at base tliau the protborax, imperceptibly widened to behind the middle, thence 

 broadly rounded to the apex; humeri prominent, scutel distinct, glabrous; striae 

 and punctures distinct, the latter rather remote, interstices flat, suberect setse 

 white, very fine; scales small, rather closely placed, a short line at the base of 

 third, one on the entire fifth interspace and humeral line white, rest of surface 

 tesselated with white and brownish scales. Prosternum broadly sulcate, aute- 

 coxal ridges not well defined. Legs long and slender; tibiae slender, nearly par- 

 allel, posterior widened toward the apex, apical hooks distinct: setulose along 

 apical half of inner margin; tarsi slender, first joint much longer than wide, 

 third broadly bilobed, nearly twice as wide as the preceding, fourth joint about 

 one-half longer than the third; claws connate for less than one-half their 

 length. Length 3.25—4.0 mm. ; 0.13—0.16 inch. Plate vii. figs. 1 and 4. 



Hab. — Texas, Illinois, Mis.souri. 



A very distinct species, closely related to the next only, from 

 which, however, it is sufficiently easy to distinguish. The white 

 scales are more persistent, while the darker scales are readily abraded. 



1*. triangularis n. sp. — Elongate-oval, moderately robust, pitchy black. 

 Beak, antennae and legs bright ferruginous; beneath more densely, above very 

 sparsely clothed with small white scales, which are scarcely noticeable except 

 on the elytra, where they form an irregular, broad, oblique stripe, extending 

 from the humerus toward the suture behind the middle. Beak rather stout, 

 cylindrical, curved, densely punctured, subopaque, suhcarinate, indistinctly 

 striate each side, slightly depressed beyond the insertion of the antennae ; scrobes 

 strongly oblique; antennae inserted two-fifths from apex, slender; first and 

 second joints of funicle elongate, former rather stout ; clava ovoidal, not strongly 

 elongate. Head finely alutaceous, remotely punctulate with a few scattered 

 piliforra scales. Protborax a little wider than long, narrowed anteriorly, rounded 

 on the sides, broadly but rather feebly constricted at the apex ; surface densely 

 punctured, punctures round or slightly oval, superficial, those of the disc bear- 

 ing a small, white filiform scale, those on the sides and base larger, oval scales; 

 a feeble indication of a smooth dorsal line. Elytra one-third wider at base than 

 the protborax, nearly subtriangular in general outline, broadly rounded from 

 humerus to apex; striae distinctly and rather remotely punctured ; interstitial 

 setEB obsolete. Legs long and slender, tibiae nearly parallel, posterior slightly 

 incrassate towards the apex, apical armature strongly marked ; tarsi slender, 

 first joint elongate, second scarcely as wide as the former, third very broadly 

 bilobed, and about three times as wide as the second, the fourth less than one- 

 half longer than the third ; claws connate for more than one-half their length. 

 Length 2.75—3.0 mm. ; 0.11—0.12 inch, Plate vii, figs. 7 and la. 



Hah. — Texas. 



Five specimens in Dr. Horn's collection are before me, easily dis- 

 tinguished from lineolatus by the diiierent arrangement of the elytral 

 scales, the bright ferruginous legs, very broadly bilobed third tarsal 

 joint, and the claws connate beyond the middle.
