third, the Litter conical and slender, joints four to ten equal in length, the 

 former distinctly longer than wide, the latter slightly wider than long, 

 eleventh conoidal and acuminate as long as the two preceding together; 

 labium nearly four times as wide as long, truncate at apex, sides parallel. 

 Prothorax slightly wider than the head; about on. -fourth wider than long; 

 sides nearly parallel aud feebly arcuate, more strongly so anteriorly; base 

 slightly wider thau the apex, broadly and evenly arcuate; the latter broadly 

 and slightly more feebly so; posterior aug'es obtuse and slightly rounded; 

 disk moderately convex, finely, very feebly ami rather sparsely punctate. 

 Scutellum large, triangular, slightly wider than long, granulose. Elytra 

 slightly longer than the prouotum, and at base, slightly wider; sides feebly 

 divergent and nearly straight; together slightly wider than long, truncate at 

 apex; disk depressed, sub-alutaceous, very finely, feebly aud rather closely 

 punctate. Abdomen short and broad, very slightly narrower than the elytra; 

 sides parallel; surface minutely, feebly and very sparsely punctate; bo der 

 very deep, vertical, thin. Legs slender; first joint of the anterior and mid- 

 dle tarsi very short, in the latter much slimier than the second; first joint of 

 the posterior slightly longer thau the s cond. Leugt i 3 mm. 



California (Sau Francisco, 1). 



The ligula is deeply bind, the mentum transversely trun- 

 cate, the third joint of the maxillary palpi being feebly swol- 

 len and longer than the second. The species is described 

 because of its departure from the normal European forms, in 

 that the second antennal joint is distinctly shorter than the 

 third, and the first joint of the posterior tarsi but slightly 

 longer than the second. 



FHYTOSUS curt. 



P. bicolor ii. sp. — Form very slender; sides parallel; anterior puts pale 

 reddish-testaceous; legs and antennas same; abdomen black, apex of the last 

 segment slightly paler; pubescence very tine, rather long, moderately dense, 

 senii-erect; surface rather feebly shining, finely and somewhat feebly aluta- 

 ceous throughout. Head but very slightly dcflexed sub-triangular, slightly 

 longer than wide, broadly truncate at base; angles rather broally roundel; 

 sides evenly arcuate; eyes very small, not prominent, coar ely granulated; 

 front depressed, convex only at the sides, excessively rainutel} 7 and feebly 

 p.mctate; in the middle, oa a line with the posterior limits of the eyes, there is a 

 small slightly elongate fovea; antennas very strongly geniculate, slightly longer 

 than the head and prothorax together, sleuder, very feebly incrassate; basal 

 joint much shorter than the next two together, second and third equal in 

 length, four to ten increasing very slightly in length and more distinctly in 

 width, the former just visibly longer thau wide, the latter distinctly wider
