€6 STAPHYLINID^. 



Not common in England, but Dr. Joy says that he has found it by 

 far the commonest member of the group in flood rubbish from Blair 

 Athol and Dalwhinnie, Scotland. 



G. bishopi, Sharp (Ent. Mo. Mag. xlvi. (2 Ser.xxi.) 1910, p. 131). 

 A narrow black species, with the base of the antennae and the palpi 

 pitchy, and the legs testaceous; head narrow, oblong-ovate, thorax 

 slightly narrowed in front ; elytra longer than the thorax, more fiuely 

 punctured than the rest of the species above mentioned ; tarsi slender. 



This is the most nai^row and elongate species, and in size is a little 

 shorter than G. kei/siantis. The antennae are long with the penultimate 

 joints slightly longer than broad ; the elytra are exceptionally long in 

 pi'oportion to the thorax ; it most closely resembles G. jiennatus, but is 

 ■distinctly larger and darker and has longer antennae ; it is also very 

 like G. velox, but is a little broader, with slightly darker palpi, and has 

 the punctuation of the elytra less impressed. 



The male characters are very distinct : in this sex the last ventral 

 segment of the hind body has a deep excision in great part filled with 

 transparent membrane ; the ajdeagus is long, with the apex hard, 

 rounded, and almost bulbous. L. 5 mm. 



Scotland, very rare : Beattock and Thornhill (Bishop and Sharp) ; 

 Bungay, Suffolk, one specimen from flood rubbish, December I'JIO 

 (Joy) ; Oxford district (Walker). 



ACTOBIUS, Thomson. 

 This genus has been divided by Ganglbauer (Die Kafer von Mittel- 

 europa, ii. 414) into two, Actobins containing A. cinerascens and 

 A. signaticornis, and Neohisnius including A. villosuliis, A. 2)^'Oce7-zchcs, 

 and A. prolixus. He distinguishes the characters as follows : 



Second joint of the antennae thickened, as thick as the 

 first and much thicker than the third. Epimera 

 of the prosternum developed into membranous 

 triangular lobes; metasternum without transverse 

 raised line ........ Actobius. 



Second joint of the antennte not thickened. Epimera 

 of the prosternum wanting; metasternum with a 

 curved raised line Neobisnius. 



In the European catalogue of Heyden, Reitter and Weise, N. jyrolixus 

 is regarded as a variety of N. proceruliis. I am inclined to think that 

 this is the case, although Ganglbauer {I.e. p. 465) apparently regards 

 them as distinct. 



XANTHOLINUS, Serville. 



X. cribripennis, Fauvel, Eaune gallo-rhenane, iii. 3i)0. Closely 



jillied to A', distans, but on the average largei', with a pronounced 



bronze reflection ; the head is more thickly punctured at the sides, and 



the thorax has the anterior angles more strongly rounded, and the
