scales along the base white. Beneath, pectus thinly clothed with dirty gray 

 scales; surface densely and coarsely punctate, each puncture bearing a short, 

 stout, seta. Legs moderately stout, rufous, femora infuscate about the middle. 

 Length 4.5 mm. ; .18 inch. 



t> . Last ventral feebly inipre.ssed near the apex. 



A uniqne, badly preserved specimen in my own collection is labeled 

 South Park, Colorado. A very distinct species, easily recognized by 

 its uniform gray pubescence. The rufous color of the sixth elytral 

 interstice may be due to immaturity. 



W. inirabilis n. sp. — Stout, oblong, piceous, variegated above with white 

 and pale, fawn colored scales, pubescence yellowish, having a brassy lustre ; beak 

 stout, wider at base than apex, almost as long as the thorax ; somewhat convex, 

 median carina feeble, lateral ones indistinct; transverse basal impression obso- 

 lete; sparsely clothed with large white scales and coarse, yellow pubescence, 

 directed transversely and internnxed with very short, stout, suberect hairs. 

 Head broadly trapezoidal, wider than the rostrum at base, subconvex, an ob- 

 scurely elevated ridge between the eyes; front flattened, sparsely scaly; occiput 

 clothed with short pubescence. Thorax as long as wide at the base, latter dis- 

 tinctly wider than the apex ; moderately convex ; sides broadly rounded, apex 

 broadly, but not strongly constricted ; surface densely punctate, obliquely im- 

 pressed in front, carina very fine, linear, almost concealed by scales and somewhat 

 abbreviated at either end. Scales large, round, white, covering the sides rather 

 densely, a row each side of the carina and sparsely scattered on the disc, pubes 

 cence long, coarse. Elytra more than one-half wider than thorax at its base, 

 slightly emarginate at base ; humeri prominent, rounded and subanguiate behind, 

 sides parallel for almost three-quarters their length, rather rapidly rounded to 

 apex; strife impressed, punctures large, approximate; interstices wide, flat, 

 alternate ones with a row of rather distant, slightly clavate .setse, shorter on the 

 convexity ; sides and convexity densely squamose, white and light fawn colored : 

 disc, except triangular basal space and first interstice, variegated with white 

 spots; scutellum and humeri covered with cream colored scales, spaces not cov- 

 ered by scales, are clothed with very fine, appressed, scale-like pubescence. Un- 

 derside densely punctate, each puncture bearing a squamiform hair, which, 

 however, become broader and true scales on the thorax ; side pieces of latter and 

 prothorax, densely scaly. Legs rufopiceous. Length 4.5 mm. ; .18 inch. 



Hab. — Illinois. A single specimen of this very pretty species in 

 Mr. Hike's collection is before me. It appears to be a female, and 

 has the last ventral slightly concave. 



M. Tittaticollis Kirby.— Very similar to the preceding species, but a trifle 

 stouter, diflfei's as follows: beak distinctly tricarinate, median carina prominent, 

 entire and ending in a frontal puncture; transverse basal impression distinct ; 

 less coarsely pubescent, not scaly. Thorax transverse, more than one-half wider 

 than long, strongly rounded at the sides, apical constriction strong, but narrower : 

 median and lateral vitta* sharply defined, rest of surface coarsely pubescent, with 

 scattered scales ; median carina entire or nearly so. Elytra less than one half
