humeral angles round and rather protruding, the sides ampliated 

 a little to near the apex ; the extreme lateral edge is yellowish, 

 and a broadish vitta of a dull red colour extends from the base to 

 near the middle in the centre of each elytron. The under surface 

 and legs are reddish testaceous. 

 Length, 4 lines. 



35. Plochionus sbmivittatus, n.sp. 



Very dark brown, nitid. Head as in P. humeralis, but more 

 lightly impressed in front, the thorax rather more transverse than 

 in that species, with the lateral margins yellow and broad. Elytra 

 scarcely broader than the thorax, finely striate, the interstices 

 flat and extremely minutely punctate, a very narrow lateral 

 border, an elongate oval patch extending from the base near the 

 shoulder to the middle, and an apical patch, yellow. Tlie abdomen 

 and legs pale testaceous. 



Length, 2^ lines. 



I think I am right in associating these two species with the 

 genus Plochiomcs. They are in fact simply Lebise with securiform 

 labial palpi. 



Sub-Family PERICALIDES. 



36. PniLGPHLiEUS Froggatti, n.sp. 



Black, nitid. Head smooth on the occiput, with a somewhat 

 corrugated impression on each side in front, the clypeus trans- 

 verse, the labrum not longer than the width and roundly pointed, 

 the antennae of a I'eddish tinge. Thorax broader than the head, 

 the width near twice the length, very nitid, the apex truncate, 

 the sides widening to the anterior third, where the margin is 

 angled and setigerous, narrowed a little behind to the posterior 

 angles, which are acute and prominent, the base is truncate, the 

 median canal very profound. Elytra broader than the thorax, 

 and little more than twice the length, striate, densely and finely 

 punctate, with a broad dull red vitta in the middle of each elytron, 

 not quite touching the base or apex. 



Length, 2J lines.
