first four joints with much black above; mesothorax black, with two 

 red marks ; varying to red with a broad black median band ; scutellum 

 red, prominent; postscutellum black marked with red, or red; meta- 

 thorax black, with two red spots in the enclosure; legs red, the femora 

 more or less blackened basally; wings strongly dusky at apex; stigma 

 ferruginous, nervures ferruginous to fuscous. I first received a speci- 

 men (Lehigh Gap) from Mr. Viereck, and placed it as a variety of 

 N. perplexa. A second example (Ithaca) appears to show that it is a 

 distinct species, not very close to perplexa. In my table of Gnathias 

 (Proc. Phila. Acad., 1903, p. 595) it runs to N. physura Ckll., from 

 Nevada. It is in all respects very close to physura, but a little larger, 

 with different lateral face-marks, and with the apical plate of abdomen 

 strongly notched. It is possible that it is a variety of N. bella, in which 

 the male has taken on much of the female coloration. The b. n., as 

 usual in Gnathias, goes a long distance basad of the t. m. ; the second 

 s. m. is ordinary. The venter of the abdomen is red suffused with 

 black; the base of the first dorsal segment is black. The pleura is 

 marked with red, varying to nearly all red. 



Ithaca, New York (Nathan Banks) ; Lehigh Gap, Pa., June

 the type. 



ADDITIONS TO THE LIST OF NORTH AMERICAN 



GEOMETRID^:, WITH NOTES ON SOME 



DESCRIBED SPECIES. 



[Lepidoptera.] 

 By JOHN A. GROSSBECK. 



The following embraces some of the species contained in 

 an interesting lot of Geometridse received from Dr. Harrison 

 G. Dyar for identification. In the case of Enphenolia palli- 

 m edia, n. sp., the main material came to me from Dr. Henry 

 Skinner, of the Academy of Natural Sciences, Philadelphia, 

 some time previous to the receipt of the specimens from the 

 National Museum. Most of the material came originally 

 from Dr. William Barnes, but all the types, except a few 

 which are retained in the author's collection, have been de- 

 posited in the National Museum. 



Hydriomena manzanita Taylor. 



Two specimens labelled Middle California. They are rather, 

 abraded and the ornamentation is so obscure that a different 

 species is suggested ; but a comparison with fresh examples
