Arabia)! specimens of Anopheles rhodesiensis, Theo. {A. d'thali, Patton), 

 were obtained from small pools in the bed of the Tiban River. In 

 Muscat, the larvae were found in holes in volcanic rock fed by under- 

 ground water, in contradistinction to those of A. funestus, which 

 always occur in water having perceptible movement. Some adults 

 were caught in houses. This species is distributed in Africa, Arabia, 

 Baluchistan and Quetta. A. turkhudi, Liston, has not been recorded 

 east of longitude 80° and. is commonest in the north-west of India, 

 facts which suggest that its main area of distribution is further west. 

 A. cinereus, Theo., A. costalis, Theo., and A. pretoriensis, Theo., are 

 recorded. The Mesopotamian species described are A. stephensi, 

 Liston, A. 'pidcherrimus, Theo., and A. sinensis var. mesojwtamiae, 

 var. n.

Specimens of A. brevipalpis, Roper, were captured at Morib, Selangor, 

 F.M.S., in December 1914. Malaria was prevalent in the district at 

 this period and this species was probably the cause of the outbreak. 

 Young larvae were reared from eggs deposited by the captured females. 

 None reached maturity, owing to attack by a species of Vorlicella. 

 A new genus, Moimemyia, is proposed for this species.

Forty species of mosquitos are known to occur in New Jersey ; 

 of these, 20 are troublesome and 6 are classed as pests. They may be 

 classified into salt-marsh, swamp, woodland and house groups. 



The salt-marsh group includes Anopheles quadrimaculatus, Say, 

 A. crucians, Wied., Ochlerotatus (Aedes) sollicitans, Wlk., 0. 

 {A.) taeniorhynchus, Wied., 0. {A.) cantator, Coq., and Culex salinarius, 

 Coq. The first is essentially a frequenter of houses ; the second breeds 

 both in salt marsh and swampy areas inland ; the remainder breed 

 exclusively in the salt marshes. The most important natural enemies 

 of this group are certain fish, namely, Fundidus majalis (striped 

 killifish), F. heteroclitus macrolepidatus (common killifish), F. diaphanus, 

 L'ucania parva (rainwater fish) and Cyprinodon variegatus (variegated 

 minnow). The control of the salt-marsh mosquitos is a matter of so 

 draining the marsh that the water is drawn off at frequent intervals 

 or is kept constantly supplied with some of the above fish. When an 

 opening to the ocean is impossible, the breeding area is trenched with 

 ditches 10 inches wide and 30 inches deep, which communicate with 

 each other or with a central pool, which is constantly stocked with 

 fish. The use of dykes and sluice-gates is a phase of salt-marsh drainage 

 which merits careful consideration as a means of eliminating mosquitos. 

 When the position of a marsh is such that the improvement is financially 

 worth while, mosquito breeding can be eliminated by filling in the 

 breeding area with soil or garbage.
