1922] Alexander: Cra7ie-Flies from New Zealand 225 



veins dark brown. Venation: Sc long, Sc\ ending just beyond mid- 

 length of Rs, Sc2 near mid-distance between the origin of Rs and the 

 tip of Sc] ; Rs long, provided with seven macrotrichije ; r very long and 

 strongly arcuated, longer than the basal deflection of Cui, located at 

 the tip of i^i; deflection of T^j+s angulated and spurred; cell 1st if 2 long 

 and narrow; basal deflection of Cuy at midlength of cell 1st M^. 



Abdominal tergites yellowish brown the sternites a little darker 

 with the incisures narrowly and indistinctly pale. Ovipositor with 

 elongate valves. 



Hab. New Zealand (South Island). Holotype, 9 Mt. Grey, 

 Canterbury, November, 1916 (/. W. Campbell). Paratypes 

 9 ? , Ben Lomond Otago, December 30, 1921, January 2, 1922, 

 (Geo. Howes). 



Amphineurus senex, sp n. 



General coloration brown; wings and legs un variegated ; 

 Rs square at origin; i?2+5 short but evident; cell 1st M^ closed. 

 Male. — Length 4.3 mm.; wing 5.5 mm. 



Rostrum and palpi dark brown. Antennae with the scapal segments 

 dark brown; flagellar segments obscure yellow, with conspicuous erect, 

 black verticils. Head greyish ochraceous, the vertex with very con- 

 spicuous, light yellow, scale-like hairs. 



Mesonotal prsescutum greyish ochraceous with two narrow dark 

 brown intermediate stripes, very narrowly and indistinctly separated 

 by a capillary pale line; lateral stripes not indicated; pseudo-sutural 

 fovccB very conspicuous, elongate, lying transversely, dark brown; 

 tuberculate pits lying a little cephalad of the level of the foveas, pale, 

 one on either side of the capillary pale line; remainder of mesonotum 

 light brown. Pleura light brownish grey variegated with darker brown; 

 a group of conspicuous yellow hairs beneath the wing-root. Halteres 

 yellow, the stem, except the base, densely clothed with appressed, 

 dusky scale-like hairs; apex of knobs yellowish. Legs with the coxae 

 and trochanters obscure yellow, the former clothed with yellow scale- 

 like hairs; remainder of the legs dark brown. Wings greyish subhy- 

 aline, the veins and membrane densely clothed with brown macrotrichi^e 

 to almost completely conceal the coloration; veins pale brown. Vena- 

 tion: Rs almost square at origin, feebly spurred; 7?2+3 short, about 

 equal to the deflection of i^i+s; r on R2 about twice its length beyond 

 the fork; cell 1st M2 closed, long and narrow, gradually widened dis- 

 tally; m nearly three times as long as the outer deflection of M3; basal 

 deflection of Cui just before the fork of M. 



Abdomen dark brown, clothed with yellow hairs. • Male hypopygium 

 with the apices of the pleurites long-drawn-out, contiguous at their 

 tips; the forceps at base of pleurites slender, acicular, curved, clothed 

 on the inner face with pale erect hairs; second pair of forceps larger, 

 black, compressed, the tips slender, curved and directed laterad.
