ON THE CORNICLES OF THE APHID^. 



BY J. R. DE LA TORRE BUENO, NEW YORK. 



Among the many interesting matters discussed at the New York 

 meeting of the Association of Economic Entomologists, the question of 

 the source of the so-called honey-dew of the Aphides was touched upon by 

 some of the members present, and doubts were freely expressed as to its 

 being ejected at the cornicles, although so stated in the majority of works. 

 By a curious coincidence, I received, from Professor .Geza von Horvath, 

 of Buda-Pesth, a separate of a paper he published, in 1905, on the matter, 

 (Sur les cornicules ou nectaires des Aphidien, C. R. 6me. Congr. intern, 

 de Zool.;, of which what follows is an abstract. 



The learned Hungarian briefly mentions the nature, position and 

 dimensions of the tubes, and then proceeds to review the opinions of 

 Reaumur, Bonnet, Linne, to whose great authority he attributes the prev-
