184 REVISION OF THE THYNNIDjE OF AUSTRALIA, II., 



interrupted by a broad black V-shaped mark, a curved line on 

 each side of abdominal segments 3-5 near apical margin and 

 legs ferruginous-brown. Length 16mm. 

 #a6.— Cumberland County, N. S.W. 



125. T. (LOPHOCHEILUS) TUBERCULIVENTRIS Westw. 



Thynnus tuberculiventris Westw., Arc. Ent. ii. 2, p. 118, P.76, 

 fig.2, 1844(£). 



This species may be distinguished from T. crinitus by the less 

 strongly fusiform abdomen, which is also closely and shallowly 

 punctured instead of smooth and shining; and by the presence 

 of a small tubercle on each side of the second ventral segment 

 close to the apical margin. Length 20 mm. 



I have received a female with this species which can only be 

 distinguished from that of T. rufiventris by the shape of the 

 pygidium, the sides of which are not parallel but convergent 

 towards the rounded apex. But it is possible that the pairing 

 is inaccurate in this case. 



Hab. — Albany, W.A.; Victoria( French). 



126. T. (Lophocheilus) crinitus, n.sp. 



(J. Clypeus moderately produced and rather broadly truncate 

 at apex, only slightly convex. Head, thorax and median segment 

 finely rugulose, clothed with fulvous pubescence on head and disc 

 of thorax, with grey pubescence on median segment and on thorax 

 beneath. Pronotum as broad as head, broadly emarginate 

 anteriorly, with prominent angles. Median segment rounded, 

 depressed from postscutellum. Abdomen fusiform, shining, with 

 a slightly impressed transverse line near base of segments 2-5. 

 Epipygium strongly punctured at base, with a few curved striae 

 at apex. Hypopygium with a rounded prominence on each side 

 at basal angle, thence triangular to base of the acute and slightly 

 recurved apical spine. Black; mandibles except at apex, anterior 

 margin and sides of clypeus, a large spot on each side of all the 

 dorsal segments of abdomen and of all except basal ventral seg- 

 ments orange; legs, except coxae, ferruginous. Length 29 mm.
