base of clavus, one on the claval suture one-third the distance from the base 

 to apex, a spot on each of the two apical veinlets, a large spot on the disk 

 of corium between the first and second sectors, and another large one on 

 the sutural margin before the median small dot; front gray, with a median 

 white line, and white arcs, the upper pair forming an arch abo7e the rest, 

 nearly transverse; rest of face light, a black spot under each ocellus and 

 one on either side of the antennal base; tergum light yellow, disk clouded 

 with dark, a row of black spots on either margin; connexivum and venter 

 each with a row of spots next the suture; legs maculate. 



Genitalia: Ultimate ventral segment of the female one-half longer on 

 lateral margin than penultimate, posterior margin angularly produced, 

 one-third the length of segment; male valve broad and short; plates broad 

 at base, narrowing rapidly to beyond the middle, with produced attenuate 

 points, one-half longer than width at base, margin stout, fringed with long 

 curved hairs, an oblique black mark on either side at base. 



Described from two females and four males, Ames, Iowa. 



PHLEPSIUS ALTUS N. SP. 

 (Plate xxvi, Pig. 5.) 



Form similar to siqjerbus, short and stout, elytra somewhat 

 flaring: head short and broad, similar to truncatus. Dark ful- 

 vous brown; length, 5.50 mm; width, 2 mm. 



Head slightly wider than the pronotum: vertex scarcely one-third longer 

 at middle than next eye, three times wider than long, less than one-half the 

 length of the pronotum, rounding to the front with a faint carina, as in 

 cinereus; front three times wider above than on clypeus, twice longer than 

 wide, slightly expanded below; lorce large, nearly twice wider than clypeus 

 pronotum two and one-half times wider than long, lateral margins very 

 short, less thao one-half the length of the vertex, posterior angle well 

 marked; elytra broad, about twice longer than wide, without an appendix, 

 veins on clavus but slightly approaching each other in the middle, seldom 

 with a cross nervure central apical cell no longer than breadth on margin. 



Color: Dark fulvous: pronotum and scutellum soiled yellowish-white; 

 i^Torate with fulvous brown, disk of pronotum usually clouded with fus- 

 cous; vertex and face yellow, finely irrorate, almost clouded with fulvous, 

 usually without pattern of marking except the white margined ocelli and 

 a white spot on'the upper angle of the lorae; elytra pearly white, washed 

 with yellowish and irrorate with dark fulvoas, excopt for numerous spots, 

 venter yellowish-brown; legs brown with dark markings. 



Genitalia: Ultimate ventral segment of female longer than penulti- 

 mate; middle half of posterior margin truncate, with a deep median slit 

 and a minute lobate indenture on either side; lateral half of either side 

 produced as a semi-circular lobe against the side of the pygofers: male 

 valve large, longer than ultimate segment, broadly lobate, margin indented 

 on either side of the apex; plate broader than the valve, rapidly, convexly 

 narrowing to the middle, then slightlj' produced, roundingly pointed; ven- 

 tral surface convex, disk apparently raised, lighter. Described from sixty 

 specimens. 



This species has been collected at Ames and Little Rock, 

 Iowa, and specimens are at hand from West Point, Neb.
