56 THE UNIVERSITY SCIENCE BULLETIN. 



Male internal genitalia: Styles composed of two unequal pieces, the 

 larger ventrad of the smaller; connective inverted Y-shaped, with slender 

 rounding arms and stem broadened to connect with oedagus; oedagus with 

 wedge-shaped base, to end of which is fastened U-shaped structure con- 

 sisting of a straight anterior arm and a curved posterior one. A pair of 

 slender pointed stylets arise near base of the U and run caudad along 

 either side of the curved arm of the U. In the side of each pygofer is 

 imbedded a curved chitinous bar, the ends of which on emerging turn 

 dorsad and end in a toothed, triangular, pointed style. At the base of 

 the anal tube lies a well developed horseshoe, the tips of which end in 

 upturned points in the pygofers. 



Distribution: Cherokee, Riley, Douglas and Pottawatomie 

 counties are the only ones in which this species has yet been 

 taken. Presumably it occurs throughout the eastern portion of 

 the State. 



Hosts: The records show that grasses and weeds in woods 

 or shaded places have yielded all our specimens. 



Genus Agallia Curt. 



This is group I of the genus Agallia of Osborn and Ball. It 

 differs from the preceding genus in not having the elevated 

 and irregularly curved posterior margin of the vertex, and 

 from the following genus in that the pronotum is finely granu- 

 lated instead of being coarsely punctured and transversely 

 striated. 



Just two species of this genus occur in Kansas. These may 

 be distinguished by the following key. 



KEY TO SPECIES, 



A. Broader, stouter, male plates tapering regularly to acute tip, last 

 ventral segment of female with posterior margin usually elevated. 



4^-punctata. 



AA. Narrowe)", more slender, male p'ates distinctly constricted near the 

 middle, last ventral segment of female with posterior half distinctly 

 depressed. constricta.

Form: This species is not only larger than the other species of the 

 Agallia group found in the state, but it is also proportionately more ro-
