This is a strange little tachinid with a fluffy thorax (the hair has been matted by alcohol in the photos) similar to Pollenia (Calliphoridae). It also has extremely large Carcelia-like eyes and narrow gena. The proboscis is also quite long and looks like it might project slightly in front of the mouth edge if it could be located in its normal resting position.
EDIT (Monty Wood 26/9/2010): These are Telothyria spp. – a very distinctive genus with branched hairs on the pleurae – similar in texture to bee hairs.
