Ohs. — P. modestus, above described, resembles this 

 species, both iu tlie external characters of the male and 

 the structure of the a3deagus, but differs strikingly in 

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

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

 of the 1*. anceps. 



13. Palaminns sohritius, n sp. Niger, antennis, palpis, 

 pedibusque palHde flavis ; thorace elongato, basin versus 

 angustato, crebre ])unctato ; elytris Ibrtiter punctatis. 

 Long. Corp. 2h lin. 



Antenni\! pale yellow, rather slender, moderately long; 

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

 than 10th. Pal])i pale yellow. Head about as broad as 

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

 line contiguovis 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 (piite as long as broad, greatly nar- 

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

 the middle part closely ]uinctured; in front of the base 

 a slightly raised longitudinal smooth space in the middle, 

 the lateral margins sparingly punctured. Elytra scarcely 

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

 punctured, the ])tmctures not very close, the apical margin 

 quite smooth. Hind body Avith 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 

 sim])le ; 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. 



14. Palnminus jnincticcps, n. sp. Niger, antennis,

 basin versus angustato, crebre irregulariter punctato ; ely- 

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



Antenna3 pale yellow ; 3rd joint slender, a good deal 

 longer than 2nd ; joints 4 — 6 rather short (a good deal 

 shorter than in P. sob r inns), 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 deilexed in the middle, and interrupted by a longi-
