_Butterfly._--Black on the upper side of the wings, shading into reddish-brown on the basal area. The fore wings are spotted on the median and limbal areas with white, and the hind wings are adorned by a conspicuous median band of small white spots. On the under side the fore wings are fulvous at the base, broadly dark brown beyond the middle. The light spots of the upper side reappear on the lower side. The hind wings on the under side are marbled wood-brown on the basal area and the inner margin, darker brown externally. The white macular band of the upper side reappears on this side, but less distinct than above. Expanse, ♂, 1.25-1.50 inch; ♀, 1.60-1.75 inch. _Early Stages._--For the only account of the life-history of this species the reader is referred to the "Canadian Entomologist," vol. xi, p. 127, where the indefatigable Edwards gives us an interesting account of his original observations. This insect ranges from Texas into Mexico. It has been confounded by some with a closely allied insect, =Eresia ianthe=, Fabricius, and to show the difference we have given in Plate XVIII, Fig. 12, a representation of that species, by means of which the reader will be enabled to mark the difference on the upper surfaces of the two species. (3) =Eresia punctata=, Edwards, Plate XVII, Fig. 39, ♂ (The Dotted Eresia). _Butterfly._--A lengthy description of this little species is scarcely necessary, as the figure in the plate will suffice for its accurate determination. Nothing is known of its early stages. Expanse, 1.10 inch. It is found in New Mexico, Texas, Arizona, and Mexico. It has been recently declared to be identical with _E. tulcis_, Bates, an opinion I am not quite prepared to accept, but which, if correct, will force us, according to the law of priority, to substitute the name given by Bates for that given by Edwards. Genus SYNCHLOË, Boisduval (The Patched Butterflies) _Butterfly._--Medium-sized or small butterflies, rather gaily colored, although the species found in the United States are not very brilliant. They may be distinguished structurally from the butterflies of the two preceding genera not only by their larger size and the spindle-formed third article of the palpi, which in the genera _Eresia_ and _Phyciodes_ is thin and pointed like a needle, but also by the fact that the lower discocellular vein of the fore wings is generally quite straight and not bowed or angled as in the before-mentioned genera. [Illustration FIG. 94.--Neuration of the genus _Synchloë_, enlarged.] _Egg._--Similar in appearance to the eggs of the genus _Phyciodes_: obovoid, truncated, and slightly depressed at top, rounded at the bottom; the lower three fifths with shallow depressions; the upper part with about twenty-four light blunt-edged ribs. The eggs are laid in clusters upon the leaves of _Helianthus_.
