Culex annulatus. Stegomyia huscki, Coq., was found in a collection of 

 water in tlie petiole of a fallen palm leaf at an elevation of 2,600 feet and 

 in a cacao pod at the upper limits of cultivation. Larvae and pupae of 

 an unidentified Aedes, probably a new species, were collected from a 

 tree-hole and from a pine in a cacao plantation. The larvae of Mega- 

 rhinus haitiensis, D. and K., were also found in wild pines and tree 

 holes and fed readily on Stegomyia larvae in captivity, Culex {Mic- 

 raedes) conservator, D. and K., w^as found with Corethrella appendiculata. 

 Grab., in similar breeding places and a Culex allied to elevator, 

 D. and K., was bred from a wayside pool. The swamp mosquito of 

 Grenada is OcJilerotatus niger, Giles ; it remains in deep shade during 

 bright sunshine and emerges about an hour before sunset, at which 

 time it will bite as well as at night. Deinocerites cancer, Theo., also 

 breeds in brackish water. 



The sandfly of Grenada, which is a species of Ceratopogon, is prac- 

 tically ubiquitous and causes considerable annoyance, though no 

 disease is known to be carried by it. Its control is difficult, as 16- 

 mesh netting will not keep it out. Of the blood-sucking flies which 

 attack domestic animals, Stomoxys is as common as in England, while 

 Tabanidae are uncommon, though a few unidentified specimens were 

 captured, always in remote places.

 Fly. — Bull. Entom. Research, London, vii, no. 3, January 1917, 

 p. 265. 



Some fly-maggots taken from sheep in Queensland were bred out 

 and found to be referable to two genera, Pycnosoma and Sarcophaga. 

 One has been identified as Pycnosoma ruf fades, Macq., and the other 

 is described as new under the name of Sarcophaga froggatti, sp. n.

A new variety of A. albotaeniatus is described under the name var. 

 montanus. The larvae were found associated with those of A. leuro- 

 sphyrus, Don., and A. aitkeni, Theo., and occasionally with those of 

 A. umbrosus, Theo., in shaded pools in a jungle stream at Selangor, at 

 an elevation of 600 feet.

Exhaustive experiments on the action of kerosene on various species 

 of mosquito larvae were undertaken, the results being described in this 

 article. For some species this measure of control is most successful, 

 but an exaggerated confidence exists as to its efficacy against all 

 mosquito larvae. Experiments show that, in practice, the presence of 

 weeds in ponds is liable to break the film of oil, thus allowing breathing 

 spaces and, in the laboratory, that the presence of organic matter in 

 the water diminishes the action of crude kerosene. To test the action
