Lepidoptera of New York and Neighboring States 371 



rowly striped, and the other segments narrowly striped if at all. Tuft, when 

 perfect, bilobed, Albuna-like; largely black. Hind legs yellow, black between 

 spurs of tibiae. Fore wing normally with small hyaline areas in and beyond cell, 

 fully scaled below cell in many females, and always with the outer part of the 

 cell Cu fully scaled. Scaling of fore wing mixed black and yellow. Male usually 

 with more hyaline and black, and less yellow. Border of hind wing wider than 

 usual, with yellow and red scales. 15-22 mm. (lupini, washihgtonia, perplexa, 

 hemizonicB, impropria Henry Edwards). (H. 46:31 <$, 32 $.) 



Light specimens are very close to C. bassiformis var. sexfasciata, but differ in 

 that the stripe on the first segment is much weaker than on the second. Scitula 

 may be distinguished by the much narrower black bar at the end of the cell (it 

 is as wide as high in rutilans, and more than twice as high as wide in the scitula 

 group); ithacce may be recognized by the black hind legs. 



Larva in roots of Veronica, blackberry, raspberry, and strawberry; probably a 

 general feeder. 



Nova Scotia to New York and the Western States; doubtless also in interme- 

 diate localities in Canada. 



7. C. corni H. Edwards. Black, slightly marked with yellow; hind tibia with 

 a black patch; anal tuft contrasting, bright red, with a black center, often spread 

 fanlike. Fore wing with scaling black, border extending only a third way in toward 

 cell. 20 mm. 



Larva in small branches on silver and red maple, causing a gall-like swelling. 

 Massachusetts to Parry Sound, Ontario, and western Pennsylvania. New York: 

 Sharon Springs, Karner, Staten Island; Brooklyn and Newtown, Long Island. 



8. C. acerni Clemens. Head and body shading from light tawny to straw yellow 

 and light fuscous; anal tuft wholly light red, normally paler than in 0. corni. Fore 

 wing with border light yellow between veins (rarely with only a few yellow scales) 

 extending two-thirds way in to the large black discal bar ; hind wing also with discal 

 bar large. 25 mm. (acericolum Germar). 



Larva boring under bark of the larger branches and trunk of maple. Moth in 

 June and July. 



Montreal, Canada, to Long Island, New York, western Pennsylvania and Illinois. 

 New York: Buffalo, Bock City, Ithaca, Ilion, Speculator, Schenectady, Albany, 

 Staten Island; Brooklyn and Newtown, Long Island. 



9. C. fulvipes Harris. Anal tuft lanceolate; hind tibiae rough-hairy the whole 

 length and only slightly more so at the spurs; transitional to Sannina. Black; 

 fore wing with terminal edge, only, scaled; a few red scales beyond discal dot. 

 Front of palpi, all tibiae, and most of hind metatarsi orange. An orange band on 

 under side of abdomen. 22 mm. 



Hymers, Ontario, to Massachusetts. New York: Big Indian Valley, Catskills. 



10. C. saxifragae H. Edwards. Similar to 8. fulvipes; border of fore wing extend- 

 ing in a third way to cell; middle and hind tarsi almost wholly orange; abdomen 

 apparently solid black. 20 mm. (henshawi H. Edwards). 



Labrador; Colorado. 



11. C. pictipes Grote and Robinson. Sometimes like male exitiosa, except as noted 

 in the key; typically smaller, and with outer half of most of the scales in the anal 

 tuft yellow; palpi more yellow, R 3 and R 4 of fore wing normally more shortly 

 stalked. Female like male, but usually with hind tibiae and terminal tuft almost 

 wholly black. 15-25 mm. (H 46:24.) 



General in June. Larva usually under bark of trunk and large branches of 

 cherry, plum, June-berry and other Rosacea? ; also on chestnut ( castanece Busck ) . 

 Not so common on peach nor so injurious as C. exitiosa, but much confused with it.

 ings Center, New York City, Staten Island, Brooklyn. 



12. C. rubristigma Kellicott. Palpi black, the scaling in front yellow; antennae
