CATOCAI>A AHOLIBAH. 73 



wliioh ivrc open aud clear from costa to interior margin, and wliicli are also orange coloured between the median 

 and sub-basal, and the latter anil base, are points that are so distinctive as to preclude all idea of the identity 

 of onr species with either of its European allies alluded to. The fact of the red ou under side of primaries 

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

 other known C'ato"ala.

E.xpands 4 inches. 



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



Upper surface; |)rimaries pale grey ami white, more or less powdered with dark grey or blackish atoms, 

 (and hear 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 which is much narrower and 

 jMire white; reniform dark, and shape not well detiued ; sub-renilbrm joined by a line to, not formed by, a 

 sinus of the transverse posterior line; fringe white. 



vSecondaries scarlet of a lovely shade ; mesial band narrowed in the middle, and e.x tends almost to the 

 abdominal margin ; fringe white. 



Habitat. Yreka, Caliliiniia. 



A regal insect, exceeding in size all known .Vmerican species; the nniiiue type from which the annexed 

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

 abdomen, as I before stateil, is non est, but from general appearances I should suppose the example in (piestion 

 to be a ^\ 



One can but regiet (hat so little concerning this tine 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.
