NEW BRITISH SPECIES, ETC., IN 1870. 31 



15. Placusa denticulata, Sharj), /. c, vol. vi, p. 281 



(described). 



Less depressed than most of its congeners, and remarkable 

 by the characters of its male, in which sex the upper surface 

 of the seventh abdominal segment has two tubercles before 

 the apex, which is armed with two lateral incurved spines, 

 betw^een which are three linear teeth, of which the two outer 

 are bifid. 



It appears to be very rare; and has been found at the 

 overflowing sap of birch-trees at Hampstead, Rannoch, and 

 Strath glass. 



16. Oligota ruficornis, Sharp, /. c, vol. vi, p. 282 



(described). 



Larger and broader than O. pusilUmaf with the thorax 

 more transverse, the elytra longer and broader, and the ab- 

 domen slightly narrowed towards the apex. A little larger 

 than O. atoma7-ia, hut with rufo-testaceous legs and antennae, 

 of which the club is broader. 



Very common in hay-stack refuse near London. 



17. HypocYPTUs APiCALis, Brisout, Gren. Cat. et Mat., 



1863, p. 30; Pandelle, /. c, p. 285 ; E. C. Rye, I c, 

 vol. vi, p. 210. 



Expressly attributed to England by M. Pandelle. This 

 species is stated by Brisout to be very near rufipes, Kr. 

 (which, according to Pandelle would seem to be probably 

 only longicorniis}, but rather larger than that insect, of a 

 blacker colour, with longer antennae, and a lighter-coloured 

 abdomen, which is morestronglv contracted at the extremitv.
