Species of HxsteridBd. 427 



is more sparsely punctulate than tlie prosternum ; the tibiae — 

 anterior and intermediate 5-dentate, posterior setose on the 

 outer edge, with the a])ices somewhat minutely 3-dentatc. 



Ilab. Andai, New Guinea. One male example. 



This species is probably very near T. Albertisiiy Gestro ; 

 but it eannot be the same, I think, although the female only 

 of the last is described. 



Tryiietictis bifoveolatus, sp. n. 



C} lindricus, subrolmstus, nigor, nitidus : fronte triangulata, margino 

 cariuato ; thorace antice carina brevi, in medio posteaque tuber- 

 culato ; pygidio bifoveolato. 



L. 4| miU. ■ 



Cylindrical, somewhat robust, black, shining; forehead 

 triangular and feebly uneven, with a few microscopic ])unc- 

 tures, margin carinate, straight at the sides, feebly sinuous at 

 the base, apex of the snout emarginate; the thorax carinate late- 

 rally, slightly oblique on eacli side of the head, lateral angles 

 well marked, bisinuons behind the neck, depressed in front, 

 with a median carina touching the anterior margin and leaving 

 a small interspace, a tubercle behind it, punctuation rather 

 sparse and fine ; the elytra punctured somewhat like the 

 thorax, but more densely ; the last three segments of the 

 abdomen are thickened at the edges and project over the 

 sides ; the propygidiura is narrow and transverse, distinctly 

 punctate, punctures not very close, on each side (well within 

 the margin) is an ill-defined fovea; the pygidium clearly 

 punctured, but the punctures are larger than on the pro- 

 pygidium, and at the base on either side, just within the 

 margin, is a very distinct fovea ; the prosternum is one third 

 longer than broad, truncate behind, slightly widening out 

 before the anterior angles, laterally there is a stria which 

 reaches the base and ceases anteriorly where the prosternum 

 widens ; the mesosternum truncate anteriorly and without a 

 true marginal stria, but there are two lateral strife which join 

 in front well behind the anterior edge somewhat in the form 

 of a gothic arch ; the meso- and the metasternum are sparsely 

 punctured. The anterior tibia have five or six strong teeth. 



Similar to T. Dohertyi^ Lew., and T. crassus, Sell., but as 

 regards the abdominal segments it resembles 2\ cinctipyrjus^ 

 Mars., and T. incedaceus^ Lew.
