Guide to the study of insects and a treatise on those injurious and beneficial to crops, for the use of colleges, farm-schools, and agriculturists . arrangement« of the groups of spiders given by me is very imperfect. Itherefore present the following classification of Dr. T. Thorell(On European Spiders. Part I, 1869-70) as the most satisfac-tory. While I have considered the Araneina as forming a sub- APPENDIX. 715 order of the order Arachnida, it will be noticed that Thorellregards the Araneiua as an order, dividing it into the sevensuborders and twenty-two families indicated below. The ar-rangement of these groups is like the branches of a tree, andthis represents well the relations of the groups of articulates,as well as other sub-kingdoms. As Thorell remarks : Asregards the larger groups of spiders, the suborders and thefamilies, the reasons for the order of arrangement we havechosen will, we hope, easilj^ be seen if one casts ones eye onthe accompanying diagram, which gives a view of the con-nection founded on real affinity, which the families of thespiders adopted by us, according to our opinion, have to eachother.
