THE CANADIAN ENTOMOLOGIST, 235 



Fruva obsoleta Grote. 



Fore wings 12-veined, veins 6 and 7 out of the extremity of the acces- 

 sory cell, 9 a short furcation. Hind wings with vein 5 weaker, but dis- 

 tinctly present. 



The neuration approaches Erotyla more closely than the other species 

 in the presence of the weaker vein 5 on the secondaries, and the short- 

 ness of vein 9 on fore wings. The position of 8 and 7 on fore wings is, 

 however, as in fasciatella, being separate at base. The species has uni- 

 colorous, dusky olive-fuscous primaries, a little paler shaded over costal 

 region at base, and showing a variable ochrey reflection exteriorly. No 

 markings. Illinois and Texas in June. 



I have a single specimen of Fruva acerba Hy. Edw , from California, 

 which seems allied to fasciatella. 



Xanthoptera nigrofimbria Guen. 



I restricted, Trans. Am. Ent. Soc, 295, 1873, the genus Xanthoptera 

 to this type, proposing in the Check List, 1875, Exyra, with the type 

 semicrocea, for the hairy species with differing venation and which are 

 found to feed in the larval state on the species of Sarracenia, or pitcher 

 plants. Guenee"s single species of Exyra was only known to him through 

 Abbot's drawing. 



In nigrofimbria the fore wings are 12-veined, the accessory cell longer 

 than in Spragueia, veins 7 and 8 separate at base, 9 out of 8 a rather long 

 furcation. Hind wings 8-veined, cell closed, vein 5 hardly weaker than 

 the rest. The palpi are rather long and free from the front with well 

 developed terminal joint, closely scaled. The front is smooth, rather 

 wide and slightly elevated with a shallow depression and discolorous rim. 

 The thorax and head are closely covered with flattened scales. The fore 

 wings are rather broad with produced apices. 



Xanthoptera semiflava Guen. 



Fore wings 12-veined, 8 and 7 joined at base, 9 out of 8, a long fur- 

 cation. Hind wings with vein 5 very faintly indicated. Head and 

 thorax closely scaled. Front globose. 



This species differs from the following species of Exyra by the closer 

 squamation and the wide, slightly elevated front, in which it agrees with 

 nigrofimb) ia. But there seems to be no rim and shallow depression in the
