JOURNAL Jlf JBork Qntoraologiral ]Soriptg. \^oL IX. SEPTEMBER, 1901. No. 3. DESCRIPTIONS OF NEW TIPULID^E. By R. W. Doane. In my first article on North American Tipulidae (JouR. N. Y. Ent. Soc, Vol. VIII, No. 3) a number of mistakes occurred which were corrected in some of the separates sent out by me. It may be well to note these corrections here. Dicranoptycha borealis, should read Lim-nobia borealis ; Cryptolahis bisuuiatis should read Cryptolabis bisiiuiata ; LunnopJiila flavapila should read Lininophila flavipila ; Phyllolabis obscuris should read Phyllolabis obscitra ; Amalopis disphana should read Amalopis diaphana ; the reference to the plate after Polyangaiis maculatiis should read PI. VIII, Fig. 20, instead of PI. VII, Fig, 20. I am under obligations to Prof. J. M. Aldrich, Univ. of Idaho ; Prof. Trevor Kincaid, Univ. of Wash.; Dr. L. O. Howard, U. S. Entomologist and Curator of Insects for the National Museum, for large series of Tipulidas from their respective collections ; also to Prof. V. L. Kellogg, Stanford University ; Prof. Jas. Hines, Univ. of Ohio ; Mr. G. Chagnon, Montreal, and to others for smaller valuable series ; also to those having charge of the insect collections in the National Museum and in the Museum of Comparative Zoology in Cambridge for the privilege of studying the Tipulidte in these collections.
