234 THE CANADIAN ENTOMOLOGIST. 



ent and the front terminates in a wide-lipped protuberance, centrally 

 flattened, its lower edge exserted. In Friiva fasciatella the infra-clypeal 

 plate is also prominent, the front is elevated and is crowned by a shallow, 

 wider and more narrowly edged and rounded depression. Structurally 

 Fruva is more closely allied to Erotyla than Spragueia, as we shall see in 

 discussing the neuration of F. obso/eta, yet in ornamentation the resem- 

 blances are reversed. 



Spragueia guttata Grote. 



Fore wings 12-veined, 8 and 7 together from the extremity of the 

 accessory cell, 9 out of 8, a long furcation to costa, the accessory cell 

 smaller than in the other species. Hind wings 7-veined. 



This species has very distinct ornamentation, the fore wings being 

 light sulphur yellow crossed by black lines ; the only orange is at base on 

 internal margin, and a band running upwards on median space within the 

 t. p. line, interrupted by the black-ringed, sulphur-yellow, spherical reni- 

 form, and extending beyond it to apices. The fringes are orange, touched 

 with blackish at apices, opposite the cell, and again about internal angle. 

 It has been collected by Heiligbrodt in Bastrop Co., Texas. 



The wings are narrower in Spragueia. The neurational characters 

 which distinguish the North American genus from the European Erotyla 

 (Agriphila) are first the 7-veined secondaries, with the three-branched 

 median vein wanting the weak vein 5, while the cell is longer. Then the 

 longer vein 9 of the primaries, while in all the species except onagrus, veins 7 

 and 8 spring together from the extremity of the accessory cell ; in onagrus 

 they are joined on a shorter stem than in Erotyla sulphuralis. 



Fruva fasciatella Grote. 



fore wings r2-veined, veins S and 7 out of the extremity of the acces- 

 sory cell, 9 a long furcation. Hind wings with vein 5 obsolete. The 

 genus differs from Spragueia in the bulging clypeus surmounted by a 

 shallow cup-like depression. But there is a faint indication of an inde- 

 pendent vein on hind wings at the cross-vein, immediately beyond which 

 it vanishes. 



This species varies in the color of the indefinite shadings of the pri- 

 maries from dusky olivaceous to ochreous. The discal dots and t. p. line 

 are more or less evident. It is common in Texas.
