ACANTHOCXNUS, Stephens. (Astynomus, Stephens.) 



The members of this genus may be known by their exceedingly long 

 nntennae, which, in the male, are several times longer than the body ; 

 the thorax has a lateral spine on each side behind middle ; the anterior 

 coxee 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 h'vo 

 European species one occurs in Britain. 



The larva of A. (edilis is described by Schib'dte (Pars ix. p. 424) ; it does not 

 differ much from those of the other Lamiidao which nre especially characterized by 

 the absence of legs; the form is slightly narrowed behind ; there are two ocelli on 

 eiich side, which nre 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 

 jui pa is figured by Westwood (Classification 5., p. 363, fig. 44, 4) ; it is very strongly 

 imrrowcd behind, and has the long antenna; curled round iu a loop so that the apex 

 just rests upon the eyes. 



A. cedilla, 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, antennae 

 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 disc, and with the 

 lateral spines short and blunt; elytra more coarsely punctured in front
