38 CATACOLA UNIJUGA. 



Under surface, primaries white, with broad black marginal and median bands, sub-basal 

 band of paler color, and docs not extend to interior margin. 



Secondaries have inner two-thirds of same red as on upper surface, the costal third is 

 white ; black bands same as above, excepting that the mesial reaches in some examples quite 

 to the margin ; a discal hine connects with mesial band on its inner edge. 



Habitat. Canada, Xew England, Middle and Western States. 



This fine sj>ecies, which is rather rare, belongs to the group of which C. Xupta is the type. 



CATOCALA PARTA. Guenee. 



Spec. Gen, Vol. VIT, p. S4. 



( PLATE V, FIG. 10 ? ) 



^ 



Expands 3 inches. 



Thorax, above, grey ; abdomen ochraceous ; beneath, greyish white. 



Upper surface, primaries grey shaded with yellowish brown, the whole surface has a 

 smooth silky look, quite different from the squamose i^owdery appearance of C. Unijuga ; 

 the transverse lines, which are arranged much as in that species, are geminate, and as well as 

 all the other markings are very distinct and clear. The sub-rcniform is large and entirely 

 disconnected from the transverse posterior line ; between the sub-median vein and first median 

 veinlet is a dark longitudinal Hue or shade, extending from the transverse posterior line to 

 exterior margin ; interior to the reniform is a pale patch ; fringes grey. 



Secondaries bright red ; median band narrow and terminates in a jwint, two lines from 

 the abdominal margin. 



Under surface same as in C. Unijuga, except that the sub-basal band of primaries is as 

 dark in color as the others. 



Habitat. Canada, New England and Middle States. 



In many localities quite common ; the larva feeds on various species of Salix and the 

 imago appears middle or end of July. 



CATOCALA TERPLEXA. NOV. '^ VAR. 



(I'LATE V, FIG. 11 cf •) 



ExpaiBt 3| inches. 



Tliorax)^|l)ove, blueish grey, abdomen brownish yellow ; beneath, white. 



Upper surM^primarics dark blueish grey; transverse lines black and distinct as in C. 

 Parta. Two whi^fc^rs cross the wing, one formed by the intervening space between the 

 transverse posterior a^ sub-terminal linos, the other by the large sub-reniform and the space 

 adjoining it interior to the reniform ; sub-apical dash black ; fringes concolorous with the 

 ground of wing.
