Note A. 



I find that Ahrens has figured an apparently distinct species of the genus 

 Rhysodes, (under the name of Rh. Europmis,) in his Faun. Ins. Eur. fasc. 6, f. 1. 

 In consequence of this work being of considerable rarity, and the figures but 

 indifferently executed, I have not thought it necessary to suppress my figure. 



Gyllenhal mentions the Rhys, exaratus in the Appendix to the 3rd Vol. of his 

 Insecta Suecica, p. 720, " quod forte proprii generis, Cucujis quodammodo affine," 

 and considers the Ipsmonilis of Olivier to be congenerous. In the 4th Volume 

 of the same work, p. 332, he has described the insect, and states that the palpi 

 are all filiform, " articulo ultimo elongate lanceolato," and that the maxillat 

 are " brevissima;, apice setosse." 



Note B. 



Having examined the structure of the under side of the head of a specimen 

 of Dendrophagus crenatus, recently received from Germany, I find that it very 

 nearly resembles that of Vleioiajlavipes. The anterior tarsi exhibit the rudi- 

 ment of a basal joint.
