Duges valuable papers on the classification of the Aearidae, to Avhich we have already had so oftento refer, gave an impulse to their study, which led to fresh dis-coveries ; and M. Turpin observed in the nail-galls of the lime leaf aquantity of very minute, semi-transparent, fleshy mites, of a new andhitherto unknown form,—a narrow creature with two pairs of smalllegs at its head, and some kind of sucker apparatus at its tail, on. 28 FOREST ENTOMOLOGY. which it rests and raises itself, swaying about its body. He regardedit as a species of Sarcoptes.* Here is an account of the first true conception of the family Eri-ophyidae, and the species under consideration is in consequence a mostimportant one.

Thehedges are generally well stocked with the field maple (Acer cara- pestre). The upper surface of theleaves of the field maple are oftencovered with small galls, and acareful examination will show thatthere are two sorts,—a larger anda smaller variety. The larger —which are, as a rule, rathersparsely distributed on the leaves,and generally on the midrib andveins—are the galls of E. macro-chelus. These galls are very vari-able in many ways, both as regardscolour and structure. They maybe solitary or gregarious, single orcoalesced, glabr
