Diptera, as a whole, has a very slight faunistic value, and as 

 bearing further upon the modern extraordinary distribution of 

 species by the agency of commerce. Among the nineteen spe 

 cies only four were new, and one other seemed to be peculiar to 

 Hawaii. Ten of the species were practically cosmopolitan ; one 

 had previously been found in Australia ; one had a general dis 

 tribution in Oceanica, and one had been known previously only 

 from Keeling Island, near Sumatra. The full list of these Diptera 

 is as follows :
