Genitalia: 9 , ultimate ventral segment long, produced in 

 middle, apex rounded. cT last ventral segment narrow 

 bordered with black, valve, plates and pygofer broken off. 



Described from one 9 and one cT from Ames, Iowa, and 

 two 9 s from Urbana, 111., collected by Mr. F. M. McElfresh, 

 and kindly sent to me by Mr. E. D. Ball. 



This species belongs in the group with melanotus, but is 

 easily separated from that species by the broad gray band 

 and position of the claval vein. 



SCAPHOIDEUS CINEROSUS 11. sp. 



Ashy gray with dark bands or lines on vertex, pronotum 

 and elytra. Resembles obtusus but vertex more acute, and 

 the apical portion of elytra is not fuscous or black. Length, 

 9 , 4-4.50 mm. 



Vertex nearly as long as wide, sub-acute ; front tapering 

 uniformly; clypeus widening but slightly at tip; lorse long, 

 reaching margin of cheek. Pronotum longer than the vertex, 

 hind border barely emarginate. Claval veins hooked, outer 

 bent somewhat toward the suture, but not fusing with it, 

 cross veins from suture to outer claval and between the 

 clavals near the base. 



Color: Light ashy gray; vertex almost white with a light 

 brown crossband between the eyes, and a fine black line, 

 sometimes obsolete, next the anterior margin; face more or 

 less infuscated, the lower part of cheek usually whitish ; cly- 

 peus with a whitish disc. Pronotum light gray with dark 

 patches near lateral hind margin and along anterior border, 

 and two light brown spots near the middle of hinder portion. 

 Elytra ashy gray or whitish, veins infuscated, and faint traces 

 of brownish spots on discal, inner anteapical and apical cells. 



Genitalia: 9 last ventral segment longest at middle, 

 rounded slightly carinate on the middle line toward the apex- 

 pygofers long, slender, with a dark spot near the apex, and 

 scattering white bristles on base and disk, and two brushes of 

 black hairs each side near the apex. 



Described from specimens collected at Ames, Iowa, by 

 Mr. E. D. Ball, and Urbana, 111., (F. M. E.)
