80 CIAVICORNIA. [Euconnus. 



E. dcnticornis, Mull, (ruficornis, Denny). Rather a large species, 

 convex, black or pitchy-black, shining, with thick bristly pubescence at 

 the sides of thorax and on the temples, antennae and legs ferruginous, 

 femora black or pitchy ; head large, nearly as broad as thorax, antennas 

 rather long and robust ; thorax somewhat cylindrical, longer than broad, 

 narrowed in front, impunctate, with two distinct fovese at base and 

 between them a small fold; elytra oval, convex, almost irapunctate, 

 foveolate at base, with a strong humeral fold; femora dilated. L. 1|- 

 1 mm, 



Male with the first two joints of the club dilated and denticulate, the 

 first longer than broad, securiform, the second subquadrate and strongly 

 toothed at apex ; in the female the three first joints of the club are 

 simple, about as long as broad. 



In moss, vegetable refuse, &c. ; occasionally by evening sweeping ; rare ; Micklc- 

 liam, Esher, Caterham, Dorking, Faversliam, Ashford, Darenth, Surbiton, Purley, 

 Cowley, Chattenden ; Norfolk ; Hollingtou and Guestling, near Hastings ; New 

 Forest; Scarborough. 



E. hirticollis, 111. Of very much the same shape as the preceding, 

 deep black, shining, sparingly pubescent, except on thorax, which is 

 clothed with very thick and long bristly pubescence ; antennas, palpi and 

 legs ferruginous, club of the former and the femora blackish ; head 

 small, somewhat orbicular, with a large neck, antennae long and slender 

 with the joints rather elongate ; thorax longer than broad, somewhat 

 cylindrical, narrowed in front, base transversely compressed, with two 

 indistinct fovese; elytra short oval, impunctate and very sparingly 

 pubescent; legs long, femora dilated at apex. L. 1^ mm. 



Marshy places in wet ir.oss, and at roots of grass ; also under fallen leaves in 

 woods; rare; Faversham, Wejbridge, Caterham; Horning Fen; Wicken Fen; 

 Tewkesbury ; Sutton Park, Birmingham ; it is also recorded from the Southern dis- 

 tricts (Hastings, Portsmouth, &c.), and from the neighbourhood of Durham, and 

 other localities, but many of the records of its capture evidently apply to the following 

 species, which is by far the commoner of the two. 



E. fimetarius, Chaud. (hirticollis, var., Reitter, &c.). Very closely 

 resembling the preceding species, but with the penultimate joint of the 

 palpi fuscous, and the hairs on the elytra shorter and less scattered ; the 

 chief difference, however, lies in the formation of the antennae, which are 

 evidently shorter and more thickened towards apex, and have the joints 

 less elongate ; according to Thomson the male has the penultimate seg- 

 ment of the abdomen impressed in the middle at apex, and the posterior 

 margin subtruncate. L. l mm. 



In haystack and vegetable refuse ; rather local ; London district, not common, 

 Dorking, Esher, Putney, Bromley, Shirley, Merton, Darenth, Hammersmith ; Sheer- 

 ness; Tonbridge ; The Holt, Farnham ; Glanvilles Woo t ton ; Repton, Burton -on - 

 Trent; Durham district ; Scotland, very rare, Forth district. It appears to be com- 

 inoncr than E. hirticollis; its habitat is different, and it may easily be distinguished 

 Ly the formation of the antennae ; the two species are very often mixed together, but
