G02 Coleopterological Notice?, IV. 



1 Ceil trill opus helvinus n. sp. — Oval, convex, dark piceous in color, 

 the beak, antennae and legs more or less rufescent; vestitnre pale ochreous- 

 yellow, squamiform, the scales dense beneath especially on the met-episterna ; 

 on the pronotum they are fine on the flanks beneath, then coarser and closer 

 in a sublateral vitta, then sparse and fine to the median line where they are 

 again coarser and denser, especially toward base ; on the elytra they are more 

 broadly oval, more whitish and densely, unevenly distributed throughout all 

 the intervals, especially on the rather broader third, fifth and seventh. Head 

 densely punctured and squamose toward apex, the basal portions of the beak 

 also densely squamose but with the scales erect and bristling, the beak slender, 

 evenly, rather strongly arcuate, a little longer than the head and prothorax, 

 deeply, rather coarsely punctured and longitudinally furrowed but shining, 

 the two punctate grooves lying along the sides of the median impunctate line 

 especially evident ; antennae with the basal joint of the funicle rather longer 

 than the next three, the second but slightly longer than the third, the club 

 moderate, robust, abrupt, oval, pointed, as long as the preceding four joints 

 combined, densely pubescent, with the basal joint composing fully one-half 

 of the mass, the annulations strong, the successive rings decreasing rather 

 abruptly in transverse diameter. Prothorax one-third wider than long, the 

 sides very feebly convergent and nearly straight to slightly beyond apical 

 third, then broadly rounded, strongly convergent and feebly sinuate to the 

 apex, which is truncate and not quite one-half as wide as the base, the latter 

 transverse, broadly sinuate toward the median lobe which is very small but 

 abrupt and prominent ; disk densely, not coarsely punctured. Elytra abruptly 

 one-fourth wider than the prothorax, rather more than twice as long as the 

 latter, the outline hemi-elliptical, the humeri very small and scarcely at all 

 prominent ; disk deeply but not coarsely striate, the intervals flat and from 

 two to three times as wide as the grooves. Prosternum with an extremely 

 deep elongate-oval excavation, and with a corneous process before each coxa, 

 the process very thick and erect at base, but then abruptly and angularly 

 bent obliquely forward becoming rapidly finely acuminate, the coxae rather 

 prominent, separated by about one-fourth of their own width. Length 1.9-2.7 

 mm. ; width 0.8-1.2 mm. 



Indiana ; Illinois. 



The description is taken from the male, the female being similar 

 in form and structure of the beak and antennae, but having the pro- 

 sternum simply longitudinally and deeply channeled, the channel 

 squamose and limited at the sides by an obtusely elevated ridge ; 

 the coxae are a little less approximate, being separated by nearly 

 one-half of their own width. The measurements given above are 

 taken from the extremes of a series of over one hundred specimens. 



2 C euti inopiis alteruatus n. sp. — Oblong-oval, rather robust, con- 

 vex, piceous-black ; elytra toward the sides rufescent, the antennae and legs 

 dark rufo-piceous ; vestiture yellowish, consisting of fine, not dense squam-'
