and subterminal patches also obsolete, the latter, when at all traceable, round 

 rather than barlike. Hind wing distinctly paler at base. 16 mm. 



July. Larva on Cornus. 



Northern New Jersey. New York : Ithaca. 



24. C. exoleta Zeller. Clay-color, with a more or less distinct oblique fuscous 

 shade resting on basal angle; powdery at edges; without definite boundary. A 

 contrasting round black dot at apex, twice as large as the usual apical dot, and 

 only preceded by very faint paired striae. 16 mm. 



June and July; late August. Larva reported from hazel and gooseberry. 

 Generally distributed and not rare. New York: Ithaca. 



ttttt Markings of usual Cymolomia pattern; basal area formed of a patch below R, 

 and a slender dark stripe in base of cell Sc, separated by a distinct pale line ; 

 costa pale 



25. C. tiliana Heinrich (Kearfott ms.). Ground blue-gray with a slight violet 

 tinge, flecked with brown, the markings slightly olivaceous brown and edged with 

 clay-color, exactly as in C. permundana. Median patch usually with costal por- 

 tion, including the long upper tooth, separated from the second tooth and dorsal 

 portion. Fringe of hind wing white. 18-20 mm. 



June and July. Larva on basswood. 



The basal patch in this species is sometimes as in C. permundana, but it is dis- 

 tinguished by the even and finely white-edged dorsal part of the median fascia, 

 normally contrastingly paler than the other markings. 



Northern New Jersey to Missouri. New York : Ithaca. 



26. C. ferruginana Riley. Bright ochre, with a slight olive tint; the ground a 

 little grayer, paler, and more powdery than the markings, which are crisply pale- 

 outlined. Median fascia broken into costal and median streaks and a dorsal patch, 

 the latter fused with the anal patch. 15 mm. 



Originally reported as bred from Hydrangea; but the type in the United States 

 National Museum is labelled " plum." 



New Jersey to Missouri. 



This form and the next two are very possibly mere color-varieties of a single 

 species. 



27. C. fagigemmeana Chambers. Like C. ferruginana, and with similar pattern. 

 Markings on basal half of wing light olive, including the dorsal half of the 

 median fascia and anal spot; costal part of fascia and apical spot light ochre, 

 contrasting. Ground grayish, also paler in the apical region. 



Larva a bud worm on beech. 

 Pennsylvania; southern Ohio; Kentucky. 



28. C. nitidana Clemens. Ground rose, strongly shot with violet; markings 

 bright tawny brown. Markings mostly normal; lower end of median band usually 

 separated and fused with anal patch to form a large M-shaped patch. Hind 

 wing of male with anal angle markedly lobed, though less so than in C. footiana. 



July. 



Pennsylvania and southern Ohio; doubtless widespread. 



29. C. nigrana Heinrich. Ground varying from light pinkish brown to dark 

 purple-gray, with dark chocolate brown to black-brown markings, clean-cut and 

 strongly contrasting. Markings normal, mostly as in permundana; anal patch 

 triangular, often fusing with lower end of the median fascia, which touches the 

 inner margin beyond, leaving a narrow triangular area of the ground color along 

 the inner margin beyond it. Dorsal third of wing frequently contrastingly darker. 

 Hind wing markedly paler toward base. 20 mm. 



July and August. 



Generally distributed. New York: Geneva, Ithaca.
