Throughout the State; frequent. May 21-Oetober 23. Occurs 

 on morning-glory, bittersweet and sweet potato vines ; commonly 

 known as the "gold-bug" and in life one of the most brilliant of our 

 beetles. Of it Harris says: "When living it has the power of 

 changing its hu^s, at one time appearing only of a dull yellow color, 

 and at othci- times shining with tlu^ splendor of polished brass or 

 gold, tinged sometimes also with the variable tints of pearl. The 

 wing covers, the parts which (wliibit a change of color, are lined be- 

 neath with an orange colored ]iaint, which seems to be tilled with 

 little vessels; and these are probably the source of the changeable 

 brilliancy of the insect."
