consequence of their attacks, people found it impossible to remain in

Ceratopogon pulicaris measures 2 mm. in length, and is therefore

The Harvest Bug (Lefitas aatiiiunalis, Shaw), x 100. (After Megnin.) 
The irritating swellings caused by Harvest Bugs are occasionally mistaken for the biles 
of midges or gnats. The Harvest " Bug " (Leptus aictumiialis, Shaw) is really a Mite, a 
minute Acarus, — the six-legged larva of a species of Trombidium ; it is possible that larvse 
belonging to more than one species are included under the same name. The annoyance is 
caused by these young forms burrowing into the skin, generally about the ankles and knees. 
Midges and gnats more usually attack the exposed parts of the body, although the females of 
both families readily bite through thin clothing.
