^. Mesopleurse red. Otherwise the male is so close to T. 

 gracilis Westw., that I am inclined to think they may prove to 

 be identical when long series are studied. Anterior angles of 

 pronotum strongly produced. 



9. The head is a little longer and narrower than in the speci- 

 mens of T. gracilis that I have seen. 



Head longer than broad, slightly rounded at posterior angles, 

 sparsely punctured. Pronotum about twice as broad as long, 

 almost smooth, with a row of setigerous punctures along anterior 

 margin; mesonotum not much narrowed. Median segment strongly 

 punctured, obliquely truncate posteriorly. First abdominal 

 segment very coarsely punctured, depressed and almost smooth 

 .at apex, leaving a raised transverse carina before apical margin. 

 Second segment with five transverse carinse, not including the 

 slightly raised apical margin; the remaining segments rather 

 sparsely punctured. Fifth ventral segment rugose. Pygidium 

 lanceolate, raised into a narrow carina at base, the carina branch- 

 ing narrowly towards apex. Dull f usco-ferruginous, the abdomen 

 black. Length 10 mm. 



Hab. — Sydney (Froggatt; <JQ in cop.).
