396 RHYNCHOPHORA. [ Codiosoma. 
in Britain, but is sometimes found in abundance on our South-Eastern 
coasts in old decaying wood on the sea-shore, 
C. spadix, Herbst. Convex, dark pitchy-brown or reddish, shining, 
with fine grey pubescence, which is recumbent on the thorax and some- 
what raised on elytra; rostrum narrower and longer than the head, a 
little longer in the female than in the male, antenne comparatively 
slender, with the club oval ; thorax suboval, rather longer than broad, 
strongly punctured ; scutellum invisible ; elytra oval and convex, with 
deeply punctured striz, interstices narrow, with rows of punctures, and 
transversely strigose. L. 3-35 mm. 
In old posts, on the sea-shore and on the banks of large rivers near their mouths ; 
locally common; Harwich (Walker); Gravesend (Janson) ; Sheerness (Walker) ; 
Dovercourt ; Walton-on-Naze ; Pegwell Bay (common, T. Wood) ; Hastings district ; 
Eastbourne ; near Cowes (Gorham) ; Seaford, Devon. 
MAGDALINA., 
This tribe is made up almost entirely of the single genus Magdalis, 
taken in its wide sense; the following are its chief characteristics ; 
form elongate, upper surface glabrous or almost glabrous ; thorax with 
the anterior angles projecting, often sharp and considerably prominent ; 
elytra separately rounded at base and advanced towards thorax ; anterior 
coxe contiguous ; thorax at base a little narrower than elytra, not or 
scarcely transverse ; femora usually, but not always, armed with a tooth ; 
tibiz short, shorter than the femora; tarsal claws usually simple, but 
occasionally toothed at base ; pygidium exposed in both sexes. 
MAGDALIS, Germar. (Magdalinus, auct.; Thamnophilus, Schon. ; 
Rhinodes, Steph. ; Panus, Steph. pars.). 
This genus contains about forty species which are scattered over the 
greater part of the Northern Hemisphere; one has been described from 
Brazil and another from the Australian region ; they are deep black or 
biuish insects (rarely, in the case of some foreign species, reddish), as a 
rule without a trace of pubescence, and may be known by the characters 
above given; many live on fir and pine trees, and the remainder on the 
oak, elm, birch, black poplar and various fruit trees; the larvee undergo 
their transformations in the small branches of the trees and form galleries 
under the bark or in the wood; the sexual differences are often very 
distinct, the males having the rostrum shorter and duller than in the 
female and the club of the antenne sometimes very strongly developed ; 
of the twenty-six European species eight are usually regarded as British ; 
these may be distinguished as follows :— 
I, Anterior femora armed with a strong sharp tooth 
(Magdalis, i. s.p.).
