in the short spines, the third costa originating behind the 

 humeral callus and not quite extending to apex, the sides and 

 suture also subcostate; between the suture and first costa is 

 another shorter raised interval on basal half; all costae smooth 

 and nitid, the interspaces densely and rather finely punctate. 

 Prostemum ai*d metasternum with large, rather distant punc- 

 tures; abdomen densely and finely punctate. Dim., 11*5 x 

 3 '5 mm. 



Hub. — Australia. Type in National Museum, Melbourne. 



A single specimen from the French Collection in the 

 Melbourne Museum bears no locality label, but is so distinct 

 from all known species as to deserve description. While 

 carinated, somewhat as in impressicollis, Macl., and spinolae, 

 C. and G., so far as the elytra are concerned, it is very 

 different in colour and form, notably in the curiously 

 patterned pronotum and the quite irregular base of the elytra, 

 with the angle not fitting into but overlapping the prothorax. 

 It is unfortunate that the locality has not been accurately 

 noted for this pretty little species. 



Stigmodera sexnotata, n. sp. 

 PI. x., fig. 28. 



Elongate-ovate, attenuate in front and behind. Mouth 

 and scutellum blue, head greenish-bronze, prothorax red, this 

 colour extending over the prothoracic episterna, with a spade- 

 shaped discal spot green-bronze, widely covering the apical, 

 narrowly the' basal half; elytra rufo-sanguineous, the discal 

 parts paler, with the base and six spots blue, three a little 

 in front of the middle, the sutural one slightly in front of the 

 other two, three behind the middle, the sutural one behind 

 the other two; sternum green-bronze; abdomen blue, densely 

 clothed with white adpressed hair. 



Head excavated, channelled, closely punctate. Prothorax 

 convex, widest behind middle, apex arcuate, base strongly 

 bisinuate, middle lobe produced, sides widely rounded a little 

 in front of base, thence arcuately converging to apex, anterior 

 angles embracing the head, and (seen from above) acute, 

 posterior slightly produced, acute; disc densely punctate, a 

 smooth depressed medial line on basal half terminating in a 

 small fovea. Scutellum subcordate, depressed, laevigate. 

 Elytra of same width as prothorax at base, widened behind 

 shoulders, thence nearly straight, not much narrowed and 

 minutely denticulate towards apex ; each apex sharply 

 bispinose, with a short internal and a rather pronounced 

 external spine; striate-punctate, intervals nearly flat and 

 rather densely punctate. Sternum strongly, abdomen finely
