described as new, namely, Culex (Culicelsa) ahdominalis, C. {Culicelsa) 

 consimilis, C. {Culicelsa paludis) and Ochlerotatus {Pseudohowardina) 

 linealis. Stegomyiafasciata, F., is stated to occur throughout the whole 

 year, all along the Queensland coast, and Ctdex fatigans is equally 

 ubiquitous, being the common house mosquito. Only two Anoj^heles 

 are mentioned : A. (Myzorhynchus) bancrofti and A. {Nyssorhynchus) 

 annidijjes, Walk. The former is noted as being a vicious biter and preva- 

 lent throughout Northern Australia, while the latter is relatively scarce. 



Of the Tabanidae, or " March Fhes " as they are called in Australia, 

 nine species of Tabanus only are listed, all being fully described. Six 

 species are considered to be new, viz., fuscijjes, lineatus, pseudoardens, 

 nigritarsis, tetralineatus and parvus* Anew species of Culicoides is also 

 described, from Townsville. 



Ten species of ticks are recorded, of which Argas persicus, Fisch., 

 Haemaphysalis australis, Neum., Hyalomma aegyptiurn, L., Boophilus 

 australis, Full., and Ixodes Jiolocyclus, Neum., the common scrub tick, 

 are of economic importance. 



LouGHNAN (W. F. M.). Phlebotomus Fever and Papataci Flies in 

 Aden. — Jl. R. Army Med. Corps, London, xxi, no. 4, Oct. 1913, 

 pp. 402-405. 



Though Phlebotomus fever was first described as occurring in Aden 

 in 1910, an examination of the annual reports from 1907-1909 shows 

 a large number of admissions under " Pyrexia of uncertain origin." 

 The hospital records of the 18th Indian Infantry, stationed at the 

 Crater, Aden, for 1912 were examined, and from these it appeared 

 that 108 cases of pyrexia of uncertain origin were admitted. The 

 blood from all these cases was examined for malarial parasites, but none 

 were found. The clinical symptoms were typical of Phlebotomus 

 fever. The monthly incidence of the fever in the years 1907-1909 

 shows that it was epidemic in June and July, as was also the case for 

 the fever in 1912, and this suggests that all these cases were really 

 sand-fly fever. At Aden the symptoms vary considerably in severity. 

 The mortality is nil, and the disease appears specially to affect new- 

 comers. The distribution of the fever varies from year to year ; in 

 some years it is most prevalent at the Crater, in others at Steamer 

 Point which is somewhat higher. Malaria is not endemic at 

 Steamer Point nor at the Crater. The troops are practically free 

 from enteric fever, and it is uncommon amongst the civil population. 

 The eight-day continued fever of Crombie is frequently met with ; 

 dengue appears sporadically, but no serious epidemic has been noted 

 since 1872-3. The fever seems to be most prevalent from the 

 beginning of May to the end of October ; there is a definite relation- 

 ship between the climatic conditions and the fever ; the season of 

 high temperatures and greatest humidity produces the highest 

 admission rates. 



Four specimens of sand-flies captured in the beginning of June 

 were found to be Phlebotomus minutus. The adults have been found 

 in dark places in houses and in the caves frequented by camel men and 



[* Two of these names, fuscipes and lineatus, have already been used in 

 the genus, and therefore cannot stand. Mr. E. E. Austen is pubUsliing a note, 

 in which he is revising some other points in the nomenclature in this paper.
