HEMIFTEKA— UOMOFTEKA— FULGOKINA. 281 



APHANA Burmeister. 



To this genus are provisionally referred a couple of species which 

 belong in this neighborhood, but probably not together. No other extinct 

 species have been referred to this group, which is essentially subtropical.

A single finely preserved specimen, giving the upper surface of the 

 body, the displaced tegraina of one side, and a part of tlie middle leg of the 

 opposite side, is referred provisionally to Aphana. It plainly belongs to 

 the true Fulgorina, and seems to agree better with Aphana than with any 

 other genus concerning which information is at hand, but it is much smaller 

 than the species of Aphana (as it is larger than those of Poeocera), and 

 differs from it in the structure of the head and the brevity of the tegmina. 

 The head is small, being scarcely more than one-third the width of the 

 body, the eyes not prominent, the front scarcely angulated, and the vertex 

 of about equal length and breadth ; it is marked above with two longitudi- 

 nal blackish stripes, and the thorax with a median, and, on either side, a 

 broad, lateral, black stripe, all of them bordered by paler parts and the 

 median marked with a median pale line. The front of the thorax is strongly 

 and regularly convex, and the posterior border of the mesonotum is rect- 

 a"sgular. The tegmina are about three times as long as broad, with nearly 

 parallel borders, the tip roundly pointed ; the apical fifth is filled with fine, 

 closely pai'allel, longitudinal veinlets, extending from the tip of the radial 

 vein to the inner border, forming an area of equal width throughout. The 

 radial vein is parallel to the costa throughout. The ulnar veins originate 

 almost exactly as in Acrajphia, but the upper one does not fork before the 

 middle of the wing, when it sends downward a single shoot, while the lower 

 forks almost immediately, and again emits a vein beyond the middle of the 

 wing. The wing itself is apparently diaplmnous, but is mottled lightly with 

 faint fuliginous along the costal border, and more hgavily, but irregularly, 

 with dark fuscous on the basal half of the wing, especially next the extreme 

 base, and in a rather broad and straight but irregularly margined and 

 oblique band, crossing the wing from just below the sutural angle equally
