Rhynch'ite*.] RHYXCHOPHORA. 127 



head finely punctured ; thorax with the sides rounded and dilated, disc 

 moderately, closely, and regularly, but not strongly punctured, with 

 a more or less distinct central furrow ; scutellum rather small ; elytra 

 with rather shallow punctured striae, the punctures being moderately strong 

 towards base and obsolete at apex, which is almost smooth ; antennae 

 black ; legs unicolorous with body, rather strongly pubescent. L. 6f- 



On young hazel, birch, oak, <tc; in woods; not common but rather widely dis- 

 tributed from Lincolnshire southwards ; it appears often to oc2ur by single specimens ;

 Portsmouth District ; Fordlands, Devon ; Bewiiley ; Coventry ; Robins Wood and 

 Bretby Wood, Repton ; Langworth Wood, Lincoln ; I know of no locality further 

 north. 



This is a large and conspicuous species and may easily be known by 

 its size, very strong villose pubescence, and by the fact that the striae of 

 the elytra become obsolete at apex. 



DEPORAUS, Leach. 



This genus, as characterized by Bedel and Sharp, includes two British 

 specie?, of which one, D. megacephaltis, was regarded by Stephens and 

 Leach as belonging to Rhynchites proper ; they are, however, very closely 

 allied in several points, and the characters of the genus as now constituted 

 are more satisfactory than those assigned to it by the old authors ; a 

 third species, D. tristis, occurs in France ; the females roil up cases of 

 leaves for their larvae, as in the other genera. 



I. Elytra greenish-blue; shape narrower and more elon- 



gate; male with the posterior femora not dilated D. MKGACKPHALUS, &erm. 



II. Insect entirely black ; shape broader and less elon-

D. meg-acephalus, Germ, (const rictus, Gyll., Icericollis, Steph., 

 Mannerheimi, Hummel). Black, or greenish-black, with the elytra 

 greenish-blue, clothed with thin and fine greyish pubescence ; rostrum 

 dilated at apex, sulcate at base ; head large, together with eyes a little 

 broader than thorax, vertex long, diffusely and plainly punctured ; thorax 

 subovate, rounded at sides, closely and rather finely punctured ; elytra 

 much broader than thorax, with deep and regular punctured striae, inter- 

 stices slightly convex and obsoletely punctured in rows'; legs blue-black 

 with the tarsi scarcely shorter than the tibiae and the first joint elongate ; 

 in the male the rostrum is shorter than in the female. L. 3-4 mm.
