ANCYLIS BIARCUANA (Stephens). 



None of our collections contain any typical specimens of hiarcuana^ 

 and Kearfott,^' is probably correct in his surmise that it does not 

 occur in our fauna, unless, as I suspect, hiarcuanxi is only a larger 

 variety of diminutana Haworth. In any case it should be dropped 

 from our lists, as hiarcuana Stephens is nomen nudum.
