Barix.e 501 



Pronotal punctures less coarse but isolated basally and on the propleura, 

 elsewhere tending to longitudinal confluence and coarse rugulosity; 

 descriptions drawn from the female 8 



8 — Body larger than in any other species, stout, oblong-oval, convex, 

 shining and black throughout, the legs black; beak (9) cylindric, 

 evenly and moderately arcuate, sparsely but distinctly sculptured 

 and much longer than the head and prothorax, the antennae just 

 visibly beyond the middle; prothorax one-half wider than long, the 

 converging sides nearly straight, rapidly rounding anteriorly, the 

 strongly tubulate apex half as wide as the base, the smooth line 

 well developed, sharply defined and entire; elytra fully a third 

 longer than wide, elliptic, the sides near the obtusely rounded apex 

 feebly sinuate as in Lininoharis, distinctly wider than the prothorax 

 and two and one-half times as long, the humeral prominences dis- 

 tinct; grooves coarse, deep, punctured along the bottom; intervals 

 about twice as wide as the grooves, the squamules from the large 

 but very shallow punctures not distinct. Length (9) 4.0 mm.; 

 width 1.9 mm. Florida (locality unrecorded). . . .. . .illustris n. sp. 



Body in size and general form almost as in spiniger, deep black, shining, 

 the legs piceo-rufous; setiform squamules not evident above, very 

 minute within the coarse punctures beneath; beak (9 ) moderately 

 stout, cylindric, sparsely sculptured, evenly and distinctly arcuate 

 and much longer than the head and prothorax, the antennae slightly 

 though evidently beyond the middle; prothorax transverse, nearly 

 four-fifths wider than long, the sides feebly converging and just 

 visibly arcuate, broadly rounding from slightly before the middle, 

 the briefly but sharply tubulate apex half as wide as the base; 

 surface strongly rugose, only a small lateral area at base being 

 discretely punctate; smooth median line very narrow and sub- 

 cariniform; elytra a fourth longer than wide, subelliptic, with rather 

 prominent humeri, wider than the prothorax and two and three- 

 fourths times as long; grooves deep, strongly punctate along the 

 bottom; intervals barely twice as wide as the grooves, the setiform 

 squamules indistinct. Length (9) 3.2 mm.; width 1.7 mm. 



Northern Illinois rugicollis n. sp. 



Body smaller and more abbreviated, very convex, black and shining, the 

 legs black; beak (9) thicker and slightly shorter than in the pre- 

 ceding, strongly, closely sculptured, distinctly longer than the head 

 and prothorax and similarly arcuate, the antennae exactly at the 

 middle; prothorax less transverse, two-thirds wider than long, the 

 sides converging and distinctly, subevenly arcuate from base to the 

 briefly tubulate apex, which is more than half as wide as the base; 

 surface and median line nearly as in rugicollis; elytra shorter, a 

 fifth longer than wide, much wider than the prothorax and less 

 than two and one-half times as long; grooves strongly punctured 

 along the bottom and about half as wide as the intervals, the punc- 

 tures of the single series of the latter not quite so coarse but well 

 defined and well separated, bearing very distinct setiform squamules. 

 Length (9 ) 2.7 mm.; width 1.4 mm. Illinois (locality unrecorded).
