Not unicolorous dark species, dorsum of thorax and usually also much of the abdomen 
metallic greenish, cupreous, blue or violaceous, the abdomen always noticeably 
banded or patterned. 3 
Hair of occiput and Sostbaecee all BEeee Head pollinosity distinctly bicolorous, 
white on lower parts of parafrontals and on parafacials, postorbits, and most of 
genae, and pale golden brown on upper parts of parafrontals and on occiput, facial 
carina, antennal foveae and epistome (golden brown colour of parafrontals best 
seen from above). Thorax without white pollinosity, with only merest trace of 
yellowish brown pollinosity thinly over humeral calli and fore margin of prescutum. 
Dorsum of T5 with a pair of widely separated golden green subtriangular metallic 
areas which extend back only about as far as the main transverse row of setae. 
[Batjan] - : F. atribasis 
Hair of occiput rete or ellen ini of pastbdcase neal ae ie but occasionally 
brownish. Head pollinosity unicolorous white, greyish white or yellowish white. 
Thorax usually with some white pollinosity on prescutum and humeral calli, often 
also on mesopleuron and sternopleuron. Dorsum of T5 with metallic areas 
not of thisform . 4 
Dorsum of abdomen with pon Goiel eoppery na or eae bands on each side Gf 
T3-15 which are clearly separated medially on all tergites (T3, therefore, as well as 
other tergites with distinct black median vitta); the dark colour of the metallic 
bands not strongly contrasting with black areas of tergites and abdomen appearing 
generally dark. Wings very conspicuously brown. [Run Island and Buru] 
F. engeli 
Dorsum of abdomen with a bold pattern of golden green, reddish green, emerald or

posterolateral corners of the tergite and a very fine inconspicuous median line 
black. 9 without definite sternopleural pollinose spot and with rather thin white 
pollinosity over mesopleuron which has a distinctly shifting appearance from differ- 
ent angles. Upper occiput metallic greenish adjacent to the postocular setulae. ¢ 
frons at narrowest 0:14-0:15 of head-width. [Moluccas and West Irian] 
F. complicita 
Abdominal T5 with metallic areas confined to middle part of tergite dorsum, some- 
times evanescent so that T5 is virtually all black in J, metallic areas of T5 dorsum 
usually in form of two irregular elongate golden green areas which nearly meet 
posteriorly in the tergite depression and together are roughly V-shaped. 2 with 
a small but definite pollinose spot on the upper sternopleuron and with a boldly 
marked white pollinose spot on mesopleuron which does not strongly shift with the 
light direction. Upper occiput either metallic or non-metallic adjacent to postocu- 
lar setulae. ¢ frons at narrowest 0-12—0-13 of head-width : 6
