Iiruniuit the fore wings are suflused with reddish brown, and there is a distinct reddishbrown patch beyond tiie discal mark, with less white in the nsuallywhite oblique snbapical patch. lu var. trouvelotii, a large female expanding d-jmm., there is an olive tinge to the fore wings,but within the inner line are three brown patches, while the middle of the wing is clear olive-gray;beyond the discal mark the wing is tawny-brown. It is near the normal H. obliqna, but muchlarger, and olive-gray instead of brownish gray, rendering the markings more distinct; the hindwings are smoky Fig. 85.—Early stages of Hcterocampa oblirjtta ami H. guttii-itta.—l.
