Euenemide. | SERRICORNIA. 
i, Antenne moderately distant, simply serrate in both 
sexes ; elytra without trace of strie . . . . . . HUCNEMIS, Ahr. 
ii, Antenne approximate, pectinate in male (in our 
species) ; elytra with strie more or less distinct . . MicroRRHAGUs, Eschs. 
MELASIS, Olivier. 
This genus comprises three or four species, one of which is found in 
Europe, and the others have been described from North and Central 
America ; they are elongate and cylindrical, and live in wood in which 
the larvee bore galleries, or, according to some authors, are parasitic on 
certain wood-boring insects. 
The larva of Melasis buprestoides is described and figured by Schiddte (Part v. 
p. 49, plate iii.); it much resembles the larve of certain of the Buprestidae, the 
head being very small and sunk in the prothorax, which is broader and much larger 
than the meso- and metathorax; the antenne are very minute, and the maxille and 
labium are obsolete; the abdominal segments are all much longer than the meso- 
and metathorax, and are all transverse with the exception of the ninth, which is 
conical and obtuse and not furnished with cerci; there are no scuta, except on the 
prothorax; the spiracles are of a short ovate form, those on the prothorax being the 
largest ; the legs are obsolete ; the larva is white, with the clypeus and mandibles 
ferruginous. 
IM. buprestoides, L.(¢ v. elateroides, Ill.). Elongate, cylindrical, 
clothed with fine and sparing greyish pubescence, dull black, with the 
antenne and legs fuscous or pitchy red, elytra sometimes lighter than 
the front parts; head large, vertical, rather thickly and coarsely 
punctured ; antenne varying somewhat in the sexes; thorax broadest 
in front, very gradually narrowed to base, coarsely sculptured, posterior 
angles projecting; elytra long, gradually narrowed to apex, rather 
deeply striated, interstices narrow, thickly punctured and granulate ; 
legs rather stout, tibie suddenly and strongly narrowed at base. L, 
6-8 mm. 
Male with the antenne flabellate from the sixth joint, and the thorax 
distinctly channelled ; female with the antenne pectinate and the 
thorax channelled at base. 
In rotten wood of beech and other old trees; local, but sometimes in numbers 
where it occurs ; Chatham (Champion and J. J. Walker, in profusion) ; Sevenoaks ; 
Coombe Wood; Cobham Park; Darenth Wood; Tonbridge; New Forest; Windsor 
Forest ; Halesworth, Suffolk ; Bretby Wood, near Repton (Harris); Dunham Park, 
Manchester (Chappell). 
EUCNEMIS, Abrens. 
This genus appears to contain only one species, which is widely dis- 
tributed in Europe, but has only lately been taken in Britain; the 
larva has been described and figured by Perris, Bonvouloir, and Cussac, 
but has been more accurately discussed by Dr. Sharp in the Transactions 
of the Entomological Society of London, 1886, Part iii. pp. 297-802 ; 
it is chiefly remarkable from the fact that there exist on the dorsal and
