British Species of Hoinalota. 187 



minus crebre sat fortiter punctatis; abdomine fere laevi- 

 gato. Long. 1§ lin. 



Mas ; elytris prope suturam linea longitudinal! elevata 

 instructis. 



Allied to H. hepatica, but smaller, especially narrower, 

 not so dark in colour, with more slender antennse, and 

 shorter thorax. The antennae are unicolorous, reddish- 

 brown, stout, but little thickened towards the apex, basal 

 joints rather long; joints two and three of about equal 

 length, four and five each about as long as broad, six to 

 ten rather transverse; eleventh joint rather long and 

 pointed, about as long as the two preceding together. 

 Head smaller than the thorax, neither finely nor closely 

 punctured, the punctures shallow and indistinct. Thorax 

 pitchy, nearly as broad as the elytra, half as broad again 

 as long, the sides gently rounded in front, scarcely 

 narrowed behind, rather coarsely, pretty densely, and 

 not very distinctly, punctured. Elytra reddish, rather 

 coarsely but indistinctly and not closely punctured, about 

 a fourth longer than the thorax. Abdomen pitchy, the 

 extremity, as well as the margins of the segments reddish, 

 almost impunctate, and sparingly pubescent. Legs yel- 

 lowish. 



The male has a raised fold on each elytron, beginning 

 close to the suture near the hind margin, and getting 

 broader and more indistinct as it proceeds forwards. 



Very rare ; a few specimens found by Dr. Power and 

 Mr. Brewer, in Tilgate Forest, in the nests of Formica 

 fuliginosa, are all I have seen. 



Group XIV. Large species, with the penulti'mate joints 

 of the antennce not transverse. (Species 82 — 86) . 



The members of this group form a natural cluster, allied 

 in many respects to Group V. JET. xantlioptera and cenei- 

 collis occur in numbers in fungi, and decaying vegetable 

 matter ; H. valida and incognita I have found in heaps of 

 vegetable refuse, while H. suhcenea appears to prefer the 

 neighbourhood of rivers and streams . 



82. Homalota suhcenea. 



Nigra, capite thoraceque subaeneis, antennarum articu- 

 lo prime pedibusque testaceis, elytris sordide branneis ;
