marked or with the red bands as in obliqua. Elytra marked as in 

 obliqua, though faintly, or the reddish coloration evenly diffused over the 

 anterior two-thirds. 



External genitalia: As in typical obliqua. 



Internal male genitalia: Very different from that of typical obliqua. 

 Syles very broad just before the very characteristic slender terminal 

 tooth; connective V-shaped; oedagus \\'ith an anterior dorsal process 

 which expands horizontally and a very large and stout terminal process 

 which terminates in two small lateral teeth. 



Distribution: Specimens are at hand from Douglas and 

 Pottawatomie counties. 



Hosts: The writer has taken this species by the hundreds 

 from wild gooseberry in the spring. It is also reported from 

 grape. 



The very characteristic styles, and especially the oedagus, 

 show such great differences from the corresponding organs in 

 typical obliqua, that it is certain that the two forms cannot be- 

 long to the same species. Accordingly this variety is here 

 given specific rank.

Form : Length, 2.5 to 3 mm. Vertex nearly twice as long on middle as 

 next the eye, over one-half wider than long. Pronotum long, scarcely 

 twice as wide as long, anterior margin strongly convex, posterior margin 

 slightly concave. Elytra moderately long. 



Color: Whitish, marked with reddish or brownish. Vertex, pronotum, 

 and scutellum dull reddish, but with distinct white median line and lateral 

 white lines or spots on the vertex and pronotum. El>i:ra whitish, 

 strongly marked with red on clavus and corium, the costal margin in the 

 main white, the apex strongly smoky. 



External genitalia: Practically like obliqua, though the plates of the 

 male seem usually to be more produced and acute apically. 



Internal male genitalia: Styles of about the form characteristic of the 

 tribe, the terminal upturned portion long, posterior terminal tooth long, 

 anterior one very short; connective V-shaped; oedagus widening pos- 

 teriorly into a very broad, three-pointed organ, the lateral points longer
