A SPLENDID GENUS. 213 



generally comparatively plain in Beetles, the same arrangement 

 of green spots on a coppery ground prevails. This, like the 

 preceding insect, is a native of the Philippines. 



Of these Beetles there are very many species, the greater 

 number inhabiting the Philippines, but others being found in 

 Australia, New Guinea, and Polynesia. Many of them have 

 not yet received names or been entered in the catalogue of 

 acknowledged species. There is an infinite variety of colouring 

 among them. Black is the usual ground hue, and green the 

 prevailing colorn- of the pattern. Next in frequency to green 

 comes red, and then copper, all these colours being produced by 

 scales which are visible with an ordinary pocket magnifier.

 those of the preceding insects are only curved. 



The insect which is here figured is all black, rather shining 

 above and dull below. It is a native of New Holhind. 



Tliere is scarcely any portion of the upper surface of this insect 

 which is quite smooth, those parts which are not knobbed being 

 grooved. The upper part of the head has a wide and rather 

 deep groove. The thorax is rounded and covered with knobs, 

 which are comparatively scanty on the disc, but become very 

 numerous and crowded on the sides. These projections are 

 without any apparent order, but those of the elytra are arranged 

 in three distinct rows. The elytra are very large, and are 

 turned over the sides rather abruptly. On tlie edge where they 

 are folded, is a row of nine knobs, so long and pointed that they
