 Hah. Auckland (Dr. Sinclair) ; Wellington (Hudson). 

 This species is a true Nemoraa, and is closely related to 

 N. rubnca, of Europe. Walker's statement that the abdo- 

 men is narrow and nearly cylindrical must be a mistake, as 

 the rest of his description corresponds very well with two 

 specimens from Wellington, provided w T e interpret " inter- 

 rupted black stripe" to mean that it does not reach the apex 

 of the abdomen. 



Genus Hystricia, Macquart (1843). 



Front moderately broad ; the epistome salient. Antennae 

 not reaching the epistome ; the second joint rather elongated, 

 the third usually double the second ; straight before and be- 

 hind ; arista minutely pubescent, the second joint elongated. 

 Eyes large, hairy. Abdomen broader than the thorax, pro- 

 vided with strong bristles. First posterior cell slightly open, 

 ending much before the tip of the wing. 



Hystricia lupina.

Tachina zelica, Walker, Cat. Dipt, in Brit. Mus., p. 711

Abdomen bright-tawny, the hind border of each segment 

 black. Length, 18 mm. ; wing, 16 mm.
