thiin the prothoi'ax, and the abdomen nowhere piceous. In 

 colour, except that the elytra are darker, they agree with 

 infuscaticDriiis, but have the head somewhat larger and the 

 elytra wider. 



Polylohns daveyi, n.sp. 



Head, elytra and metasternum more or less piceous-brown, 

 prothorax of a dull red, abdomen reddish testaceous ; legs, 

 palpi, and base of antennae somewhat obscurely flavous. 



Head rather small and feebly transverse, hind angles strongly 

 rounded. Eyes small and inconspicuous, antennae just passing 

 base of prothorax, lightly incrassated towards apex, most of the 

 joints distinctly transverse. Prothorax lightly transverse, front 

 angles strongly rounded, sides then slightly oblique, basal angles 

 rectangular ; punctures very indistinct. Elytra more convex 

 than usual, sides feebly rounded ; with very feeble punctures. 

 Abdomen rather narrower than usual, parallel sided through- 

 out ; margins rather strongly and evenly raised. Length 2 

 <(vix), to apex of elytra 1 mm. 



Hah. — Victoria: Forrest, in nests of Ectatomma metallicuin 

 (H. W. Davey) ; N.S. Wales : Sydney, in nests of same species 

 of ant (A. M. Lea). 



Kather more shining than tasmaniensis, obliquity of sides of 

 prothorax more pronounced, and abdomen entirely pale ; elytra 

 uniformly darker than prothorax, although not veiy dark. The 

 outlines of the prothorax are almost exactly as in Com, but the 

 sides do not appear separated from the disc by a shallow longi- 

 tudinal impression ; in consequence the convexity is almost even 

 throughout. 



Two specimens from Tasmania (Launceston) differ in having 

 the elytra diluted with red towards the base. 



Pohjlohits infuscatirorni's, n.sp. 



Of a rather pale reddish testaceous; ; elytra entirely or 

 towards apex, and metasternum slightly infuscated, antennae 

 infuscate except basal jomts ; legs and palpi somewhat flavous. 



Head rather small and feebly transverse, base rather strongly 

 roimded. Eyes small l)ut fairly prominent. Antennae compara-
