Records of Dees. 500 



s.m. comparatively broad. Legs dark, with light hair, 

 partly dark on tibia? ; hair on inner side of basitarsi pale 

 orange to yellowish white. Abdomen dullish, the minutely 

 punctured surface appearing granular; a small patch oil 

 white hair at each side of first segment, and entire or nearly 

 entire conspicuous white hair-bands on second to fourth ; 

 hair at apex dark reddish fuscous. 



£ . — Similar in most respects ; eyes strongly converging 

 below; broad lower margin of clypeus honey-colour; an- 

 tennae very long, the flagellum 5 mm., reddish and strongly 

 crenulate beneath ; scape red in front ; tongue as in female; 

 hind margins of second and following segments pallid ; ante- 

 rior and middle tibiae at apex and base, and wholly in front, 

 hind tibire except a large patch on outer side, and all the 

 tarsi rather dull ferruginous ; hind femora strongly incras- 

 sate ; hind tibiae also thick, with an obtusely angular projec- 

 tion on inner side near apex. 



1 thought at first that this might be a colour-variety of 

 N. frenchi, Ckll., but the fourth ventral segment in middle is 

 smooth and shining, with a strong sulcus, which ends a little 

 before the emarginate apex ; whereas the fourth ventral in 

 frenchi is roughened and slightly ridged in middle, with a 

 rudimentary sulcus at extreme base. 



Hub. Brisbane, Queensland (tvpe-localitv), females, 

 Sept. 18, 1911, and Oct. 3, 1912 \H. Hacker; Queensl. 

 Mus. 42, 79) ; Stradbroke Island, male, Dec. 3, 1912 

 [H. Hacker; Queensl. Mus. 85). A female with darker 

 tegulse and ochraceous-tinged abdominal bauds is labelled 

 "Oakleigh, Victoria " {French; Froggatt, 183). 



Closely related to N. mcerens, Smith, but less robust and 

 with much lighter teguhe. In N. mcerens the basal area 

 of metathorax is not narrowed in the middle. N. generosa, 

 which is supposed to be the male of mcerens, has not enlarged 

 hind femora and tibiae. 



Euryylussa uurescens, sp. n. 



$ . — Length a little over 7 mm. 



Similar to E. ephippiata. Smith, but smaller, with the red 

 thoracic colour much lighter, inclining to orange ; post- 

 scutellum black; wings hyaline; mesothorax less strongly 

 punctured. 



Hub. Mackay, Queensland, Nov. 1891 {Turner, 701). 



I had determined this as E. ephippiata, but the real 

 species of that name is now before me (llealsville, Victoria ; 

 iSat. Mus. Victoria, 181), and is clearly distinct.
