1444 COLEOPTERA 



is rather longer than the following one, tenth transversely quadrate, 

 eleventh very small. Thorax slightly and gradually narrowed back- 

 wards, lateral margins distinct ; the basal angles not well denned, 

 the anterior distinct ; the surface moderately closely but not coarsely 

 punctured, the broad shallow dorsal impression is divided behind by 

 a smooth linear space. Elytra rather short, slightly and gradually 

 curvedly narrowed from base to apex, shoulders a little prominent ; 

 the striae are regular, the punctures are not larger than the intervals 

 between them ; the interstices are slightly narrower than the striae, 

 the third are acutely bent inwards at the base, the margin is raised 

 along the middle of the base, so that the very short scutellum seems 

 to be but a portion of it. 



The peculiar appearance of the forehead will readily distinguish 

 this from all the species with small terminal antennal joints. 



Length, 1-| lines ; breadth, f line. 



Ho wick. Unique as yet. 



2505. P. elongellus, n.s. Elongate, shining, the knees, an- 

 tennae, and tarsi pitchy-red, body black. 



Head quadrate, coarsely and moderately closely punctured, 

 frontal impressions large but shallow, the sides scarcely at all raised ; 

 eyes moderately convex but not prominent. 



Antenna stout, eleventh joint as long as the tenth but not as 

 broad as it is. Thorax rather narrow, its front margin sinuate in 

 the middle, anterior angles not prominent ; it is slightly wider near 

 the front than it is at the middle, and it is gradually narrowed 

 behind ; the lateral margins are very thin, and the posterior angles 

 are indistinct, but not rounded ; the surface is somewhat irregularly 

 and not very closely punctured, with shining intervals, the disc is 

 flat but not impressed, along the middle there is a narrow smooth 

 space. Elytra elongate, evidently broader than the thorax at the 

 base, not quite parallel- sided, the humeral angles free but not pro- 

 minent ; they have regular punctate striae, the spaces between the 

 punctures are almost level with the interstices, the striae therefore 

 are not deep, they are deep at the extremity however and the apices 

 are dilated ; the basal margin is not raised, so that the scutellum is 

 distinct. Legs long. 



P. rufescens makes the nearest approach to this species, which 

 may be separated at once by the sinuosity at the middle of the apical 

 margin of the thorax. The lateral margins are ill-defined. The 

 eyes are more finely facetted and less convex. P. impressus may 

 be distinguished by the deep and elongate frontal impressions and 

 the cariniform space along the inner margin of the eye.

Mount Arthur. One, amongst other Coleoptera collected by 

 Messrs. Cheeseman and Urquhart. 



2506. P. longipes, n.s. Elongate, moderately shining, head 

 and thorax piceous, elytra, legs, and antennas pitchy-red. 



This resembles P. elongellus, but the head is larger; the eyes
