Catocala fausttna Strk. form rubra f. nov. 



By Samuel E. Cassino 



In the type form of fausitina there are no traces of 

 red and zillah is readily distinguished hy the red 

 suffused primaries. It is described by Strecker as 

 follows : — "Zillah is distinguished from the common 

 form by the upper surface of primaries being suf- 

 fused with rather scattered rust red atoms, especially 

 about the reniform and sub-reniform and along the 

 transverse posterior lines and thence to sub-mar?inal 

 lines." 



No mention is made in this description of a heavy 

 dark shade or dash exteding from the base, parallel 

 with the inner margin, to a point just above the inner 

 angle. An examination of the type reveals the pres- 

 ence of this dark shade. Although the description 

 does not mention this dash, which is a prominent feat- 

 ure, it would seem best to consider it as characteristic 

 of the form zillah. The red form of zillah, in which 

 the dash or shade does not occur should be designated 

 by a form name, and rubra is suggested as appropriate. 



In the form, rubra, the reniform, sub-reniform and 

 transverse lines, as well as the space just outside the 

 t. p. line, are quite heavily suffused with brick-red 

 scales. The specimen adopted as type is a ci" having
