219 Indian Museum Notes* [Vol. IV. 



" (ix) Anthomyia peshaisoarensis^ Bigot, parasitic upon the eggs of the locusts 

 {Acridium peregrinum) in India. 



"(x) i/rti^Veffl 5M6?i?V^a, Wulp., parasitic upon the larvsB of the moth Oletie 

 mendosa, Hubn., which attack tea plants in Darjeeling. 



" (xi) Masicera castanea, Wulp,, said to prey upon caterpillars of the moth 

 Leucania extranea, Guen., which attack the young paddy plants in Bengal. 



" (xii) Masicera dasychirce, Wulp., parasitic upon caterpillars of the moth 

 Dasychira thwaitesii which does much damage to tea plant and sal tree in 

 Assam. 



" (xiii-xiv) Demoticus strigipennis, Wulp., and Calodexia lasiocampcB, Wulp. 

 The larvae of these two flies are parasitic upon a hairy Lasiocampid caterpillar 

 destructive to rice in the Central Provinces. 



" (xv) Miltogramma i2-punctafa, Wulp., which preys upon the locust 

 {Acridium pere§rinum) in India. 



III.— SOME HYMENOPTERA (FAMILY CHALCIDID^) KNOWN TO BE 

 DESTRUCTIVE TO INSECT-PESTS. 



" (xvi) Chalets {Bra chymeria) euplisa, Westw., preys upon the Dooars tea 

 and sal caterpillar {Dasychira ihixiaitesii). 



" (xvii) Cotesia flavipes, Cameron, parasitic upon the Sorghum-borer {Diatrcea 

 saccharalis). 



" (xviii) Aphelinus thece, Cameron, a minute fly-like insect that attacks the tea 

 scale bug {Chionaspis thece, Mask). 



" (xix-xxvi) Cirrhospilus coccivorus, Motsch., Encyrtus nietneri, Motsch. 

 E. parodisicus, Motsch., Scutellisfa cyanea, Motsch., Marietta leopardina, 

 Nietner, Cephaleta purpureiventris, Motsch., C. bunneiventris, Motsch., and 

 C. fusciventris, Motsch., are said to be parasitic upon the Brown bug {Lecanium 

 coffees) of coffee plant in Ceylon. 



" (xxvii) Chartocerus musciformis, Motsch., said to attack the white bug 

 {Pseudococcus adonidum) of coffee plant in Ceylon. 



" (xxviii) Pteromalus oryzce, Cameron, a minute coppery green-coloured 

 Ichneumon-fly beHeved to be parasitic upon the wheat and rice weevil {Calandra 

 oryzce) in India." 



The above are some of the indigenous species of insect-parasites 

 of insect-pests that have come to light without any special inquiry, 

 and no doubt systematic research (which certainly ought at some 

 day to be undertaken), would reveal many more. In the face of 

 Mr. Barlow's report it can hardly be hoped that the introduction of 

 a single foreign species of Lady-bird — even if that species be able 

 to hold its own against the native species—will have any very 

 marked effect.
