0. Jloccosus, Schenkl. I have in my collection a Glerid which 

 agrees with Herr Schenkling's description of this species in every 

 respect except that it has the palpi of a Natalis and should be 

 referred to that genus. As Schenkling states that Jloccosus has 

 the palpi of an Opilo I am compelled to suppose that the insect 

 before me is not his species in spite of its agreement in other 

 respects with his excellent description. 1 shall not however 

 venture on describing it on the ground that he may possibly have 

 incorrectly observed the palpi he described. It bears some re- 

 semblance to but is quite distinct from Natalis, Leai, Blackb. 



0. incertus, Macl. Not known to me. Probably a true Opilo. 



0. Pascoei, Gorh. A true Opilo. I have it from Victoria. 



0. sexnotatus, Westw. Not a true Opilo as it has finely granu- 

 lated eyes. I give it a new generic name (vide infra). 



0. variipes, Chevr. A true Opilo, apparently very close to 

 0. congruus, Newm. 



0. Whitei, Gorh. (apicalis, White). Unknown to me. I doubt 

 its being a true Opilo. 



Thus it appears that there are five known Australian species 

 confidently referable to Opilo and two doubtfully attributable to 

 it. 



NATALIS. 



N. debilis, sp. nov. Mas.? Elongata ; angusta ; sat parallela > 

 subtus sat sparsim pubescens ; supra pilis erectis elongatis 

 sparsis vestita ; nigra, pedibus an tennis et corpore subtus 

 picescentibus ; antennis sat elongatis sat gracilibus ; oculis 

 minus prominulis ; capite confertim subtilius subaspere 

 punctulato, puncturis paullo majoribus sparsim intermixtis ; 

 prothorace quam latiori ut 7 ad 5-|- longiori, ut caput punc- 

 tulato et ad latera nonnihil (fere ut JV. porcatae, Fab.) 

 ruguloso, sulco longitudinali mediano lineari sat elongato 

 impresso, pone medium utrinque fortiter dilatato-rotundato ; 

 scutello confertim subtiliter punctulato ; elytris ad apicem 

 inermibus, seriatim punctulatis, puncturis quadratis (antice 

 profundis sat magnis, postice gradatim minoribus minus pro- 

 funde impressis) ; interstitiis alternis leviter costiformibus ; 

 tibiis anterioribus 4 arcuatis ; abdomine sparsim subtiliter 

 punctulato, segmentis postice late membranaceo-marginatis ; 

 pedibus sat gracilibus, femoribus posticis perlongis ; tarsis 

 sat elongatis sat gracilibus. Long., 6^- 1.: lat., If 1. (vix). 

 At once distinguishable from all the previously described 

 Natales except porcata, Fab., by the close even punctu ration of 

 the entire disc of its pronotum and the feebleness of the lateral 

 rugulosity of that segment. From porcata it differs inter alia by 

 its black colour, by its distinctly less convex eyes, by its very 

 much more elongate prothorax, by the very evidently closer and
