MESSRS. R. E. TURNER AND J. WATERSTON ON THE 



The locality given is Australia, 



The nervulus is distinctly postfiircal, not differing appreciably 

 from clavicorne in this respect, in spite of Morley's statement to 

 the contrary. 



Labium hobartense, sp. n. (Text-fig. 6, h.) 



5 . Fulvo-ferrnginea ; antennis supra nigro infuscatis, articulis 

 13 apicalibus ferrugineis ; mandibulis dimidio basali, labro, 

 clypeo, facie, fronte lateribus, coxis trochanteribusque anticis 

 intermediisque, maculis duabus sub alis anticis, macula sub alis 

 posticis, macula supra coxas intermedias, sulco epimerali, scutello, 

 postscutello, segmento mediano fascia transversa post medium 

 coxam posticam attingente, tergitisque fascia apicali angustissima 

 flavis ; petiolo, area juxta-coxali, tarsisque posticis articulo 

 apicali nigrescentihus ; alis subhyalinis, venis nigris, 



Long. 11 mm. 



5 . Mandibles bidentate (text-fig. 6, 6), rather short ; face 

 shining, sparsely and finely punctured, broader than long. An- 

 tenna3 42-3ointed, third joint a little shorter than the fourth and 

 fifth combined. 



Very similar to niontivagum in other respects ; differing in the 

 yellow band on the median segment, in the yellow apical bands, 

 of the tergites, and the less prominent basal teeth of the petiole. 



Hah. Hoba.rt, Tasmania; summer 1891 {J. J. Walker). 



Might easily be mistaken for montivagimi, but the structural 

 diflerences in the mandibles and antennse distinguish it at once. 



Labium associatum, sp. n. 



$ . Fulvo-ferruginea ; mandibulis, apice nigris, labro, clypeo, 

 facie, scapo subtus, orbitis, scutello, macula sub alis anticis, 

 mesopleuris antice' macula., coxisque trochanteribusque anticis 

 intermediisque flavis ; scutello sulco basali, tibiis posticis apice 

 supra, tarsisque posticis, basi anguste feirugineis, nigris ; alis^ 

 liyalinis, iridescentibus, venis nigris. 



Long. 8 mm. i : . 



5 . Clypeus and face shining, very sparsely punctured, face 

 much broader than long ; mandibles simple. Antennae 36-jointed, 

 fulvous, somewhat infuscate above to beyond the middle, the 

 third joint about half as long again as the fourth, the fifth 

 distinctly shorter than the fourth. Eyes very feebly sinuate 

 opposite the base of the antennae ; front and vertex shining, 

 almost smooth, with a few minute punctures, Mesonotum shining, 

 almost smooth, the median lobe sparsel}^ punctured anteriorly ;^ 

 notauli rather short; mesopleurje smooth on the upper half, 

 sparsely and finely punctured on the lower half ; epimeral sulcus, 

 finely crenulate throughout. Median segment with the apical 

 cirina of the basal area broadly interrupted in the middle; areola 

 not separated from the petiolar area, the dividing carina only 

 feebly indicated at the sides, areola smooth in the middle, finely
