OF WASHINGTON. 319 



lighter and yellowish at base; fringe yellow. Beneath brownish yellow; 

 central portion of the anterior wings blackish ; discal dots distinct. 

 Expanse. 1.48 inches = 37 mm. 



Habitat. Hoboken, New Jersey. 



The above is the essential part of Mr. Morrison's original de 

 scription, and it applies fairly well to the small series of female 

 specimens that I have before me. 



Mr. Grote describes the male as follows: " Fore wings rich 

 reddish brown, the veins nearly black ; they might be called 

 purplish black or brown. The interspaces have a paler, some 

 what yellowish tint. No lines and no discal spots. Hind wings 

 reddish brown, a little paler than primaries, and paler at base. 

 Body duller and lighter brown. Beneath without marks, paler ; 

 disc of primaries a little blackish." 



This description is equally characteristic for both sexes, and the 

 absence of all trace of transverse posterior line is characteristic. 



The specimens before me range from 38 to 40 mm., = 1.52- 

 1.60 inches ; but the cf is smaller. I have seen only the example 

 from Kittery Point, Maine, from the Thaxter collection. 



In the series at hand are examples from Iowa City, Iowa, July 

 27 (Wickham) ; Brockport, N. Y. (Bruce) ; Wisconsin ; Louisi 

 ana ; Pittsburgh, N. Y. (C. F. Hudson). 



The range indicated by these localities is great enough to fur 

 nish more specimens than appear in collections ; but nothing 

 seems to be known of the early stages. 



The frontal protuberance is characteristic in appearance ; 

 shorter than the others, the tip notched, the lateral margins 

 toothed, with ridges extending from these teeth toward the cen 

 tral carina. From the side the appearance is equally character 

 istic, forming a downward angle toward the base. The figures 

 on Plate V will give a better idea of these structures than words of 

 mine can do. The lateral pieces of the female are not so defi 

 nitely bent as they are in the other species, but are rather curved 

 upwar<^ toward the broad overhanging anal lobes. The tip is 

 finely serrated and is notched toward its inner angle, making the 

 entire structure distinctive and clearly different from that found 

 in any of the other species. 



Finally, it might be suggested that collections need ^iot remain 

 so poorly supplied with species of this genus. They are not 

 really rare, but rather retiring in habit. They do not come to 

 sugar because the tongue is probably not functional ; they fly to 

 light, because we know that specimens have been so taken ; but 

 they are not greatly attracted by it and the captures are acciden 

 tal. Throughout the summer larvae may be found in Typha 

 (cat-tails) and perhaps in other plants growing in similar locali 

 ties. Careful investigation should discover the local breeding 

 places, and after that the matter should be easy.
