ENTOMOLOGY

180 SANITARY ENTOMOLOGYtheater, especially during 1915. It infested wounds and interfered withtheir proper treatment and also was responsible for many infestationsof the genitalia of cows in that region.Next in importance comes the flesh fly, Sarcophaga camaria L~nnaeu'3.This form does not seem so prone to attack living animals as Wohlfahrtiamagnifica Schiner, but there are numerous cases of myiasis in old suppuratingsores. These may occur in any part of animals or man. In thePetro grad district Lucilz'a caesar Linnaeus is responsible for some cases ofmyiasis, while in Denmark, Holland, and parts of Germany and France,L. sericata Meigen is conce~ned in the iil.festation of wounds. Calliphoraerythrocephala Meigen, Musca domestica Linnaeus and Muscma stabulanaFallen (plate III, fig. 2) are said to oviposit on corpses on the battlefieldsoon after death but before putrefaction sets in.The larvIE of Anthomyia pluvialis Linnaeus has been reported as beingconcerned in auricular myiasis. Probably this species should be consideredas a feeder on excreta rather than placed with tissue-destroyingforms.AFRICA.-Wohlfahrtia magnifica Schiner is reported by Gough inEgypt as being taken from ulcers behind the ears and from orbits ofpatients in the ophthalmic hospitals. In tropical Africa Lucilia argyrocephalaWiedemann commonly attacks mammals, man, and birds. Membersof the genus Pycnosoma, which halL...been included with Chrysomyaby some authors, cause myiasis in numerous caases. Pycnosoma megacephalaand P. bezziana Vin. arc frequently mentioned in literature in connectionwith cases of myiasis in cattle, horses, camels, and other animals,as well as man. P. putorium Wiedemann, P. margin ale Wiedemann, andChrysomya chloropyga (Wiedemann) Townsend are also concerned.Sarcophagids have been recorded as infesting wounds; S. haemorrhoidalisFuller and S. regularis Wiedemann being mentioned in particular.ASIA.-While there are numerous references to myiasis cases in Asia,our knowledge of the species concerned is limited. Members of the genusPycnosoma, particularly P. flaviceps Walker, are concerned with cases inIndia. This species and Lucilia serenissima Fabricius have been mentionedparticularly as being troublesome by attacking cattle after outbreaksof foot-and-mouth disease. It is possible that they may be concernedwith the spread of this disease in addition to the injury wroughtby their burrowing into the tissues. The cosmopqlitan Lucilia COJ8arLinnaeus is responsible for some cases of myiasis. Several Sarcophagidaehave been reported as causing nasal myiasis of man in parts of India, butmost of these have not been specifically determined. S. ruficornisFabricius seems to be among those most frequently concerned.A USTRALIA.-While reports of destructive myiasis in man are comparativelyfew from Australia~ c;eri;l1iJl parts are subjected to veritable
