Tetragonotes carinipennis nov. sp. 



Elongate, usual form, dull j-ellow, head and thorax sutlused 

 with rufous, antennae and tarsi dark rufous, elytra with a well 

 marked carina from the shoulder to apex, becoming obsolete at 

 tip, about ten long stiff upright hairs on each carina. 



Type.- — Cochabamba, Bolivia. (Germ.) Length 5 mm. 



Head with broad clypeus and moderate median carina, jirominent frontal 

 tubercles and equate vertex; antennae long, filiform, lower joints shining, last 

 four or five pubescent, reaching well towards the end of the el^ira; thorax 

 with the usual median depression and a rather well marked side depression 

 in line with the angulation; elytra square shouldered, parallel sided and having 

 on each side two obsolete sub-costae occupying the third and fifth interstices, 

 the punctuation very fine and giving an opaque appearance, all the tibiae are 

 strongly curved as in octdatus Har.; the carina on the eh-tra decorated with 

 its long hairs makes this form easily recognized. 



One example. 



Tetragonotes truncatipennis nov. sp. 



Elongate, testaceous yellow, antennae rufous, darkened to- 

 wards the end, tibiae and tarsi clouded with rufous, the hind 

 tibiae strongly curved, the anterior less so, elytra truncate wdth 

 sharp sutural angles, hind femora obtusely, broadly toothed 

 beneath. 



Type. — Merida, Venezuela. Length 7 mm. 



Clypeus square, broad, with a well marked median and obsolete side carina, 

 frontal tubercles large, smooth, inverted pear shaped, vertex and neck some- 

 what uneven and punctulate; antennae filiform, reaching nearly to middle of 

 elytra, joints seven to twelve shortened, scape relatively long and stout; thorax 

 in the regular form for the genus, shining, sparsely punctulate, depressed 

 transversely behind, broadly and flatly down the middle, a distinct round 

 foveate depression each side of the middle; eljira finely j)imctate striate, 

 obsolete at apex, the interstices finely alutaceous. 



The swollen last joint of the hind tarsi is only moderate and 

 in relation to most of the species is analogous to that of Homo- 

 phoeta as compared to OedionycMs. 



One example. 



Physimerus spinosus nov. sp. 



Olivaceous green, elytra strongly punctate striate, sparsely 

 pubescent and with long erect hairs, body below 3'ellowish, 

 tinged with green, joints seven to eight of antennae black, femora
