most entire length of scutellum. Posterior half of scutellum lighter 

 colored than the rest of the quite uniformly colored body. 



External genitalia: Female, last ventral segment about as long as 

 wide, posterior half depressed on either side of a median carinate line, 

 posterior margin obtusely rounded; pygofers wide and slightly exceeded 

 by ovipositor. Male, valve twice as broad as long, margins parallel ; plates 

 long and narrow, constricted near middle, making these organs very 

 characteristic; pygofers large, equalling or exceeding the plates. 



Male internal genitalia: Styles of same type as in 4-punctata only the 

 processes here are much longer; connective T-shaped, not as wide as in 

 4-punctata, and without the bend of the former; oedagus large, horn- 

 shaped, with small dorsal process at base and bifid at tip. 



Distribution: This species, like the preceding, seems to be 

 found only in Eastern Kansas as shown by the following map : 



Hosts: Our specimens were taken when sweeping grasses 

 and weeds, on alfalfa, and at electric lights. It seems to be 

 quite a general feeder occurring on a variety of food plants. 



Genus ACERATAGALLIA Kirk. 



This is the third group of Osborn and Ball. These forms 

 are readily separated from the other members of the Agcdlia 

 group by the coarsely punctured and transversely striated 

 pronotum. There are no round black spots on the pronotum, 

 which is either unicolorous or marked with dark bands. 



The three members of this genus that occur in the State 

 may be separated by the following key: 



KEY TO SPECIES. 



A. Spots on vertex large, usually dark, forms. sanguinolenta. 



AA. Spots on vertex small, lighter forms. 



B. Elytra greatly exceeding tip of abdomen. uhleri. 



BB. Elytra scarcely exceeding tip of abdomen. cinerea.
