early spring ; Mr. Swett mentions March for the Texan specimens ami 

 our specimen was taken in early April along with frigidata Wlk. 



In our Contributions \'ol. II, p. 204 we referred to some Colorado 

 specimens, identified for us by Mr. Swett as bistriolata, as being dis- 

 tinct from this species ; an examination of the $ Uncus of these 

 Colorado specimens shows however no point of difiference from that 

 of our Decatur specimen ; it would seem therefore that Mr. Swett was 

 correct and that we were in error in calling these a distinct species ; 

 they do, however, represent a distinct race characterized by the entire 

 lack of green shading, the deeper brown color of the antemedian band 

 and the paler color of the secondaries ; the basal and median areas of 

 primaries are also considerably suffused with light gray scaling. We 

 propose the name modestata for this race, our types being 2 ,J , 2 ? 

 from Glenwood Spgs., Colo, captured in April and May, one of the 9 

 Paratypes being in the American Museum Collection. 



Hydriomena chiricahuata Swett. (PI. \', Fig. 5). 



As previously stated the type must be limited to the 3 specimen 

 from the Chiricahua Mts., Ariz. The type of Uncus is distinctly that 

 of bistriolata, in fact, apart from the smaller size, which is only natural, 

 we can see no difiference in the structure of this organ in the two 

 species ; it may be, therefore, that chiricahuata is merely a small Arizona 

 race of the preceding species but for the present it may be kept separate 

 until more is known about its life history and time of appearance; 

 apart from the type we have seen three $ specimens from Palmerlee. 

 Ariz., all undated, and 2 9 's from Yavapai Co., Ariz. (July 2) and 

 Prescott, Ariz. (Sept. 9) which seem referable here; I $ and 2 9 's 

 are in the American Museum material ex Coll. Grossbeck. 



H\T)RiOMENA RUBER.\TA Freycr. (PI. V, Figs. 6-9; PI. IX, Figs. 6, 7). 



The species occurs quite commonly in the New England States 

 and extends Westward through Canada to the Rocky Mts. ; we have 

 series from Manitoba and Alberta which show, besides the typical 

 form as figured by Seitz (Macro. Pal. IV, PI. 10k) also the form 

 variegata Prout ; it is probably that the other European forms also 

 occur as noted by Mr. Swett (C. Ent. 47, p. 61). We have no record 

 of the occurrence of the species in British Columbia, although we have 

 a single 9 labelled Easton. Wash.
