NORTH AMKRICAN COLEOPTERA. 283 



71. 1j. all'abilis ii. sji.-Olilong, subt-yliudrical. rufotcstaceous, surface sliin- 

 iu<:. Head moderately I)road, darker in color. Clypeiis feebly but distinctly 

 emargiuate, margin moderately refie.\ed, punctures moderately coarse not close, 

 front more finely and closely punctate. Thorax short, sides regularly arcuate, 

 margin entire, not ciliate, punctuation moderately coarse, regularly placed, not 

 close, smoother near the sides. Elytra with punctures as coarse and close as on 

 the thorax, the surface somewhat scabrous also, the cost.? faintly indicated. Py- 

 gidium coarsely sparsely punctate. Metasternum sparsely coarsely punctate, the 

 hair short aud sparse. Abdomen sparsely punctate at the sides, smoother at 

 middle, not hairy. Last joint of palpi fusiform, slightly impressed. Claws 

 feebly curved, the tooth small and very near the base in the male. Length .61 

 inch : 15 mm. 



Male. — Aiitennal club nearly as long as the stem. Abdomen 

 broadly flattened at middle, the last segment with a slight concavity. 



Of this species I have seen but two male specimens exactly alike. 

 It has a great resemblance in form and color to ephilida, but dittisrs 

 widely in more important characters. 



The inner spur of the hind tibia, although free, is nearly as short 

 as in some species of the cerasina group, and without careful exami- 

 nation might be supposed to be connate with the tibia. The last 

 ventral segment is, however, short, as is usual with these species with 

 both hind tibial spurs free in the male. 



Occurs in Kansas. 



72. I., clypeata (intecim \\ Lee.)— Oblong, slightly broader behind, rufotes- 

 taceous, moderately shining. Head coarsely moderately clo.sely punctate, cly- 

 peus entire, concave, the border rather widely reflexed. Thorax arcuately nar- 

 rowed from base to apex, the margin entire witli short ciliae, surface moderately 

 coarsely and closely punctate. Elytra as coarsely punctate aud rather more 

 closely, the discal costse plainly indicated, but not prominent, humeral urabone 

 rather more prominent than usual. Pygidiura sparsely punctate, smooth at apex, 

 the punctures in female more distinct. Metasternum closely punctate, tlie hair 

 rather sparse and not long. Abdomen very sparsely indistinctly jmnctate at the 

 sides, the last two segments more coarsely. Claws feebly curved, the tooth small 

 and intramediau. Last joint of maxillary palpi fusiform, distinctly impressed. 

 Length .65 —.70 inch ; 16.5 — 18 mm. 



Male. — Antennal club longer than the funiculus. Abdomen 

 impressed at middle, the last segment flat, the anterior border slightly 

 thickened, the surface posterioi-ly with small graimlar elevations. 

 Spurs of hind tibiae unecpial, the outer longer and more slender. 



Female. — Antennal club shorter than the funiculus. Pygidium 

 slightly longer and more distinctly punctate. 



Superficially this species resembles afabi/i)<, but the clypeus is 

 entire, and the male ventral characters different.
