 to the plate ; and as to its colouring, I will not do it 

 the iRJustice to attempt a description of its rich perfec- 

 tion, more especially as almost every reader may hope 

 to add the insect to his collection during his first year's

The under side, however, presents a remarkable con-

 shades and streaks of funereal blacks and browns. This 

 affords a strange effect when the insect, sitting on a

 thorny.
