slight varieties. In this view Mr. Butler now agrees with me. A Guatemala example 
is figured. 
ACRIBIA. 
Acribia, Felder, Reise Nov. Lep. iv. p. 1, t. ciii. f. 14. 
This genus is very close to Phaloésia, but I think distinct, on account of the shorter 
and broader wings of the female. 
1. Acribia melanchroia.

Phaloésia melanchroia, Butl. Ann. & Mag. Nat. Hist. 4th ser. xvi. p. 171. 
Hab. Mexico (Bilimek)1; Guatemaua, El Jicaro, Cubilguitz (Champion). 
The male of this species is quite unknown to me. 
2. Acribia maculifrons. (Tab. XI. fig. 3.) 
Stenele maculifrons, Walk. Cat. xxxi. p. 157°. 
Hab. Guatemata, San Gerdénimo (Champion); Honpuras, Limas!; Costa Rica, 
Trazu (Rogers). 
The example from Costa Rica is much faded; I believe it to be afemale. In neura- 
tion it agrees well with A. melanchroia. 
HYALURGA.

Hab. Panama, Bugaba 800 to 1500 feet (Champion).— VrnuzvELa1?; Gurana,

The only specimen of this insect I have seen from our country is the one obtained by 
Mr. Champion. In South America it is common, and generally distributed over a wide 
range of country. ‘The specimens before me vary very considerably in the amount of 
the orange-coloured margins to the wings; and I feel pretty certain that several closely 
allied forms recently described will, upon sufficient material being obtained, prove to be 
nothing but very slight varieties of this insect.
