NEW BRITISH SPECIES, ETC., IN 1869. 61 



38. HoMALOTA NiTiDiuscuLA, Sharp, M.S. 



^ ? var, nitidula, Kr. ; Wat. Cat. 

 Dr. Sharp (1. c, 130) sug<^ests this name for the Scotch 

 hill specimens hitherto named H. nitidula in our collections, 

 in case they should prove specifically distinct from the insect 

 of that name found in the South of England, usually with 

 Formica fuliyinoi^a. Compared with the latter (which seems 

 true H, nitidula, Kr.), these hill specimens are lighter, not 

 quite so shining, narrower, especially towards the front, with 

 rather thinner antennas, longer and narrower thorax, and 

 rather shorter elytra. This form is common on Grayvel, 

 near Camachgouran, Perthshire. 



39. HoMALOTA oBLONGiuscuLA, Sharp, 1. c, 130 (de- 



scribed). 

 ohlonr/a, Wat. Cat., nee Kr. 

 Dr. Sharp considers Mr. Waterhouse's insect very closely 

 allied to oblonga, Kr., but to differ from it in being smaller, 

 with a shorter thoiax (which is without any broad shallow 

 impression at the base) and less developed and darker- 

 coloured antennae. 



40. HoMALOTA siLVicoLA, Fuss, Berl. Ent. Zeit., xii, 1868, 



353; D. Sharp, 1. c, 132. 

 lii/pnormn, Sharp, Trans. Ent. Soc, 1866, 

 450, 7iee Kies. 

 Dr. Sharp now refers (after an examination of Fuss's 

 type) to H. silvicola the insect he formerly brought forward 

 as H. hypnorum, to which it is closely allied. 



This species occurs in moss near London, as well as in 

 Scotland ; and is suggestive of the xanthoptera group. It 

 is especially conspicuous for the very long terminal joint of 

 its antennae.
