Fern. : ahdominc scgmciito 7" vcntrali producto, ajiice

 leviter reeurvis. 



Antenna} rather stout (for tliis genus), almost wliitc, 

 rather short; 3rd joint shghtly longer than 2nd; lOth 

 joint about as long as but distinctly stouter than the 9th, 

 11th a good deal stouter and longer than the lOth, acu- 

 minate at the extremity. Palpi ]>ale yellow, last joint 

 not very large. Head very short, broad, almost as broad 

 as the thorax; the vertical line fine, very slightly deflexed 

 in the middle, contiguous at the sides with the hind margin 

 of the eyes, slightly intcrrui)ted in the middle ; the surface 

 is coarsely and rather closely })unctured. Thorax a good 

 deal broader than long, slightly narrower than the elytra, 

 the base and hind angles rounded; the surface rather 

 coarsely and closely punctured, so that the smooth spaces 

 are almost absent. Elytra not quite one and a half times 

 the length of the thorax, rather closely and only mode- 

 rately coarsely punctured ; the punctures near the scutellura 

 dense, at the extremity distinctly more sparing. Hind 

 body broad, darker in colour than the front parts ; the two 

 apical segments without imbricate punctures. Legs pale 

 yellow, rather stout and short. 



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

 the hind body is produced and has a large dcej) notch in 

 its apical portion ; the sides of this i)late come to a point 

 at their termination, and are a little curved upwards. 



Tapajos ; a single specimen. 



When I first examined it, I sup]iosed this individual to 

 be a male ; but as on dissection I find no trace of the 

 sedeagus, I conclude, with something like certainty, that 

 it is a female.

A rather slender species. The two basal joints of the 

 antennse are pale yellow, as are, no doubt, also the others, 

 though they are broken off in the specimen described. 

 Tlic palpi are pale yellow, with the terminal joint small.
