POLTLOBUS PALLlDlPENXis AFacl. ( f'oniR'ily lliimalota). 



(P. paUtd-nminor Lea.) 



The original description of P. pallidipennis is too short for identificalam of 

 the species, as it would apply to many small Stnpliyllnidne. There are two speci- 

 mens mounted on one card with a type label, one is in finite unrecognisable con- 

 dition, and the other is somewhat dirty but on comparison with the typo of P 

 paUid-ominor appeared to agree with it, except that the base of its head is not 

 quite as dark as on the type of the latter species, but this may be due to its 

 having somewhat faded. Olliff, on referring the species to Poli/lobtiif. and re- 

 describing it, noted the eh-tra as having "a moderately large indistinct spot near 

 the external apical angles," but I can find no trace of such a spot on eitlier of the 

 Gayndah specimens, so it is possilile that Olliff's description may not liave been 

 drav»-n up from these, as he records the species also from Xew South Wales.

(P. teiiaif' Lea. "I 



A specimen from Shelley's Flats bearing Ollifif's laljcl as P. lotu/iilus (but 

 not marked as the type) agrees with the type of P. leriuis. It agi'ees with the 

 description of tlie structure, but not of the colour, of P. Inngidits. a's the elytra are 

 twice noted as being "pitehy-black" ; whereas on the specimen now before me 

 they are scarcely darker tlian the prothorax, although in some lights appearing in- 

 fuseated posteriorly. Tf the specimen in riuestion is really the type of lo)ii)idiii 

 the original description is misleading. 



POLYLOr.US APICAI.IS Fxl . 



(P. (wufioda Oil.) 



The type of P. fungicnla agi'ees with two Tasmanian specimens that some 

 years ago T identified from its description as P. apicalix, and on checkinsr with 

 that description aoain appear to agree with it. Fauvel notes the pronotum a? 

 having a rather wide basal foveole; on one of the Tasmanian specimens there is 

 a fairly conspicuous transverse impression near the base, but on the other speci- 

 men, and on the iype of fungicrda the depression is scarcely evident. 



PSELAPHIDAE. 



RvDASIs ATKlCEPs Mad. (forincrly Brgaxis) . 



(P. (ic(iiithoslfn)(( Tjca . ) 



There were two males mounted on one card as the types of R. at rice ps. and 

 side by side these agi-ee with the types of P. ncanthosterna. Maeleay did not 

 mention the remarkable features of the sterna, abdomen, and front tibiae, and his 

 description of the elytra is misleading "Elytra bistriatcd. one on each elytron" as 

 there are two conspicuous striae on each elytron: a subsutural one, and a sub- 

 median one. 



Rybasis ei-kctrica King, Vav. A. 



Mr. A. H. Elston took a specimen of this vaiiety from the nest of a species 

 of Pheidole on Kangaroo Island.
