Staphijlinidai of the A)nazoii VaUey. 3 1.5 



The head is short, witli the vertex scarcely emarguiate; 

 the vertical line is fine, contiguous at the sides with the 

 eyes, only slightly deflexed, and interrupted in the middle. 

 The thorax is about as broad as the head, bitt a little nar- 

 ro^ver than the elytra, its length considerably less than its 

 width ; the sides only slightly curved, and a little narrowed 

 behind, the hind angles obtuse but not rounded ; its sur- 

 face covered with rather coarse punctures, which become 

 wanting at the front angles, but leave no distinct space 

 along the middle smooth ; the base in front of the middle 

 slightly bi-impressed. Elytra quite one and a half times 

 the length of the thorax, rather closely and coarsely punc- 

 tured, with the punctures much more sparing at the extre- 

 mity. Hind body rather slender, darker in colour than 

 the front parts ; the four basal segments Avith imbricate 

 sculpture. The legs very pale yellow, rather short. 



The female has a rather broad, moderately deep notch 

 in the middle of the extremity of the ventral plate of the 

 7th segment of the hind body. 



Amazons, probably Tapajos ; a single female. 



This species appears rather closely allied to P. robustus, 

 but is very much more slender ; it has the thorax shorter 

 and the elytra less densely punctured, and in the female the 

 lobes at the sides of the notch of the 7th segment are not 

 acuminate. Though the antenna? are broken, they probably 

 much resemble those of P. robustus ; the two basal joints 

 Avhich remain are quite as short, but hardly so stout-^s in 

 P. robustus. 



7. Palaminus discretus, n. sp. Castaneo-testaceus, an- 

 tennis, palpis, pedibusque pallide testaceis ; capite brevi ; 

 prothorace transverse, crebre punctato ; elytris macula 

 suturali fusca. Long. corp. 2^ lin. 



Mas latet. 



Fem. : abdomine segraento 1° ventrali a])ice truncato. 



Antennae pale yellow, short, rather stout for this genus ; 

 3rd joint much thinner and a little longer than 2nd ; 4 — 9 

 similar to one another in thickness, each a little shorter 

 than its predecessor ; 10th distinctly stouter than 9th, but 

 scarcely longer, 1 1th distinctly longer and stouter than 

 10th. The head is short, as broad as the thorax; the 

 vertical line fine, a little deflexed, but scarcely interrupted 

 in the middle, contiguous with the eyes; it is coarsely 

 and closely punctiu-ed. Thorax a little narrower than the
