ELATERID^. 141 



APHAIXTASTICUS, Latreille. 



A. emarginatus. Fab. (Syst. El. ii. 213, 151). Longer and 

 more cj-lindrical than A. 2)'i('Sillus, 01., from which insect it may 

 also be known by the less transverse thorax, and by having the 

 elytra more compressed at the sides before middle, and also by their 

 stronger sculpture. Black, shining, with slight bronze reflection ; head 

 large and convex, with a very strong impression in the centre ; thorax 

 convex, sti'ongly margined, not strongly transverse, with the sides 

 rounded in front and narrowed behind, plainly margined, with the 

 transverse furrows in front and behind more marked than in 

 A. pusiUus ; centre of disc rather strongly, but not closely, punctured ; 

 elytra elongate, with well-marked shoulders; widest behind the middle 

 and thence narrowed to apex, with rather regular punctured strife, 

 which become confused and more or less obsolete towards apex ; legs 

 nigro-peneous. L. 2|-3 mm. 



Parkhurst Forest, Isle of Wight ; a considerable number of 

 examples taken by sweeping rushes in flower by Mr. Donisthorpe, who 

 introduced it as British (Ent. Record, 19()o, p. 2C5). The specimen of 

 A. ^yusiUns x'ecorded by myself (Brit. Col. iv. p. 71) as captured at 

 Carisbrooke Castle, Isle of Wight, and then lost, must, as Mr. Donis- 

 thorpe has pointed out, be pi-obably referred to this species, and this 

 locality for A. 2ncsiUics inust therefore be deleted. 



ELATERIDiE. 



CARDIOPHORUS, Eschscholtz. 



C. erichsoni, de Buysson (Elat. p. .318). Elongate-oblong, rather 

 depressed, black, shining, without metallic reflection ; pubescence veiy 

 fine and scanty, brown on the upper side ; head finely and thickly 

 punctured ; antennfe black, longer in the male than in the female ; 

 thorax longer than broad, subparallel ; sides slightly roimded, extremely 

 finely and thickly punctured, almost smooth except under a high 

 magnifying power ; elytra oblong, more or less attenuated behind, with 

 deep and strongly punctured stria? ; interstices finely sculptured ; legs 

 red ; tarsi black or brown. L. 7-9 mm. 



Lundy Island (Joy and Tomlin), in some numbers at the roots of 

 grass and under small stones, April 1906. The Cardiophorus recorded 

 by Mr. Champion, which was taken by Mr. Dunsmore at Corkendale Law, 

 in Renfrewshire (Ent. Mo. Mag. xiii. 1877, 227), as C. ri(Jipes belongs 

 to the same species. C. erichsoni has occurred in France, Germany, 

 Austria and Russia, and is found on pines at the end of May and the 

 beginning of June : its occurrence, therefore, on Lundy, which is quite 

 treeless, is very strange. Melanotus rufipes, however, another bark- 

 feeding insect, also occurs on the island. 



De Buysson has separated G. erichsoni from C. rufijyes mainly on 

 account of its brown (instead of grey or black) pubescence, the absence
