singular looking insect is distinguished generically by the peculiar shape of the wings, and the equally remarkable appearance of the caterpillar. Of the former the posterior edge of the primary pair is concave, and the apex is distinctly truncated; the same edge of the secondary wings has two long linear tails, the anal one shorter and curved outwards, the external long, obtuse at the extremity, and turned somewhat obliquely outwards. The caterpillar is naked, with four long fleshy filaments on the back, and two others projecting from the hinder part of the head; the chrysalis likewise with several projecting filaments.

The Marius butterfly is a native of Guiana and Brazil. The colour of the upper side is tawny, varying somewhat in the shade according to the sex,
