British Species of Homalota. 201 



parts not so dull, the base of the antennge dai-k, the head 

 narrower, and the ventral plate of the seventh abdominal 

 segment differently formed in the female. The antennge 

 are blackish, not thickened outwards after the sixth or 

 seventh joint, formed much as in fungicola, the fourth 

 joint small and transverse. The head is smaller than the 

 thorax, the vertex moderately convex, finely and indis- 

 tinctly punctured. The thorax is not quite so broad as 

 the elytra, nearly half as broad again as long, pretty close- 

 ly and distinctly punctured, the disc not flattened, some- 

 times with a fine indistinct channel. The elytra are of a 

 dark fuscous colour, about one-third longer than the 

 thorax, rather closely and finely punctured. Abdomen 

 with segments two to four pretty distinctly and rather 

 sparingly punctured, fifth segment sparingly punctured, 

 sixth almost impunctate. Thighs pitchy; tibia3 pitchy- 

 testaceous. 



In the male, the upper plate of the seventh abdominal 

 segment has the hind margin truncate, and finely crenu- 

 late, and is terminated on each side by a more distinct 

 but small tubercle, much as in H. fungicola, ; the ventral 

 plate of the seventh segment in the female, has the hind 

 margin fringed with closely-set parallel cilia, and is in 

 the middle distinctly, even rather deeply, excised. 



Rare. I have taken it on one or two occasions at 

 Shirley near Croydon, in the autumn, and also near Edin- 

 burgh. I have seen specimens from Germany. 



Obs. — The cilia at the posterior margin of the seventh 

 segment (ventral plate) of the female, so conspicuous in 

 this species, are also to be found in ? H. fungicola, but 

 are there so short, fine, and light coloured, as only to be 

 perceived with difficulty.

Allied to H. succicola, and perhaps confounded with it ; 

 not quite so shining, rather more depressed, with the
