424 WILLIAM G. DIETZ, M.D. 



piliforni scales, interspaces flattened, rugose, declivity with a few very small, but 

 acute granules; femora subclavate, each with a large triangular tooth: tihiee 

 stout, widened from base to apex, latter rounded, tarsi rather stout, third joint 

 not broadly bilobed, fourth short, claws with a short, acute basal tooth. Length 

 2.8 mm.; 0.11 inch. 



Hab. — Nevada, Kansas (LeConte). 



A single female specimen in Mr. Ulke's collection. Closely re- 

 lated to sericans, from which it is readily distinguished by its very 

 coarsely punctured prothorax. 



C sericans Lee. — Oblong, depressed, pitchy black, above densely clothed 

 with very small, brown scales with a faint i)early lustre and inconspicuously mot- 

 tled with pale scales, underside densely clothed with dirty white scales. Beak 

 about as long as the prothorax, curved, not very slender, striate and punctured 

 nearly throughout in the male, glabrous in its apical third in the female, anteunie 

 slender, inserted scarcely two-fifths from the apex ( %, and 9)> fi'"st and second 

 joints of funicle of equal length, former more robust, third joint shorter than the 

 second, longer than the following joints, club elongate elliptic. Eyes concealed in 

 repose. Head channeled, coarsely punctured, clothed with elongate scales, whitish 

 on the front and along the channel ; prothorax more than one-half wider than 

 long and two-fifths wider at the base than at the apex, rounded on the sides, nar- 

 rowly constricted at the apex, apical margin elevated, lateral tubercles distinct, 

 obtuse, posterior to these the lateral margin is straight, disc densely and finely 

 punctured, punctures concealed by the scales, channel entire, more deeply im- 

 pressed near the base ; scutel minute. Elytra trapezoidal and little wider at the 

 base than the prothorax, humeri oblique, prominent, sides nearly straight, nar- 

 rowed behind, striae well impressed, closely punctured, interspaces flattened, 

 about twice as wide as the striae, declivity not obviously muricate, a conspicuous 

 line on the base of the sutural interspace of whitish scales, scales on the declivity 

 pale. Legs squamous, femora subclavate, all armed with a large tooth ; tibia' 

 moderately stout, widened towards the apex, tarsi slender, third joint not broadly 

 bilobed, fourth nearly as long as the two preceding joints together, claws armed 

 with a small, basal tooth. Length 2.5-3.0 mm. ; 0.10 0.12 inch. 



% . Last ventral segment with a deep, transversely oval fovea, apical spurs 

 of tibia; distinct, minute. 



Hab. — Iowa, Colorado, Arizona, California (LeConte). 



Two males and four feniales. Dr. Horn's and Mr. Ulke's coll. 



A very pretty species, the purple gloss is not noticeable in .some 

 specimens. Although Dr. LeConte describes the vestiture as " scale- 

 like hairs" and gives the length as 2.0 mm. ; there is no doubt of 

 the identity of this species. 



ang-ulatus group. 

 The species belonging to this group have the antcniial funicle 0- 

 jointed, the femora (at least the posterior j)air) toothed and the claws 

 simple, they all have the elytra ornamented with patterns of con- 

 densed scales. The eyes arc entirely concealed in repo.se by j)romi-
