of the posterior cross-vein, which is about three-quarters of 

 its own length from the margin. Length, 3i mm. ; wing, 

 3 mm. 



Hab. Auckland Islands. 



Milichia littorea, sp. nov. 



Brown ; sides of the face, ocellar triangle, and four stripes

 in the middle, four in a row. Halteres fulvous. Wings fus- 

 cous, with pale spots, three in the submarginal cell, two in 

 the first posterior cell, one in the second posterior, and one in 

 the discal cell. The costal, exterior part of marginal, and 

 first basal cells are clear. There are three distinct basal cells. 

 Veins verv dark-brown. No incision on the costa before the 

 tip of the first longitudinal vein. Posterior cross-vein present, 

 situated nearly in the middle of the wing ; not much more 

 than its own length from the margin. The distance between 

 the cross- veins is quite twice the length of the posterior cross-

 the margin. Length, 2 mm. ; wing, 2 mm.
