216 THE CANADIAN ENTOMOLOGIST. 



Types, Yuma Co., Arizona, March. Cochise Co., Arizona. 



I am under great oWigaiions to Prof. J. B. Smith for more perfect 

 specimens of this interesting species than those I already possessed. I 

 am rather incHned to think this species may form the type of a new genus, 

 but prefer to place it here provisionally, leaving its final disposition to 

 someone more competent than myself to examine it structurally. 



Coccus luzena, n. sp. — Expanse, 24 mm. 



' Head, collar, patagia, thorax and fore wings evenly gray. Inner half 

 of fore wing quite thickly covered with transverse blackish strigse. In the 

 outer half these have a tendency to be more reticulated. A rather heavy 

 black band from middle of costa downward and outward, dividing into 

 two or three prongs jubt before reaching inner margin. Two similar 

 though less heavy lines leave costa between inception of median line and 

 apex. These unite and proceed as a single line for a short distance and 

 then divide into two or three branches just before reaching inner angle. 



Hind wings gray w.ith a somewhat reddish-brown tinge. Beneath 

 fore wings gray, somewhat reddish-brown centrally, hind wings gray, both 

 wings reticulated with black, the inception of these on costa of fore wings 

 being especially pronounced. Thorax gray, abdomen greasy, but appar- 

 ently gray. Tegs gray, tarsi banded with black. 



Type, I $ . Huachuca Mts.,. Arizona. 



ON THE SPECIFIC VALIDITY OF INCISALIA HENRICI. 



BY JOHN H. COOK, ALBANY, N. Y. 



For many years I have collected diurnal Lepidoptera in the neigh- 

 bourhood of Albany, N. Y., making a special study of established 

 varieties, sports, and minor vatieties within the sj^ecies. 



Among the Lyccenidce the forms which have proved of greatest 

 interest from this point of view are those embraced in the genus Incisalia; 

 I. irus in particular has afforded abundant material for investigation, and 

 long ago I was enabled to recognize several tendencies in the distribution 

 of colour over both the wings and body, whicii made it passible to 

 separate this species into groups or form-series. These variations 

 appeared in both sexes, and, as it then seemed, without any indication of 

 tendencies peculiar to either. As an illustration of the danger accom- 

 panying the untjualified acceptance of a generalization, I may state that, 

 after having satisfied myself with regard to the character of the discal 

 stigma of the male, I made use of this as a criterion of sex.
