. ois. — r. modestus, above described, resembles tliis 

 species, both in the external characters of the male and 

 the structure of the a^deagus, but ditters strikingly in 

 colour ; it is just possible, however, as all other characters 

 seem to agree, that P. modestus is only an immature form i 



of the P. anceps. I 



13. Palnminus sohrinus,\\ sp, Niger, antennis, palpis, 

 pedibusque ])allide llavis; thorace elongato, basin versus 

 angustato, crebre ])unctato ; elytris fortiter punctatis. 

 Long. corp. 2h lin. 



Antenna pale yellow, rather slender, moderately long ; 

 3rd joint distinctly longer than 2nd, 11th a little stouter 

 than' 10th. Palpi pale yellow. Head about as broad as 

 the thorax ; the vertex a good deal emarginate, the vertical 

 line contiguous with the eyes at the sides, strongly deflexed 

 in the middle, and distinctly interrupted by a longitudinal 

 depression; the surface coarsely, distinctly and closely 

 punctured. Thorax quite as long as broad, greatly nar- 

 rowed behind, but not in the least rounded at the sides, 

 the middle ]iart closely punctured; in front of the base 

 a slightly raised longitudinal smooth S])ace in the middle, 

 the lateral margins sparingly punctured. Elytra scarcely 

 one and a half times the length of the thorax, rather coarsely 

 punctured, the ]nmctures not very close, the apical margin 

 quite smooth. Hind body with imbricate sculpture on the 

 four basal segments, and also on the anterior part of the 

 following segment. Legs pale yellow, rather long. 



The structure of the 7th abdominal segment is but little 

 dissimilar in the two sexes, the hind margins being almost 

 simple ; the terminal joint of the maxillary palpi is, how- 

 ever, considerably larger in the male than in the female. 



Tapajos ; two individuals, male and female.

 tris crebre punctatis. Long. corp. 2\ lin. 



Antennas pale yellow ; 3rd joint slender, a good deal 

 longer than 2nd ; joints 4 — G rather short (a good deal 

 shorter than in 1\ sohrinus), the others broken off. Palpi 

 pale yellow. Head slightly broader than the thorax, the 

 vertical line distinct, very close to the eyes at the sides, 

 strongly deflexed in the middle, and interrupted by a longi-
