to the slightest change of light. This crimson line is strongest 

 near the base and upon any projections. Each of the jaws has 

 a bold curve downwards, and at the base is an enormous tooth, 

 boldly curving forwards, and so large as almost to look like a 

 second jaw. These teeth are never exactly of the same length, 

 that of the right jaw being generally, though not always, larger 

 than that of the left, .and when the jaws are closed these teeth 

 meet each other. The whole inside edge of the jaws is covered 

 with small teeth, so that what with these little teeth and tlie 

 large teeth at the base, the hold of the jaws is extremely 

 powerful.

Measured along the curve, tlie length of jaw in a fine speci- 

 men is no less than two inches and a half, while from base to tip 

 in a straight line it is not quite two inches. 



The head and throat are dark, metallic, shining green, glossed 

 like the jaws with carmine, this gloss being very conspicuous at 

 tlie hinder angles of the thorax, which project in two long and 

 sharp spikes. There is a curious tuft of hair on the antennae, 

 just where the lamellae begin. 



The legs are coloured much like the jaws, and are armed with 

 a multitude of thorny points.
