of second apical cells. 



It is convenient to separate specimens with narrower, often 

 interrupted markings from those with heavier, continuous coloi- 

 vittae. Say's description evidently applies to the former, and 

 Fitch's description of vitifex to the latter. Say refers to the color 

 spots as sanguineous, hence the red phase must be considered 

 typical of the variety comes.
