MiCROCALLIPHOBA VABIPES. 



The larval feeding period generally occupied 3 days in 

 January and 4| to 5 days for most of the year ; while the 

 larval resting period usually extended over 1 or 2 days in 

 summer but 5 or 6 in winter. The pupal period commonly 

 occupied 4 to 4| days in summer. 



Chrysomyia megacephala Fabr. 

 This large, deep-blue blowfly is more commonly known in 

 Queensland, the East Indies, and Hawaii as C. dux Esch. Van 

 der Wulp in his " Catalogue of the described Diptera from 

 S. E. Asia" (1896, p. 148) quotes the latter name with Lucilia 

 flaviceps of Macquart and of Walker as a synonym. 



Froggatt has referred to it frequently and figured it as 

 Lucilia tasmaniensis (Brisbane, New Hebrides, and Solomon 

 Islands), but recently (1921, p. 812) has recorded it as C. 

 flaviceps apparently on the authority of W. S. Patton, Avho 

 reports it as a common '' bluebottle" blowfly of Eastern 

 bazaars and as one which breeds readily in decaying animal 

 matter. 



It appears in Brisbane in great numbers during the 

 summer but does not become the dominant species until about 

 March. It occurs in Sydney but is not so abundant there. 

 The British Museum contains specimens from the Northern 

 Territory and many North Queensland locahties.
