The mosquitos collected included : Culex tarsalis, C. fatigans, 

 €. spissipes, C. chrysonotum, C\ siniilis, Psorophora jamaicensis, P. iexa- 

 nuni, P. signipennis, Mansonia spp., Anopheles crucians, A. punctipennis, 

 and A. pseudopunctipennis. The last-named was found breeding 

 throughout the summer months. Culex fatigans was the most prolific 

 of the mosquitos and was found breeding from AprU to December. 



As a result of careful inspection and subsequent treatment, Stegomyia 

 fasciata {Aedes calopus) was entirely absent during 1918, although a 

 few individuals were taken at San Antonio, Texas, about 6 miles to the 

 north-east.

 369. 



Attention is called to the occurrence of a Phorid, Aphiochaeta 

 scalaris, Tw., in milk in Georgia. The larvae of this fly have been 

 recorded as attacldng onions in the West Indies, living on decayed 

 insects in Brazil and parasitising Hyphantria cunea in Florida. 



A. ferruginea, Brunnetti, which, according to Malloch, is a synonym 

 of A. scalaris, has been recorded as causing myiasis of the intestine 

 in man, where it is able to complete its life-cycle. The presence of this 

 fly in milk suggests a possible method of its reaching the human 

 intestine.

 ii, no. 6, June 1920, pp. 317-351. 



The cattle tick, Boopliilus annulatusausiralis, occurs now in practically 

 all parts of Queensland where climatic conditions permit its establish- 

 ment. The life- history is described and the methods of control are 

 briefly dealt with [R.A.E., B, vii, 12, etc.]. The necessity for a 

 widespread educational campaign to convince the population of the 

 advisability of thorough tick eradication is emphasised.

 of Horses. — Science & Industry, Melbourne, ii, no. 6, June 1920, 

 pp. 369-372. 



Experiments have been made to determine whether any of the 

 parasites, Habronema muscae, H. megastoma and H. microstoma, can 

 complete their larval cycle in various Queensland flies, especially those 

 that are commonly associated with horses and cattle. The species 

 dealt with include : Musca domestica, L. ; M. fergusoni, Jnstn. & 

 Bancr. ; M. vetustissima, Wlk. ; M. terraereginae, Jnstn. & Bancr. ; 

 M. hilli, Jnstn. & Bancr. ; Stomoxys calcitrans, L. ; Sarcophaga misera, 

 Wlk. ; Pseudopyrellia sp. ; and the common blow-fly, Anastellorhina 

 augur y F. All these species were found able to harbour the larvae of
