Species of Histei'idsi. 427 



is more sparsely punctulate than the prosternum ; the tibiss — 

 anterior and intermediate 5-dentate, posterior setose on the 

 outer edge, with the apices somewhat minutely 3-dentate. 



Hab. Andai, New Guinea. One male example. 



This species is probably very near T. Alhertisii, Gestro ; 

 but it cannot be the same, I think, although the female only 

 of the last is described. 



Trypeticus btfoveolatus, sp. n. 



Cylindricus, subrobustus, niger, nitidus : fronte triangulata, margine 

 cariHato; thorace antice carina brcvi, iu medio posteaque tuber- 

 culato ; pygidio bifoveolato, 



L. 4| mill. 



Cylindrical, somewhat robust, black, shining; forehead 

 triangular and feebly uneven, with a few microscopic punc- 

 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 each side of the head, lateral angles 

 well marked, bisinuous 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 propygidium 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 strige which join 

 in front well behind the anterior edge somewhat in the form 

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

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



Similar to T. Doherti/i, Lew., and T. crassus, Sch., but as 

 regards the abdominal segments it resembles 2\ cmctipygus, 

 Mars., and T. prcedaceus^ Lew.
