228 THE UNIVERSITY SCIENCE BULLETIN. 



Color: Ground color like the preceding, variously marked with brown 

 or black. In lightly marked specimens there are faint brown stripes on 

 the elytra and two brownish spots on the margin of the apex between 

 the two usual large black spots. Moderately colored specimens show five 

 dark stripes on the elytra, two on the clavus and three on the corium, 

 with sometimes black triangles in the basal angles of the scutellum. In 

 dark forms the black stripes of the elytra may fuse and make the whole 

 elytron, except the costal margin, almost black. 



External genitalia: As in typical jmnctifrons. 



Internal male genitalia: Styles very characteristic, broadest at point 

 of attachment to connective, then narrowing to middle and again widen- 

 ing, the preapical incision on lateral margin deep and extending cephalo- 

 mesad, forming a distinct shoulder on lateral margin which bears several 

 hairs, the terminal process long, directed caudo-laterad, obliquely trun- 

 cate apically, forming a produced and acute lateral angle, the inner 

 margin with a few preapical small teeth; connective Y-shaped, the arms 

 bending distally around the styles, the stem about as long as the arms, 

 divided and slightly emarginate basally ; oedagus with a large wide dorsal 

 plate-like process at the base which extends dorsad to the membrane from 

 the anal tube, the distal portion wide at base, then narrowing, widening 

 again, and then gradually tapering to the blunt, slightly concavely-tipped 

 apex just before which there are two small sword-shaped, acutely-tipped 

 lateral processes. 



Distribution: Most of our specimens are from Hamilton 

 county. It has also been taken at Kansas City, Mo. 

 Hosts: Willow.

Form: Fairly elongate. Length, 3.75 to 4.25 mm. Vertex about one- 

 half longer on middle than next the eye, nearly or fully twice as wide 

 as long, apex obtusely angled. Pronotum twice as wide as long, lateral 

 margins very short, posterior margin very slightly emarginate. Elytra 

 moderately broad, greatly exceeding abdomen. 



Color: Yellowish or yellowish-green. Vertex with two large black 

 spots near posterior margin and a pair on the anterior margin between 

 the vertex and the front. Scutellum with two large black spots in basal
