I have a British specimen of this insect, already attributed 

 to us by Mannerheim, evidently through rujicollis, Marsh., 

 being erroneously attributed to it as a synonym by that 

 author, — who also credits our lists with L. rugicolllsy 01., 

 kirtus, Schiipp., and rngosus, Hbst., Corticaria longicornisy 

 Hbst., linearis, Payk., and similata, Schiipp. ; all of which, 

 save L. rugosus, detected here long after the publication of 

 Mannerheim's work, are apparently considered British by 

 him through Stephensian errors. 



X. const7'ictus is closely allied to L. carinatus, Gyll., but 

 is rather smaller, narrower, and of uniformly lighter colour, 

 with the thorax especially longer and narrower and divided 

 as it were into two lobes, of which the anterior is much the 

 larger, and very rounded at the sides, with no trace of any 

 angle in front. 



Thomson founds his genus Coninomns on these two 

 species, conspicuous for the two-jointed club of their antennae. 

 See Kraatz, Berl. Ent. Zeit., xiii, p. 129. 



De Marseul sinks constrictus as a syn. o^ limhatus, Forst., 

 — repeating, however, the latter name by itself at the end of 

 the genus, as if unknown to him ; but Kraatz states that it 

 is carinatus that is identical with Forster's species.
