tion continues with unremitted perseverance on 
the part of one or other of the respective races of 
the Flies. 
Of the hairy Flies with bristled antennas, the 
Musca grossa, the largest of all the European 
Flies, affords a good example. It is considerably 
larger than the largest blow-fly, and is of a black 
colour, with the wings dull orange-coloured at 
their base. In its general appearance it greatly 
resembles the Musca meridiana, which is similar 
in colours, but stands in a different division in the 
genus, viz. among the hairy flies with plumed 
antennas. 
Musca jiava is one of the smallest but most ele- 
gant of the European flies, and is not very un- 
common during the autumnal season, being ob- 
served in gardens and in windows. It is about 
the eighth part of an inch in length, and of a 
yellow colour with bright gold-green eyes.
