centre ; the exterior line consists of fliint white dots on the nervules, and 

 its course is marked by the slightest possible change of color between the 

 median and subterminal spaces ; the ante-apical white dots are very- 

 distinct ; the subterminal line wanting, except at the costa, where several 

 linear white shades show its place. Posterior wings yellowish white, with 

 a broad fuscous terminal border ; beneath the anterior wings are gr^iy, 

 with traces of an exterior line ; the apical, costal aud terminal regions 

 deeply suffused with carneous. Posterior wings whitish, with the fringe 

 yellow ; the costal and apical })ortions of the wings carneous. Hab.

In a recent paper, ]\Ir. Grote refers Cerainica to Tacniocampa, being 

 then only acquainted with Cerainica picta Harr. The discovery of this 

 species, which agrees perfectly in structural characters with picta, confirms 

 my previous o})inion that tlie genus should be recognized. The characters 

 which separate it from Tacniocanipa are not very striking, but they can be 

 readily appreciated, and the habits and markings of the two species are 

 very different from any of the Taeuiocanipas. Rubefacta approaches to 

 the description of vindemiaUs Guen., but differs in the presence of the 

 orbicular and in other particulars. 



In a recent number of the Entomologist Mr. Grote described a 

 species under the title of Pcrigrap/ia normajii. In working on allied 

 genera, we have identified this form, but we are unable to see the propriety 

 of the generic reference. 



The following are the characters of Lederer's genus Pcrigrapha : 



Eyes hairy; tibiae unarmed; antennae pectinated in both sexes; 

 collar cut out and j^roduced in front into a sharp corner : thorax with an 

 angular projection on each side, and bearing behind the collar a lofty, 

 sharp-edged, longitudinal crest ; abdomen with a closely cut tuft on the 

 first segment. 



In the species under consideration the antennae in both sexes are 

 simi)le ; the collar is not produced into a sharp corner ; the thorax is 

 rounded, without angular projections on ^he sides. Behind the collar ther« 

 is simply a small, flat, furrowed tuft, instead of a lofty crest ; the abdomen 

 is untufted. 



Such being the generic charac:ters of iiorniani, we remove it from 

 Perigrapha and refer it to a separate section of Tacnioeavipa, as it agrees 

 with the typical species of that genus, except in the possession of a slight 

 prothoracic tuft. The known species will now stand as follows
