TIOGA, Ilul^t. 

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



Ento. Am., IV, 113, 1888. 



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

 end member short in (^'' ; end member in O slender, pointed, (]uite long. INIaxillary 

 palpi pencil tufted. Process short. Wings in ,-5'' as usual, with ^cale jiad and vitreous 

 spot beneath, the vitrifaction small. Legs— tarsi s|-)inulated at tip only. Tiljial epi- 

 ]ihysis short, small. Spurs of middle and hind legs long, the hind lilna.' havnig two 

 pairs. Venation— Fore wing II veins ; c^ with, it seems to me, 11 wanting ; Other- 

 wise much after the pattern of Lanthaphv, but 2 and 3 are slightly bent and the 

 lower median is not much swollen. f^>, l lurcate near base, 3 near angle, 4 and 5 

 from a point, 6, 7, 8 and 9 stemmed, 11 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 : antenmv dark fuscous ; thorax 

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

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

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

 outer line lig'ht gray, edged within with black ; outer field fuscous ; veins lighter, a 

 row of submarginal black spots ; hind wings yellowish brown, blackish along edge. 



Texas, April. This has very decidedly the appearance of Hemi- 

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

 while in Hemimatia Xhty are wanting". On this account also Hcmiwalia 

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



TETRALOPHA, Zell. 

 ( Tctra, low-, 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., Y\\ 114, 1888. 

 Kaiona, Hulst, Ento. Am., IV, 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 §,6 is separate from 7. 



In view of the radical difference in venation between (^ and 9 ''^"d 

 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.
