Phlepsius lobatus Osb., Proc. la. Acad. Sci., v, p. 247, 1898. 

 Phlepsius lobatus Van D., Cat. Heniip. N. A., p. 673, 1917. 



Form: Much like preceding species, but smaller. Length, 5.5 to 5.75 

 mm. Head as wide as pronotum; vertex one-third longer at middle than 

 next the eye, over twice as wide as long, obtusely angled apically. Prono- 

 tum over twice as wide as long, lateral margins short, posterior margin 

 slightly emarginate, transverse wrinkles on basal half indistinct. Eljrtra 

 long, narrowed apically. 



Color: Light brown. Vertex, pronotum, and scutellum dirty-yellow, 

 evenly inscribed with light brown, disc of pronotum sometimes darker. 

 Elytra whitish, evenly irrorate with dark brown except on costal area 

 where irrorations tend to form spots. Face yellowish, quite evenly 

 irrorate with brown. 



External genitalia: Female, last ventral segment very long, strongly 

 narrowed posteriorly, with two distinct lateral lobes, between which the 

 margin is deeply and truncately incised, the median portion slightly 

 produced, carinate, and with a very small incision; pygofers long and 

 narrow, barely exceeded by the ovipositor, spiny on distal half. Male, 

 valve triangular, obtusely angled; plates broad, spined margins tapering 

 slightly sinuately to obtuse apices which greatly exceed the short py- 

 gofers. 



Distribution: Taken in Riley and Pottawatomie counties. 

 Hosts: Unknown.

Form: Rather slender and elongate. Length, 5.5 to 6 mm. Head as 

 wide as pronotum; vertex scarcely longer on middle than next the eye, 

 three times as wide as long, disc convex, obtusely rounded apically. Pro- 

 notum two and one-half times as long as vertex, strongly convex ante- 

 riorly, lateral margins shorter than humeral, posterior margin angularly 

 concave. Elytra long and narrow. 



Color: Vertex, pronotum, and scutellum fulvous. Vertex mottled with 

 brown, often with two darker spots basally. Pronotum often with disc 

 darker than margins which are marked with brown. Scutellum with two 

 dark spots on each lateral margin. Elytra whitish hyaline, heavily in- 

 scribed with brown, with suggestions of two whitish bands starting from 

 the first and the third of the three white spots on the clavus. Face 

 yellowish or fulvous, heavily irrorate with brown. 



External genitalia: Female, last ventral segment half longer than the 

 preceding, narrowed posteriorly, emarginate between the lateral lobes.
