diagonal rows, tlic walls of irreaulai- lioi^lit, beiiiK imich elevated into roiuuU'd bosses 

 at the lines of jiineture. Microiivle rosette occiipyiiiir the whole floor of a pretty deep 

 iufiiiidibuliform cavity, the sides of which are abrupt. 



Caterpillar at birth. The only spociuiens I have seen being dead and dried bodies 

 extracted from ej;gs which did not hatch, I can only say that the caterpillars of this 

 genus when they lirst emerge re.semble those of Heodes in almost every particular, but 

 that the secondary warts of the infrastigraatal row are apparently absent. 



Chrysalis. Considerably more than twice as long as broad, the sides of the body 

 straight and parallel from one extremity of the wing to the other; behind the wings 

 the abdomen as viewed from above is elliptical, well rounded; in front of the wings 

 the body tapers rapidly and has an appressed rounded front, the basal wing prom- 

 inences being niarkeil only by the angle the front part of the body makes with 

 the wings. Viewed from tlie side, the Mat bottom has the anterior fourth raised at a 

 slight angle; the thorax is highest and nearly equal on the posterior third, in front of 

 it very broadly arched, sloping about equally downward and forward. .Abdomen very 

 broadly arched above, highest and very slightly higher than the thorax at the third and 

 fourth segments, the last four segments curving rapidly downward, the posterior point 

 being at the summit of the niuth segment, below which it curves forward slightly ; 

 the downward curve at the posterior is much more rapid than at the anterior end of 

 the body. Transversely the middle of the tliorax has a parabolic curve, well rounded 

 above; the abdomen is well arched, regularly rounded, consideraljly higher than a 

 semicircle. More than three-lifths of the tongue is exposed. Basal wing prominence 

 consisting of a broad, low, rounded, slight elevation which would be scarcely notice- 

 able but for the narrowing of the anterior part of the body. Body covered equally 

 with a very delicate tracery of lines, equally raised everywhere excepting at the points 

 of intersection where there are minute warts; they cross each other irregularly, form- 

 ing angular, moderately large cells ; within the cells is frequently seated a large wart 

 giving rise to a fungiform l)ristle, the basal three-fourths of the pedicel equal, mod- 

 erately stout, the apical fourth rapidly expanding to a shallow, greatly expanded, infun- 

 diljuliform disc, the horizontal edges of which are fringed with fleshy ciliate lobes. 

 Hoolilets of cremaster rather long and slender, the stem equal, straight on basal, 

 curved a little on apical half, the expanded portion transverse, three or four times 

 broader than the stem, curved strongly, over the apical margin nearly straight, the 

 sides strongly produced laterally and somewhat backward. 



This genus seems to have but a siugle form in America, confined to the 

 eastern side of the continent, tiiough better rej)resented in Europe where 

 its range is also more extended between the 37th and 56th parallels. 



The group comprises some of the larger Chrysophanidi. The wings of 

 the sexes differ in coloring, though, at least in the American species, but 

 little in form. The upper .surface is coppeiy brown, tliatof the fore wings 

 mostly fulvous in the female, broadly bordered with dark brown on tlie fore, 

 reddi,sli fulvous on the hind wing-s : and is furnished with transverse series 

 of dark spots, the repetition of those beneath and which are more distinct 

 on the fore wings of the female than of the male. Beneath, the fore wings 

 are fulvous, the hind wings silvery gray, bordered as above ; both 

 wings have a double, submarginal series of blackish spots and an extra- 

 mesial tortuous series ; all the spots on the wings are small and generally 

 round ; besides there is a dark bar at the end of the cell, and at equal dis- 

 tances between this and the base two straight and transverse series of spots. 



The insects are double brooded and probably winter in the egg state.
