230 MANDIBULATA.— ^COLEOPTERA. 



most coarsely at the base, and each with three very ohsoletely elevated lines : 

 legs and antennse bluish. 

 Extremely variable in tint: sometimes bluish-green above, or bright grassy 

 metallic green ; occasionally of a rich coppery or golden green : the legs and 

 antennae are at times tinted with the same hue : and the thorax is occasionally 

 rather coarsely wrinkled, and at other times extremely smooth and glossy. 



Abundant on tlie trunks of willows in July, in many places 

 throughout the metropolitan district, especially in Battersea fields; 

 also found in Devonshire and other parts of the country. " Common 

 near Ely." — Rev. L. Jenyns. " York, once." — W. C. Hezaitson, 

 Esq. " Near Penllergare and in Crwmlyn-bog, not common," — 

 L. W. Dillzoyn., Esq. 



Genus CCCLXVIII. — Monochamus, Megerle. 



Palpi with the terminal joint elongate-subfusiform ; maxillary much longer 

 than the labial. Antennoe longer than the body, especially in the males ; basal 

 joint slightly robust; second minute, nodose; remainder gradually decreasing 

 in length and thickness to the apex, which is acute: head robust, inflexed: 

 eyes elongate, lunate : thorax short, cylindric, with an acute spine on each 

 side : elytra elongate, convex : legs elongate : tibiae slightly curved, inter- 

 mediate, with an obtuse denticulation in the middle of the external edge. 



From Cerambyx the somewhat cylindric, convex, elongate body, 

 greater slen^rness and length of antennae, dissimilarity of palpi, 

 and distln(/tly unidentate intermediate tibise, with the curvature of 

 the latter, sufficiently distinguish the present genus.
