about the middle of each, and the third common to both on 

 the suture near the scutellum. Another specimen has some- 

 what similar but less sharply-defined spots. A specimen in 

 the Macleay Museum is black, except for the head and parts 

 of the appendages. The flanks of the prosternum have many 

 striae extending from base to apex, but on the apical half they 

 are not very sharply defined, they cover a space at least half- 

 way from the coxa to the outer margin on each side, the outer 

 side being smooth ; this character will readily distinguish the 

 species from trimacuJafa, whose prosternum, even at the base, 

 is not longitudinally strigose. 



Rhyparida platyderes, n. sp. 



Reddish-castaneous ; elytra somewhat paler about their 

 apex, abdomen and appendages more or less flavous. 



Head with moderately dense but rather small punctures^ 

 becoming denser and somewhat larger on clypeus ; with a 

 narrow medio-frontal impression, connected with a feeble 

 clypeal suture. Eyes rather large and moderately separated, 

 a shallow groove behind each. Froihorax across middle about 

 thrice the median length, front angles unarmed ; with rather 

 small and not very dense but clearly-defined punctures, almost 

 disappearing before all the margins. T^lytrn suboblong to 

 beyond the middle, very little (at extreme base not at all) 

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

 becoming distinctly smaller towards but distinct to apex. 

 Flanks of 'prosternum striated throughout. Femora minutely^ 

 dentate ; claws appendiculate. Length, 3-31^ mm. 



Hah. — Northern Queensland (Blackburn's collection). 

 Type, I. 3113. 



In general appearance rather close to the preceding 

 species, but head more convex, and with much more conspicuous 

 punctures, eyes rather larger and less prominent, front angles 

 of prothorax more rounded and not armed, and punctures in 

 general slightl}^ difrerent. On the forehead there is a vaguely- 

 infuscate spot. 



Rhyparida prosternalis, n. sp. 



Piceous-brown, sides and apex of elytra slightly paler; 

 abdomen and appendages more or less testaceous. 



Head with small and rather dense punctures, becoming 

 larger on clypeus ; with a narrow medio-frontal impression, 

 connected with a vague clypeal suture. Eyes large, separation 

 about equal to the transverse diameter of an eye. Frothorax 

 about thrice as wide as the median length, sides feebly rounded 

 and decreasing in width from base to apex, front angles un- 

 armed : with fairly numerous sharply-defined but rather small
