 (Blackburn's collection, from W. Meyrick). Type, I. 3125. 



The shape of the prothorax and its punctures to a certain 

 extent are somewhat as on commutahilis, but the head (includ- 

 ing the eyes) and the elytra and legs are very different. The 

 apical parts of the antennae vary from but feebly infuscated 

 to deep black, the legs are occasionally almost black, the 

 metasternum and abdomen (or the former only) are sometimes 

 darker than the rest of the under-surf ace ; one specimen has 

 a very dark (but not black) head. The elytral punctures are 

 unusually small, and with the striae scarcely defined, even at 

 the base. The punctures on the heads of the smaller speci- 

 mens are sometimes rather more defined than on the larger 

 ones, and on a few specimens there are fairly distinct ones 

 between the clypeus and base. 



Rhyparida pallidula, n. sp. 



Flavous ; apical half (or more) of antennae infuscated. 



Head with fairly dense .and distinct punctures, denser 

 and larger on clypeus, and sparser and smaller between eyes 

 than elsewhere ; medio-frontal impression rather feeble, and 

 feebly connected with base by a scarcely elevated line. Eyes 

 rather small, very prominent, and widely separated. Prothorax 

 about twice as wide as the median length, front angles very 

 feebly, or not at all, armed ; with rather dense and somewhat 

 small punctures, becoming more crowded and larger on sides. 

 Elytra rather short, not much wider than prothorax ; with 

 rows of fairly large punctures, becoming much smaller but not 

 disappearing posteriorly. Flanks of iwosternum transversely 

 striated about base. Femora very minutely dentate; claws 

 bifid. Length, 3 mm. 



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

 Type, L 3431. 



In general appearance close to the pallid form of tropica, 

 but longer and less compact, elytra with less conspicuous punc- 

 tures and striae posteriorly, without the conspicuously thick- 

 ened post-humeral interstice, etc. In size and shape it is fairly 

 close to aemi-fiava, but apart from the very different colours 

 the prothorax is slightly different at apex, the elytra are not 

 dilated posteriorly, and the punctures are not quite the same. 

 Of the two specimens in the Museum one has the under-surface 

 of uniform colour, but on the other parts of the metasternum 

 and of the abdomen are infuscated.
