182 REVISION OF THE THYNNIDiE OF AUSTRALIA, II., 



strongly depressed transverse line near base. Epipygium rugose 

 at apex; abdomen beneath rugulose. Hypopygium with a stout 

 spine on each side near basal angles, thence sharply narrowed 

 and produced with parallel sides, narrowly rounded at the base 

 of the strong apical spine. Anterior coxa? strongly hollowed. 

 Black; the pubescence thin and cinereous. Anterior margin of 

 clypeus, mandibles except at apex, and a minute spot on each 

 side above base of antennae yellow. Legs, except coxse, and 

 tegula? ferruginous. Wings flavo-hy aline, nervures fuscous. 

 Length 22 mm. 



£. Clypeus with a carina from base. Head much broader than 

 pronotum, only slightly convex, strongly rounded posteriorly, 

 shining, almost smooth on vertex, finely punctured on front, with 

 a short longitudinal sulcus between antenna?. Pronotum much 

 broader than long, closely and finely punctured, not much 

 narrowed posteriorly, anterior margin slightly arched, with a 

 few large punctures from which spring long hairs. Mesonotum 

 finely punctured, broadly rounded posteriorly. Median segment 

 short, narrower than pronotum, obliquely truncate posteriorly, 

 coarsely and sparsely punctured, surface of truncation shagreened. 

 Abdominal segments sparsely punctured, smooth at base; first 

 segment with apical margin raised and a groove before it, giving 

 the appearance of a transverse carina before apex; second seg- 

 ment with seven or eight transverse carina?, including the recurved 

 apical margin, carina? near base more or less irregular; apical 

 half of fifth ventral segment longitudinally rugose. Pygidium 

 longitudinally striated, oblique, not very narrow, sides parallel, 

 epipygium narrowly rounded at apex, suddenly narrowed just 

 before apex, leaving sharp angles. Black; legs and mandibles, 

 except at apex, ferruginous; antenna? fusco-ferruginous.
