 Habitat : China. 



Head green. Antennaj black, and shorter than the thorax ; having at each joint some short hairs. 

 Thorax green, and margined, appearing as if finely polished ; the hinder corners being pointed, and 

 forming obtuse angles. Scutellum round and shining. Elytra likewise green, shining, and margined ; 

 their extremities terminating in two sharp points. Under side shining green, except the tarsi, which are 

 black. 



This beautiful insect may be regarded as the most brilliant species belonging to the 

 family, Elateridae, the majority of which are of dull and uniform colours, thus affording 

 a strong contrast to the splendid family of Buprestidse, to which they are very nearly allied. 

 The family Elateridae are all, as Drury observes, provided with an instrument which ex- 

 tends along the breast, about the thickness of the thighs, to the abdomen, where the end 

 of it is received into a groove, forming a spring, by which the creature, when laid on 

 its back, can jump to a considerable height, fi-oni which circumstance it has received the 

 name of Elater.

Head dark brown. Antennae longer than the insect; the sixth joint being furnished with a small 

 tuft of hairs. Thorax brown, very rough and uneven, occasioned by the many bumps or swellings on 

 it ; two of which, like thick spines, are situated on the sides. Scutellum small. Elytra brown, and full 

 of small pustules. In the middle are two oblong black streaks, placed next the suture. Legs brown, 

 femora very thick. Tarsi yellow underneath, and pilose ; those of the fore-legs being very hairy.
