finely shagTcenod, also with minute, sparse, smooth granules and a 

 very few secondar}- hairs toward vertex; green, slightl}' shining, a 

 very obscure paler band up the anterior angles from ocelli to vertex 

 and a fainter one on occiput from base of vertical triangle; apices of 

 lobes slightly yellowish; jaws black; labrum furcate, brownish; 

 antennae mostly pale; ocelli brown shaded except the upper and lower 

 ones; width 7 mm. Bod}^ large, robust, smaller before; anal plates 

 large and thick; joint 12 enlarged dorsall}' with an enormous thick 

 club-like horn, studded thickly with cones, the end rounded, not 

 pointed. Segments 8-annulate, the ordinary granules minute, but the 

 sparse ones distinct and pale with rather long and distinct brown sec- 

 ondar}^ hairs, perfectly visible without a lens. Green, a dorsal vascular 

 line shading into purple, bordered with j^ellowish posteriorly (joints 

 6 to 10), the lateral obliques very faint dark shades, lighter edged, 

 except the one on joints 12-10, which is a very distinct, broad, white 

 line edged with dark green before. Horn olivaceous lilac above, the 

 studding cones pale ocherous with brown tips. The three anal plates 

 are rounded triangular, green, covered with large slightl}" elevated 

 yellowish brown granules, faintl}^ circled with yellow. Other abdom- 

 inal feet green, the claspers black; thoracic ones yellowish white, 

 streaked and spotted with black, with a few small whitish granules. 

 Spiracles large, dark brown, shading paler above and below, with a 

 central vertical white line. Later the horn l)ecame dark violet above, 

 the dorsal stripe violet, broad and distinct, narrowing anteriorly to 

 obsolescence. The larva entered ground and formed u cell in the 

 earth.

The ynviet J ^floridnni lacks the blackish bars that occur on thediscal 

 and submedian folds of the fore wings of the typical form. It occurs 

 exclusivel}" in southern Florida. The larva resembles that descri]:)ed 

 and figured b}- Sepp, but the food plants which I observed were dif- 

 ferent. Sepp states that his larva were found on guava {Pskllum 

 %>yriferurii)\ mine were found only on the wild species of Eugenia. 



The moth has been placed in the Arctiidte, and Sir George Hampson, 

 in his recent monograph of the Syntomida, omits the genus, thereby
