M. OTHER INSECTS. 
We find in all orders of insects some species that occasion- 
ally attack man and animals and that may injure either 
by their bite or by their poison. None of them can, how- 
ever, be called true parasites. 
Among the butterflies and moths we have a few whose

in which hard wood is sawed. In running over the persons 
engaged in mill work they become not simply annoying, but

sores caused by them. They seem to prefer the neck of their 
victims, and notwithstanding their small size, as indicated 
by the line in the illustration, their bite is a painful one.
