a row of widely placed punctures (of same size as the usual dis- 

 coidal punctures) extending from the anterior to the apical dis- 

 coidal punctures, but placed on a line about one millimetre nearer 

 the suture than the anterior discoidal puncture. There are five 

 punctures in the row on the left elytron, and three on the right; 

 their presence is probably abnormal.

I have already suggested the likelihood of all the above 

 synonymy, and a recent examination of the types in the Macleay 

 Collection of C. suirugosulum, C. suhstriatulum, C. glaherrimumy 

 and C, undidatutn has convinced me of their identity with 

 Eutoma tinctilatuin, Newm. The type of Eutoma mastersi, 

 MacL, is not in the Macleay Collection, but I think it unlikely 

 that it will prove different from C. tinctiUatum. 



Trichocakenum castelnaui, n.sp. 



/J. Elongate, cylindrical, laevigate. Head large; three supra- 

 orbital punctures on each side; suborbital channel short, wide, 

 not longitudinally divided by a median ridge : prothorax longer 

 than broad, each lateral channel with six setigerous punctures : 

 elytra oval; inflexed lateral margin narrow behind first ventral 

 segment; a longitudinal row of six or seven widely placed punc- 

 tures on each elytron at about the external third of its width : 

 anterior tibiae bidentate. Black, shining. 



Head large, convex (3-8 mm. across ej^es); frontal sulci long, 

 deep, diverging lightly backwards and reaching to opposite base 

 of orbits; intermediate angles of clypeus short, dentiform; eyes 

 deeply set in orbits, depressed; orbits prominent, postocular
