This tiger moth species was described in the year 1864.

Its range of distribution seems to have always been quite small (ca. 100 to 250 km²) and stretched over parts of New Jersey and Pennsylvania in the USA. Obviously this moth lived in grasslands there and flew in two generations, of which the first one appeared from May to June, and the second one in August.

The species was last seen sometimes in the 1960s and it is now very probably extinct.
