 and two firil: annulations of the abdomen, crimfon with gold fpots. 

 Thorax with two teeth. 



The Chryfis Bidcntata 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 dirediion of light, blue, in another green, in another purple, &c. 

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

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

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

 fraali gold fpots which befprinkle it, greatly dimJnifh the ftrength of 

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

 infeci. 



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