THE CANADIAN ENTOMOLOGIST. 83 



The palpi are very short. The whole upper surface is a dull clay 

 colour, paler than Packardata. Abdomen with very conspicuous black 

 band on second segment, and small black dorsal tufts on other segments. 

 The markings on the fore wings as in Packardata^ but the discals are 

 large and round instead of linear, and the dark spot on the costa, whence 

 the extradiscal line proceeds, is further from the discal spot than it is in 

 that species. 



Hind wings as in Packardata, save tliat the discal spots are larger. 



Beneath as in Packardata, but with the same differences as noted 

 above. 



The short palpi will distinguish this species from fiimosa Hulst. 



Types : i. Catskill Mountains, lo, VIII, '99, Mr. R. F. Pearsall. 



2. Sherborn, Mass., 14, VI, 1900, Mr. L. W. Swett. 



The first named is in my collection, the second in that of Mr. Swett. 

 I have other specimens taken at Toronto, Ontario (Saunders), and Newark, 

 N. J. (Weidt). 



A NOTE ON MR. JACKSON'S SYNOPSIS OF THE GENUS 



PEMPHIGUS. 



BY G. W. KIRKALDY, HONOLULU, HAWAHAN ISLANDS. 



I have recently received a separate of this article, bearing no date, 

 but apparently published during 1908. 



As far as the part dealing specially with the Aphidse is concerned, the 

 contribution seems to be admirable, but the writer displays a lack of 

 knowledge of Hemipterous literature and of the Hemiptera, as soon as he 

 embarks upon speculation on the " derivation of the genus." 



Basing my researches on those of Hansen, I have recently divided* 

 the Auchenorrhyncha into two superfamilies, Cicadoidea and Fulgoroidea, 

 fully discussing them. If, as Mr. Jackson asserts, the " Fulgoridfe do not 

 secrete a waxy or flocculent material from abdominal glands, where is this 

 material secreted from in that group ? The interposition, moreover, of the 

 Fulgoroidea between the Cercopidae and the Membracidse is an old 

 Fieberian misconception, faithfully followed by all subsequent authors 

 except Hansen and myself; it is not in the least warranted by the struc- 

 tures or habits of the groups in question.
