159. P/ioi a cleff/iomi Bigot (Muscidse). — A minute fly, said to destroy 

 the larv0B of the silk-worm Tachinid [Trycolyga homhycis), which it attacks 

 much in the way that the Tachinid attacks the silk caterpillar. 



160. Anthomyia PESHAWARENSis Bigot (Muscidise). Parasitic upon 

 the eggs of the locust Acridium peregriuum. It is believed to have a 

 considerable effect in keeping down the numbers of this locust in India. 

 In appearance it is not unlike a very small house fly. 



161. Oscinis thea Bigot (Muscidse), The grubs of this minute fly 

 are said to tunnel into the leaves of tea [Camellia theifera) bushes in 

 Ceylon. They are not thought to do any appreciable damage. 



162. DrosopMla apicata Bigot (Muscidse). — The grubs of this minute 

 fly are said to attack the fruit of the grape vine [Vitis vmifera) in Bashahr. 



163. Anthomyza coffem Nietner ( = A. coffeifolia Motsch). — The 

 grubs of this fly are said to mine the leaves of coffee [Coffea arahicd) 

 bushes in Ceylon, where however they are not very common (Nietner). 

 The insect is one of the Muscidse. 



164. Dacus ferrngineus Fabr. (Muscidee.) — The grubs of this fly 

 have been reported as doing considerable damage to mangoes [Mangi- 



fera indica) in Mozufferpore. When full grown, they are about the size 

 of grains of boiled rice, and are to be found in the pulp of the fruit 

 attacked by them.

 been reported as seriously interfering with the growth of peach [Prunus 

 persica) fruit in Chota Nagpur. 



166. Carpomyia parctalina Bigot (Muscidse). — This fly has been 

 reported as most injurious to melon [Cucurbitacece] cultivation in Balu- 

 chistan. Larvse also, which may perhaps belong to the same species, have 

 been reported as destructive to gourds (Cucurbitacese) in Berhampore. 

 The grubs bore into the fruit and cause it to rot. 



Rhynchota. 



167. Canthecona furcellafa Wolff. (Pentatomidse). — A small active 

 yellowish insect, reported to destroy tusser silk-worms {Antheraa my- 

 litta), and likely also to help in keeping down the numbers of defo- 

 liating caterpillars. It is armed with a proboscis with which it trans-
