Allied to H. Halohrectha, but readily distinguished by- 

 its darker colour, more depressed form, longer elytra, 

 and rather finer but more distinct punctuation, and the 

 different male characters. The antennas are about as 

 long as the head and thorax, thickened towards the apex, 

 pretty distinctly furnished with exsei'ted hairs^ blackish, 

 with the base pitchy ; joints two and three long and 

 slender, three not so long as two ; four to ten each a 

 little broader than its predecessor, from the seventh to 

 the tenth transverse; eleventh joint not quite so long as 

 the two preceding. The head is but little narrower than 

 the thorax, distinctly, deeply, and pretty closely punc- 

 tured, with a fine yellowish- gray pubescence. The thorax 

 is considerably narrower than the elytra, its length nearly 

 equal to its breadth, the sides rounded in front, a little 

 narrowed behind, its punctuation fine and moderately 

 close, not so distinct as that of the head and elytra, with 

 scarcely any impression in front of the scutellum. The 

 elytra are black, nearly one-half longer than the thorax, 

 closely, distinctly, and regularly punctured, and with a 

 fine yellowish distinct pubescence. The abdomen is 

 black and shining, obscurely paler at the apex, segments 

 two to four finely and sparingly punctured, five and six 

 almost impunctate. Legs ]3itchy, or pitchy-yellow. 



In the male, the apex of the dorsal plate of the seventh 

 segment of the abdomen is truncate; the truncate part 

 is narrow, aud not quite straight, for it has an indistinct 

 projection in the middle; the ventral plate of the same 

 segment is considerably narrower at the apex than it is 

 in the female. 



Pretty common under sea-weed on the coasts of Eng- 

 land and Scotland.
