Calcager temerarium, sp. nov. 



Head greyish-white, with a central band of dark-brown on 

 the front, which is sometimes covered with white tomentum. 

 Face and epistome tawny, with scattered white tomentum. 

 Antennae reddish-brown, the first and second joints with pale 

 tomentum. Proboscis brown, palpi pale -tawny. Thorax 

 greyish-brown, with four interrupted dark-brown stripes, the 

 inner pair narrower than the outer. Scutellum greyish- 

 brown. Abdomen greyish-brown, without spots. Legs tes- 

 taceous, the tarsi black. Squamae brow T nish-white. Wings 

 spotless, the larger veins tawny. The fourth longitudinal is 

 bent in a curve nearly to a right angle and meets the third 

 at the tip. The posterior cross-vein is at right angles to 

 the longitudinal, and is distinctly sinuated. Length, 7 mm. ; 

 wing, 5 mm. 



Hab. Christchurch (F. W. H.). 



The third joint of the antennae is nearly one and a half 

 times the length of the second ; its anterior margin is concave 

 and its posterior margin convex. The second joint of the 

 arista is about one-third of the third joint. The facial ridges 

 are bare. The eyes have a few hairs. The setae on the third 

 longitudinal are few, and placed at its junction with the second 

 longitudinal. The costal seta is well marked. The second 

 and third abdominal segments have one pair of discal setae. 



Calcager humeratum, sp. nov. 



Head tawny, passing into brown on the front. First and 

 second joints of the antennae reddish-brown, the third almost 

 black ; palpi tawny. Eyes rather small, dark-brown, bare. 

 Thorax blackish- brown, the shoulders and a band on each 

 side, above the wing, tawny ; apex of the scutellum tawny. 

 Abdomen black, tessellated with grey tomentum. Legs 

 tawny, the tarsi black. Squamae and wings pale-brown, the 

 veins dark-brown. Bend of the fourth longitudinal obtuse ; 

 posterior cross-vein at right angles to the longitudinals, but 

 much sinuated. Bristles on the body and legs weak ; very few 

 on the abdomen. Length, 8mm. ; wing, 7 mm. 



Hab. Wellington (Hudson). 



The front is prominent and longitudinally grooved ; the 

 eyes are rather small, and the face projecting. The second 

 joint of the antennae is not much elongated, while the third is 

 nearly twice as long. The second joint of the arista also is 

 rather short, being about one-seventh of the length of the 

 third joint. It connects Calcagcr with Proscissio. 



Genus NEMOBiEA, B. Desvoidy (1830). 

 Large. Eyes hairy, more or less approximated in the 

 male, always much shorter than the sides of the head ; fore-
