Gractlia. | LONGICORNIA. 227 
darker fuscous or fuscous red colour, upper surface very finely punctured, 
rather dull; eyes black, very strongly emarginate; thorax longer than 
broad, subcylindrieal, slightly dilated at sides, rather uneven ; elytra 
with more or less obsolete depressions towards base ; abdomen shining, 
black or dark brown ; legs reddish-brown, with the femora strongly and 
broadly clavate. L. 31-5 mm. 
Male with the antenne plainly longer than the body, and the thorax 
a third part longer than broad ; in the female the antenne are a very 
little longer than the body, and the thorax not quite as long as in the 
male. 
In dead twigs, in hedges, &c.; often in old baskets and hampers; locally common ; 
London district, not uncommon and widely distributed ; Dover ; Portsmouth district ; 
Devon; Hastings; Bristol; Cambridge; Repton, Burton-on-Trent; Sunderland 
(two specimens, perhaps imported) ; not recorded from Scotland. 
OBRIUM, Latreille. 
Eighteen species have been described as belonging to this genus, 
which will probably prove to be considerably more extensive; they are 
very widely distributed, having been found in Africa, Japan, Ceylon, 
North and South America, Tahiti, Sarawak, the Fiji Islands, &c.; three 
have occurred in Europe; they are rather slender and graceful insects, with 
very large eyes and very long antenne; the thorax is considerably longer 
than broad ; the anterior coxal cavities are closed behind, and all the 
coxe are nearly contiguous ; the first segment of the abdomen is con- 
siderably longer than the following ; the closed anterior coxal cavities 
will separate our single species from all the other British members of the 
tribe except Molorchus, from which it may be known by having the ab- 
domen completely covered by the elytra; the species is very rare as a 
rule, but has been bred by Dr. Power in some numbers from aspen bark; 
for three years specimens came out of the same bark. 
O. cantharinum, L. ( ferrugineum, F.). A very graceful and pretty 
species ; elongate, finely pilose, with the head and thorax more shining 
than the elytra, of a pale reddish-testaceous colour, with the eyes black, 
and the antennz and legs more or less blackish or brownish, the base of 
the former, and the club of the femora of the latter being darker than 
the remainder ; head with eyes broader than thorax, antennz very long, 
considerably longer than the body ; thorax longer than broad, dilated 
and tuberculate at sides, almost smooth on dise, at all events in the male; 
elytra rather depressed, irregularly and distinctly punctured; abdomen 
with the first segment considerably longer than the second. L. 6-11 
mm. 
Male with the first segment very long, and the second and third emar- 
ginate at apex and thickly pubescent. 
In aspens, apple trees, &c. ; very rare; Wanstead, bred in some numbers (Power) 
Epping, Leytonstone, Broxbourne, and Brighton (Stephens).
