KEY TO FIJIAN SPECIES of Febra 
1. Pronotum very coarsely punctured, 
hardly more than ten punctures in an 
approximate line medially from apex 
to base; elytron heavily punctured. .2 
Pronotum not very coarsely punctured, 
much more than ten punctures along 
median line; elytron generally sparsely 
punctured 3 
2(1). Elytral punctures very close, only partly 
in regular rows; green above 
varioloidea 
Elytral punctures not extremely close, 
in separate distinct rows; reddish above 
rubra 
3(1). Third antennal segment much longer 
than second; elytron not striped; length 
over 5 mm 4 
Third antennal segment barely longer 
than second; elytron striped; length 
under 4 mm. 5 
4(3). Pronotum distinctly punctured; ely- 
tron black, very finely punctured 
insularis 
Pronotum not distinctly punctured; 
elytron reddish to partly or entirely 
metallic blue, subcoarsely punctured . . 
venusta 
5(3). Pronotum striped medially, minutely 
punctured; suture not distinctly black 
basally; elytron not almost entirely 
black in posterior half. n. nigroornata 
Pronotum not striped medially, im- 
punctate; suture distinctly black bas-

130. Febra venusta Clark 
Febra venusta Clark, 1864, Jour. Ent. 2: 262, 
pi. 12, fig. 5 (Fiji; type in Brit. Mus.). 
Febra semiaurantiaca Fairmaire, 1882, Soc. Ent. 
de France, Ann. Ser. 6, 1: 490 (Ovalau); 
n. syn. 
Male: Ochraceous, slightly darker on an- 
tenna, posterior two-thirds of elytron and 
hind leg. Head and pronotum practically im- 
punctate, latter with an irregular transverse 
row of spaced punctures in basal depression; 
scape shorter than third segment; elytron with 
punctures distinct but well spaced, in sub- 
regular rows. Length 5.5 mm. 
Female: Scape longer than third antennal 
segment; posterior two-thirds of elytron met- 
allic bluish. Length 6 mm. 
Maulik indicated the common identity of 
the above two names by his identification 
labels; venusta being the male and semiauran- 
tiaca being the female. 
viti levu: Naivithula, Tailevu, Sept. 1937, 
Valentine, both sexes; Tholo-i-suva, Sept. 
1950, Mar. 1951, Krauss. 
ovalau: Type locality of semiaurantiaca. 
vanua levu: Three, Nakawanga, Oct. 8, 
1955, Gressitt. The males are colored sim- 
ilarly to those from Viti Levu, but the female 
has the elytron entirely purplish blue. Pos- 
sibly a weak subspecies is involved. 
HOST: Nephrolepis sp. (fern); the larva is a 
leaf-miner.
