226 REVISION OF THE THYNNID^E OF AUSTRALIA, II., 



above, rather narrowly truncate at apex. The segments without 

 an impressed transverse line near base. Hypopygium short, with 

 blunt projections near basal angles, thence gradually narrowed, 

 shortly produced, subacute at apex, but without an apical 

 spine. 



Hab. — Swan River(Smith). 



Smith compares this species with T. melleus Westw., giving the 

 chief points of difference, except the absence of an impressed line 

 on the abdominal segments. He says that the hypopygium is 

 truncate at the apex; this is the case in the type, but only through 

 injury. 



180. T. frknchi, n.sp. 



(J. Clypeus produced and broadly truncate anteriorly, convex, 

 shallowly punctured and connected with interantennal prominence 

 by a narrow carina. Head rugulose on front, finely and closely 

 punctured on vertex. Antennae stout, rather shorter than head 

 and thorax combined. Thorax finely and closely punctured; 

 disc of mesonotum and scutellum more coarsely and sparsely 

 punctured; scutellum subtriangular, rather long, narrowly trun- 

 cate at apex, prominent, with a depressed transverse line at base. 

 Median segment depressed, rounded at sides, very finely and 

 closely punctured, with thin, short, grey pubescence. Abdomen 

 elongate, rather closely punctured above, finely and very closely 

 punctured beneath; basal segment oblique anteriorly; segments 

 2-5 with a slightly impressed transverse line near base; epipj'gium 

 rugose. Hypopygium projecting very little beyond epipygium, 

 showing from above only a short lanceolate spine. Black; man- 

 dibles except at apex, clypeus, margins of eyes interrupted on 

 vertex, posterior margin of pronotum, tegulse, apex of femora, 

 tibiae above, tarsi, a band narrowly interrupted in middle near 

 apical margin of the six basal abdominal segments, the breadth 

 of the bands occupying about one-third of the length of the seg- 

 ments, and a spot on each side of the same segments beneath 

 yellow. Markings of the abdomen of a very pale colour. Wings 

 flavo-hyaline, nervures fulvous. Length 20 mm. 



Hab.— Melbourne(French). Allied to T. melleus Westw.
