longer than in spatulatus; plates narrowing rapidly behind the middle, the 

 tips upturned, divaricate and scarcely acute; a row of bristles along the 

 outer margin, few in numbers, set in a uniform series and a few minute 

 cilia at the extreme tips; pygofers long, exceeding plates, pointed at tip. 



Described from eleven females and four males, collected at 

 Ames, Iowa, July 4th-llth-29th, and August 3, 1896. 



Except for the more yellow color and the different shape of 

 the vertex this species resembles very closely the spatulatus, 

 but there is a distinct difference in the genitalia, notwithstanding 

 the presence of the spatulate process which is so far known 

 only in these two species. Two males which are otherwise 

 apparently identical with the above have the plates passing the 

 pygofers much more acutely pointed, and the elytra distinctly 

 inf uscated at tip. It seems hardly possible that they can belong 

 with this species, but no females agreeing with them have been 

 seen. Dedicated to Mr. E. D. Ball. 



PHLEPSIUS LOBATUS N. SP. 



Color and shape of truncatus but slightly smaller. The female ultimate 

 ventral segment produced at sides into a distinct obtuse lobe. Length 

 to tip of elytra, female, 5.75 mm.; male, 5.50 mm 



Head as wide as pronotum; vertex about one-third longer on middle 

 than next eye (slightly fuller in male than in female). Front almost as 

 wide between the eyes as length, narrowing rapidly to the apex, the mar- 

 gins from antenna? to apex straight. Clypeus narrowed at the base, trun- 

 cate at apex; lora? large, the frontal angles sharp; geute rounding regu- 

 larly from the sinuation below the eye. Pronotum with the posterior por- 

 tion distinctly concave; scutellum broad, with a sharply impressed line on 

 the disk. 



Color: Above, gray from the finely irrorate and lineated white and 

 fuscous markings. Front dark fuscous in upper part, b )Coming lighter 

 below; pectus, venter and legs whiti-h with fuscous maculations and points. 



Genitalia: Female, ultimate ventral segment very long, depressed 

 laterally and produced into marginal lobes, between which the posterior 

 border is convex, the central portion elevated, becoming carinate and 

 minutely notched at posterior border. Male, valve triangular, plates 

 rather narrow, tapering uniformly from base to sub-acute apex. 



Described from one male and one female collected at Little 

 Rock, Iowa, July 2, 1897, by Mr. E. D. Ball, and one female 

 at Ames, Iowa, September, 18th. 



This might easily be mistaken for truncatus, or even for a 

 small irroratus, but the genitalia are strikingly different.
