medially; the purplish red colour not strongly papers with the broad black 
tergite hind margins. [¢ unknown] - : : . F. blattina 
[This species is known only from the 2 holotype)” 
7 Abdominal pattern consisting of golden green, coppery green or reddish copper 
metallic bands on T3—-T5 which strongly contrast with a black centre line and 
black tergite hind margins; the metallic bands on each side usually nil has 
arcuate, especially on T3 and T4. [Moluccas and New Guinea] - 8 
— Abdomen rather uniformly dark, the inconspicuous pattern consisting of a wang 
dark blackish green or slaty bluish band across each tergite from T3—T5 which is 
not medially interrupted and only very feebly contrasts with the black hind 
margin of the tergite; bands not at all arcuate. [Bismarck Archipelago] . : 10 
8 Calyptrae pale yellowish brown with pale yellow fringes; long fringe hair of outer 
side of upper calypter conspicuously yellow. Wing bases yellow-brown to naked 
eye. [Moluccas] F g . F. fervens 
— Calyptrae brown or dark inca with pale own to dark brown fringes; long outer 
fringe hair of upper calypter quite distinctly brown. Wing bases dark brownish 
to naked eye. [New Guinea] : 9 
9 Metallic fascia on each side of T5 with its hind es excarate and therefore nar- 
rower on the centre part than at the inner end (the metallic band only reaching 
back to the level of the transverse row of setae at the inner end) : F. mirabilis 
— Metallic fascia on each side of T5 not noticeably excavate on the hind margin, 
extending back as far as, or almost as far as, the transverse row of setae (metallic 
band not wider at its inner end than elsewhere) : : F. callipygos 
to Mesonotum and scutellum golden green to blue-green. Basicosta yellowish on 
posterior part and only infuscate anteriorly. [New Britain] . : F. gemmata 
— Mesonotum and scutellum mainly metallic coppery red or coppery purple, some 
coppery green colour on edges of prescutum and scutum. Basicosta uniformly 
black. [New Ireland] . F. bracteata 
1x1 Abdomen uniformly purplish black (at most with paler reddish purple tinge on T3). 
Eyes of J very nearly meeting, frons at narrowest subequal in width to anterior 
ocellus and 0-03 of head-width. [Solomon Islands, ? also New Britain] 
F. solomonicola 
— Abdomen black with brilliant metallic transverse bands on T3-T5 ranging from 
golden green to greenish copper to silvery blue-green. Eyes of ¢ slightly more 
separated, frons at narrowest about one and a half times as wide as anterior 
ocellus and 0-05 of head-width. [New Britain] ‘ ; : : F. heinrothi 
Subgenus PSEUDOFORMOSIA Brauer & Bergenstamm 
Pseudoformosia Brauer & Bergenstamm, 1889 : 126 (58). Type-species: Formosia moneta 
Gerstaecker, 1860, by monotypy. 
Laccura Enderlein, 1936 : 431. Type-species: Rutilia saturatissima Walker, 1861, by original 
designation. Syn. n. 
Diacnosis. Head partly metallic, at least on upper occiput and genal dilations. Head 
of $ almost fully holoptic, upper interfrontal area eliminated by meeting of parafrontals, frons 
at narrowest hardly wider than anterior ocellus. Eyes of ¢ sometimes with upper facets en- 
larged. Arista short plumose, hairs much longer than basal thickness of arista. Mentum of 
proboscis rather slender, tapering distally. No posthumeral setae (trace of such setae present 
in occasional specimen). Usually one pair of small presutural dorsocentral setae present 
(occasionally undeveloped, especially in ¢ of moneta). One post ia seta (occasional specimens 
aberrant and without such seta or with trace of very small second post ia in addition). Two 
sternopleural setae (1 + 1), rarely with a supernumerary third seta in addition. Postalar 
callus with 4-6 setae, rather variable in degree of development. Scutum without supernumerary
