/O E. p. VAN DUZEE. 



Genital characters. — Male: (PI. I, fig. 23) Valve broad-triaiigiilar, iu length 

 equal to the last ventral segment, apex rounded ; plates ligulate, three times the 

 length of the valve, hardly approximate, their moderately diverging tips obtuse 

 much surpassing the pygofers, their base but feebly gibbous, submargins with a 

 few short white .spines. Female: Last ventral segment (PI. I, fig. 14) of the 

 general form found in the preceding species; long and broad, median notch 

 small, rounded lateral angles moderately produced ; pygofers short and broad, 

 their narrow apex well surpassed by the oviduct. 



Color whitish fulvous, clearer on the head. Head and pronotum quite evenly 

 irrorate with fulvous-brown, becoming fuscous on the disc of the pronotum; 

 scutellum pale, with the arcuated impressed line and apical stride distinct, base 

 closely punctured and obscurely irrorate. Elytra rather closely and evenly in- 

 scribed, disoal areoles of the corium mottled with fuscous, forming about two or 

 three hardly apparent oblique bands, or merely a longitudinal cloud ; front with 

 about four distinct arcs; plates of the male pale, except their outer margins. 



Described from one male and two female examples. Of one pair 

 received from Mr. Uhler the male is labeled " Dacota, Rothauer," 

 and the female " Mouse R." The other female was received from 

 Prof. Osborn, and is without a label. This specimen is slightly larger 

 and paler than Mr. Uhler's material. P. nebulosiis can be readily 

 distinguished from our other large species by the form of the vertex 

 and of the plates of the male, and by the peculiar maculation of the 

 elytra. 



The female example from Mouse River quite strikingly resembles 

 our Aphrophom parallela Say. 



15. Phlepsius spatulatiis d. sp. 



Form rather broad and depressed ; vertex brown, with the base and apex 

 white, including two brown apical spots. Length 7.5 — 9.5 mm. 



Head narrower than the pronotum ; vertex flat, one-fourth longer at the mid- 

 dle than next the eye, apex rounded, anterior edge obtuse; front one-third lon- 

 ger than broad, sides straight from the antennse to the middle of the lorse, where 

 the width is one-third that at the base, suture between the clypeus and front 

 obsolete, or nearly so ; clypeus large, nearly spatulate in form, least width two- 

 thirds that at the truncated apex, outer angles rounded; cheeks broad, outer 

 edges nearly straight below the pronounced median angle, above arcuated, api- 

 cally forming a wide margin beyond the lorse. Pronotum about twice the length 

 of the vertex, nearly flat, wrinkles distinct, hind edge very feebly arcuated. 



Genital characters. — Female : Last ventral segment (PI. I, fig. 15) rather short, 

 ajiical edge more or less produced each side in a large triangular lobe, the in- 

 cluded concavity rounded, with a narrow, acute central notch, either side of 

 which there may be a short acute tooth. Pygofers broad oval, their acute apex 

 a little exceeded by the oviduct. 



Color pale cinereous-testaceous tinged with fulvous on the head, but iu some 

 examples the color is deepened almost to a fulvous-brown. Elytra regularly and 

 finely inscribed; vertex pale or whitish, with a broad, transverse, brown band 

 l)etween the e.yes. This band is irrorate with pale, its anterior edge is straight, 

 posteriorly it sends a branch to the base of the vertex each side of the middle
