Musca antiquissima Walker, Australia. 

 Musca calleva Walker, South Africa. 

 Musca vicaria Walker, New Zealand. 

 Musca pampasiana Bigot, Buenos Ayre?>. 



I have since examined the type of Musca fiavinervis Thomson 

 at Copenhagen, and find it is this species, thus confirming my 

 previous determination. But a reexamination of Bigot's and 

 Walker's types has led to the final conclusion that M. antiquis- 

 sima, calleva, vicaria, and pampasiana are identical with M. 

 domestica L. I was unable to find the types of either Macquart's 

 M. sanctae-helenae, lateralis, basilaris, frontalis, or analis in 

 Paris, and therefore I propose finally deleting these names from 

 the literature, for it is quite impossible to be certain what they 

 are, from Macquart's commonplace descriptions. I have not 

 seen the type of M. consanguinea, but Professor Bezzi tells me 

 it is M. domestica L. I have also not as yet seen the type of 

 Musca biseta Hough, which I believe is in Philadelphia. I 

 have been unable to find out where the type of M. divaricata 

 Awati is, and, unless it is forthcoming, I propose dropping this 

 name later. As M. vicina is the oldest name of this species, the 

 type of which I have seen, I propose adopting this name in 

 future for the species of Musca which is like M. domestica L., 

 but in which the male has a much narrower front. 



Musca vicina is widely distributed in the Tropics, and is a 

 common house fly. The male is easily distinguished from that 

 of M. domestica L., by its narrower front, which is about one- 

 seventh to one-eighth the width of the eye, and about half that 

 of M. domestica. The female is very like that of domestica 

 and difficult to distinguish from it, but the parafacials are 

 a little wider and the frontal stripe is distinctly narrower; the 

 apparent first and second abdominal segments, especially the 

 former, are lighter orange than those of domestica, in which 

 they are usually dark brown or black. One female in the col- 

 lection is indistinguishable from the European domestica, and it 

 is very probable that this species occurs in the Islands. A more 

 extensive collection of house and bazaar flies would be of great 

 interest in this direction.
