at West Point, Neb. in June has been sent to me by Professor 

 Brimer. The male was collected by Mr. Ball at Little Rock, 

 Iowa, July 2d. 



While this form is strikingly like twiningi in general charac- 

 ters the very marked difference in color, the absence of black 

 bands on the elytra, and the differently colored face cannot fail 

 to distinguish it, and until intermediate forms are found or it can 

 be proven by life-history details that they intermingle it must 

 stand as distinct. It evidently belongs to the plains fauna and 

 probably feeds upon some of the Compositse. 



^^SCAPHOIDEUS OCHRACEUS N SP. 





 In size and color resembling ^jucundus but in venation like intricatas or 



luteolus. Tawny ochraceous and pallid with most of the elytral nervures 



fuscous. Length to tip of elytra, female "6 mm., male 5 mm 



Vertex as long as width between the eyes, nearly as long as prouotum, 

 the margin angularly rounded; front, narrow; margins slightly concave 

 next the antenn^i^, tapering uniformly to base of clypeus, which it equals in 

 width. Clypeus twice as long as width at base, broadening to the apex, 

 which is distinctly truncate; lorw oval, sub-angulate at tips, twice as long as 

 wide; genae broad, slightly concave below eyes and sub-angulate on margin 

 forming a narrow margin below lora?. 



Elytra with the first two reflexei costal veinlets very oblique, as in 

 immidus, the first originating at or just in front of the transverse veinlet; 

 the second near the middle of the outer anteapical cell; the third at the 

 end of the anteapical cell but not touching the apical veinlet. In one spec- 

 imen aa extra oblique vein occurs between first and second. 



Color; Vertex yellow with abroad ochraceous or ochraceous-ruf us band 

 across the disk, the median portion forming a short curve and reaching 

 the width of the band toward the apex, sometimes almost interrupted; the 

 anterior border with a fuscous line broader, fainter, and broken at the 

 apex; front yellow with two black or fuscous lines running nearly from eye 

 to eye, and three or four short broken arcs becoming obsolete toward the 

 middle; a small fuscous spot on gens below the insertion of the antennae; 

 pronotum with two large spots on the anterior margin near the middle; the 

 posterior half, except narrow median line, two large lateral spots and a 

 slightly fainter median stripe, a wide border to nearly all the nervures and 

 the apex of elytra, ochraceous; a spot at end of inner claval nerve a short 

 line at end of outer claval nerve, an elongate sp t at end of clavus, a spot 

 in inner discal area, interrupted lines on the nervures most conspicuous on 

 the retlexed veinlets and next the costa and a sub-apical border. fuscous; the 

 elytral cells whitish hyaline; below light yellow and pallid; the posterior 

 border ultimate ventral segment female, terminal bristles on pygofers; a 

 series of points and terminal annulus on tibia, tip of first joint and all of 

 second joint of tarsus, deep fuscous or black. 



Genitalia; Female, ultimate ventral segment long, the posterior border 

 straight or very slightly produced at the middle. Pygofers full, polished,
