The color and tlie extent of the markinos in this species is subject to 

 great variation; ordinarily the front, inner margin of the cheeks, a part at 

 least of the pectoral pieces, and a spot or ring near the apex of the femora 

 .are fuscous or black. Dark examples have the disc of the discal and anti- 

 apical areoles, the base of the clavus and a spot before its apex whitish hya- 

 line. In pale examples the elytra are subhyaline with two transverse fulvous 

 or brown bands, more or less strongly indicated. Thus far the females. 

 The males are of a uniform dark brown or fuscous shade, with the vertex, a 

 transverse broad band on the front basally, and the the venter, soiled yellow; 

 the legs pale yellow, and a space on the commissural nervure near its apex 

 and sometimes another on its base whitish. In both sexes the face is less 

 convex than mfencstmtus and its allies and the vertex is consequently shorter; 

 the pronotum is transversely rugosely punctured, the anterior margin slightly 

 calloused and behind the eye obscurely pitted and the scutellum is frequently 

 tinged with ferruginous. The last ventral segment of the female is rather 

 short and bilobate, or waved on its hind margin. 



This is our most abundant species in western New York. I 

 have taken it in the vicinity of Buffalo, from June to August, and at 

 " Rock City" near Salamanca, N. Y., Aug. 2, 1889, at an elevation 

 of 1677 feet. Mr. Kilman has kindly sent me examples taken at 

 Ridgeway, Ont., and I am indebted to Mr. W. J. Palmer, Jr., for 

 several examples taken on Mt. Balsam, N. C. From Mr. Uhler I 

 have received specimens labeled Grimsby (Ont. ?), Connecticut and 

 Maryland, one of which is a typical example of nigrinasi rccei\'ed 

 by Mr. Uhler direct from Dr. Fitch. 



Although quite variable, this species can be readily distinguished 

 by the form of the' last ventral segment of the female, the blackish 

 front, and usually by the markings on the elytra. It lives on the 

 blue beech {Carpvius aiiicricamts). 



ABSCHIEDSWORTE. 



With this notice, my editorial work on Entomologica Ameri- 

 cana ceases. The business affairs of the journal have been, and 

 are such as to demand a constant personal attention, which I cannot 

 give. I have therefore concluded to relieve myself of possible 

 charges of neglect, and sometime since sent in my resignation to 

 the Society in such terms as to leave them no alternative but accep- 

 tance. 



It is with feelings of regret that I take leave of those to whom 

 I have written so often, and I take this occasion to thank most 

 heartily those who, by their aid and sympathy, have enabled me to 

 attain such measure of success for the journal as has been its lot. 



John B. Smith.
