three cross-bands, the basal one very broadly inteiTupted 

 m the centre, with the upper part sometimes indistinct, 

 the othei^ entire, but not reaching the hind-margin. 



Female resembles the male very closely, and differs chiefly 

 in the broader and more pointed abdomen. 



,S'. frifosciafus is the commonest species of the genus, and 

 seems to- occur abundantly everywhere in the bush, during 

 the months of December and Januarv. 



SciAPUS GRANDis. Macq. 



This species is described by Macquart as golden-green, 

 with the scutellum blue; antennae black; femora black; 

 iiibise red ; wings hyaline ; the posterior cross-vein sinuated. 



Length. Male, 8 mm. 



Hab. 'Tasmania. ' 



,S'. f/randis is unknown to me ; it should be readily re- 

 <'ognised by the black femora in conjunction with the 

 iiyaline wings and large size. 



SciAPUS EREVicoRxis, Macq. 



Thorax brown, with metallic green and violet reflections ; 

 scutellum violet; abdomen metallic green, with violet re- 

 flections ; legs entirely light yellow ; wings Avith the upper 

 iDranch of the discal vein and the posterior cross-vein suf- 

 -fused with brown. 



Length. Male, 8 mm. 



Hab. Mangalore. 



Male. Face and front grey or black. Antennae orange. 

 Thorax light brown, with green and violet reflections; 

 scutellum violet. Abdomen metallic green, with violet re- 

 flections, the anterior margins of third and fourth segments 

 light yellow-brown ; all segments with long black lateral 

 iDristles ; and second and third segments with also black 

 posterior dorsal bristles. Legs light yellow, the tarsi api- 

 cally darkened; tibiae with a few black bristles. Wings 

 with the upper branch of the discal vein and the posterior 

 cross-vein suffused with dark brown ; posterior cross-vein 

 angulated in the middle, the angulation being marked out- 

 wardly by a conspicuous veinlet ; halteres yellow. 



This species occurs amongst tussocks of long grass; it 

 jippears to be local, but is j^robably common where it oc- 

 •c'urs. My dates range from December 2 to December 24.
