a very fine punctuation and ])ul)escencp, Avlilcli render it 

 quite opaiiue. Thorax dark red, only si iglitly longer than 

 Ijroad, straight at the sides, shining, but at the front angles 

 densely and finely punctured, near the middle sparingly 

 and rather coarsely punctured, along the middle itself a 

 rather broad, but not sharply-limited, space, free from 

 punctures; this space bounded on each side by an irregular 

 longitudinal patch of coarse punctures; the basal ])ortion 

 of the surface free from punctures. Elytra dark reddish, 

 as broad as and only a little longer than the thorax, 

 densely and finely jiunctured, and clothed ^ith a very 

 fine, short, dense, yellowish pubescence. Hind body fus- 

 cous, becoming redder towards the extremity, very densely, 

 finely and evenly punctured, and clothed with an extremely 

 fine and densc-ycllow pubescence. Legs reddish-yellow. 



A single individual, captured l)y ]Mr. liates, and bear- 

 ing no special locality, but probably from Tapajos. 



Obs. — This species is extremely similar to P. opacifi'ons, 

 but has tlie thorax much less densely and regularly punc- 

 tiu'cd, and the pubescence with which the upper surface 

 is clothed is rather denser, finer, and brighter in colour. 



10. riatj/prosopua similis, n. sp. Rufo-fuscus, thorace 

 nitido, pcdibus testaceis ; capite, elytris, abdomineque 

 dense subtilissime punctatis, et griseo-flavescenti pubes- 

 centibus ; thorace ad angulos anteriores dense, subtiliter, 

 disco parcius fortiter punctato ; medio, spatio longitudinali 

 minus discreto, impunctato. Long. corp. 6 lin. 



Thorax just as broad as long ; elytra a little longer 

 than the thorax. 



A pair, $ and ? , of this species were brought from 

 Manaos by Dr. Traill ; they were attracted by light in 

 August, 1874. 



Obs. — This species is so extremely close to P. frontalis 

 that a special description is unnecessary ; it is rather larger 

 and distinctly broader, and its colour is not so bright ; the 

 impunctate area on the middle of the thorax is also not 

 quite so distinct. The diflerent punctuation of its thorax 

 will distinguish it from P. opacifrons, to which species it 

 is also extremely similar. 



Braciiydirus. 



This genus consists at present of five described species, 

 to Avhich I now add nine others. It is quite pccidiar to 

 South America, and was established by Xordmann for a
