78 COLEOPTERA. 



cies now under consideration differs totally in habitus from 

 its congeners, its impunctate semi-opaque surface, long, slender, 

 obsoletely armed legs, its pitchy red colour and sub-globose 

 form, alienate it from the Saprini; but M. de Marseul, who 

 has bestowed especial attention on the JEListeridce, and whose 

 elaborate Monograph of the family, above cited, is well 

 known to many of our readers, places this species in the genus 

 Saprinus, remarking " Elle a un facies tout different des 

 autres Saprinus, on dirait un Tribalus on un Dendrophilus ; 

 mais aucun caractere de valeur ne la separe de ce genre." 

 I cannot, however, resist the conviction that future inves- 

 tigation will assign this insect to a distinct genus; lack of 

 specimens at present precludes me from entering farther on 

 the subject. 



24. Nitidula flexuosa, Fab. Erich., T. J. Bold, Zool. 

 5111 (1856). 



Mr. Bold considers that the specimens taken by him, near 

 Newcastle-upon-Tyne, were probably introduced, and that 

 the species cannot, upon their testimony, be looked upon as 

 truly indigenous. 



Genus OXYLiEMUS, Erich., Naturgesch. d. Insect. 

 Deutschl. iii. 282 (1845). 



The species constituting this genus, of which the two fol- 

 lowing are the sole recorded representatives, bear on a cursory 

 view, a certain resemblance to some of the members of the 

 genus Rhyzoj)hagus, from which, however, they may be at 

 once distinguished by their more cylindrical form, quadri- 

 foveolated thorax, coarse sculpture, and tetramerous tarsi; 

 other characters, on which I must not now enter, involving 

 their location in a distinct family, have been elicited by the 

 patient investigation of Erichson, who places this genus 

 among the Colydidce, group Colydini, after Teredus. 

 Oxylcemus differs from Teredus in having the antenna?
