stout, middle ones each with a strong, triangular, median tooth 

 on outer edge. Length, 4^-51^^ mm. 



Hah. — Queensland: Coen River (H. Hacker). 



There is a feeble irregular sooty blotch on the elytra, ex- 

 tending from the suture to the fourth interstice ; on the pos- 

 terior declivity there are also some small irregular spots. 



PSEPHOLAX LATERIPENNIS, n. Sp. 



Dark chocolate-brown. 



Head with coarse partially-concealed punctures. Rostrum 

 about once and one-half as long as greatest width ; with dense 

 and rather coarse punctures, partially concealed towards base, 

 towards apex smaller but clearly defined. Scape not much 

 shorter than funicle, club rather large and briefly ovate. Fro- 

 thorax moderately transverse, sides moderately rounded, but 

 at apex suddenly narrowed and subtubular : with very dense 

 punctures. Elytra not much wider than prothorax, but some- 

 what dilated near base, which is strongly trisinuate ; with rows 

 of not very large punctures, in narrow striae ; interstices with 

 dense punctures and numerous small granules. Under-surface 

 with moderately dense punctures. Mesosternal receptacle 

 acutely produced on each side in front. Femora stout, feebly 

 dentate ; middle tibiae each with a strong triangular median 

 tooth on outer edge, and a fairly large subapical outer one. 

 Length, 6-6|^ mm. 



Hah. — Queensland: Brisbane (R. Illidge) ; Mount 

 Tambourine. 



Nearer humeralis than any other described species, but 

 elytral sculpture very different, rostrum longer, etc. The 

 clothing varies from pale-golden to stramineous or ochreous. 

 On both specimens it is very dense on the sides just behind the 

 shoulders and moderately dense on the posterior declivity, the 

 rest of the elytra being almost glabrous (probably due to 

 abrasion). Each prothoracic puncture contains a short scale. 

 On the flanks of the sterna and tip of first abdominal segment 

 the scales are stouter than elsewhere ; on the rest of the under- 

 surface and legs the clothing is more or less setose. The finer 

 sculpture of the elytra is probably concealed on specimens in 

 perfect condition. 



PSEPHOLAX BASALIS, n. Sp. 



Chocolate-brown. Upper-surface moderately clothed with 

 short more or less golden scales, in places obscurely variegated 

 with obscure sooty patches. Sides of sterna with paler and 

 wider scales ; rest of under-surface and the legs with setose 

 clothing.
