RHYPARIDA BIVITTIPENNIS sp. nov. 



Reddish-castaneoiis, legs (knees iiifuscated), antenuae and pal])i paler, elytra 

 with a blackish vitta on each side from base to near apex. 



Head convex and with minute punctures, except in front and on the clypeus, 

 where they are fairly large and sharply defined ; median line short. Eyes large 

 and widely separated. Prothorax not twice as wide as the median length, front 

 angles armed ; punctures small and rather sparse in middle, becoming larger and 

 denser, but somewhat irregular on sides. Elytra wdth rows of rather large 

 l)unctures, becoming smaller posteriorly. Flanks of prosternum striated from 

 base to apex, the striae becoming very faint near the margins. Femora stout, all 

 distinctly dentate; claAvs bifid. Ijength, 4-5-5 mm. 



Hal). Northern Territory : Darwin (G. F. Hill, No. 237 ; and W. K. Hunt). 



Some of the specimens are of a brighter red than others ; one is almost flavous, 

 with the vittae reduced to rather small infuscated spots, another has the vittae 

 shorter than usual, with the apex of elytra flavous; each vitta usually occupies 

 about one-third of the base, but about two-thirds posteriorly, on one specimen it 

 extends to the apex itself; parts of the under-surface are sometimes infuscated. 

 The ]")rothorax has some coarse, irregular punctures, but not in oblique rows as 

 in B. polyniorpha; passing that species in my table, it would be associated Avith 

 R. ynaculicoUis and J^. melvillensis, from the former it is distinguished by its 

 wider form, sparser and stronger prothoracic punctures and differently coloured 

 elytra, and from the latter by its smaller size, very different colour and finer 

 elytral punctures. 



RHYPARIDA SEMIOPACA sp. nov. 



Flavous, each elytron with a black lateral vitta. 



Head opaque and with scarcely visi])le punctures, even on the clypeus; 

 median line short. Eyes rather large and Avidely separated. Prothorax about 

 twice as wide as long, greatest wddth at basal third, all angles armed; surface 

 opaque and impunctate. Elytra with rows of not very large punctures, becoming- 

 very small posteriorly ; interstices with scarcely visible punctures. Flanks of 

 prosternum with abbreviated striae near coxae. Femora stout and rather feebly 

 dentate ; claws bifid. Length, 4 mm. 



Hab. Northern Territory: Darwin (G. F. Hill, No. 209). Type, I. 11983. 



Parts of tlie prosternum are very finely striated, but the striae are not 

 continuous from base to apex ; this character, and the opaque, impunctate pro- 

 thorax, readily distinguish the species frcnn the preceding one, to which, at first 

 glance, it a])pears to belong. The elytral vittae are rather narrow at the base, 

 but dilate posteriorly till they cover most of the surface; on the two specimens in
