Hab. Dunedin and Christchurch (F. W. H.). Eare. 



The fourth longitudinal vein is strongly arched after the 

 bend. The antennae are rather short, the third joint being 

 not more than twice the length of the second. The hairs on 

 the arista are also short. 



Calliphora lsemica. 



Musca Imnica, White, in Dieffenbach's " New Zealand," 

 vol. ii., p. 291 (1843); Yoy. "Erebus" and "Terror," 

 Insects, pi. 7, fig. 18: Walker, Cat. Dipt, in Brit. Mus., 

 p. 906 (1849). Sarcophaga lamica, Hudson, Man. N.Z. 

 Ent., p. 61, pi. vii., fig. 10. 



Vertex dark-brown ; cheeks yellowish-white, with brown 

 marks; lower face tawny, with golden hairs. First and second 

 joints of the antennas ferruginous ; the third piceous, four 

 times as long as the second. Eyes bare, contiguous in the 

 male. Thorax dark-grey, with black longitudinal bands above, 

 fulvous below. Abdomen fulvous, with bronzy reflections, 

 with yellow hairs on the sides and below. Legs tawny or 

 ferruginous, the tarsi darker. Length, 7-12 mm. 



Hab. Throughout New Zealand. Probably introduced 

 from Australia, where it is also found, as well as in Polynesia. 



This species has been abundant in the North Island for a 

 long time, and it extended as far south as Christchurch in 

 1874, but it was not common. I never found it in Otago up 

 to 1879, when I was living there, but this year (1900) I saw 

 it at Queenstown. It thus appears to have come down from 

 the North. Walker considered it to belong to Pollenia, to 

 which genus it should, perhaps, be referred. 



Genus Sepimentum, gen. nov. 



Eyes bare, subcontiguous in the male, a pair of orbital 

 bristles on each side in the female. Antennas rather short, 

 not reaching the epistome ; third joint about three times the 

 length of the second ; arista plumose on both sides, the tip 

 sometimes bare, especially in the female. Outer and lower 

 cheeks hairy. Facial ridges with some hairs on the lower 

 fourth. Epistome slightly projecting. Thorax with six rows 

 of dorso-central bristles. Abdomen without either discal or 

 marginal macrochastae. Tibiae with one or two bristles on the 

 inner side. Fourth longitudinal vein curving round at an 

 obtuse angle and then straight ; first posterior cell generally 

 closed, sometimes shortly petiolate, sometimes very narrowly 

 open. Posterior cross-vein sinuated. 



This genus differs from Pollenia in the thorax and ab- 

 domen not being thickly set with short hairs, and from Calli- 

 phora by the direction of the fourth longitudinal vein, as well 

 as by the closed apical cell.
