Chaudoir, in his Monograph, gave the name of C. Iceteviridis 

 to the Australian species which Castelnau had taken for C. 

 marginatus Dej.; and, at the end of his note, says C. darling- 

 f-.nsis is only a specimen with lightly convex interstices. Seeing 

 that one of Castelnau's names is valid according to the rules of 

 nomenclature, there seems to have been no reason for a new 

 name from Chaudoir. 



Tribe Oodini.

Some species of the tribe Oodini have two supraorbital 

 punctures on each side of the head. I have noticed this character 

 only in Anatrichis australasicH Chaud., A. pusilla SI., A. sex- 

 striatis SI., Oodes modesties Cast., 0. impressus Chaud., and 0. 

 bostocki Cast. The hind puncture is placed above the posterior 

 third of the eye, and bears a fully developed tactile seta; this 

 puncture and seta are invariably present throughout the tribe 

 Oodini. The otlier puncture, whicii I have noticed onlj' in the 

 species mentioned above, is small, shallow, and without a seta 

 (only once, in a specimen of 0. modestus, have I noticed a 

 minute setule in this puncture, on one side of the head). The 

 presence of this small i)uncture, in these few species, must be 

 considered a rudimentary character, indicating that the Oodini 

 are descended from a stem which had two supraorbital punctures; 

 and, if due weight be given to this clue of origin, the view of 

 Chaudoir, that the Oodini are a tribe coordinate with the 

 Chlaeniini, must be upheld against G. H. Horn's idea, that the 

 Oodini were only a subtribal division of the Chlaeniini. This 

 tribe may be briefly defined as follows : — 



Head with one fully developed supraorbital seta rising from 

 a puncture above posterior third of eye(rarely a second non- 

 setigerous puncture is present above anterior third of eye). 

 Mandibles without a setigerous puncture in outer scrobe. Pen. 

 ultimate joint of labial palpi without tactile .setae. Prothorax 

 glabrous; posterior socketdiole not fringed with hair above
