120 H. C. FALL. 



Known to me from Colorado, Utah, Nevada, the Middle Sierras 

 of California and Vancouver Island (Taylor). 



Our largest species and differing from all others in the very short 

 almost recumbent elytral setse. The European analogue of this 

 species is quadrisignatas Men, to which indeed californicus is ex- 

 ceedingly closely allied. 



13. I*, strangulatus n. sp. — Oblong, moderately elongate, black, legs and 

 antennae rufous; in one example the humeri and a small subapical spot obscurely 

 rufescent. Eyes moderate, separated by a little less than twice their vertical 

 diameter. Antennas not quite as long as the body, outer joints about two and 

 one-half times as long as wide. Head and prothorax rather coarsely and closely 

 granulate, the latter not tuberculate on the disk, abruptly strongly strangulated 

 posteriorly, the bottom of the constriction smooth and impunctate, the sides over- 

 hanging, especially laterally, where they are nearly in contact. Elytra parallel, 

 strial punctures not stellate, elongate, distinctly oblique toward the base; inter- 

 spaces three times as wide as the striae at the middle of the disk. Vestiture of 

 the upper surface throughout consisting of short, rather fine, luteous, much 

 inclined hairs, those of the elytral interspaces not or but slightly longer than 

 those of the punctures. Metasternum with coarse, closely placed shallow punc- 

 tures; smoother at middle and posteriorly. Length 2.3-3.3 mm. 



Florida (Miami and Key Largo) ; collected by Mr. Beyer. 



A remarkable species, possessing in its deep smooth posterior 

 thoracic channel and oblique elytral punctures, characters which do 

 not appear elsewhere in the genus. The sexual differences are 

 probably small. 



14. P. falli Pic. — Black; head, prothorax, sterna, first ventral segment, 

 appendages, and rarely the base of the elytra, rufous. Vestiture fuscous on the 

 elytra, brown or yellowish brown on the rufous parts of the body, the scutellum 

 thickly clothed with pale hairs. Head closely granulate and sparsely, shortly 

 pilose; eyes not very prominent; distant on the front by about twice their 

 diameter. Antennae scarcely as long as the body, moderately stout, the joints 

 feebly obconical, from two to two and one-half times as long as wide. Prothorax 

 rather sparsely granulate, feebly tuberculate at sides, and sparsely pilose. Ely- 

 tra parallel, nearly twice as wide as the prothorax; interspaces a little wider 

 than the striae; setae of the strial punctures scarcely longer than the width of 

 the interspaces, much inclined ; interstrial setae about twice as long and more 

 erect; recumbent hairs or scales entirely wanting. Metasternum densely punc- 

 tate in front and at sides, the punctures rather coarse and nearly circular. 

 Length 2.3-3 mm. 



District of Columbia, Ohio, Kentucky, Texas. 



The color, vestiture and the punctuation of the metasternum ren- 

 der this species one of the most easily recognized in our fauna. It 

 does not seem to be common.
