“ Nothing can exceed the dazzling brilliancy of colours united in this little creature. It is, however, more remarkable from the extraordinary construction of its wings, the outer quills of which are greatly curved, and the shafts dilated to a most disproportionate size; a similar structure occurs also in the Broad-shafted H. B. of Dr. Shaw, (T. latipennis.) That it is intended to fulfil some important office in their economy, will admit of no doubt, for in wisdom are all things made; conjecture must, however, in numberless instances, supply our want of real knowledge ”
