Hah. — Braidwood, on flowers of Bursaria spinosa; Forest Reefs- 



A robust, dirty looking species (closely resembling the preced, 



ing), more densely pubescent on the undersurface than above; the 



scutellum when viewed from some directions appears almost 



white. 



MORDELLA INCONSPICUA, n.sp. 



Black; base of antennae, femora, and base of four anterior tibia? 

 and posterior spurs, testaceous-red. Head and prothorax with

 pretty purplish and steel-blue reflections, which, to a great extent, 

 they lose shortly after death.
