Male antemiai well pce^iiiated, in the less typical species (^.s7//;n".ss«;vr/j about 

 half as long as usual; female anteiiiitc simple. I'alpi very loii<j, porrecl, pointed, 

 the third joint long and extending sometimes l)y a head's length beyond the 

 (Vont, or, as in T. waf;coi(i iu\i\ s/fhrcssarla, they are short and not much longer 

 than in Sei)iiot/iifia,\\H' third joint beiiiii small and depressed. A lon^ (loul)le 

 "tuft of hairs projects between the palpi. Fore wings very tiilcate, tin; apex 

 produced, and the outer edge excavated below tiie apex, with a dark line 

 l)ordering the excavation; the outer edye is full Ix'low the excavution. The 

 costal region is considerably wider; the ^ulicostal venules longerthau in Seiiti- 

 of/iisa; the first subcostal venule is about a t()urth longer than the subcostal 

 areole, which latter is long, narrow, and curvilinear, as in Srjiiiofhisa, other- 

 wise the venation is very similar to that of Sc/niofh/sa. Hind wiiiirs in the 

 male with a prominent angle in the outer wings, as distinct or more so than in 

 any species uf Semiofltha ; in icuvar'ia and suhrcssaria less distinctly auifular, 

 and much as in most of the s[)ecies of Seiiiiotliisd ; in the i"einale, tiie outer 

 edge is bent, but not distinctly angular. The abdomen is much longer and 

 slenderer than in Seiniothisa, luul reaches to the inner angle of the hind wings. 

 Legs much as in Semiotlimt, long and slender; hind til)ia' long, lajt swollen, 

 and with the four spaces as usual. The species are eitiier clear ochreous- 

 brown. with two distinct lines on the fore wings, or with markings similar to 

 Semiothim. 



V This genus is recognized by tlu; well-pectinated antenn;v and long palpi; 

 the species difier but slijihtly from those ol' 8ei)iiothisa in other points. lu
