Collection from Mulwala, N. S.W., in which the clypeus is wholly 

 yellow, and with the carina only visible on the extreme base. 



Q. I have examined several females which I believe to be 

 correctly assigned to this species, and find much variation in the 

 number of carina? on the second abdominal segment. The carinse 

 are slightly broken and irregular, but vary in number from seven 

 to about twelve. As the specimen with only seven carinse has 

 also a spine on each side of the pygidium slightly developed, it 

 may prove to be distinct; but in other specimens the number of 

 carina is intermediate. In reference to this variation I may 

 refer to my remarks on T. apterus Oliv, 



Rob. — Victoria; Woodford, Blue Mts.(Waterhouse), Mulwala, 

 ». S.W.(Froggatt). 



122. T. (Lophocheilus) laeviceps Sm. 



Thynnus laeviceps Sm., Cat. Hym. B.M.vii.p.44,n.l24,1859(9). 



£. Extremely near T. obscurus Klug, but the head is a little 

 smaller and flatter, and the raised apical margin of the second 

 abdominal segment is separated more widely from the transverse 

 carina? before it. 



Hah. — Australia (Smith). Said to come from the North or 

 N.W. Coast. 



123. T. (Lophocheilus) froggatti, n.sp. 



(J. Clypeus advanced and rather narrowly truncate anteriorly, 

 punctured and clothed with long cinereous pubescence, with a 

 strong carina from base to apex. Head very finely and closely 

 punctured, interantennal prominence very broad and bilobed; an 

 almost obsolete, interrupted carina from below the anterior ocellus, 

 not reaching base of clypeus. Thorax very finely and closely 

 punctured; median segment delicately rugulose, rounded and 

 depressed. Abdomen fusiform, very finely punctured, segments 

 almost smooth at their base; first segment oblique anteriorly, 

 with a longitudinal sulcus from base not reaching apex; beneath 

 the segment is obliquely truncate at apex, leaving a deep space 

 between first and second segments. Segments 2-5 above with a
