the Museum they terminate just before the apex. In my table it would Ix' placed 

 in T, mm, with R. didyma, which is a much larger and otherwise very different 

 species. R. mrdiovittata ha.s the elytral markings shorter and not touching the 

 sides, and the prothorax bimaculate. 



RHYPARIDA NIGRIVENTRIS sp. nov. 



Castaneo-flavous, an apical U on elytra, and abdomen l)lack; knees, tips of 

 tibiae, tarsi and apical two-thirds of antennae infuscated. 



Head subopaque with scarcely visible punctures, except on clypeus, where 

 there are a few distinct ones; front of clypeus conspicuously notched. Eyes 

 rather large and widely separated. Prothorax subopaque, twice as wide as long, 

 sides evenly i-ounded, all angles armed ; punctures sparse and small. Elytra 

 distinctly wider than prothorax ; with rows of not very large punctures, becoming 

 inconspicuous posteriorly. Femora stout and unarmed ; claws bifid. Length, 

 4-4-25 mm. 



Ilah. Northern Terirtory : Darwin. Type, I. 11984. 



The sides of the U are al)out half the length of the elytra, on one specimen 

 its sides are entire, on another each side is encroached upon l)y the flavous por- 

 tion. From some directions parts of the flanks of the prosternuni appear to be 

 very feebly striated. In my table the species would be referred to T, and from 

 the two species placed there, R. trimaculata and didyma, it differs in being much 

 smaller, and very differently coloured. 



RHYPARIDA OBLIQUA sp. nov. 



Pale castaneo-flavous. 



Head without punctures, except for a few minute ones at Ijase and on 

 clypeus ; median line faint. Eyes rather large and widely separated. Prothorax 

 at base about twice as wide as the median length, sides obliquely diminishing in 

 width to apex, angles unarmed ; impunctate or almost so. Elytra rather short ; 

 with rows of punctures of moderate size, becoming much smaller posteriorly. 

 Femora stout, edentate; claws bifid. Length, 4-5-5 mm. 



11 ab. Northern Territory: Darwin, in January (G. F. Hill). Type, 

 1. 11985. 



The prosternum is without striae, even near the coxae ; the elytral punctures 

 are not very large, their true sizes may be noted from oblique directions, but 

 owing to "water-logging" on several of the, six, specimens before me they appear 

 to be very large, even near the apex. Even the tips of the antennae are not 

 infuscated. Readily distinguished from the other pale species of the genus by the 

 oblique sides of prothorax, each of these being quite straight from base to apex,
