20. C. ithacae Beutennmller. 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.

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

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



In female aberration brunneipennis H. Edwards, the border reaches more than 

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

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

7. MGEBIA Fabricins 



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



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

 laminate below; female antenna 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, more curved, and less widely separated from Cu x than usual; hind wing 

 with M 3 and CUj 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. M. 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

 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
