184 Arthur M. Lea: 



A rather dingy species. The absence of dense clothing from 

 the sides of prothorax will readily distinguish from any of the 

 preceding species. The median prothoracic punctures are very 

 distinct from certain directions, but indistinct from others. 



Sri/(l//uif litis d u p] iratiis, n.sp. 



Reddish castaneous, appendages paler. Upper surface sparsely 

 clothed with pale, straggling hair or fine setae, becoming denser 

 (but not very dense) on sides of prothorax. 



Head and antennae as described in clientuJus. Protho?-ax 

 distinctly longer than wide, widest almost in middle, which is 

 gently rounded ; base with four deep, isolated punctures, of 

 Avhich the two median ones are slightly larger than the others, 

 each side with a partially concealed oblique impression. Ehjtra 

 oblong ovate, sides rather strongly rounded ; basal depressions 

 rather feeble ; with sparse, indistinct punctures. Length 1 mm. 



Hah. — W. Australia : Swan River, in an ants' nest (A. M. 

 Lea). 



Li general appearance close to daveyi, but more elongate and 

 prothoracic punctures disitinctly isolated, although close together. 

 From some directions the elytra appear to be slightly paler 

 than the prothorax. 



Srydmacuus caManeoglaher, n.sp. 



Of a bright pale castaneous and highly polished, appendages 

 paler. Upper surface glabrous except for a very few hairs or 

 fine setae at sides of prothorax. 



Head very smooth and rather wide ; eyes small and fairly 

 prominent. Antennae distinctly, but not by much, passing base 

 of prothorax, with a distinct four-jointed club, that is as long 

 as the six preceding joints combined. Prothnrar about as long 

 as wide, basal two-thirds parallel-sided, apical third strongly 

 narrowed ; each hind angle with a single deep puncture. Elytra 

 briefly oblong ovate, depressed, sides strongly inflated in 

 middle; basal depression deep but not large; impunctate. 

 Legs long; femora clavate ; hind tibiae longer than usual. 

 Lenorth 4-5th mm.
