the head/56) that I am averse to regarding it as distinct; its 

 head, however, is shagreened, has small but distinct punctures, 

 becoming larger and fairly dense on clypeus, medio-frontal 

 impression feeble and disconnected, and posterior suture of 

 clypeus absent. The type is a male, the Mackay specimen a 

 female, but the differences mentioned are probably not sexual. 



Rhyparida semiflava, n. sp. 



Flavous ; elytra (extreme base obscurely diluted with red),, 

 scutelluni, mesosternum, metasternum, and abdomen black;, 

 apical half of antennae infuscated. 



II fad with fairly dense and well-defined punctures about- 

 base, becoming sparser towards front, and then somewhat 

 coarser and denser on clypeus ; medio-frontal impression rather 

 shallow. Eyes not very large, very prominent, and widely 

 separated. Prothorax about twice as wide as long, front 

 angles lightly armed ; with moderately dense and rather small 

 punctures, becoming slightly denser and larger on sides. Elytra 

 across shoulders somewhat wider than prothorax, sides dilated 

 to beyond the middle ; with rows of fairly large punctures, 

 becoming much smaller towards but traceable to apex. Flanks 

 of prosternum striated only about extreme base. Femora very 

 minutely dentate ; claws bifid. Length, 3 mm. 



Hah. — Queensland: Mount Tambourine (A. M. Lea). 

 Type (unique), I. 3069. 



A small species, in general appearance close to the two 

 preceding ones, and in shape almost intermediate, but dis- 

 tinguished from both by the much more distinct cephalic punc- 

 tures, and the rows of elytral punctures more distinct to the 

 apex. From basipcnnis it is further distinguished by the more 

 shining prothorax, with more rounded sides, and very distinct 

 punctures, and by its black metasternum. From seminigra by 

 the prothorax with more conspicuous punctures, the front 

 angles armed, and b}- the black scutellum. 



Rhypaeida humeralis, n. sp. 

 PI. vii., fig. 58. 

 Piceous-brown, sometimes almost black; head, shoulders, 

 and apical third of elytra (except suture) and appendages of 

 a dingy-flavous or testaceous. 



Head with scarcely visible punctures, except on clypeus, 

 where they are small but sharply defined ; medio-frontal im- 

 pressions short and disconnected ; clypeal suture distinct at 



(56) Its elytra, however, are slightly dilated to beyond the 

 middle, and on the type they are parallel-sided ; probably a sexual 

 difference.
