 a. Wings unspotted. 



Macrocera montana, sp. nov. Plate VIII., fig. 3. 



Length of antennae, 0-247; size of body, 0-215 x 0-038; 

 expanse of wing, 0-161x0-084. 



Antennae considerably longer than the body ; joints of 

 scapus short, dark-brown ; lower joints of flagellum dark- 

 yellow with black tips, clothed with scattered black hairs ; 

 last six or seven joints dark-brown to black, clothed with 

 much longer hairs. Front brown. Thorax bright - yellow, 

 slightly darker on tlie median line ; on each side of it there is 

 a line of stiff black hairs which taper towards one another, 

 but do not coalesce ; lateral margins of thorax bordered 

 with long stifl' black hairs. Pleura black. Scutellum fringed 

 with a border of long stiff black han-s. Metathorax black 

 with yellow sides. Abdomen very slender, compressed ; each 

 segment with anterior portion yellowish -brown, becoming 

 dark - brown posteriorly, clothed with long scattered black

 the body, dull-yellow, with a microscopic pubescence. Veins 

 umber-brown, with a row of black hairs on each ; auxiliary 

 vein joining the costa beyond the origin of the cross-vein ; tip 

 of first longitudinal vein not dilated ; costal vein reaching 

 the apex of the wing; inner marginal cell w^ith a very pointed 

 apex. 



I have only one specimen of this insect, which was taken 

 in a shady, damp gully on the Eimutaka Mountains, at an 

 elevation of about 2,000ft. It is rather closely allied to M. 

 delicata, Skuse, of New South Wales.

 yellowy very short ; basal joint of flagellum dark - brown, 

 densely clothed with short black hairs ; all other joints much 

 lighter in colour, central joints lightest ; last five joints 

 covered with moderately-long bristly hairs. Ocelli situated in 

 a triangular black spot, but all the rest of the head is light-
