Alexander — Crane Flies 233 



these two veins being in oblique alignment ; R^ projecting beyond r, the tip 

 atrophied; a supernumerary eross-vein in cell Se^ about its own length before r; 

 veins beyond the eord long and parallel; m a little longer than the outer 

 defleetion of M^, slightly arcuated ; basal deflection of Cu^ beyond midlength of 

 cell first M-. Abdomen dark brown. Ovipositor with the valves small and 

 slender, reddish horn-colour. 



Hah. Queensland: Cairns district (A. M. Lea). Type I. 12143. 



L. ohliqua is closely allied to L. nervosa de Meijere, from which it differs in 

 the different pattern of the wings and the venation, especially the longer Sc, Rs, 

 and cell first M^. 



LIBNOTES HOWENSIS sp. nov. 



General colouration yellow, the mesonotum grey-pruinose ; pleura striped 

 longitudinally with dark brown lines ; femora with a narrow dark brown sub- 

 terminal ring; wings light yellow, very sparselj^ and indistinctly marked with 

 brown. 



S Length, about 15 mm.; wing, 17-2 mm. Middle leg, femur, 14-7 mm.; 

 tibia, 13-5 mm.; tarsus, 11-5 mm. 



Rostrum moderately elongate, yellow; palpi short, dark brown. Antennae 

 with the elongate basal segment dusted with grey ; second segment dark brown ; 

 flagellar segments yellow, the distal segments gradually infuscated ; basal flagellar 

 segments oval, the terminal segments more elongated. Head light cream colour. 

 Vertex between eyes very narrow. Mesonotal praescutum light grey, very 

 indistinctly marked with darker grey; scutum whitish grey, the centres of the 

 lobes darker grey ; remainder of the mesonotum whitish-pollinose. Pleura 

 whitish-pollinose, narrowly lined with longitudinal dark broAvn stripes; the mor'^ 

 dorsal of these lies behind the wing-root on the lateral sclerite of the postnotum ; 

 a .second stripe begins above the fore coxa, traversing the mesepisternum and 

 mesepimeron, becoming obsolete near the halteres. Halteres yellow, the knobs 

 broAvn. Legs with the coxae yelloM^ ; a dark brown spot on the outer face of the 

 fore coxa; femora yellow, the tips almost whitish; a narrow (about 0-9 mm..) 

 subterminal brown ring; tibiae yellow, the tips narrowly darkened; basal two 

 tarsal segments j^ellow, the tips narrowly darkened ; terminal three tarsal seg- 

 ments black. Wings light yellow; stigma indistinct; very faint brown spots at 

 the origin of Rs ; fork of M ; at the basal deflection of Cu^ ; at m and the tips of 

 veins Cu^, first A and second A, larger and more conspicuous on the latter ; veins 

 yellow, darker in the infuscated areas. Venation: Rs almost straight, in align- 

 ment with R*+^ ; r at the tip of R^ ; cell first M- long and narrow ; m nearly as 

 long as Rs; basal deflection of Cu^ at about one-fifth the length of the long cell
