The eggs are very enrious, lieing nearly glolinlar, covered with high walled, hexagonal cells, from each angle of whicii arises a rather long, i<titt', tapering filament. According to Danhe and (iiirtner, those of the European genera Linienitis and Nymphalis are similar. The larvae are e.\ceedingly grotescpie in appearance and present at the same time a very threatening aspect ; the heail is sin'nionnted hy a jiair of warty glol)idar tubercles, and the fore part of the body is considerably hunched and tnbercnlated, bearing, on the middle thoracic segment, a long, stout, clubbed horn, bristling witii short iiarbs ; the hinder segments of the abdomen are also hunched and tnbercnlated, and the whole body is so strangely and irregidarly mottled with cream color and various shades of green as to add greatly to the fantastic eHect. They may be distinguished i'rom the caterpillars of Najas by the contraction of the first thoracic seg- ment, the absence of profusely distributed minute papillae over the body, and the reduction of all the tubercles of the thii-d thoracic and second, sev- enth and eighth abdominal segments, the latter less marked in the; southern 1). eros than in our other sjtecics. The caterpillars of astyanax and archip])U8 resemble each other most sti'ikingly, and pi'obably in theii- earlier stages it would l)e almost imjiossi- ble to distinguish them.
