Walker has Jc^scribed two .species under this name, but the 

 one described in Dipt. Saund. is not to be identified. The 

 type is old and iK-nu led of Jiairs. Walker's dcscrij)tion may 

 be anuMidc(l thus, from modern s|)i'cimens : — 



AnteiuKO brii;ht red, the first and second Joints feriuf^inous, 

 with black hairs. Face has a i)lack square mark above the 

 palpi ; these latter are long and slender. Proboscis is short. 

 Thorax with tawny hairs on sides, extending also to the 

 scntellum. There are tufts of white hairs on the middle of 

 the posterior borders of the first four segments of abdomen, 

 thickest on the third ami fourth ; the hiuil segments incline 

 to a reddish colour. Wings with first and fourth posterior 

 cells closed ; a rudimentary appendix is present on the fork of 

 the third longitudinal vein in only one out of the four female 

 specimens in the ^luseum. 



This s|)ecies should belong to Scione, Walker {DicUaa^ 

 Schiner), having the fourth posterior cell closed, but the head, 

 face, and proboscis do not agree with the description of the 

 genus {Diclisa, Schiner) in ' Reise der Novara,' and it is too 

 nearly allied to the two preceding species to make it advisable 

 to remove it from Krei'hrosis at present.

This was one of the species collected in voyage of * Erebus ' 

 and ' Terror ' and described by White in i\IS. only. Walker 

 described it in Dipt. Saund. as .f\iiigo>u'a adrel, White. 

 Jiutler published AVhite's original description of it, bdieving 

 it had not been published before. A\'liite placed it under 

 Tabanus. Two out of the six male specimens in the Museum 

 have the first posterior cell of wings closed, in all the others it 

 is open ; in the female s|}ecimons it also varies. In the original 

 description there is no nienlion of the wing-cells; Walker says 

 the first posterior cell is closed. \\\ the male the sides of the 

 first two segments of the abdomen arc fulvous; the tufts of 

 white or yellow hair on middle of abdominal segments arc not
