A REVISION OF THE DELTOID MOTHS SMI'I'II. 11 



Th«' fore tibia in tlio male lias tlu; process very lar^c, mop-like at ti]), 

 with the dense mass of scales, but without a special iuiir pencil. The 

 long tarsal Joint is furnished with a small pencil, seemingly not capa- 

 ble of expansion, and rather ornamental, and also with a ladle-like 

 appendage toward the tip, similar to that in lldcrofjranima. It would 

 be almost impossible to mistake this genus, with which tiie present 

 tribe may be closed. 



The (;haracters of tlie Ilypenini as compared with tlie Ilcrminiiuiare 

 largely negative, thar is they possess none of the specializations in which 

 the latter are so rich. Tlie male fore legs are quite normal, the antenna' 

 are at most ciliated and to all appearance not unlike those of the female. 

 The palpi are all after one type, long or moderate, obli(]ue or straight, 

 never closely ai)plied to the front or recurved, second Joint always 

 straight, with upright vestiture as in the second group of Ilerminiiui. 

 While there are no sexual modihcations of a secondary character in 

 this tribe, the male is quite usually larger, nearly always more somber 

 and even in color, without strong contrasts; the fenuile is often quite 

 brightly and contrastingly marked. Often the male is also much 

 more robust, clothed with loose woolly vestiture on the legs and under- 

 side, while the palpi are frequently shorter and more oblique. A^ a 

 whole the species in this tribe are darker colored and do not have the 

 frail or thmly scaled appearance characteristic of the Herminiini. 

 With the exception of Cajns all the genera have the abdomen with a 

 series of little dorsal tufts, (»f which that at base is most prominent. 

 These tufts are round, small, truncated at tip, scaly, and very easily 

 removed by slight rubbing; therefore it is rarely that a ([uite i»erfect 

 specimen can be found. 



Ca2)is is the aberrant genus of the tribe, and I am not at all con- 

 vinced that it IS really a Deltoid. The palpi only sei)aratc the si)ecies 

 from the Caradr'DKt scries, though vein h\e of the secondaries is usually 

 quite strong; yet this is a somewhat variable feature in the species. 

 Even the palpi arc not strictly Deltoid in character; for although they 

 are longer than usual and obli(jue, yet the vestiture is directed in both 

 directions and the se(;ond Joint is rather clavate at tip. As in this 

 tribe the palpi tend somewhat in this direction, I did not feci myself 

 Justilied in excluding the genus. It differs from all the others in the 

 tribe by its complete lack of dorsal tuftings on the abdomen, by the 

 short palpi, and by the short obtuse wings. 



SuVki is a true Hypenid genus Avith moderatelj' long, quite oblique 

 palpi, forming with the prominent frontal tuit a distinct snout. The 

 wings are moderate, widening regularly from the base; the apices are 

 acute, the outer margin very ojblique. The markings are (]uite charac- 

 teristic, fornung obli([ue i)alc bands on a pearl-gray ground. 



HoinolocJta is the genus most numeritusly represented in our tauna 

 and it includes somewhat divergent forms. The palpi range from mod- 

 erate to very long, rigidly straight to oblKpie, and there may or may 

 not be a sexual difference in tliis particular. The wings are always
