20 MESSRS. R. K. TURNER AND J. WATERSTON ON THE 



The locality given is Australia. 



The nervulus is distinctly postfurcal, not differing appreciably 

 from clavicorne in this res]5ect, in spite of Morley's statement to 

 tlie contrary. 



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



5 . Fulvo-ferruginea ; antennis supra nigro infuscatis, articnliti 

 13 apicalibus ferrugineis ; mandibulis dimidio basali, labro, 

 clypeo, facie, fronte lateribus, coxis trochantei'ibusque anticis^ 

 intermediisque, maculis duabus sub alis anticis, macula sub alis- 

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

 postscutello, segmento mediano fascia transversa post medium 

 coxam posticam attingente, tergitisque fascia apical i angustissima 

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

 apicali nigrescentibus ; alis subhyalinis, venis nigris, 



Long. 11 nnii. 



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

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

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

 fifth combined. 



Very similar to montivagum in other respects ; diflfering in the 

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

 of the tei'gites, and the less prominent basal teeth of the petiole. 



Hah. Hobart, Tasmania; summer 1891 {J. J. Walker). 



Might easily be mistaken for montwaguon^ but the structural 

 diflerences in the mandibles and antennas 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 

 supi-a, tarsisque posticis, basi anguste ferrugineis, nigris; alis 

 hyalinis, iridescentibus, venis nigris. 

 Long. 8 mm. 



5 . Clypeus a,nd face sliining. very sparsely punctured, face 

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

 fulvous, somewhat infuscate above to beyond the middle, the 

 third joint a,bout half as long again as the foiu^th, 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 sparsely punctured anteriorly \ 

 notauli rather short ; .mesopleura; smooth on the upper half, 

 sparsely and finely punctured on the lower half ; epimeial sulcus 

 finely crenulate throughout. Median segment with the apical 

 . cmna 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
