248 H. C. FALL. 



Hab. — Massachusetts (Blanchard) ; Pennsylvania; Texas (Co- 

 lumbus and Goliad); Missouri; Florida (Tampa, Haulover). 



In a series of specimens taken at Goliad, Texas, by Mr. Schwarz, 

 the color varies from the typical castaneous to piceous and these 

 darker examples show a distinctly dual punctuation of the elytra; 

 other specimens in the same lot are, however, typical in this re 

 spect, and we are thus obliged to regard this as only an individual 

 variation similar to that observed in nigritulum. Dr. Hamilton 

 says of this species : " Next to nigritulum the most common of this 

 genus near Allegheny and Pittsburg. On Vaccinium and other 

 low bushes, June and July, not abundant." 



42. C. politnm u. sp. — Castaneous, inclining to rufous at the elytral apex. 

 Very similar to castaneum, but differing as follows: The form is a little more 

 elongate, less convex when viewed in profile, the elytra slightly narrowed from 

 the humeri in most specimens. Lateral stride of elytra not continued toward 

 the base by shallow grooves, the punctures showing no tendency toward a serial 

 arrangement. Metasternum at side one and one-half times the length of the 

 second ventral segment (nearly or quite as long as the second and third united 

 in castaneum), posterior groove of the front tibise obsolete in apical half. Length 

 1.5-1.9 mm. 



Hab. — Florida (Biscayne, Key West, Punta Gorda, Tampa). 



All specimens seen were collected by either Hubbard or Schwarz. 



This species resembles castaneum closely and has thus far been 

 confused with it. With a little care the two species should be sepa- 

 rated with certainty. 



43. C I ri viale n. sp. — Brown, of varying shade, the elytral apex usually of 

 brighter tint. Form slightly ovate, distinctly though not strongly gibbous in 

 profile; pubescence moderate; coarser punctuation everywhere very fine and 

 indistinct. Metasternum punctate throughout, but very sparsely and finely at 

 sides. Eighth antennal joint triangular, about one-fourth longer than wide. 

 Front tibife rather finely bisulcate ; middle tibise not sulcate. Length 1.4-2 mm. 



Hab.— Texas (Dimmit County; Beeville ; San Diego; Browns- 

 ville; Uvalde; Del Rio ; Big Spring). Arizona (one example col- 

 lected by Morrison) 



The form, small size and nearly invisible coarser punctuation 

 make this species comparatively easy of recognition. 



44. C. conjunctum n. sp.— Dark brown, slightly ovate, and a little gib- 

 bous in profile; pubescence short, cinereous and moderately dense; coarser punc- 

 tuation fine and sparse on the elytra, very fine and indistinct on the prothorax, 

 and practically absent on the head. Metasternum finely sparsely punctured 

 throughout. Front tibise bisulcate ; middle tibiae not sulcate. Length 2.8 mm.
