low above and broadly so, below. Legs black; yellow at spurs and joints. Fore 

 wing with border reaching about a third way in to cell; more or less yellow-scaled; 

 discal bar narrow; black. Small, expanse typically about 12 mm., but quite 

 variable in size, (kcebeli H. Edwards). (H 46:25, enlarged.) 



May; late July. Larva boring under bark of trunk of apple, pear, etc. 



White Mountains, Xew Hampshire, to California. Xew York : Honeoye Falls,

 black in male, with a white bar in female, as in related species. 15 mm. 



June and July. Larva in solid wood of willow and poplar; also in galls. 

 Generally distributed. Xew York: Catskills, Karner, New York City, Brooklyn. 



20. C. ithacse Beutenmiiller. Fuscous (probably black when fresh) ; palpi black 

 below, at least in female; border of fore wing extending half way in to cell in 

 male, and farther in female, leaving four or five hyaline spots; legs with a little 

 pale at spurs and segments; abdomen apparently wholly fuscous (type lot only 

 seen, all of them in bad condition). 15-20 mm. 



End of June to early August. Larva in Heliopsis. Piipa in the ground. 

 Pennsylvania. Xew Y'ork: Ithaca. 



21. C. rileyana H. Edwards. Antennae of male blackish, of female reddish at 

 base; palpi yellow, the outer face black in male. Fore wing with four to six 

 transparent cells beyond the discal bar, which is bright orange red outwardly. 

 Inner margin of fore wing also with red scales. Hind tibiae yellow, black between 

 spurs; metatarsi yellow; abdomen with yellow stripes on all but first segment. 

 Border of fore wing quite variable, linear in var. hyperici H. Edwards. 20-30 mm. 



In female aberration brunneipen-nis H. Edwards, .the border reaches more than 

 half way to the cell, leaving only three hyaline spaces. 

 July and August. 

 District of Columbia to Xorth Carolina, and west. 



22. C. sigmoidea H. Edwards. Palpi mostly yellow; hind tibiae with black 

 outer side; metatarsi yellow, contrasting with tibiae and rest of tarsus; abdomen 

 with bands stronger, on alternate segments; the terminal, tuft narrowly tipped 

 with yellow, as in exitiosa. Fore wing with discal dot red, largely mixed with 

 black; border not reaching halfway to cell; sometimes very narrow. 20 mm. 



August. Larva in stems of black willow. A seaside species. 

 Walpole, New Hampshire, to Long Island, New York. Xew York: Amagansett, 

 Long Island. 



7. 2EGEEIA Fabricius 



(Sphecia Hiibner; TrochiHum auct., Hiibner, in part) 



Palpi as usual, hairy below toward base; male antennae unipectinate and 

 laminate below; female antennaa simple. Tongue weak, completely covered by 

 palpi when coiled; hind tibiae loose-hairy, without tufts at spurs; abdomen with 

 a small short tuft. Fore wing normal (fig. 225) ; R 5 running to outer margin. M 2 

 and M 3 more curved, and less widely separated from Cu^ than usual; hind wing 

 with M 3 and Cu, shortly stalked or rarely connate; the genus distinguishable from 

 Memythrus in the latter case, by the erect discocellulars of the fore wing, and 

 the strongly oblique and very long Idcv of the hind wing. 



1. JE. apiformis Clerck (The hornet moth). Sides of face, front of palpi, sides 

 of back of head, vertex, front half or more of tegulse, and metathorax, yellow; the 

 rest of head and thorax dark brown. Abdomen banded with blackish and yellow; 

 with segments two and four normally with more black than the others. Tibiae 

 'and tarsi more orange. Wings transparent, fore wing scaled along costa to middle 

 of cell R 4 , and with slight streaks in middle of a few lower cells; otherwise with
