AMERICAN LEPIDOPTERA. 251 



hind wings 8 with cell nioi-e than half its length ; in t there is a 

 lobe at base along inner margin folded over upwards forming a sort 

 of pocket ; frenulum wanting. 



Differs from Trichopieryx in having only one accessory cell, and 

 fi'om Fhilopsia in that only one pair of spurs is present on hind 

 tibiae, and from both in the absence of the frenulum. 

 Species. — C. viridata Grt. 



3. MYCTOBIA u. gen. 

 Type limitata Wlk. 



Palpi moderate, erect ; front not tufted ; antennae filiform, ciliate 

 in both sexes ; thorax and abdomen untufted ; fore tibiae unarmed ; 

 hind tibiae with end spurs only ; in S there is a slight pencil of long 

 hairs on inner side ; fore wings 12 veins, two accessory cells, 6 and 

 7 stemmed ; hind wings 8 with cell to beyond middle, 6 oeparate 

 from 7 ; in % there is a folded lobe at base on inner margin above ; 

 frenulum wanting. 



The hair pencil on the hind tibiae of % is rarely met with in this 

 section of the Geometers. Mr. Meyrick does not consider it a generic 

 character, regarding it as variable and uncertain, but after much 

 comparison my own opinion is, it can be fully relied upon, and is a 

 most excellent limitation. By this Nydobia is separated from Lo- 

 bophora Curt., as well as by the absence of the frenulum. 

 Species. — N. limitata Wlk. 



N, fusifasciata Wlk. 



4. €1.ADARA n. gen. 

 Type atroHturata Walk. 



Palpi short, porrect, rough scaled ; tongue developed ; front 

 smooth ; antennae of % filiform ; thorax and abdomen smooth ; 

 hind tibiae with one pair of spurs in both sexes, without hair pencil ; 

 fore wings with two accessory cells, 12 veins, 6 with 7; hind wings 

 with folded lobe at base above along inner margin in ^ ; 8 veins, 

 6 and 7 separate, 8 with cell to beyond middle ; frenulum wanting. 



Differs from Nijctobia in the absence of the hair pencil on hind 

 tibiae of % ; from Triehopteryx Hubn. in that 8 is joined with cell 

 in hind wings ; from Lobophora Curt, in that it has one paii" of 

 spurs on hind tibiae. From both the latter as well in the absence 

 of the frenulum. 



Species. — C. atroHturata Walk.
