Tlie large black patch of the upper surface has an almost 

 triangular outline; on one specimen, however, this triangle, 

 though traceable, consists of slightly variegated and not much 

 darker scales than elsewhere, whilst the scales on its head and 

 rostrum are of a dingy grayish-white. Of the (six) specimens 

 under examinatiou, two were taken with the sweep net, two were 

 beaten from a common Acacia, one was taken from the stomach 

 of a magpie, and the other was received from the Australian 

 Museum without label, but was probably taken by Mr. Masters 

 at King George's Sound. 



Genus Nechyrus, Pascoe. 



Journ. Linn. Soc. 1871, p. 203. 



As this genus is numerously represented in the Malay Archi- 

 pelago and but sparingly in Australia, I have not considered it 

 advisable to give a formal generic diagnosis, which of necessity 

 could be based on but few Australian species. The main features 

 of the genus, however, appear to be the small head, small and 

 finely faceted eyes, long and thin rostrum, short scape, small but 

 distinct scutellum, open mesosternal receptacle, and soldering 

 together of two basal segments of abdomen. 



The Australian species may be thus tabulated: — 



Femora edentate legitimus, n.sp. 



Femora dentate. 



Scape aim ost the length of f unicle latipennis, n. sp. 



Scape much shorter than f unicle. 



Prothorax slightly transverse incomptus, 'P&sc. 



I'rothorax slightly wider than long mollipes, n.sp. 



Nkchyrus incomptus Pasc; Mast. Cat. Sp. No.5566. 



Depressed, elliptic-ovate. Black, opaque; antennae dull dark 

 red; rostrum shining. Densely clothed with ferruginous-brown 

 scales which are rounded in shape and not closely applied to 

 derm, they are largest on the prothorax, at the apex of which they 

 are paler and bifasciculate; elytral tubercles fasciculate. Under 

 surface with sparser scales than upper; tibiae with stout brownish 

 and sooty setae or elongate scales, claw-joint with a few distinct 

 sets©.
