elytra, nnd apical half of each segment of the abdomen riifou?, 

 clothed with grey pubescence, verv finely tuberculate, or alutace- 

 ous ; head moderate^ thorax rather short, widest before the base; 

 elytra short, shorter and narrower than tlie thorax ; abdomen 

 narrow, acutely attenuated, twice as long as the anterior parts of 

 the body ; legs and antenna^ short, robuLt rufo testaceous. 



Differs from all the other species in its slender attenuated 

 form, and rufous colour. 



I am much pleased to be able to add this very elegant species 

 to the British List. Among some unnamed JNIyllfenaj collected 

 by the late Mr, T. Wilkinson, of Scarborough, and kindly sent 

 to me l)y IMr. P. B. ]\Iason, I found two examples of M. f/rcvca, 

 and, as particles of sea-sand were still adhering to both specimens. 

 I have every reason to conclude that they must have been taken 

 on the shore near Scarborough, From a label attached to a type 

 specimen received from M. A. Fauvel, this rare species appears 

 lo have occurred also in Corsica. 



Mylhrna gracilis. 



L. c. 1-1 5 lin. = 2-'l'')() mm. Long and narrow, fuscous- 

 black, clothed with grev puljescence, closelv and strongly tuber- 

 culate ; head large and broad ; thorax small almost quadrate ; 

 elytra longer and broader than the thorax ; abdomen longer than 

 the anterior parts of the body comliinod, much attenuated with 

 the apical and greater part of the penultimate segments rufous ; 

 legs and antenna' rather short, robust, rufo-piccous ; antennae 

 distinctly incrassated towards the apex. 



Differs from other species in its smaller size, short and robust 

 legs and anteniia\ 



M. firdciUs is the most common of the smaller species. 



Mi/lhvna ivfuscata. 



L.c. 3_]i;n. = 1-50-2 nun. Fuscous thickly clotheil with 

 grey ])uliescjnce, closely and rather strongly tuberculate ;

 dilated at the base; eh'tra shorter and narrower than the thorax;
