Campbell. — Notes on the Blepharoceridae of New Zealand. 261 



A single hair arises from each angle of the hexagons (fig. 65). Labrum and 

 hypopharynx as in fig. B. Internally the labrum bears strong single, double, 

 and triple spines turned back from the point of the strong beak. This 

 seems to suggest that our Blepharocerids may prey on other insects, otherwise 

 this armature seems unnecessary (fig. 70). Mandibles present in 9 (fig 69), 

 absent in #. Maxillae present in 3 (fig. 64), absent in 9 (figs. 69 and 74). 

 Labium (fig. 57) long, geniculate, divaricate. Antennae (figs. 62, 71, and 72) 

 usually 14-jointed. Palpi (figs. 63 and 73) short, 2-jointed. 



Thorax of normal form for the family, microscopically pubescent, with 

 a definite chaetotaxy. Halteres long-stalked. 



Legs (fig. 83) : Relative dimensions and characters as in P. turrifer, 

 two spurs on tibiae of hind legs, claws simple, empodium rudimentary. 

 The colour-scheme is black, with a silvery-grey appearance, probably due 

 to light-effects. Slight orange colour near the humeral knobs and wing- 

 bases, legs lighter in colour on the trochanters and bases of the femora. 



Wings (fig. 47) ground-glassy in appearance with dark veins, anal angle 

 obtuse as in Curupira, membrane covered with fine microtrichia. Costa 

 covered with strong macrotrichia, as many as 9 in the rows, corresponding 

 to the primitive veinlets. From the margin of the wing just beyond R 3

fine cilia continue round the wing to the base. The cilia increase in length 

 as they approach the angle. Reduced Sc is more strongly marked than in 

 the other three flies. Some of the bases of insertion of the macrotrichia 

 still carry the spines. Rj^ is a simple vein; R2+3 forms a fork; both R 2 

 and R 3 turn upward near the margin. M fuses with the angle of R4+5, 

 picking up the original r^m in the fusion. Cu x arises as a strong vein, 

 fuses with the persistent fourth branch of M, forming a fork. The last 

 vein is 1A or 2A. Here again I have taken the wing of Edivardsina 

 chilensis (Alexander) as an indication of the lines of reduction. All four 

 wings show the signs of reduction, making an interesting series, which may 

 be clearly seen in the region of R4+5, and to which I have referred 

 previously in regard to the persistent bases of the macrotrichia. 



Abdomen (figs. 86 and 87) : $ with the characteristic laterally com- 

 pressed and turned-up appearance ; 9 larger, round, and tapering. Body- 

 segments with scattered bristles, more numerous near the margins of 

 the segments. Ventrally on each segment are three groups of bristles
