TIOGA, Hul^t. 

 [Tioga, a tribe of Indians of New York and Pennsylvania). 



Ento. Am., IV, 113, 18S8. 

 Palpi long, thin, scaled, extending much above head. 2nd member very long, 

 end member short in (^ ; end member in Q slender, pointed, qiiite long. Maxillary 

 palpi pencil tufted. Process short. Wings in rj' as usual, with scale pad and vitreous 

 spot beneath, the vitrifaction small. Legs— tarsi spinulated at tip only. Tibial e]ii- 

 physis short, small. Spurs of middle and hind legs long, the hind tilii.v having two 

 pairs. Venation — Fore wing 11 veins ; rj' with, it seems to me, il wanting ; other- 

 wise much after the pattern ot Lanikap/n-, but 2 and 3 are slightly bent and the 

 lower median is not much swollen. ^J , i turcatc near base, 3 near angle, 4 and 5 

 from a point, 6, 7, 8 and g stemmed, II wanting,', 10 and 12 separate. Hind wings, 

 3 close to angle, 4 and 5 stemmed, 6 widely separate, 7 and 8 stemmed beyond cell. 

 Cell short. 



T. aplastella, Hulst. 



Hulst, [Tioga), Ento. Am., IV, 113, 18S8. 

 Expands, 18 to 20 mm. Head light gray : antenna? dark fuscous ; thorax 

 blackish gray ; abdomen yellowish brown ; base of each segment blackish ; fore 

 wings light gray ; basal field blackish, limited by a light gray cross line edged with 

 black on either side ; basal half of middle field of ground color, outer half fuscous ; 

 outer line light gray, edged within with black ; outer field fuscous ; veins lighter, a 

 row of submarginal black spots ; hind wings yellovvi>h brown, blackish along edge. 



Texas, April. Tfiis has very decidedly the appearance of Henii- 

 matia scortialis. Led., but the maxillary palpi are present and distinct. 

 while in Hcmi?natia they are wanting. On this account also Hemitnatia 

 can not be L. diluculella, Grote, which also it resembles. 



TETRALOPHA, Zell. 



( Tetra, foui", and lophc, crest |. 



Isis, p. 880, 1848. Grote. Geol. Terr. Bull., IV, 688, 1878, 



N. A. Ent. I, 10, pi. II, f. 5, 1879. 

 Wanda, Hulst, Ento. Am., IV, 114, 1888. 

 Kaiona, Hulst, Ento. Am., W. 113, 1888. 

 Loma, Hulst, Ento. Am., IV, 113, 1888. 

 In all respects very much the same as Tioga, except that in fore wings i is never 

 furcate, and in O, 6 is separate from 7. 



In view of the radical difference in venation between (^ and C ancl 

 the variability of 4 and 5 in both wings, I established a number of 

 genera, which further stud}- has led me think must all be referred to 

 Tetralopha.
