GENERIC CHARACTER. 



Thorax joined to the abdomen by a fhort pedicle. Abdomen divided 

 into three fegments. Sting fimple. Wings not folded. Antennae fili- 

 form of one long and eleven fhort joints each. 



SPECIFIC CHARACTER. 



Head and laft fegment of the body, fky blue, changeable. Thorax, 

 and two "fxrft annulations of the abdomen, crimfon with gold fpots. 

 Thorax with two teeth. 



The Chryfis Bidentata is fcarcely fo large, and by no means fo 

 common as the Chryfis Ignita, (not exceeding one-third of an inch in 

 length) but is equal, if not fuperior. in beauty and richnefs of colour. The 

 head, but more particularly the laft fegment of the body, appears in 

 one direction of light, blue, in another gieen, in another purple, &c. 

 and the thorax, and two firft fegments of the abdomen are far more 

 enriched with a golden appearance ; the ground colour is deep crimfon, 

 but the metallic appearance on the lighter parts, and the number of 

 fmall gold fpots which befprinkie it, greatly diminifh the ftrength of 

 colour, and renders it, even before it is magnified, a fuperb little 

 iniecl. 



It is found in May or June in fome parts of Kent and Effex.
