This prettily marked species will be easily recognized by its nume¬ 
rous peculiarities. 
Conicera bicolor n. sp. 
Female. Lenght 2 mm. Black, the last three abdominal segments 
bright orange yellow. Front sub-shining, a little higher than wide; ante¬ 
rior pair of bristles close together, reclinate ; those of next row above 
forming an inverted trapezoid, the middle pair being far in front of the 
lateral ones ; two upper rows only slightly curved. Ocelli placed on an 
elevated tubercle ; no median frontal groove. Antennæ oval, testaceous, 
With a distinct apical angle where the arista is inserted; arista pubescent, 
Palpi small, cylindrical, yeilowish, beset with strong bristles. Proboscis 
very short, brownish. Cheeks without macrochætæ ; post-ocular cilia weak. 
Dorsum of thorax dull black, with one pair of dorsocentral macrochætæ 
and two pairs of marginal scutellar bristles, the outer pair much the 
weaker. Abdomen longer than usual ; dull black, except the three apical 
segments (5th to 7th) which are bright orange yellow ; tip with a few 
black hairs. Legs short and slender; piceous brown. Anterior tibiæ finely 
setulose ; middle pair with an external pair of bristles at the basal third 
and a single sub-apical one, inwardly with a number of transverse comb 
like rows of hairs apically ; posterior tibiæ with a pair at basal third, 
one at apical third and a single sub-apical one. Wings clear hyaline, veins 
dark ; costal vein reaching to distinctly beyond the middle of the wing ; 
its cilia fine and short; first vein ending about halfway from humeral 
cross-vein to tip of third ; discal veins weak ; fourth curved at base, straight 
at apex ; seventh obsolete. Halteres piceous, paler at base. 
Described from one female specimen from Singapore, Malay Pen¬ 
insula (Biró, 1898). 
This pretty species is easily distinguished by the peculiar contrasting 
colors of the abdomen.
