H. PORRECTUS. 



Augustus, niger, sub-nitidus ; palpis antennis tarsisque rufes- 

 centibus ; capite levi ; prothorace capite haud latiore, fere parallelo 

 lateribus carinatis, in medio profunde canaliculate, nitido trans- 

 verseque tenuissime plicatulo ; elytris fere rectis, sub-deplanatis, pro- 

 thorace latioribus, in singulo sex-costatis, costis, modice elevatis, 

 interstitiis angustis, tenuissime rugosis alternisque pumctis remotis 

 seriatis vage insculptis. 



Long. 13, lat. 4 mm . 



Black with the palpi, antennae and tarsi reddish ; head smooth, 

 shining, bi-impressed longitudinally above the eyes ; prothorax nearly 

 linear, black, shining, very finely plicate transversely, disk a little 

 raised and grooved in the centre, lateral margins acute and raised ; 

 elytra sub-opaque, shoulders sloping, sides nearly straight, very little 

 convex on the upper part, each with six moderately raised costas, in- 

 terstices narrow, finely rugose, outer margins with a series of not very 

 deep punctures, and each alternate interstice with a series of faint, 

 irregular punctures difficult to see ; underside and legs black ; anal 

 margin with two setas. 



Narrower than any other Hystrichopus ; the nearest allied form 

 being H. angusticollis, Bohem. I have not seen any female example 

 of this species and it may perhaps prove not to be quite so linear in 

 shape.
