Hah. -Cue, West Australia (H. W. Brown). 



A pair, the sexes, form another of Mr. Brown's interesting 

 captures in this district. The species is very near N. discoflava 

 Fairm., but the head and pronotum are bright metallic, without 

 the coppery margin, the elytra with much narrower dark edging, 

 the yellow extending almost to apex, the head is more tumid and 

 less enclosed in the prothorax than in Fairmaire's species, with 

 the underside different. Type in the author's Collection. 



Stigmodera immaculata, n,sp. 



Oblong-ovate; head, antennae, prothorax, scutellum, underside, 

 and legs, of (J, bright metallic green; of 9, rich golden-coppery, 

 elytra (in both sexes) pale yellow; underside sparsely clothed 

 with short white hair. 



Head finely punctate, with a shallow excavation between eyes. 

 Prothorax narrow, apex truncate, base bisinuate, sides straightly 

 converging from base to apex, anterior angles unseen from above, 

 deflexed and embracing the head, posterior angles subacute; disc 

 finely and closely punctate in front, more coarsely so at base, 

 medial line impressed only near base, two small basal fovese. 

 Elytra of same width as prothorax at base, and about twice and 

 one-half as long, with moderate posthumeral and postmedial 

 enlargements, rounded at apex, with a small circular excision 

 bounded externally by two short sharp black spines, sides near 

 apex entire; striate-punctate, intervals convex and finely punc- 

 tate, apex of abdomen truncate in ^J, rounded in 9; underside 

 finely punctate, prosternum, especially the sides, more coarsely 

 punctate. Dimensions : 8 x 3*5 mm.

Of the *S'. sexguttata Macl., {S. puella Saund.), and S. dispar 

 Blackb., type, but larger and wider than Macleay's species, and 

 the elytra without any markings. Two specimens, the sexes, 

 received from Mr. Brown, who states that the sexual coloration 

 is constant. The shape of the prothorax is unusual, narrow and
