palpi short. Front with a moderately prominent, rather wide, cup- 

 shaped projection, nearly hidden by the erect vestiture, and with a 

 central protuberance, not reaching beyond the rim of the cu]), set 

 in erect \'estiture, which hlls the cup itself. (The clypeal projections 

 are thus evident-y modifications of the clypeal surface. So far as I 

 have observed they are not sexual peculiarities in the moths). Ves- 

 titure mixed, fl;;ttened hair and scales. The single species is of the 

 size of Eiistrofia carneola. 



I. Escaria clauda Grt., Papilio ii, iS6. 



Grayish fuscous. In the male the ornamentation is better 

 written. Orbicular paler, spherical; claviform moderate, its upper 

 edge accentuated in black. Reniform lunate, moderate; the lines 

 fine, perpendicular, edged with pale or whitish, especially in the 

 female, which is darker, and the white s. t. line quite prominent. 

 Hind wings pale fuscous, trace of median spot and extra mesial line. 

 A vague terminal band. Beneath g-rayish fuscous, with common 

 line and faint discal spots. One specimen, probably a variety, 

 showed a reddish cast. Expanse 29 mil.

The structure of the genera Fniva Grt., which is nearest to the 

 European genus Erotyla in character, although in ornamentation the 

 American genus Spra^ueia Grt. more nearly accords with the Eu- 

 ropean Erotyla trahealis Sc. (= siilphuralis Linn.) Xajiihoptera 

 Guen., Spnigueia Grt., and Exyra Grt., has been explained by me 

 in Can. Ent. xi, 231, and need not be repeated here. 



Gen. PROTHYMIA Hiib. 

 The palpi are curved and pointed, exceeding the iront, the ter- 

 minal joint long and attenuate. The fore wings have the external 

 margin somewhat rounded; hind wings full. The abdomen is slightly 

 flattened. These characters are drawn from the European P. virid- 

 aria, and to this genus the late Mr. Morrison referred two species 

 from eastern North America, viz.: i, coccineifascia Grt.; 2, rosalba 

 Grt.; while I have described 3, plana Grt. from Arizona; and 4, 

 orgyia Grt. from Texas. Of these plana resembles, in ornamenta- 

 tion, the European Metoponla kwkeyitziana Hiib. I ha\-e not been 

 able to compare the two insects. 



Gen. EUHERRICHIA Grt. (1SS2) 

 This genus has the form of Eiish'otia, but the purple colors of 

 Callopistria { Erwpus), to which Hadenoid genus Guenee referred 

 our North American species. Dr. Herrich-Schaeffer, in his "Cor-
