286 GEO. H. HORN, M. D. 



In this and the next species the anterior femora are provided with 

 slightly spinous but very short hairs on the under side. They belong to 

 Phvrohiits Sharp. 



Occurs abundantly on the Pacific sea-coast. 



C. seminiteiis n. sp. — Form and color of canescen.i ; antennte piceous, short, 

 scarcely passing the hind angles of the head, joints 4-10 wider than long, grad- 

 ually broader externally, the outer joints very transverse; head as in canei- 

 cens, a frontal and vertical median impression, a few large punctures often in a 

 series on each side converging at the occiput, under side alutaceous, more distinctly 

 punctate than t-awewew-s-; thorax as in caMe.wens, very shining; sulci obliterated, 

 and replaced by a few large distantly placed punctures; median line vaguely im- 

 pressed anteriorly; side margin sub-opaque, with a few coarse punctures: elytra 

 as in canewens ; abdomen with punctuation and pubescence as in caneareva ; basal 

 line bisinuous at middle ; beneath with two apical segments very closely punctate, 

 the anterior segments very sparsely punctate ; legs piceous. Length .3fi — .40 inch ; 

 9-10 mm. 



Male. — Last ventral segment triangularly emarginate, and on each side sinuate; 

 anterior tarsi moderately dilated. 



Female. — As in canescens. 



This species closely resembles canescoitt, but is abundantly distinct by 

 the shorter antennae, the thoracic sculpture, the form of the raised ab- 

 dominal line and the ventral punctuation. 



Occurs on the California sea-coast, but is more rare than caneacens. 



C litliocharinus Lee. — Form elongate, depressed, piceous; elytra with 

 side margin and apical spot luteous; legs rufo-testaceous; antennse piceous, barely 

 reaching the middle of the thorax, joints 4-10 nearly square; head large, quad- 

 rate, larger in the male, and larger in area in both sexes than the thorax ; surface 

 opaque, alutaceous, a smooth median space ; sides with coarse rather closely jilaced 

 variolate punctures; beneath less opaque, coarsely punctate; sub-mentum very 

 opaque, black; thorax narrower than tlie head, longer than wide, narrowed pos- 

 teriorly; sides distinctly sinuate; surface opaque, the median space smooth, shin- 

 ing, more convex, not defined by a row of punctures; sides moderately coarsely 

 and closely punctate, the punctures much finer than those on the head; elytra 

 wider and longer than the thorax, longer than wide conjointly, lateral margin and 

 apical spot pale, finely and closely punctate, finely pubescent; abdomen piceous 

 the apical segment sometimes ferruginous, rather finely but not closely punctate, 

 finely pubescent, elevated line at base of segments straight; beneath piceous. the 

 apical segment and the sides often ferruginous, very sparsely finely punctate. 

 Length .24— .36 inch ; 6 -9 mm. 



Male. — Anterior tarsi slightly dilated ; last ventral segment with small trian- 

 gular emargination, the entire apical margin with a pellucW border. 



Female. — Anterior tarsi nearly as broad as in the male ; last vefltral entire, with 

 a narrow pellucid margin. 



The apical pale spot of the elytra varies ; it is sometimes entirely 

 wanting, and rarely extends across the entire apex. The specie!? is 

 readily known by the very coarse punctuation of the head on both the 

 upper and under sides. 



Occurs on the California sea-coast.
