E. scanicus, Payk. Oblong, testaceous, unequally clothed with 

 pale cinereous hairs ; head round, pitchy-black, thickly punctured ; eyes 

 black, depressed ; rostrum testaceous, about the same size as in the pre- 

 ceding species, rather smooth, sometimes pitchy at base ; antennas 

 entirely pale testaceous ; thorax narrowed in front, a little dilated and 

 rounded at the sides, testaceous, thickly and minutely punctured ; elytra 

 scarcely twice as broad as the base of thorax, with the sides subparallel, 

 with deep punctured striae, and flat, rather smooth, interstices, rufo- 

 testaceous, with a large pitchy-black patch at the base, sometimes, how- 

 ever, extending beyond the middle of the elytra, and sometimes partially 

 broken up by the rufous ground colour, outer margins pitchy ; the

On the female catkins of PopvJ.us tremula and alba and also on Salix cinerea; 

 introduced as British by Mr. Walton (whose description of the species is mainly 

 given above) on a single immature specimen taken by Mr. Wolla&ton in Lincolnshire ; 

 it is also recorded in McNab's Dublin list as from Fortmarnock ; there may, how- 

 ever, be some mistake as to the latter locality. 



TYCHIINA. 



This tribe is here regarded as containing the three genera Tychtw, 

 Mia:otrogus and Siiinia, which are very ciosely allied and are placed 

 together under one genus by Thomson and Bedel and other authors ; 

 the species may be recognized by the structure of the second ventral seg- 

 nit-nt which has its apical margin deeply excavate in a broad semicircle, 

 and is produced at each of the margins in a point over the third geg-
