ACANTHOCINUS, Stephens. (Astynomus, Stephens.) 
The members of this genus may be known by their exceedingly long 
antenne, which, in the male, are several times longer than the body ; 
the thorax has a lateral spine on each side behind middle; the anterior 
coxse are rather widely distant, and the intermediate pair still more so; 
the posterior tarsi have the third joint clothed with pubescence beneath ; 
in the female the sixth segment of the abdomen is much produced, and 
the ovipositor is exserted. The genus contains thirty-two species, which 
are widely distributed from Siberia to Tasmania; several species have 
been described from Mexico and the Amazon district; of the five 
European species one occurs in Britain, 
The larva of A. edilis is described by Schiddte (Pars ix. p. 424); it does not 
differ much from those of the other Lamiidz which are especially characterized by 
the absence of legs; the form is slightly narrowed behind; there are two ocelli on 
each side, which are rather large and convex; the anal segment is trifurcate; the 
whole upper surface is rather thickly pilose; the larva lives in wood of pine; its 
pupa is figured by Westwood (Classification i., p. 363, fig. 44, 4); it is very strongly 
narrowed behind, and has the long antenne curled round in a loop so that the apex 
just rests upon the eyes. 
A. xdilis, L. (montanus, Serv.). A large and conspicuous species of 
rather short and broad form, fuscous brown or chocolate brown, thickly 
clothed with greyish pubescence; head narrower than thorax, antenne 
very long, widely distant at their insertion, ringed with white ; thorax 
strongly transverse, coarsely and not closely punctured, with four yellow 
pilose tubercles placed transversely on front of dise, and with the 
lateral spines short and blunt; elytra more coarsely punctured in front.
