AMERICAN LEPIDOPTERA. 295 



I place this genus here doubtfully, as I am not altogether sure it 

 is a Geometer. The venation of the hind wings is about as much 

 like that of the Sterrhinse as of this subfamily, but, in other respects 

 while peculiar, it seems better placed here. I have no % , and can 

 give only the character of the % antennse, which was the only 

 structual character of the % given by Mr. Grote. 

 Species. — 31. auricinctarium Grt. 



2. SYNOMIL,A n. gen. 

 Type, subochreata Hulst. 



Palpi short, slender ; tongue obsolete ; front flat ; antennae filiform 

 pubescent in both sexes ; hind legs without spurs, weak, somewhat 

 aborted in % ; fore wings one accessory cell, 12 veins, 6 separate ; 

 hind wings 8 veins, 3 and 4 separate, 6 and 7 stemmed, 8 with cell 

 nearly to middle.

 Vera. 301, 1818. 



Type grataria Fab. 



Palpi short, slender ; tongue developed ; front bulging, flattened ; 

 antennae strongly bipectinate in S , simple in 9 ; hind tibiae with 

 two pairs of spurs in both sexes ; fore wings, one accessory cell, 12 

 veined, 6 separate ; hind wings 8 veins, 3 and 4 separate, 6 and 7 

 .stemmed ; 8 joined with cell, but separating before middle. 

 Species. — H. grataria Fab. 



4.. PAOTA n. gen. 

 Type fuUaria Grt. 



Palpi moderate, slender, porrect ; front flattened, scaled, untufted ; 

 tongue developed ; antennae shortly bipectinate in % , with a fascicle 

 of hairs on each pectination ; hind tibiae with all spurs ; fore wings 

 12 veins, one accessory cell, 6 and 7 separate; hind wings 8 veins, 

 3 and 4 separate, 6 and 7 stemmed, 8 joined with cell nearly to 

 middle. 



Species. — P. fultaria Grt. 



STERRHIN^. 



The Sterrhinae are a group separated by the peculiar merging of 

 vein 8 of hind wings with the cell. They are, in the main, small, 

 frail insects, and in the more specialized forms show decided pecu-
