10 THE ENTOMOLOGY OP THE (JRASS-TUEES, 



leaves, clasping the foliage with its legs, but dropping to the 

 ground at the least alarm. 



Beetle 5 linens in length, with the head bright metallic green, 

 thorax and elj^tra of a much darker tint, the whole deeply and 

 closely punctured; sides of the thorax ornamented with a pale 

 buff patch on either side, with four transverse ruws of the same 

 coloured oval spots, the first and last containing two and the 

 middle ones four each; undersurface of a bright metallic green, 

 with a patch of buff below the hind legs, and at the margin of 

 each abdominal segment. 



Tkigonotarsus rugosus, Boisd. 



(Plate IX., figs. 1-3.) 



Larva with smooth castaneous head; thoracic segments pale 

 reddish-brown and not more than lialf as thick as the centre of 

 the pale yellow abdominal ones, which are generally arched up 

 behind the head; length in repose about an inch, but when 

 moving about it extends its body half as far again; thoracic 

 segments rather flattened upon the dorsal surface, with the 

 abdominal ones of a uniform length and very much wrinkled; 

 anal one terminating with two short truncate tubercles of a 

 reddish-brown colour, with several smaller ones round them. 



The larva? bore holes into the fibrous caudex near the bottom 

 of the trunk of the grass-tree, where they must feed for some 

 time, as I have taken the larva", pupa*, and beetles in the same 

 tree about the middle of the year. 



Pupa 14 lines in length, white to dull yellow in colour; snout 

 very thick, and curved straight down over the breast, both it and 

 the rest of the head lightly clothed with stout bristles, which 

 also extend over the sides of the thorax; wing-cases drawn round 

 the shoulders, short, and rounded at the tips, and deeply and 

 regularly striated; thoracic segments bearing a transverse ridge 

 of coarse irregular spines across the centre of each segment 

 except the anal one, which is ornamented with a crescent-shaped 

 mark turning downwards, clothed with a few scattered hairs.
