Paralimnophora indistincta. sji. nov. 



One speeimen ilitt'ers so e(»nsideral:)ly from the rest tliat, in default of more 

 material, whicli might show intermediate forms, it seems best to treat it as a distinct 

 species. 



Similar in size, form, and main characters to the last species, but differs as 

 follows : — 



Colour. — All blue-grey, with the face and cheeks silvery. The abdominal spots 

 are practically invisible, being only seen as a slight darkening of the surface on looking 

 sideways. 



Wings, Icij-s. &c.. as last species, except that the thickened part of the 6th vein 

 is proporti(jnally shorter. 



The achrostical bristles between the dorso-central ones are sparer than in the 

 last species, and are roughly arranged in two rows. 



Hab. — Enderby Island. 



Type. — Ca mbridge Museum. 



Melaxochila. Rondani. Aft. Soc. Ital. Milano. ix, 72, 136 (1866). 



Three specimens of an Anthomyiid from Carnley Harbour seem best placed in 

 this genus. They agree well in character with the European species M. riparia, 

 but the head is not quite so much excavated under the antennae, which are conse- 

 quently not quite so porrect as in that species. The specimens having been preserved 

 in spirit may account for some alteration in form. 



Melanochila insularis, sp. nov. 



Size. — About 4 mm. 



Head. — Frons brown-grey, with darker eye-margins and ocellar area. Face 

 lifdrter grey ; jowls with the front part light grey, the back part brown. Back of 

 head grey. Palpi yellow, darkened at the ends. Antennae dark grey, the 3rd joint 

 moderately pointed. 



Thorax. — Brown-grey, with 2 narrow greyer stripes more evident in fi-ont. 

 Pleurae lighter grey. ScuteUuni with a small light-grey spot on each side at the 

 base. 



Wings. — Slightly suffused with brown ; the unequal moderately sized squarime 

 with orange edges. Halteres orange. 



Legs. — Femora dark grey, knees and tibiae orange ; tarsal joints getting darker 

 towards the last 2, which are black.
