with marginal and terminal bristles, the latter strong; male, valve very 

 short, transverse: plates broad, rounding'ly narrowing to obtuse tip with 

 weak marginal bristles; pygofers rather broad, extending half their length 

 beyond the plates and set with long, stiff bristles. 



Described from twelve females and seven males collected at 

 Ames from July 29tli to August 13th. 



While this species has the general color ot'jucundus it differs 

 from that species very distinctly in the oblique reflexed vein- 

 lets and in having the transverse band on the vertex instead of 

 the two parallel spots. From immistus,fintricatus and f' luteolus, 

 which it resembles in venation, it differs in color and size. 



SCAPHOIDEUS PICTURATUS N. SP. 



Color pattern very similar to savctus. Head more sharply angular, 

 reflexed veins less oblique or indistinct. Length to tips of elytra, female 5 

 mm., male 4 mm. 



Vertex sharply angulate at the tip, as long as width between eyes, and 

 nearly twice as long at middle as next eye. Front very slightly widening 

 next antennge, tapering uniformly to base of clypeus; clypeus with sides 

 parallel, base and apex convex; lora? small, suboval; gense roundingly 

 angulate below the eyes. Pronotum sharply arcuate in front, truncate 

 behind, lateral margin extremely short; scutellum small, the elytra with 

 the post-nodal veinlets irregular, the first either absent or not reflexed, the 

 second strongly reflexed, the middle and inner anteapical cells with dis- 

 tinct or obsolete cross nervures. 



Color: Vertex, anterior part of pronotum, scutellum, face, pectus, 

 venter and margin of abdomen above, yellow or greenish-yellow; two 

 minute points next each eye, two short oblique lines near tip, and a very 

 slender median line on vertex, three or four strongly curved arcs on the 

 front, the margins of the olivaceous areas, an oblique band near the tip, 

 and a submarginal border on the elytra, fuscous. The elytra are fusco-oli- 

 vaceous, interrupted with ivoi'y white as follows; a broad oblique band on 

 the base of corium and clavus pai-alleling the sides of the scutellum, adiscal 

 spot at forking of the first sector, a commisural spot and a broad band 

 across the base of the anteapical cells. The nervures are white on the 

 white portions and also in the fuscous part at apex. 



Genitalia: Pemale, ultimate ventral segment short, slightly notched on 

 the median line; pygofers thickly set towards tip with rather fine bristles: 

 male, valve small, plates long, tapering g'radually to the obtuse tip, exceed- 

 ing the short pygofers. Both plates and pygofers are finely ciliate with 

 pale hairs. 



Described from one female received from Prof. H. Garman, 

 Lexington, Ky., and one male which I collected at Burlington, 

 September 5, 1897. 



While this appears superficially to resemble mnctus, the 

 different venation and the different markings on the vertex as
