The best book about American spiders is "The Spider Book" by Professor J. H. FIG. 95.—Web of a grass spider, A galena sp. (Reduced.) TICKS AND MITES (ORDER ACARINA) From an economic standpoint the mites and ticks, consti- tuting the order Acarina, are by far the most important mem- bers of this class. The body is very compact, the cephalo- thorax and abdomen being closely fused. This character will serve to separate them from the spiders, the young of which might be mistaken for mites.

The young when first hatched have only six legs but after the first.
