232 MODERN CLASSIFICATION OF INSECTS. 



of the generic groups established by the more recent continental au- 

 thors. The indigenous or reputed indigenous species may be accor- 

 dingly generically arranged as in my Synopsis. 



Of these indigenous insects, the species of AjithaxicE are small but 

 elegantly coloured insects, of a rather broad form ; the Agrili and 

 Aphanistici, on the contrary, are linear. All the British species of 

 this family are very rare, except the Agrilus viridis, which is repeat- 

 edly taken in the neighbourhood of London, especially at Coombe 

 Wood, on the oak. The species of Trachys are minute ; but easily 

 known by their short subtriangular form. The typical species (T. mi- 

 nuta,^^. 23. 14.) is of a bronzed black colour, ornamented with grey- 

 ish waived lines. It is found upon the hazel, upon the leaves of 

 which it is said to feed. I have always found the Aphanisticus pu- 

 sillus in dry moss, at Coombe Wood, in the spring. This genus is 

 distinguished from all the other Buprestidae by its clavate antennae 

 (/7^.23. 15.). 



Amongst the exotic genera, in addition to those already noticed, 

 may be mentioned that of the Sternocera, composed of various large 

 and splendid Indian species, in which, as the name implies, the me- 

 sosternum is produced into a spine, covering the base of the proster- 

 num, in which respect it agrees with the Cetoniidae. 



The second family Eucnemid^* (which, as above stated, must be 

 regarded as provisional only) comprises the two small groups termed 

 by Latreille, in the Memoir above referred to, Eucnemides and Ce- 

 rophytides. They are jointly characterised by their inability to leap, 

 the large terminal joint of their palpi, their antennae often pectinated 

 or serrated, and sometimes lodged, when at rest, in grooves on the
