CATOCALA AHOLIBAH. 7S 



whioh are open aad clear from costa to interior margin, and which are also orange coloured between the median 

 and sub-basal, and the latter and base, are points that are so distinctis'e as to preclude all idea of the identity 

 of our species with either of its European allies alluded lo. The fact of the red on under side of primaries 

 being of an entirely different tint from that of secondaries is very remarkable; I do not believe it exists in any 

 other known Cato-ala. 



March 1st, 1874.

Proc. Ent. Soc, Phil., Vol. II, p. 50.S, (1864). 

 (PLATE IX, KIG. 6, ? ?.) 



Expands 4 inches. 



Head and thorax light grey; abdomen is wanting in the single example so far known. 



Upj)er surface; primaries pale grey and white, more or less jwwdered with dark grey or blackish atoms,, 

 (and bear a superficial resemblance to those of the European C Fraxini*); transverse lines black; beyond 

 the transverse posterior line, a brown band, succeeded outwardly by another wiiich is much narrower and 

 pure white; rcnifbrm dark, and shape not well defined; sub-renitbrni joined by a line to, not formed by, a 

 sinus of the transverse posterior line; fringe wiiite. 



Se(«n(laries .scarlet of a lovely shade ; mesial itand narrowed in the middle, and extends almost to the 

 ibdominal margin ; fringe white. 



Habitat. Yreka, California. 



A regal in.scct, exceeding in size all known American si)ecies ; the unique type from which the annexed 

 figure was drawn is in the Museum of the Am. Ent. Soc. ; its sex can not be determined, as, unfortunately, the 

 abdomen, as I before stated, is non est, but from general appearances I should suppose the example in question 

 to be a +. 



One can hut regret that so little concerning this fine species is known ; the original description contains 

 no further remarks than ''from Yreka, California," and we can only hope that time, which "at last sets all 

 things even," will enable us to receive specimens, and learn more concerning this superb insect.

Expands 2 to 2^ inches. 



Head and body brown above, greyish white beneath. 



Upper surface ; primaries pale ash-coloured, a broad, longitudinal, rich deep brown space covers the lower 

 one-third of the wing to the interior margin ; a broad, suffused, sub-apical dash of the same colour; reniform 

 small, generally almost obsolete; snb-renifbrm open. 



Secondaries deep red ; mesial and marginal bands regular, and extending to abdominal margin ; fringe 

 white. 



Under surface ; ])rimaries, base black, between this and the median band the space is red, between the
