144 REVISION OF THE THYNNIDiE OF AUSTRALIA, II., 



produced at the apical angles of third and fourth segments, pro- 

 duced into a long acute spine at the apical angles of the fifth 

 segment. Hypopygium lanceolate, without an apical spine. 

 Hab.—Swa,n River, W. A. (Smith). 



Var. orientalis, n.var. 



(J. A delicate longitudinal carina from base of clypeus half 

 way to anterior ocellus. Clypeus entirely black. The yellow 

 marginal bands of the pronotum united and narrowly interrupted 

 in middle; the yellow spots on abdomen much smaller than in 

 the typical form. 



This variety is a little larger and more robust than the type,, 

 and appears to be constant. 



Hab. — Wimmera, Vic. (French). 



71. T. (Aeolothynnus) doddii, n.sp. 



(J. Cl} T peus not much advanced, broadly and slightly emarginate 

 anteriorly; labrum exposed, feebly bilobed; a faint depressed 

 transverse line on clypeus before apex. Head delicately and 

 very closely punctured; thorax more sparsely punctured, the 

 punctures larger than those on head. Pronotum depressed, th& 

 anterior margin raised, a little narrower than head. Scutellum 

 rather broadly truncate at apex ; median segment smooth. 

 Abdomen narrow, flattened, the segments of about even width, 

 strongly depressed at base of each segment; second and third 

 segments with a strongly raised mark, emarginate in centre, just 

 before apical margin. Hypopygium subtriangular, narrowly 

 truncate at apex, with a short apical spine. Segments 2-5 

 strongly produced at apical lateral angles beneath, fifth produced 

 into a long spine on each side. Black; mandibles, except at apex, 

 clypeus, margins of eyes, narrowly interrupted at apex, a broad 

 band above base of antennas, narrowly interrupted in middle, pro- 

 notum with the exception of a small black spot in middle and a 

 transverse line on each side, a large square spot on posterior 

 margin of mesonotum, a curved line above tegulae, tegula?, meso- 

 pleurse, a large spot on scutellum, and a spot at the anterior
