The author records the fact that swarms of Anopheles (Cellia) 

 pulcherrimus appeared on a hospital ship, when lying ofi Shatt-el- 

 Arab, 15| miles from the nearest land. Not a single mosquito had 

 been noticed on the voyage from Bombay, and a search revealed no 

 breeding place on board.

 brazileiras do Genero Simulium. Pium do Norte {Simulium 

 amazonicum). [A third Contribution to the Knowledge of the 

 Brazilian Species of the Genus Simulium: S. afnazonicum.] —

This paper re-describes Simulium amazonicimi, Goeldi, of which 

 S. exiguum, Lutz, S. minusculum, Lutz, and S. nitidum, Malloch, are 

 now considered to be synonyms. The females are sometimes very 

 eager for blood and attack man, especially canoe travellers on streams 

 with many cataracts ; in the case of those on horseback, the horse 

 is preferred. *S. amazonicum is sometimes met with in small numbers 

 by night, being attracted by hght. It is widely distributed in the 

 Amazon region in places where there are cataracts and in the basins 

 of the Sao Francisco and Prata Rivers. It breeds in the cataracts, 

 but the adults are able to travel considerable distances. This fact 

 and the large numbers found in certain places indicate that the females 

 are long-lived. On the S. Francisco river the author found many 

 la^rvae and pupae of this species on a plant resembHng Ligea. The 

 pupae, collected at night-fall and kept damp, yielded on the following 

 morning specimens of both sexes.

The author prefaces these notes by stating his agreement with the 

 view that the Oestrinae should be treated as a sub-family of the 



MUSCIDAE. 



A key is given to the genera observed in Brazil together with the 

 following list of South American species : — From French Guiana, 

 Cuterebra ephippium, Latr, From Patagonia, C. patagona, Guer. 

 From South America, C. tnegastoma, Brauer. From Trinidad, C. fune- ' 

 bris, Aust. From Argentina and Brazil, Rogenhofera grandis, Guer. 

 From Brazil, Cuterebra apicalis, Guer. {analis, Macq.), C. cayennensis, 

 Macq., C. rufiventris, Macq., C. nigrocincta, Aust., C. sarcophagoides, 

 sp. n., C. nigricans, sp. n., C. infulata, sp. n., C. schmalzi, sp. n., 

 Rogenhofera trigonocephala, B., R. dasypoda, B., Pseudogametes her- 

 manni, B., P. semiatra, Wied., Dermatobia cyaniventris, Macq., and 

 Gastropikilus asininus, B. 



The paper concludes with notes on the parasitic habits of the 

 American Oestrinae. Dermatobi» hominis is of wide distribution.
