and between the middle and the sides are a few othei* 

 ])nnctures ; the two main scries are only very slightly 

 impressed. Elytra about one and a half times as long as 

 the thorax, the basal portion rather closely ])nnctur('d ; 

 tln' punctures become more Sj)aring towards the extremity, 

 and at the apex are quite Avanting. Ilind body with the 

 four basal segments Avith imbricate sculpture. Legs 

 almost white, rather long and slender. 



In the female the 7th segment of the hind body is 

 simple, the hind margin of the dorsal plate being slightly 

 rounded, while that of the yentral plate (which is scarcely 

 longer) is almost truncate, being scarcely visibly emar- 

 ginate in the middle. 



Tapajos ; a single female. Also from the same locality 

 I have another female, which may possibly be a distinct 

 species, the head being a little smaller and the elytra with 

 rather more punctures towards the extremity. 



16. Pulaminus pcllax, n. sp. Niger, anteimis, palpis, 

 pedibusque pallide testaceis ; thorace sat elongato, basin 

 versus angustato, lateribus leviter rotundatis ; elytris 

 parcius punctatis, apice late L'evigatis. Long. corp. 

 21 lin. 



Head rather large, with the surface in front of the 

 vertical line scarcely coriaceous. Thorax with two dorsal 

 series of punctures convergent in front of the base ; between 

 these in front with a few punctures, and with a few other 

 punctures between the middle and the sides ; the main 

 series scarcely impressed, but the portion between them 

 distinctly elevated except in front. The elytra are rather 

 si)aringly ptmcturcd, the punctures becoming more sparing 

 towards the extremity and altogether wanting at the apex. 



In the female the dorsal plate of the 7th segment of the 

 hind body is nearly truncate, being only very slightly 

 rounded in the middle ; at the extremity the ventral plate is 

 scarcely longer than the dorsal one, and, like it, is rounded, 

 though rather more distinctly, at the apex. 



Amazons ; a single female, Avithout special locality. 



Obs. — This species resembles P. parens extremely, and 

 difiers from the des(n"iption above given of that species 

 only in the characters here mentioned.
