the sides, and scai'L-ely oblique to the base, which is of equal 

 ■width with the apex. In colour it is very close to the preceding 

 sjiecies. 



Polylohus colohopsis. n.sp. 



Black, shining, legs of a pale dingy brown. With very short, 

 indistinct pubescence. 



Head about as long as wide, behind eyes almost parallel 

 sided. Antennae extending to middle coxae, first joint about 

 as long as three following combined, second longer than wide, 

 third very small, fourth to tenth transverse and feebly increas- 

 ing in width, eleventh ovate, slightly longer than ninth and 

 tenth combined. Prothorax moderately transverse, sides and 

 angles gently rounded, base and apex of even width ; punctures 

 indistinct. Elytra slightly wider than prothorax and about 

 once and one-fourth as long, sides almost parallel : with small, 

 dense punctures. Abdomen parallel-sided almost to apex ; 

 punctures indistinct. Length Ij, to apex of elytra .2-3 mm. 



Hab. — Tasmania : Mount Wellington, in a nest of Colohopsis 

 gasseri (A. M. Lea). 



The minute size and deep black colour readily distinguish 

 this from all other species known to me. Tlie disc of the jDro- 

 thorax on the type is slightly depressed, but this may be due

Polylohus intrej)id'us, n.sp. 



Of a rather dingy brownish flavous, some parts darker. With 

 short, pale and moderately dense pubescence. 



Head feebly transverse, sides gently rounded ; antennae 

 slightly passing middle coxae, first joint moderately long, second 

 slightly longer than wide, third and fourth small, fifth to tenth 

 transverse and of almost even width, eleventh elongate-ovate, 

 the length of three preceding combined. Frothorar moderately 

 transverse, sides and base gently rounded ; punctures indistinct. 

 Elytra, very little wider than prothorax, and along middle no 

 longer ; almost parallel-sided ; with dense and very small 

 punctures. Ahdomen parallel sided almost to apex ; with dense, 

 minute punctures. Length H. ro apex of elytra | mm.
