This and the two following species I cannot structurally 

 distinguish from limbafipennis (of which two more or less 

 constant forms are already known), but the strikingly different 

 plan of colouration warrants them being described as new, 

 even if the names eventually have to be regarded as varietal. 

 The present one is distinguished from piceitarsis (apart from 

 colour) by its larger size, slightly more convex form, larger 

 eyes, and more shining prothorax. From the description of 

 pallida by its larger size and entirely pale antennae and under- 

 surface. From the pale form of dimidiata its elytral punctures 

 distinct to apex will readily distinguish it. One specimen from 

 Cairns has the knees, tibiae, and tarsi rather deeply infuscated, 

 and the elytral punctures rather lightly so. Another from 

 Roebuck Bay (^3) has the elytra and appendages (knees ex- 

 cepted) conspicuously flavous. 



Rhyparida mediorufa, n. sp. 

 PI. vi., fig. 47. 



Reddish-castaneous ; elytra (a wide sutural space, some- 

 times disapjDearing posteriorly, and the margins excepted) and 

 most of legs black or blackish ; parts of under-surface and of 

 antennae infuscated (sometimes rather feebly so), palpi flavous. 

 Length, 6-7 J mm. 



Hah. — Queensland: Coen River (W. D. Dodd). Type, 

 I. 3063. 



The six specimens before me have almost identical mark- 

 ings, except that on some of them the pale sutural portion of 

 the elytra is continued to the apex, whilst on others it 

 terminates before same. 



Rhyparida atra, n. sp. 

 PL Yii., fig. 96. 



Black; parts of head, and occasionally other parts, 

 obscurely reddish or testaceous ; palpi and a variable portion 

 of antennae flavous. Length, 6-7 mm. 



Hah. — Queensland (British Museum, from F. P. Dodd), 

 Charters Towers (Blackburn's collection), Cairns district (E. 

 Allen and A. M. Lea). Type, I. 3088. 



In colour like the black variety of dimidiata, but elytral 

 punctures and striae quite conspicuous to apex. Some speci- 

 mens (except for the labrum, antennae, and palpi) are entirely 

 black, but on the majority of them the clypeus and a space 

 behind same (usually triangularly encroached upon in the 

 middle) and the claw joints are usually paler, occasionally also 



(53) This and the Cairns specimen are the only ones I have 

 seen from outside of the Northern Territoiy^ where the species 

 appears to be abundant.
