fistulas, anil sinuses, and tlio animal dit's from soptlei-niia or exhaustion. As 

 the uiagcgots mature they droi) to the jtround and i)ui)ate in the soil. The life 

 cycle does not extend over 3 weeks and the larvte or maggots develop in less 

 than 10 days. Curative and preventive measures are briefly considered. Tht^ 

 advantages and disadvantages that would result from the introduction of the 

 turkey buzzard are discussed and correspondence on this subject with the Bio- 

 logical Survey of this Department is presented. 



The life history and habits of the maggot fly or blow fly of Australia (C. 

 occanicw) as worked out by Froggatt are briefly considered. Several speci- 

 mens of the English blue-bottle fly {Ludlia sericata) have been taken with 

 C. dux on the Island of Molokai, and an account of its life history, habits, etc., 

 as worked out by C. Warburton and by G. T. Brown is discussed at some length. 

 The screw-worm fly {CoDipsoinyia itiaccllaria) is said to have been observed on 

 the Island of Molokai. The American blue-bottle fly (L. cwsar) lias been re- 

 cordeil from the Island of Hawaii l)y Grimshaw. SarcoiJhagn barbata has been 

 bred in immense numbers upon meat, and with .S'. iKiUincrriK has been collected 

 from the islands of Oahu and Molokai. The injurious sheep botfly or head mag- 

 got (CEstrus oris) has been recorded from the Island of Kauai by Grimshaw. 



Under insects affecting horses the author considers the stable fly, the horse 

 botfly, which is common in the Territory, and the horse chin fly (GastrophUuH 

 nasalis), which has been collected from both Oahu and Kauai. Brief mention 

 is also made of several parasites of hogs, dogs, and poultr3^ 



The mosquitoes of the Philippine Islands, Clar.\ S. Ludlow ( Washington, 

 J908, PI). 65). — Records are here presented of the distribution of certain species 

 and their occurrence in relation to the incidence of certain diseases. 



Remarks on the study of biting flies, with special reference to the genus 

 Glossina, A. E. H.\merton and H. R. Bateman (Jour. Roy. Army Med. Cor/j.s', 

 11 (1908), JVo. 1 pp. 24-45, figs. 3). — This article is an introduction to the prac- 

 tical study of the life history and general anatomy of flies concerned in the dis- 

 semination of trypanosome diseases. A list of 32 references is appended. 



The Ixodoidea or ticks, G. H. F. Xuttall {.Jour. Roy. Inst. Pub. Health. 

 16 (1908), Xo. 7, pp. 385-403, figs. 20).— In this, the first Harben lecture, the 

 author discusses the ticks, their life history, habits, and role in disease trans- 

 mission. 



Spirochetosis in man and animals, G. H. F, Nuttall (Jour. Roy. Inst. Pub. 

 Health, 16 (1908), No. 8, pp. 449-464). — In this, the second Harben lecture, the 

 author considers the spirochetes, their disease production, and conveyance by 

 ticks and bugs. 



, Piroplasmosis, G. H. F. Nuttall (Jour. Roy. Inst. Pub. Health, 16 (1908). 

 No. 9, pp. 513-526, figs. 3). — This is the third of the Harben lectures delivered by 

 the author. A general account is given of the diseases produced by Piroplasma, 

 their correlation with the Ixodida^, life cycle, etc. 



The role of ticks in the transmission of disease, Meuleman (Ann. Med. 

 Vet., 51 (1908), Nos. 8-9, pp. 460-469; 10, pp. 540-552).— FoWowing a brief 

 review of the role of insects and arachnids in the transmission of disease the 

 author discusses at length the part played by ticks. A table which illustrates 

 the biology of the ticks implicated and the manner of transmission is appended. 



Apiculture, T. W. Kirk (New Zeal. Dcpt. Agr. Ann. Rpt., 16 (1908), pp. 

 158-162, pis. 4). — The bee industry is said to be rapidly expanding in New 

 Zealand. The report of the work of the year by I. Hopkins, apiarist, is here 

 included. From specimens of diseased combs forwarded to the Bureau of Ento- 

 mology of this Department it was determined that the American foul brood 

 occurs in the Dominion.
