14 THE LPIDOPTERIST 



A New Race of Catocala delilah Streckcr 



By Samuel E. Cassino 



CATOCALA DELILAH F. UTAHENSIS. 



In general appearance utahensis is much lighter 

 than delilah. Delilah is a rich. Van Dyke brown, in 

 some specimens a Roman sepia, while the general ef- 

 fect of utahensis is a bluish gray in the lighter portions 

 of the superiors. The t. a. and t. p. lines are com- 

 posed of black scales, but are not heavy and broad 

 as in delilah or desdemona. The whitish scales in 

 the apical patch of desdemona are bluish gray in 

 utahensis. The line of whitish scales near the sub- 

 terminal line in desdemona is only very faintly indi- 

 cated in utahenscs. The subterminal line is 

 barely indicated except by two black arrow points. 

 The scales of the median space are bluish gray in- 

 stead of the rich brown of delilah and desdemona. 

 The subterminal space or outer margin is darker, and 

 between this and the median region the scales are 

 lighter brown. A black spot on the costa above the 

 reniform and a smaller one a little nearer the apex. 

 Reniform not very distinctly marked; subreniform 

 distinctly marked. The space between the outer mar- 

 gin and the t. p. line and extending from the inner 

 margin half way to the costa is devoid of very distinct 

 maculation, but in desdemona this is not the case. 



The secondaries do not differ from desdemona ex- 

 cept that the mediam black band is somewhat nar- 

 rower. 



All the specimens I have seen from Utah belong to 

 this race, and are readily distinguished from those 

 taken in Arizona or Texas, by the lighter coloration.
