It may be interesting, also, to note that along with the gall-flies, 

 inquilines and parasites, there were bred various Cecidomyids, saw- 

 flies, cuckoo-flies, ichneumons, braconids and ants. 



MISCELLANEOUS NOTES AND DESCRIPTIONS OF 

 NORTH AMERICAN GEOMETRID^. 



By John A. Grossbeck, 

 New York, N. Y. 



Petrophora rubrosuffusa, new species. 



Expanse, 24-27 mm. Palpi and front deep brown, vertex whitish or reddish, 

 sometimes composed of a combination of these colors. Thorax and abdomen 

 soiled yellowish, the collar and patagia of the former marked with black, all 

 wings soiled whitish suffused with a delicate shade of grayish-brown, and, on 

 the costal area of the primaries with pink most pronounced toward the apex. 

 Intradiscal line of primaries absent or marked on the costa one-fourth out by 

 a white, squarish spot. Median line similarly marked on the costa slightly 

 inward of the middle. Extradiscal line whitish, rather broad, distinct on 

 anterior half of wing, obscure or absent on posterior half ; extends from one 

 third in on costa in an even outward curve to M3, then, forming an acute angle, 

 runs in an even inward curve to inner margin. Discal spots absent. Beneath, 

 pinkish-ash except on posterior half of primaries where it is soiled whitish 

 tinged with smoky toward the basal portion. Primaries with anterior part of 

 extradiscal line reflected and marked inwardly by a blackish shade. Secondaries 

 with an elongate black discal mark divided by a clear white dot. A brown 

 extradiscal line on the outer fourth of the wing running subparallel to the 

 outer margin may be traced from the inner margin to vein Cm; or M^ and from 

 here on is marked on the veins by more or less distinct dashes. 



Types. — Three males from Dr. Barnes, one cotype of which is 

 deposited in the American Museum of Natural History. 



Habitat. — White Alts, and Palmerlee, Arizona. 



From above this species very closely resembles Stamnodcs ddicata, 

 but besides having pectinated antennae in the male, the present species 

 is very different in design beneath. Structurally and in maculation it 

 is more nearly related to Petrophora voluccr and from this species 

 may be distinguished by its somewhat shorter and broader wings and 

 by its deeper coloring.
