AIakshall. — Oil Neiv Zealand Diptera. 293 



Tout covered with black hairs and a few black spines ; pos- 

 terior tibitfi rather long and stout, with more numerous and 

 longer spines ; all tarsi black, owing to thick covering of 

 black hairs ; spurs yellow at the base, shading to brown at 

 the tip. Wings slightly shaded with brown, and covered 

 with black hairs. Costa and first and second longitudinal 

 veins black, others light-brown ; fifth longitudinal extending 

 some distance beyond fork of fourth, but not reaching the 



'o 



margm. 



I have only one specimen of this insect. It was taken in 

 Fagus bush, at the base of Mount Torlesse, in March. 



Genus Anomala, nov. gen. 



Head moderate, nearly round, but slightly prolonged pos- 

 teriorly, situated rather deep in the thorax. Eyes ovate, 

 entire. Ocelli two, or three : if only two present, one is 

 situated in the margin of each of the compound eyes ; if three, 

 the third in the middle of the front. Palpi short, incurved, 

 four-jointed ; first joint short, moderately robust ; second 

 much longer ; third and fourth more slender and about 

 •equally long. Antennae cylindrical, tapering towards the 

 apex, projecting forwards, arcuated, 2 + 14 jointed ; first 

 joint of scapus nearly cylindrical, second cupuliform, both 

 joints setiferous on the sides and upper edge ; flagellar joints 

 cylindrical, with a short downy pubescence. Thorax highly 

 arched. Scutellum semicircular. Abdomen rather flattened, 

 broadest in the middle. Legs rather short ; tibiae spurred, 

 and provided with lateral spines which are short on the 

 anterior tibiae, and long ones arranged in three ranges on the 

 intermediate and two ranges on the posterior tibiae. Wings 

 with rounded apex and anal angle. Auxiliary vein joining the 

 ■costa just before the origin of the third longitudinal vein ; 

 costal vein extending some distance beyond the tip of the 

 second longitudinal vein; first longitudinal joins the costa 

 before the branch of the third longitudinal vein ; marginal 

 cross-vein situated a little before the tip of the first longitu- 

 dinal, which bends down and closely approaches the second 

 longitudinal ; anterior branch of third longitudinal reaching 

 the margin just before the apex of the wing ; apex of fork of 

 fourth longitudinal situated just before the apex of fork of 

 third longitudinal ; anterior branch straight, posterior branch 

 undulated ; fifth longitudinal indistinct ; subcostal cross-vein 

 absent. 



This genus is closely allied to Leia, Ateleia, Acrodicrania, 

 and Ccelosia, but can be easily distinguished by the absence of 

 the subcostal cross-vein, and by the fact that the third and 

 fourth longitudinal veins are complete.
