22 MEMOIRS ON THE COLEOPTERA 



slightly alutaceous, black, with scarcely metallic lustre, the elytra 

 pale brownish-flavate, the suture, fine marginal edge broader at 

 base and two transverse series of long piceous dashes on the alternate 

 intervals, black; under surface and legs piceo-rufous, the latter 

 black distally; head and clypeus rather coarsely, densely punctato- 

 rugose, the sides and occiput sparsely and more finely punctate; 

 front not impressed medially; clypeus flat, rather more than twice 

 as wide as long, broadly rounded and continuously so around the 

 sides, the latter even becoming somewhat convergent at base, the 

 edges all broadly and strongly reflexed; suture with a strong impres- 

 sion near each side; prothorax three-fourths wider than long, the 

 sides feebly converging from the base, feebly arcuate, more rapidly 

 rounded beyond the middle; surface convex, slightly uneven, strongly, 

 not very finely, sparsely punctate, a little more strongly laterad, 

 the entire basal bead strong but not very coarse; elytra not distinctly 

 longer than wide, only feebly inflated, obtuse at apex, the striae 

 feebly impressed and coarsely, closely punctate, much less sulciform 

 than in the preceding, the narrower intervals barely at all more 

 convex, the second coarsely, confusedly punctate, the fourth in 

 single line which becomes obsolete posteriorly; lateral series even, 

 finer and 'less coarsely punctate; pygidium convex, the arcuate 

 punctulation rather sparse and shallow. Male with the inner an- 

 terior claw moderately inflated behind the middle, abruptly bent 

 at base, split in less than apical third, the upper ramus as long as the 

 lower but notably thinner, very finely aciculate. Length (cf) 10.5 

 .mm.; width 5.9 mm. Kansas (McPherson), Knaus. 



stigmatella n. sp. 



Male with the head fully half as wide as the prothorax or wider and with 

 notably developed and convex eyes, narrower in the female and with 

 distinctly smaller and less prominent eyes 5 



5 Color black above, generally with feeble metallic lustre, the elytra 

 pale brownish-flavate, the suture and marginal edge and rarely one 

 or two discal spots, near the middle and arranged transversely, 

 darker; under surface and legs black to piceo-rufous; head notably 

 large, much more than half as wide as the prothorax, the prominent 

 eyes (cf) separated by not quite twice their own width, or ( 9 ) barely 

 by three times, punctato-rugose, sparsely punctate basally; front 

 feebly impressed; clypeus much rounded and with the edges strongly 

 and broadly reflexed, more transverse and less rounded in the female; 

 antennal club a little longer than the stem or equal thereto ( 9 ) ; 

 prothorax four-fifths wider than long, the sides broadly rounded, 

 more so before the middle, feebly converging to subparallel from the 

 base to beyond the middle, convex, not very finely, rather strongly, 

 sparsely punctate, more strongly laterad; elytra slightly elongate, 

 somewhat inflated; striae feebly impressed, the three geminate 

 pairs closely punctate, with the intervals more convex, smooth; 

 second interval coarsely and confusedly, the fourth less coarsely, 

 more uniseriately, and the sixth finely, confusedly and more axially, 

 punctate; punctures laterally almost evenly serial and notably 

 coarse; pygidium black or piceous, the arcuate punctures large,
