A suboblong, metallic species, apparently allied to 

 hirticolhs, but differing from description in the elytra and 

 scutellum ; it is about the length of pubicollis, but is narrower, 

 pubescence denser, elytra conspicuously shagreened, etc. ; 

 whitei is larger, with sparser pubescence, legs differently 

 coloured and elytra differently sculptured. The pygidium 

 on some specimens appears to have a median line, but this is 

 due to the pubescence. 



Ditropidus davisi, Saund. 

 A specimen of this species with the head entirely pale 

 was taken at Ooldea.

PSYLLIODES ARIDA, n. sp. 



Dark brassy-green; under-surface piceous-brown, elytra 

 and legs flavous with a more or less brassy-green gloss, 

 antennae flavous, from one to five apical joints infuscated. 



Head with coarse and rather dense punctures, becoming 

 much smaller and sparser on clypeus. Antennae ten-jointed, 

 first joint about as long as second and third combined, second 

 slightly longer than third. Prothorax almost twice as wide 

 as the median length, sides narrowly margined and with a 

 slight apical projection ; punctures rather crowded and sharply 

 defined, but smaller than on head; with a feeble median line. 

 Elytra with well-defined rows of moderately large punctures 

 in feeble striae; the interstices with minute punctures. Hind 

 femora very stout, about twice as long as greatest width ; hind 

 tibiae tridentate on each upper edge, and with an apical spur ; 

 basal joint of hind tarsi as long as the rest combined. Length, 

 2§-3 mm.
