3. Trogophlceus lutifrons, n. sp. Kiifiis, caplte fusco- 

 rufo ; protborace transverso, lateribus subdenticulatis, 

 dorso minus distincte bi-irapresso ; elytris sat fortiter 

 punctatis ; abdomine obsolete punctato, apicem versus 

 nitidulo. Long. corp. 1^ lin. 



Antennjfi reddish, rather long, a good deal thickened 

 towards the extremity ; 3rd joint about as long as, but 

 more slender than 2nd ; 4 — 6 subequal, rather small, 

 bead-like ; 7 and 8 broader than the preceding, rather 

 transverse ; 9 and 10 broader than the preceding, also 

 transverse. Head broad and short, but distinctly nar- 

 rower than the thorax, very dull, more obscure in colour 

 than the other parts ; the eyes large, but with a distinct 

 prominent space at the sides behind them, the antennal 

 tubercles short and strongly elevated, but Avithout any 

 distinct impression on the inner side of each. Thorax 

 very broad and short, twice as broad as long, a good deal 

 narrower than the elytra; the sides distinctly narrowed 

 towards the base, and each with three or four minute 

 setigerous prominences, gi^'ing them the appeai-ance of 

 being denticulated ; the surface reddish, very opaque, very 

 densely and indistinctly punctured, with two indistinct 

 longitudinal impressions on the middle, and outside these 

 scarcely visibly impressed. Elytra broad, much longer 

 than the thorax, rather distinctly and somewhat closely 

 punctured, a little shining. Hind body large, very indis- 

 tinctly punctured, the basal segment nearly dull, the 

 others more shining, so that the 6th is quite shining. 

 Legs clear yellow ; under surface unicolorous red, Avitli the 

 hind body densely and finely punctured and pubescent. 



Ega and Tapajos ; two individuals. 



4. Trogophlceus hilaris, n. sp. Rufus, capite ftisco- 

 rufo ; antennis elongatis, articulis nullis transversis ; pro- 

 tborace transverso, lateribus subdenticulatis, dorso minus 

 distincte bi-impresso, angulis anterioribus minus rotun- 

 datis ; elytris dense minus fortiter punctatis ; abdomine 

 apicem versus nitidulo. Long. corp. 1§ lin. 



Antennae elongate, formed almost as in T. latifrons, 

 but Avith joints 4 — 10 each slightly longer, so that 4—6 

 are less bead-like, and 7 — 10 not transverse. Head very 

 short and broad, with a very minute fovea on the vertex in 

 the middle. Thorax twice as broad as long, the sides 

 slightly rounded towards the front, and distinctly narrowed
