396 RHINCHOPHOBA. [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, antennae comparatively 

 slender, with the club oval ; thorax suboval, rather longer than broad, 

 strongly punctured ; scutellum invisible ; elytra oval and convex, with 

 deeply punctured strise, interstices narrow, with rows of punctures, and 

 transversely strigose. L. 3-3| mm. 



In old posts, on the sea-shore and on the banks of large rivers near their mouths ; 

 locally common; Harwich (Walker); Gravesend (.lanson) j 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 Magdalig, 

 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 

 coxae contiguous ; thorax at base a little narrower than elytra, not or 

 scarcely transverse ; femora usually, but not always, armed with a tooth ; 

 tibiae short, shorter than the femora ; tarsal claws usually simple, but 

 occasionally toothed at base ; pygidium exposed in both sexes. 



IKAG-D AXiXS, Germar. (Magddlinus, 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 

 bluish 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 larvas 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 antennae 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
