RHTPAROSOMIDAE. 335 



Rostrum and head as long as thorax ; the former indistinctly tricari- 

 nate, with longitudinally rugose sculpture and a well-marked interantennal 

 depression ; the head closely punctate. Thorax widest before the middle, 

 gradually narrowed behind, obliquely impressed near the front, with a 

 rather broad, uninterrupted median channel, its punctation shallow but 

 rather coarse and irregular. Scutellum indistinct, sunken. Elytra slightly 

 wider than thorax at the base, nearly thrice its length, rather distantly and 

 coarsely striate-punctate, with slightly asperate interstices, apices hardly at 

 ■all dehiscent. 



Legs robust, setose ; tibiae minutely denticulate inwardly, the anterior 

 slightly curved externally, their apical structure like that of P. nitidnlus. 



Scape stout, gradually incrassate, attaining the back of the eye ; basal 

 joint of funiculus subnodose at the apex, almost double the length of the 

 obconical 2nd, joints 3-7 moniliform ; club oblong-oval. 



Duller, the thorax especially, than P. nitidalus, the sculpture of the 

 rostrum and thorax manifestly different, the elytra less striate, with coarser 

 and less regular punctures, the structure of the scape and basal joint of 

 funiculus dissimilar, and the pubescence closer and darker, &c. 



c3*. Length (rostrum inclusive), 9| mm. ; breadth, 3 J mm.

 p. 1480. 



Elongate, moderately convex, subopaque ; very scantily clothed with 

 tawny suberect setae, those on the rostrum more flavescent and depressed ; 

 dark fuscous, legs and antennae fusco-rufous. 



Rostrum rather shorter than thorax, a little arched above, rufescent and 

 nearly smooth. Scrobes lateral, broad and deep, beginning near the apex, 

 where they are quite visible above, but not reaching the eyes. Thorax of 

 equal length and breadth, suboviform, slightly wider before the middle than 

 elsewhere, truncate at base and apex, the disc with a few very coarse deep 

 punctures. Elytra oblong, fully twice as long as thorax, slightly wider than 

 it is, and medially emarginate at the base, with obliquely narrowed shoulders, 

 posterior declivity narrowed and vertical ; each elytron is rather coarsely 

 triseriate-punctate, outside these the punctation is less regular ; there is a 

 slight sutural depression at the base, so that the 2nd interstices appear 

 obtusely elevated thei-e, the 3rd from behind the shoulders backwards are 

 subcarinate, sometimes interrupted or obsolete, the declivity is distinctly 

 striate-punctate. 



Legs setose, femora subclavate ; tibiae nearly straight, obsoletely mucro- 

 nate, not serrate inwa dly ; tarsi moderately narrow, with slender out- 

 standing setae underneath, penultimate joint hardly at all expanded but 

 distinctly bilobed. 



Scape thick, with erect setae, inserted near the apex and reaching the 

 thoracic margin ; funiculus with slender grey setae, basal joint quite twice 

 as long as broad and rather longer than the next, joints 3-7 subquadrate ; 

 club abruptly enlarged, subrotundate, triarticulate. 



Underside with some straw-coloured setae, rather coarsely and irregu- 

 larly punctate, but the 3rd and ith ventral segments have only a single 

 transverse series of punctures, and the rufescent 5th is smooth and shining ; 

 the 2nd segment is rather shorter than the 1st and on a slightly lower plane, 

 otherwise the suture would be indistinct ; metasternum nearly smooth *nd
