170 AUSTRALIAN BLEPHAROCERIDAE, 



fig. 3, c.) with a very short, slender and slightly curved black palpus, consisting 

 of a single segment, and carrying a few hairs, and with a slender, pale coloured 

 and sharply pointed galea, twice as long as the palp. Labium (Text -fig. 2, 

 e, f.) very long and slender, black, projecting downwards and backwards more 

 than twice the whole diameter of the head; labellum with basal segments closely 

 approximated and connected by membrane, the distal segments diverging widely 

 and with the distal portions curving outwards, more so in 2 than in <3. 



Thorax velvety black, with silvery-grey markings similar to those shown 

 in Text-fig. 7 for the female, but less conspicuous and narrower; suture between 

 mesonotum and mesopleura more widely marked in the same colour; scutellum 

 black, convexly rounded. 



Legs : — Fore and middle legs rather short, the middle shorter than the fore, 

 hind very long. Coxae and trochanters short,, silvery grey pubescent ; femora, 

 tibiae and tarsi long, black ; distal halves of fore and middle femora somewhat 

 swollen, those of hind femora only slightly so. Measurements as follows : — 



Foreleg: — Femur 1.5, tibia 2.3, tarsus 2.8 mm. 



Middle leg : — Femur 1.5, tibia 1.7, tarsus 1.7 mm. 



Hind leg : — Femur 4.5, tibia 4.5, tarsus 4 mm. 



Hind tibia (Plate xlv., fig. 5, c.) with two equal black spurs. Hind tarsus 

 (Plate xlv., fig. 6, c. ) with the segments very long and slender, narrowly cylindrical, 

 1 nearly twice as long as 2; order of length of segments 1, 2, 3, 4 = 5. Inner 

 margin of 1 bears about ten small spines, that of 2 four similar spines, and 

 that of 3 and 4 one each. Tarsal claws (Plate xlv., fig. 7, c. ) curved, black, sharply 

 pointed, carrying on inner side about eight strong teeth, all set closely together 

 on basal two-thirds. Empodium well developed, slender, about one-third as long 

 as claw. 



Wings: — Forewing (Text-fig. 1, c.) hyaline without the slightest infuseation; 

 C and Ri stout, jet black, forming a very strong anterior border to the wing; 

 venation black. Venation and secondary net-veining as shown in Text-fig. 1, c. 

 The venation differs from that of other members of the genus in having the short 

 stalk of Rs from R to r-m obliterated, while r-m itself runs from M forwards as 

 a strong oblique vein ending anteriorly on R, just before the apparent origin of 

 Rs. Distal curvature of Rs (typical of the genus) well marked. About three 

 fourths of the way along Mi +2 there is always a very slight but more or less 

 clearly marked kink (k), indicating the point where M2 originally came off. The 

 point a; marks the secondary origin of M4 from Cui, brought about by the sup- 

 pression of the original basal piece of M3+4 and its union with m-cu; this point 

 is situated only very slightly distad from the level of the axillary lobe. 1A fails 

 to meet the wing-margin. The secondary net-veining is on the same general plan 

 as that of Neocurupira and Peritheaies, but very different from that of Edward- 

 sina. Halteres 1 mm. long, with blackish swollen base, slender brownish pedicel, 

 and black spatulate club. 



Abdomen slender cylindrical, hairless, velvety black; seg. 1 wtih a trans- 

 verse band of silver, complete, but very narrow mid-dorsally ; 2-5 with conspicuous 

 basal lateral silvery spots, not connected across the dorsum, rest black ; sides of 

 abdomen covered with silvery grey pubescence, underside brownish. Hi/popygium, 

 upturned, shaped as shown in Text-fig. 6, a, b, the superior processes and forceps 

 black and hairy. 



? slightly larger than <J, forewing 6.5, expanse 14. hindleg 14 mm. 



Differs from the c? as follows: — Head smaller (Text-fig. 2, /.), the eyes dull 

 blackish, dichoptic, separated above by a space as broad as their combined 

 widths; eyes divided transversely by a non-facetted line which cuts off a very 

 small upper and very large lower portion; oeellar tubercle larger than in d; a
