N.B. — Theobald says that his figure of the pupa (Monog. 

 Culic, iii, 123, fig. 67) is not quite correct. He also describes 

 the 9 (Rec. Ind. Mus., iv, 4), and says that the type ( cf ) in the 

 British Mus. is in bad condition. 



Mr, E. E. Green gives the Hfe- history (with a plate) of this 

 species (Spol. Zeyl., ii, pt. viii, 159 to 164) (1905). He says the 

 larvae prey first on those of their own race before proceeding to 

 devour those of other species, and that he does not know of the 

 adult biting. Females were kept alive for eleven days on sliced 

 ba lianas. 



Mr. C. A. Paiva gives a very interesting account of the habits 

 of the larva (Rec. Ind. Mus., v, 187) from personal observations 

 and experiments. It is common in the outskirts of Calcutta during 

 June and July in earthen pots. He finds that the larva will 

 devour that of any other species if present before attacking those 

 of its own kind, whereas Mr. E. E. Green thought it ate its own 

 species first. They are sluggish and remain at the surface of the 

 water, seizing other larvae as they come within reach. A curious 

 thing is that the larvae of other species actually attack the 

 immisericors larvae, seizing their abdominal bristles from behind. 

 Stegomyia fasciata the carrier of yellow fever is greedily devoured 

 by T. immisericors larva, which renders it a valuable ally in 

 destroying the former in the event of that disease being introduced 

 into India, the more so as the adult is not known to bite man. 



N.B. — Megarhinus gilesii, Theob., and subulifer, DoL, to be 

 eliminated from synonymy, as both are now regarded as good 

 species belonging to Toxorhynchites.
