16. atcrrima Grote, Can. Ent., 11, 199. California. 



Of these sixteen species I have not been able to carefully examine 

 Meadiana, the type of which is in Mr. Tepper's collection. It seemed to 

 me different from any of the others, although the specimen is not in fine 

 condition. O. aterrima is aberrant in color and appearance ; Behrcnsi is 

 allied to the European confusa ; atricollaris looks like a Homohadena, as 

 which it was originally described. The variety of Chandleri which I have 

 collected near Buffalo, and which is called riparia by Mr. Morrison, does 

 not differ by the hind wings, but may be recognized by the paler gray 

 primaries and the white marked subterminal line ; the terminal black 

 interspaceal dashes are also wanting. My single ( % ) Buffalo specimen 

 now before me is more aberrant from Chandleri than Mr. Morrison's type 

 of riparia, or another Buffalo specimen collected by Miss Walker, to 

 which I have alluded Bull. U. S. Geol. Surv. 3, 117. More material is 

 evidently needed to decide on the value of riparia, which is our only 

 Eastern example of the genus. 



Homohadena chorda, n. s. 



Fuscous gray. Front and palpi pale ; fore wings shaded with pale 

 gray over the median space inwardly obliquely, and beyond the posterior 

 line narrowly and irregularly. Half-line present. Anterior line rather 

 thick, arcuate, a little uneven. Reniform vague, small and pale. Pos- 

 terior line narrower than anterior, a little uneven, nearly straight, not as 

 much inflected as usual. Subterminal line preceded by a diffuse black 

 shading. Terminal space fuscous. Median shade indicated by a black
