DESCRIPTIONS OF LEPIDOPTERA FROM ALABAMA. 



BY AUG. R. GROTE, DEMOPOL1S, ALA. 



Cataclysta Robinsonii Grote. $ °. I refer this species to Le- 

 derers Section C. : veins 8 and 5 of the secondaries present. Primaries 

 bright golden brown. The median whitish grey space is tolerably narrow 

 and well defined ; inwardly bounded by the outwardly arcuate white 

 transverse anterior line ; outwardly by the white transverse posterior line 

 which is angulated on the m. nervules. Both the lines are a little uneven. 

 From the distinct and regularly arcuate white transverse anterior line to 

 the base of the wing, the surface is entirely golden brown. On the gray 

 median space there is a blackish stain at the extremity of the discal cell, 

 preceded and defined inwardly by a C-shaped white shade line. Outside 

 the transverse posterior line, the wing is terminally dark golden brown, 

 but becomes dark greyish over the median nervules opposite the angula- 

 tion of the line ; the brown colour obtaining again, over the internal 

 angle. A distinct white sub-apical rounded line (following the shape of 

 the external margin, and allowing, at the apex, the brown scales to appear 

 beyond it), is shortly discontinued. Fringes dark grey. Secondaries pale, 

 powdered with black scales, and these are aggregated in a little cluster 

 before the internal margin. Before the external margin the wing is lin- 

 early free from the dark scales, and beyond, on the margin, lies a double 

 series of velvety-black dots, between which, and alternating with them, is 

 a row of brilliant scales, the whole not very conspicuous. Beneath, the 

 hind wings are paler, with an incomplete median band ; the marginal 

 series of black and scintellate dots is repeated, but the black dots are 

 single. The fore wings are dark greyish beneath, the two median lines 

 dark, and not very distinct, the median space, posteriorly, is stained with 

 blackish, and the white semi-circular mark of the upper surface is dis- 

 tinctly repeated. Apically, the wing is shaded with brown, and here the 

 terminal white line is distinctly repeated. Exp. 18-19 m. m. Coll. Pea- 

 body Academy of Science, & C. T. Robinson. 



I took a pair of this pretty species in July near Demopolis. 

 Erratum. — The top line on page 126 of this volume should be 

 placed in the same position on page 125.
