48 ENTOMOLOGICAL NEWS. [February, 



Mr. Chittenden presented by title a paper on " Food-habits of Chryso- 

 melidse." 



Mr. Schwarz called attention to a statement by Dr. M. Busgen (in the 

 latter's work on the honey-dew of Aphids) to the effect that the honey- 

 dew is not secreted from the nectaries as hitherto supposed, but ejected 

 from the anus. He also referred to an interesting work recently pub- 

 lished by C. A. Piepers on migratory movements of butterflies on the 

 island of Java, and gave a brief resume" of the author's explanation of 

 these phenomena which are comparable to the nuptial flight observed in 

 other insects. 



January 7, 1892. Election of officers for 1892 resulted as follows : 



President, C. V. Riley; First Vice-President, C. L. Marlatt; Second 

 Vice-President, Wm. H. Ashmead; Treasurer, E. A. Schwarz; Recording 

 Secretary, Nathan Banks; Additional members of Executive Committee, 

 Wm. H. Fox, Geo. Marx and B. E. Fernow. 



The retiring President, Dr. Marx, delivered his annual address on "An 

 Introduction to a Monograph of the American Ticks (Ixodidae)." In an 

 introductory chapter the author drew attention to the absence of mono- 

 graphic works which would attract and facilitate the work of the begin- 

 ners in Arachno ogical studies, and also the inherent difficulties in the 

 obscurity of many of the classificatory characters. He pointed out the 

 nature and extent of the work already done in the various groups of 

 Arachnida and followed with a reference to the bibliography of the writings 

 both foreign and American on the ticks of this country. 



A full chapter on the morphology of ticks followed, and also extended 

 notes on the biology of these parasites in which personal observations 

 were recounted, showing that ticks are not necessarily parasitic on warm- 

 blooded animals, but may reach full growth, and in fact complete the 

 cycle of their existence on a strictly vegetable diet, and also that ticks, 

 after being gorged with blood, may revert to vegetable food. The address 

 was discussed by various members.
