Holotype: U.S. National Museum No. 69717. 
Type-locality: Dominica, .5 mile east of Pont Casse (13 January 
1965; J. F. G. and Thelma M. Clarke). 
Distribution: Dominica. 
Food plant: Unknown. 
Described from the holotype male and 7 99 paratypes as follows: 
2 99, Springfield Est., 20-26 July 1963; 2 99, .4 mile east of Pont Casse, 
23 June 1964, 21 May 1964; 9, 1.6 miles west of Pont Casse, 16 June 
1964 (all collected by O. S. Flint); 9, 1 mile east of Pont Casse, 1800 
feet, 29 January 1965 (J. F. G. and Thelma M. Clarke); 9, Pont 
Casse, 7 June 1965 (Don R. Davis). 
Only eight specimens of insuwlana came to hand during many nights 
of collecting over a two-year span. Moreover, all were collected within 
a radius of three miles although the island was covered, during the 
two-year period, by many collectors. At best the species is rare. 
This is an unusually interesting species for two reasons: First, it 
is the only representative of the family Oecophoridae and the sole 
representative of the genus Gonionota on the island. Both the family 
and the genus are highly developed in the neotropics yet only the one 
species has succeeded in establishing itself on Dominica. Second, it is 
unusually variable, a characteristic seldom found in the genus Goni- 
onota. In plate 2a I have illustrated the only male available that shows 
a clearly defined pattern and contrasting coloring. Plate 26 illustrates
