We note, from the Proceedings of the 

 London Entomological Society, Nov. 5th, 

 that the Oxford Commissioners propose to 

 unite the Chair of Entomology founded by 

 the late Rev. F. W. Hope and honored by 

 the veteran entomologist Westwood, with a 

 Readership in Invertebrate Zoology. It 

 seems that the widow of Mr. Hope, before 

 her death, protested against the change as 

 opposed to the spirit of the bequests and 

 the clause of the deed under which the 

 Professorship was held. We sincerely hope, 

 with Mr. McLachlan, that the chair may 

 continue to be held by an entomologist, as 

 a guarantee that the extensive collections 

 will be properly cared for and appreciated, 

 and made to subserve the purposes in- 

 tended by the testator. 



Resistance of American Vines to 

 Phylloxera. — The vice-president of the 

 Horticultural and Botanical Society of He- 

 rault, M. de Lunaret, draws attention in a 

 recent number of the Messagcr du Midi, 

 to the fact that a downy, white-wooded 

 Riparia which was planted in 1S68, in 

 ground near Montpellier owned by a M. 

 Batigne, is still perfectly healthy, while all 

 the neighboring vines are dead or dying. 



The 17-YEAR Cicada in Iowa. — The 

 data furnished by Prof. Bessey are inter- 

 esting as more clearly defining the western 

 and northern limits of our brood XIII 

 (1878), which limits were previously un- 

 known ; also as showing more clearly than 

 was hitherto known the western limits of 

 our brood V (187 1). There can be little 

 question, we think, that the limits of this 

 brood may be extended throughout the re- 

 gion shown by the dotted lines and that 

 the discrepancy of a year or two in some 

 of the locations reported, may be accounted 

 for by accelerated or retarded develop- 

 ment. It is very difficult to say whether 

 or not the records for the extreme south- 

 western counties indicate similarly retarded 

 appearances of the more extended brood 

 XIII, or whether they represent our brood 

 XIV — that for 1862-1879 ; but as we have 

 given good reasons in the report already 

 cited by Prof. Bessey for considering these 

 two broods distinct, we think they should 

 also be kept distinct in the State of Iowa. 

 This conclusion is confirmed by data re- 

 ceived subsequent to the preparation of 

 Prof. Bessey's paper. The Cicadas were 

 very thick in northwestern Missouri and 

 also very abundant in Taylor and Adams 

 counties in Iowa. We have prepared a 

 map with a view of embodying the infor- 

 mation communicated by Prof. Bessey, and 

 which gives our own idea founded upon 

 his data of the distribution of the three 

 broods in question. By comparing this 

 distribution of the Cicada with the distri- 

 bution of timber, as shown in Plate i of 

 the Iowa AVeather Report for 1878 by Dr. 

 Hinrichs, it becomes obvious that there is 

 a relation between the two, namely that the 

 I most extended brood (XIII) occurs in the
