422 AVILLIAM G. DIETZ, M.D. 



base ( $ ), elytral interspaces more narrow, scarcely double the width 

 of the strife, femora mutic, claws simple. Length 2.75 mm. ; 0.11 

 inch. Aside from its smaller size it could not be distinguished from 

 affluentus on superficial comparison. 



Hah. — Canada, Eastern and Western States. 



Var. — Above and beneath clothed with pale, ochreous scales, 

 elytral striae with a row of whitish scales. 



Occurs in ^Maryland, Virginia, Illinois, Kansas and Nebraska. 



C. seriesetosus u. sp. — Elongate, subtrapezoidal. Black, prothoracic lobes 

 and tarsi testaceous, above irregularly clothed with elongate, dirty white scales, 

 intermixed with coarse hair-like bristles, directed forward on the protborax, 

 backward on the elytra, underside more densely clothed with pale yellowish, or 

 white, oval or elongate scales without intermixed hair. Beak very slender, longer 

 than the protborax, subglabrous, very finely punctured, striolate on the sides, 

 antennae slender, inserted about the middle, first and second joints of funicle 

 elongate, latter slender, joints 3-4 a little shorter, outer joints wider, club large, 

 ovoidal. Eyes entirely concealed in repose; head finely and densely punctured, 

 squamous; protborax one-half wider than long, about two-fifths wider at the 

 base than at the apex, strongly constricted behind the apical margin, rounded on 

 the sides, lateral tubercles distinct, acute, dorsal channel deep before and behind, 

 interrupted at the middle; scutel minute, glabrous. Elytra less than one-third 

 wider at the base than the protborax, humeri rounded, somewhat prominent, 

 sides nearly straight, gradually narrowed behind, declivity with acute granules, 

 which become quite prominent on the posterior callus, when viewed from above ; 

 strife and punctures very fine, punctures rather remote, interspaces flat, some- 

 what shining, very finely rugose, each with a row of fine punctures, each bearing 

 a whitish seta, a distinct scutellar spot and other spots irregularly scattered of 

 white or pale yellowish scrobes. Legs slender, femora and tibiae more or less 

 scaly or coarsely pubescent; femora with a small, acute tooth, nearly obsolete on 

 the anterior pair; tibiae parallel, not widened at the tip, latter testaceous, third 

 tarsal joint very broadly bilobed, fourth a little longer than the former, claws 

 armed with a large tooth, inclined towards its fellow. Length 3.0 mm. ; 0.12 inch. 



% . Last ventral segment imjjressed. apical spurs distinct, though small. 



Hab. — Nantucket Island, Massachusetts. 



Three specimens collected by Mr. A. Bolter are before me. A 

 very distinct species, readily distinguished from the preceding by the 

 rows of elytral sette and from the next by the strongly tootlied claws. 



Since the above was written I have received from Mr. F. A. Sir- 

 rine four specimens of this species, three of which were bred from 

 the seed-stalks of kale at Cutchogue (L. I.), N. Y. They are a 

 little smaller in size than Mr. Butler's specimens, the femoral teeth 

 very small, obsolete on the anterior pair. 



C. is^olatllS n. sp. — Oblong, black, antenna- jiiceous, legs rufo-])iceous, above 

 thinly clothed with white ])iliform scales, intermixed with long coarse pubescence.
