ence. Hiibner's name is the one that must be used for the concep- 

 tion above described, including those species in which the middle 

 femora of the male have the mass of specialized scales normally de- 

 veloped. The species referred to Phceocyma by Mr. Grote do not 

 belong there. 



Zale Hiibner is a still earlier name for almost the same conception, 

 structurally speaking, but this offers greater differences in certain 

 directions. 



Based on our species horrida, the more divergent thoracic tufts, 

 emphasized because discolorous, and the more conspicuous dorsal 

 tufts of the abdomen make the genus recognizable; but these differ- 

 ences are only of degree and scarcely greater than occur elsewhere 

 in the series of species. In the male the middle femora have no mass 

 of specialized scales, and as there is quite a little series of species that 

 agree in this character or lack of character, I propose to hold Zale 

 Hiibner in a subgeneric sense as applicable to those species of 

 Phceocyma in which the middle femora of the male are not in any 

 way modified. 



As they appeared in collections when I began, the species of 

 Homoptera were considerably mixed up, and except for a few of the 

 better marked species names were doubtful. Under calycanthata at 

 least three distinct species were masquerading and neither of them 

 was the form described by Smith and Abbot. Morrison's species 

 were rarely identified at all, and as a rule erroneously when any at- 

 tempt had been made to name them. Lunifera Hiibner and squam- 

 mularis Drury were not correctly identified, and as a whole the 

 straightening out of the synonymy was the first and not least inter- 

 esting portion of the task before me. 



My own material was in no better shape than any other, and for 

 some years I had refused to apply names to species of this genus ex- 

 cept in a tentative way. Some years ago Dr. R. Ottolengui had be- 

 gun the accumulation of material with the view of monographing the 

 species, but press of other work caused the abandonment of this 

 intention. He was good enough to turn all his specimens over to me, 

 and this furnished the greatest variety of species in any one col- 

 lect ion. 



From the U. S. National Museum I secured their entire North 

 American series through the courtesy of the Curator. Dr. L. (). 

 Howard, and this was rich in examples from Texas and some other 

 portions of the South and Southwest. Some material of Doctor 

 Dyar's collecting in the Kootenai district was interesting in this 

 connection, and was supplemented by a very nice series of examples 

 received from Mr. William J. Cockle through Dr. James Fletcher, 

 who also sent me a number of other examples for examination and 

 study.
