CATOCALA AHOLAH. 97 



that towards the exterior margin does not so abruptly terminate, but somewhat gradually shades off ; sub- 

 reniform entirely disconnected from transverse ])()sterior line; sub-ferniinal line brownish; in the space 

 between the base and transverse anterior line is a kidney-shaped spot of the same greenish white and same size 

 as tile reni form ; this spot is not i)roininent, though easily discernible ; fringe concoloiirous with the ground 

 colour of wing. 



Secondaries bright yellow ; marginal band nioderately broad, interrupted before reaching the anal angle, 

 where it is replaced by a black s]iot ; mesial narrow, somewhat elbowed, and extends to the abdominal margin 

 and thence upwards towards the base; a very small, yellow apical spot; fringe white, greyish inwardly. 



Under surface yellow, darkest near bases, at costal and apical parts white or nearly so ; no sub-basal 

 band ; marginal and mesial bands blackish brown, very sharp and distinct ; fringes white, cut with black at 

 terminations of veins. 



Texas ; from Mr. J. Boll. 



A most beautiful species, whose nearest eastern ally is C. Formula, than which, however, it is larger and 

 much brighter in colour, and presents many |)oints of difference in ornamentation.

Since describing this most beautiful species on page 93, from a 9 taken in Indianapolis, I have received 

 other examples, c?9 taken by Mr. Boll in Texas. 



CATOCJALA ATARAH. n.,v. .-> ^ 



(PLATE XI, FIG. lU c?, 11 ¥•) 



Male. Expands 1§ inches. 



Head and thorax brownish grey ; abdomen brown. Beneath, pale greyish. 



Up])er surface ; primaries brown ; transverse anterior and posterior lines broad and dark ; reniform in- 

 distinct; sub-reniform pale and free from the transverse posterior line; the mesial area, between the reniform 

 and transverse anterior line, paler than any other part, the outer half, between this and the transverse posterior 

 line, is the darkest part of the wing. 



Secondaries yellow ; marginal band dee|>ly indented towards anal angle; mesial narrow, prolonged in an 

 acute angle above the indentation of marginal band, and extending almost to the abdominal margin, and from 

 thence upwards towards the base; a streak of dark colour extends from base to the indentation above the elbow 

 of mesial ; fringes yellow and brownish. 



Under surface yellow ; no sub-basal bands ; mesial and marginal bands blackish. 



Female. Same size and markings, but the superiors are brighter in colour ; the transverse anterior is 

 narrower and lined inwardly with whitish grey; reniform better defined; sub-reniform not so distinct; sub- 

 terminal line white and most conspicuous near and at the costa. 



Texas; from Mr. J. Boll. 



It is with some slight hesitation that I place these as sexes of the same species. As there were but two 

 examples taken, the material for study and comparison was, consequently, limited; I am inclined to think, 

 however, that future observation will verify my present decision, as the only difference is the narrower trans- 

 verse lines and brighter colour of the female.
