distinctly longer than in typical comes. Should this prove to be constant, 

 this variety ought to be recognized as a distinct species. At present, 

 however, we do not have enough material at hand to enable us to deter- 

 mine this point. 



Distribution: There are specimens in the Snow collection 

 from Douglas county and from Kansas City, Mo. 

 Hosts: Unknown.

Form: In size and structure like typical comes. 



Color: Yellowish. Vertex with large red spot or unmarked. Prono- 

 tum with red lines on lateral margins and a V-shaped mark on middle or 

 unmarked. Scutellum with two large black basal spots, the anterior por- 

 tion showing through the pronotum. Elytra marked much as in typical 

 comes, though the markings on the corium are usually less distinct. The 

 three black spots of the elytra are usually very distinct. Tip of oviposi- 

 tor black. 



External genitalia: As in typical comes 



Internal male genitalia: These show some fairly distinct differences 

 from those of typical comes yet in many respects they are so alike that it 

 does not now seem wise to give this variety specific rank. The styles 

 seem to be more slender, especially the part just before the broadly ex- 

 panded apex. The oedagus seems to lack the terminal process of the 

 dorsal expansion of the anterior process. 



Distribution: Specimens are at hand from Douglas and 

 Sedgwick counties. It undoubtedly occurs throughout the 

 eastern part of the state. 



Hosts: Our specimens were taken on grape.
