AMERICAN COLKOPTKRA. 243 



27. C. defoile Lee. — Reddish brown, nearly three-fifths as wide as long, 

 not evidently narrowed behind and not at all gibbous in profile. Pubescence 

 moderate. Coarser punctures fine and inconspicuous throughout, a little more 

 evident on the elytra. Metasternal punctures fine not or scarcely reaching the 

 sides. Eighth antennal joint nearly or quite as wide as long, quadrately trian- 

 gular. Front tibiae bisulcate; middle tibiae finely sulcate close to the posterior 

 margin. Length 1.6-1.9 mm. 



Hab. — Florida (Enterprise, St. Lucia, Biscayne, Miami, Key 

 Largo, Elliott's Key). Numerous specimens, collections of Hub- 

 hard and Schwarz, and Beyer. 



The apex of the terminal palpal joints is more deeply sinuate or 

 notched than in any other species except punctulatum. 



28. C post it' mil n. sp.— Dark brown, elytra reddish in apical two-fifths. 

 Form just visibly narrowed posteriorly, distinctly though not strongly gibbous 

 in profile. Puhescence fine and sparse; coarser punctures evident but every- 

 where fine and inconspicuous. Metasternum sparsely finely punctate through- 

 out. Eighth antennal joint broadly, subquadrately triangular, a little longer than 

 wide. Front tibia; bisulcate; middle tibiae finely sulcate. Length 1.75 mm.; 

 width 1 mm. 



Hab. — Texas. Three examples taken by Mr. Schwarz at San 

 Diego. 



29. €<• tumidum n. sp. — Dark brown or fuscous, slightly more than half 

 as wide as long, a little narrowed posteriorly and rather strongly gibbous in pro- 

 file. Pubescence fine and short. Coarser punctures rather numerous but fine 

 and inconspicuous on the head, quite strong and close at the sides of the prono- 

 tum, nearly as large but sparser on the elytra. Metasternum sparsely, evenly, 

 finely punctate from side to side. Eighth antennal joint about one-third longer 

 than wide, triangular, with outer angle rounded and terminal edge moderately 

 oblique. Front tibiae bisulcate; sulcus of middle tibiae nearer the middle than 

 the margin. Length 2.5-3.7 mm. 



Hab.— Texas (Fedor, San Diego, Cypress Mills) ; New Mexico. 



One example from Laredo, Texas, in Hubbard and Schwarz 

 collection is doubtfully placed here; the metasternum is more 

 coarsely punctate, and the groove of middle tibia? more nearly mar- 

 ginal. 



30. C. nubilum n. sp.— Reddish brown varying to darker ; elytral suture 

 nearly always paler toward the apex, the elytra especially posteriorly usually 

 feebly vittate, the sides of the pronotum often clouded with fuscous. Form 

 slightly or scarcely narrowed behind, elytra elliptically rounded at apex, sides of 

 prothorax straighter than usual, making the outline nearly hyperbolic in front. 

 the thorax seemingly smaller than common; outline scarcely at all gibbous in 

 profile. Pubescence fine and short. Coarser punctures lacking on the head, 

 very fine and inconspicuous elsewhere. Metasternuni finely punctate, the punc-
