242 HETEROCERA. 
1. Contrebia extrema. 
Contrebia extrema, Walk. Cat. ix. p. 184’. 
Hab. Honpvras (Dyson 1). 
This species is only known to me by the type in the National collection. 
ETOBESA. 
Etobesa, Walker, Cat. xxxii. p. 471. 
Walker included in this genus a single species, FE. ligneata, from the Amazons; 
Edema sylinoides, Walk., from Colombia, would appear also to belong to it. The 
latter extends northwards into our region. 
1. Ktobesa xylinoides. 
Edema «xylinoides, Walk. Cat. xxxv. p. 1931". 
Hab. Mexico, Cordova (Riimeli); Panama, Bugaba 800 to 1500 feet (Champion).— 
Cotomsia, Santa Marta !. 
Two examples: the one from Mexico agrees fairly with Walker’s type ; the other from 
the State of Panama is altogether darker in colour, but has the markings almost similar, 
the greatest difference being in the colour of the abdomen—in the former quite pale 
fawn-colour, in the latter dark brown. Our material is not sufficient for me to venture 
to describe the Panama insect, but it is quite likely that upon receipt of more specimens 
it may prove to be distinct. 
PHYA. 
Janassa, Walker, Cat. v. p. 1101 (nomen przoc.). 
Walker founded this genus upon a single species, J. lignicolor, from an unknown 
locality; this insect is now known to come from North America, and quite lately 
Mr. H. Edwards has described a second species from our country. The name Janassa 
being preoccupied in Pisces, it is necessary to change it. 
1. Phya laciniosa. 
Janassa laciniosa, H. Edwards, Entom. Amer. i. p. 129°. 
Hab. Mexico, Jalapa (Schaus1), Mazatlan (H. Edwards’). 
Unknown to me. 
TIFAMA. 
Tifama, Walker, Cat. v. p. 1077. 
Two species were placed in this genus by Walker, Z. simois (Cram.), and, 
doubtfully, 7. ziliante (Cram.), both from Surinam; Tifama also includes several
