BARNES AND McDUNNOUGH: CATOCALA 43 



(PL xxxv, figs. 2 and 3) are just the reverse of this and the names should be interchanged. The variety Isabella is allied 

 to aholah but is grayer and lacks the black median patch and subapical dash. 



The latter two names are based on Texan material and possibly represent forms of a good geographical race, peculiar 

 to the Southern States. 



The typical form is found in the New England and northern Atlantic States, extending northward into Ontario and 

 Quebec. In the southern Atlantic and Gulf States it merges into aholah, which we have never seen from northern localities. 



Group XIX 



Egg (where known) similar to that of the preceding groups. Larva with filaments and a rather prominent dorsal 

 wart. Male claspers asymmetrical, apices rounded. 



The larvse are oak-feeders, with the exception of minuta which feeds on Glcditschia and which possibly may form a 

 group by itself as the male claspers show certain points of distinction. However, there is no doubt that considerable 

 relationship exists between minuta and micronympha and we prefer to retain the species in one group for the present.

This is a small species with very variable fore wings. The type form is dark brown with a distinct, broad, white, 

 subterminal line. The variety parvula (PI. IX, fig. 2) is grayish or yellowish on the costal half and deep brown along the 

 inner margin and on the outer margin to below the apex. The variety mellitula (Fig. 3) has the subbasal space and the 

 whole of the median space yellow, the remaining parts being brown. There are numerous intergrading forms. 



The species is wide-spread throughout the eastern half of the United States, probably occurring wherever Gleditschia 

 grows; it is common in the central Plain States.

This species shows extraordinary variability in the coloration of the primaries; when more is known about the species 

 it may be found that there are several geographical races, but for the present we must treat them as mere forms or color 

 phases. The typical form is that with chestnut-brown primaries (PL IX, fig. 22); it is apparently most typical in the 

 South, all of our Floridan specimens being of this form. Fratercula Grote and Robinson is the pale olive-green form with 

 the markings of varied intensity (Fig. 25) ; if necessary, this name may be applied to the northern Atlantic States form, 

 the type material being from New York and Rhode Island; helene, jacquenetta, and timandra all seem to have been applied 

 to slight variants of this form and the names are scarcely worth retaining; it is possible, however, that timandra, based on 

 Texan material, may prove to have racial characteristics when more material is available. Holland's figure under 

 jacquenetta (PI. xxxv, fig. 5) is not typical; it is better referred to the type form. Atarah Strecker (as based on the male
