A. E. Verrill — The Bermuda Islands. 



been introduced into Bermuda from Madeira, for oranges and grow- 

 ing plants of various kinds have been brought from there to Ber- 

 muda. 



Mr. J. B. Heyl, in a communication published in Insect Life (vol. 

 iv, p. 267, 1892), states that this insect was introduced after 1859, 

 having been previously unknown, and that the peaches wei - e before 

 that delicious, but the fly maggots soon ruined all the peaches and 

 also attacked mangoes, loquats, etc. 



In a recent letter to the writer, Mr. Geo. A. Bishop, superinten- 

 dent of the Public Garden, states that not only the peaches, but also 

 oranges, figs, avocado pears, sapodillas, anonas, peppers, loquats, 

 Surinam cherries, etc., are attacked by the pest, many of them being 

 so filled with the maggots as to be worthless. 



The prompt destruction of all infested fruit, as soon as it falls, is 

 the chief remedy now available. It passes the pupa state under the 

 surface of the ground, transforming from larva to adult fly in about 

 two weeks in spring — probably sooner in summer. Doubtless it has 

 several broods and attacks other fruits, after the peaches are gone. 

 The fly is yellowish, with dusky or blackish markings ; the male has 

 a pair of spatula-shaped hairs on the front of the head.

This small ortalid fly was recorded by Jones, 187<J. In the United 

 States its larva has been observed to injure sugar-cane, corn, oats, 

 wheat, etc., by burrowing in the stalks, many often occurring in one 

 stalk, causing it to wither and die. According to Fyles the larva 

 sometimes destroys other larvae. The fly is glossy greenish black; 

 wings crossed by two wide bands and a terminal patch of blackish. 

 the bands uniting along the posterior border. Head white ; eyes 

 dark brown; legs yellow. Expanse about 10 mm .
