Throivu'lioiit the State; frequent. !\!ay 21-()ctober 23. Occurs 

 on morning-iiloi'v, bittci'swtMt and sweet i)(»tat(> vines; commonly 

 known as the ■\u()l(l-l)ug'" and in life one of the most brilliant of our 

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

 changing its hues, at one tinu' apix'.iritu^' only of a dull yellow color, 

 and at other times shining with the splendoi- of ])olished brass or 

 gold, tinged sometimes also with llie \ariable tints of pearl. The 

 wing covers, the ])ai'ts which exhibit a change of color, are lined be- 

 neath with an orange colored })aint, which seems to be filled with 

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

 brilliancv of the insect."
