6 LAMKLLICORNIA. 



or distinctly on disc, somewhat rugosely at sides ; elytra a little more 

 strongly punctured than in male, and the external spine on tibia} more 

 pronounced. L. 15-20 mm. 



In rotten wood of ash, elm, &c. ; often found on palings and sometimes in cellars nnd 

 tables; London district, rather common and generally distributed ; Kent ; Glanvilles 

 Wootton ; New Forest ; Devon ; Swansea ; Bath ; Gloucester; Bewdlcy ; Birmingham 

 district ; Shrewsbury ; Repton ; Sherwood Forest ; Lincoln ; Church Stretton, 

 Cheshire ; it appears to cease further north in England, and has not occurred in 

 Scotland ; it may, however, be regarded as of general occurrence from the Midlands 

 southwards; one specimen has occurred at Armagh in Ireland (Rev. W. F. Johnson). 



SINODENDRON. Fabricius. 



This genus contains three or four species, one from Europe and the 

 others from North America ; they are by Thomson and others raised to 

 the position of a distinct family, Sinodendridae ; they are easily dis- 

 tinguished from the members of the two preceding genera by having the 

 eyes entire, the posterior femora not extending beyond the margin of the 

 elytra, and the elytra more or less distinctly striate. The larva is 

 beautifully figured by Schiodte (De Metamorphosi Eleutheratorum, 

 Part viii. Fig. xviiL 1); it does not differ materially from the ordinary 

 Lucanide form ; the head is rather small, and the front part of the body 

 considerably thicker than the hinder part, which appears to be less 

 curled up towards the abdomen than is usually the case ; it lives in wood 

 of ash, willow, &c., and sometimes does considerable damage, although 

 it appears chiefly to attack trees that are either decayed or about to 

 decay, and therefore its ravages are more apparent than real. 



S. cylindricum, L. (juvenile, Muls.). Oblong, cylindrical, parallel- 

 sided, very convex, shining black, very strongly sculptured ; head small, 

 strongly punctured, with a rather long recurved horn in the male, which 

 is furnished behind towards apex with long yellowish hairs ; in the 

 female the horn is reduced to a larger or smaller tubercle, and is glabrous ; 

 thorax ttrongly depressed in front, very strongly punctured behind 

 depression, more closely in female than in male, with smooth central 

 line ; in the latter sex the anterior angles of the thorax are very promi- 

 nent, and the anterior depression is furnished with large and very shallow 

 punctures ; its posterior margin is strongly raised and tridentate, the 

 central tooth being large and blunt, and almost taking the form of a 

 short horn ; in the female the anterior angles are not prominent, and the 

 depression with its margins and teeth are evident but much lesf 

 apparent, the latter being merely indicated by blunt prominences ; 

 scutellum smooth ; elytra very strongly punctured and more or less dis- 

 tinctly striated, with a row of smaller punctures on each side of suture ; 

 antennae ferruginous or pitchy red ; legs black, with tarsi lighter, strongly 

 spinose externally. L. 8-12 mm. 



In rotten ash, beech, willow, Ac. ; generally distributed throughout England and
