132 RE VISIONAL NOTES ON AUSTRALIAN CARAIIIDJ:, IL, 



ocular processes; postocular part of orbits rising decidedly but 

 roundly from head, not forming anteriorly a thick border to 

 external part of eyes; one supraoibital puncture on each side.* 

 Prothorax convex, a little longer than broad (7x65 mm.); lightly 

 rounded on sides, sinuate-angustate to base; anterior margin 

 truncate; border not the least advanced at anterior angles; lateral 

 margins bipunctate, posterior puncture a little before posterior 

 sinuosity, anterior (double on both sides in specimen before me) 

 near apex — about 1-6 mm. behind anterior angle. Elytra long 

 (14-5 X 6-7 mm.), laevigate, depressed along suture; base of each 

 elytron with a wide strongly raised oblique ridge rounded on 

 summit, these ridges rather widely separated from one another 

 by the sutural depression; a row of ocellate punctures along- 

 posterior side of each ridge in a slight depression; el3'tra united 

 at apex to form a rather prominent triangular projection; lateral 

 borders becoming wide and thick posteriorly, divided from one 

 another at apex by the apical prominence ; a dentiform pro- 

 minence behind each humeral angle. Prosternum with inter- 

 coxal part impunctate and gently declivous to base. Ventral 

 segment and posterior coxee impunctate. Length 28, breadth 

 6*7 mm. 



Hab. — W.A.: Roebuck Bay (Coll. French; unique). 



The larger size and black colour at once distinguish it from 

 other described allied species. There is a faint suspicion of a 

 bluish tinge on the sides of the elytra, so that I should expect 

 this species to be somewhat variable in colour, perhaps in some 

 localities showing a tendency to become violaceous. 



I consider the species before me to be T. macros, Bates, but 

 would call attention to the following characters in the original 

 description as presenting differences : — 



"Head broader than the thorax" — I believe Bates to have 

 made this statement from the appearance of these parts; to the 



" There is a single puncture on the right side, and two closely placed on 

 the left — evidently a case of the duplication of single setigerous punctures so 

 frequently met with throughout the Carenides.
