median bristle; hind femur with one preapical antero- 

 ventral bristle ; hind tibia with one antero-veutral and one 

 antero-dorsal bristle^ the postero-dorsal surface sometimes 

 with a weak setula. Outer cross-vein straight. Lower 

 calyptra not much larger than upper. 



Length 5-6*5 mm. 



'^yp^i Wangauui, New Zealand, 20. iii. 1920. Paratype, 

 topotypical. 



Subfamily C(enosiin^. 

 Pygophora minuta, sp. n. 



Male. — Black, densely pale grey pruinescent. Inter- 

 frontalia pale yellowish testaceous ; antennae yellowish, 

 third segment brown except at base ; palpi yellow. Thorax 

 not vittate. Abdomen black, basal tergite except in middle, 

 apices of tergites 2 and 3, sides of all tergites, hypopygium, 

 and entire venter yellowish testaceous. Legs entirely yellow. 

 Calyptrse and halteres yellowish. Wings clear, veins pale. 



Frons at vertex about one-fifth of the head-Avidtli, widened 

 anteriorly ; each orbit with the normal four bristles, the 

 upper one very weak, the next two not so closely placed as 

 in the genotype ; third autennal segment extending almost 

 to mouth-margin, about three times as long as second; 

 arista plumose at base, bare apically. Thoracic chaetotaxy 

 normal. Abdomen compressed apically ; third, fourth, and 

 fifth tergites each with a number of flattened bristles 

 resembling minute feathers on sides, those on fourth much 

 larger than on third and fifth ; processes of fifth sternite 

 bare, longer than wide and but little dilated at apices ; the 

 processes at base of excavation very short, barely stalked. 

 Antero-dorsal bristles on fore tibia very short and weak ; 

 all tibial bristles as in genotype, but much weaker. Last 

 section of fourth wing-vein nearly twice as long as 

 penultimate. 



Length 8'5 mm. 



Type, Kuranda, North Queensland, 21. vi.-24. viii. 1913, 

 1100 feet (R. E. Turner). 



This species is the smallest of the genus known to me. 

 It has no protuberance at apex of hind tibia on ventral 

 surface, but is a true Pygophora, and may be separated 

 from its allies by the peculiar flat bristles on sides of the 

 abdomen.
