Ceuthorrhynchus and seems therefore in so far to be more 

 closely allied to Tapinotiis Schønh. than to Amaliis Schønh. 



6. Rhynclntes longiceps Thoms. This name often is 

 stated as a synonym to Rh. tomentosus Gyll. (undnatus 

 Thoms.) (ref. for instance Heyden, Reitter & Weise: 

 Catalogus Coleopterorum Europae pag. 705, Schilsky: 

 Systematisches Verzeichnis der Käfer Deutschlands und 

 Deutsch-Oesterreichs pag. 185, Reitter; Fauna Germanica 

 pag. 263). But this is quite wrong. The species is quite 

 another one than Rh. tomentosus, from which it may be 

 very easily separated by having no spine at the anterior 

 tibiæ, by having the rostrum a little longer in both sexes 

 and by having the striae of elytra a little stronger and 

 the interstices a little narrower. From Rh. nanus Payk., 

 which quite as Rh. longiceps differs from Rh. tomentosus 

 in wanting the little spine in the interior tibiæ, it may 

 be easily distinguished by having the head considerably 

 narrower than the thorax at the broadest point, by con- 

 siderably longer rostrum in both sexes, by more regular 

 punctuation of thorax, by having the scutellar stria evident 

 and by a deeper blue colour. Rh. longiceps Thoms, un- 

 doubtedly has been mixed up with Rh. tomentosus by several 

 authors, for instance Reitter; this may be seen from the 

 fact, that Reitter in „Fauna Germanica" pag. 263 does 

 not at all name, that tomentosus differs from nanus in 

 having a spine at the apex of anterior tibiæ, although 

 this spine is just the best character in separating the species. 



Rh. Harwoodi Norman H. Joy (Entom. Monthly Mag. 

 Sec. Series XXII (1911) pag. 270) is undoubtedly quite 

 the same species as Rh. longiceps Thoms., which name 

 must therefore be applied as being the elder. 



The species is found in Denmark in company with its 

 allied and is not more rare than Rh. tomentosus.
