femora wiili the basal half or two thirds orange. Wiugs as 

 in the male. 



This species varies somewhat in tlie colouring of the 

 abdomen and legs, some specimens being considerably darker 

 than others ; there is also some variation in the colouring of 

 the wings, which have usually a pale brownish tinge, but are 

 occasionally blackish ; also the third veinlet from the discal 

 cell varies considerably in length. In Mr. P. M. Littler's- 

 collection, there are two females from Mt. Arthur, which differ* 

 considerably from the type ; they are unusually small and 

 have the thoi-ax emerald instead of bronze green ; they have 

 somewhat the appearance of belonging to a distinct species, 

 but I consider them to be merely a variety (possibly a moun- 

 tain one) of A. incisuralis. 



This species, though not always to be met with, is distinctly 

 common at times. I have found it in Spring (October 12 to 

 beginning of November) and Autumn (March 29 to May 1). 

 Mr. Littler has also met with it at Launceston, from Feb- 

 ruary 20 to March 21 . 



It may usually be found settled on low vegetation, and 

 also occurs not uncommonly on windows. The female seems 

 to be much more common than the male. 



ACTINA COSTATA, Sp. nov. 



A small species having the thorax, scutellum, and scutellar 

 spines dark metallic green, abdomen blackish brown, and legs 

 yellow. 



Length. Female, 4.5 mm. 



Hab. Bagdad. 



Female. Face covered with white pubescence ; front 

 blackish geneous ; antennae with first and second joints brown, 

 third black. Eyes somewhat broadly separated, bearing 

 short pubescence. Thorax and scutellum brilliant metallic 

 green, with short pubescence; scutellum with six short 

 metallic green spines. Abdomen dark blackish brown. Legs 

 yellow, with the knees of posterior pair and apical tarsal 

 joints darkened. Wings tinged with brown, except for a 

 perfectly hyaline spot between the pale brown stigma and the 

 cubital fork ; space within the cubital fork distinctly brown ; 

 discal cell emitting four posterior veins, the third extending 

 barely half-way to the wing margin ; cubital vein distinctly 

 curved, with the fork large ; costal margin of wing sinuated. 



The distinctions between this and the previous species 

 have already been referred to. 



This species is scarce. I have only come across a single 

 specimen, which I swept from grass growing in a small tarn 

 in the hills at Bagdad, on January 25, 19LS.
