Galbocerus, n. g. 



Head convex, antennary sockets large, not closely 

 approximated; clypeus trisinuate in front. Antennae flabel- 

 late. Prothorax moderately transverse. Elytra parallel- 

 sided to beyond the middle. Prosternum with a wide and 

 deep excavation on each side of base; proplenral triangles 

 each margined inwardly by a distinct carina, extending from 

 front coxa to level with the middle of the eye, margined out- 

 wardly by the overhanging side of pronotnm. Metasternum 

 with two side pieces on each side, the onter one (the trne 

 episternnm) rather thin and parallel-sided, the inner one 

 hooked at base and narrowed till it disappears slightly before 

 the apex. Hind coxae long inwardly, strongly and evenly 

 narrowed (almost to a point) outwardly; tarsi with fourth 

 joint wide and strongly produced on lower-surface, claws each 

 with a wide and conspicuous membranous appendix. 



The type and only specimen in the Museum is, in general 

 appearance, strikingly like Microrhagus cairnsensis on an 

 enlarged scale, but it differs from Microrhagus in having 

 propleural triangles instead cf parallelograms, in the pro- 

 sternal and metasternal sutures, tarsi, etc. Galbodema has 

 wide and deep prosternal sulci. Galba has deep prosternal 

 sulci and very different tarsi. No other Australian genus 

 has been recorded as having species with flabellate antennae. 

 The flanks of the pronotum are overhanging, so as to provide 

 protection for the antennae when at rest (much as on Phaeno- 

 cerim clavicornis), but as the propleural triangles are flat up 

 to (although polished near) the overhanging margins the 

 presternum cannot be regarded as having lateral sulci (as in 

 Galba, Galbodema, etc.) ; there is, however, a wide and deep 

 excavation on each side at the base for the reception of the 

 femur. The head of the type being closely applied to the 

 breast, with the palpi partially concealing them, I have not 

 been able to see if the hind edge of the mandibles is strongly 

 sinuous, but believe it to be so. Regarding it as such, the 

 genus, in Blackburn's table, would be associated with Hypo- 

 coelus, from which it differs in the antennae, tarsi, and meta- 

 sternum. Regarding it as belonging to CC of that table, it 

 would be associated with Eiiwen.es f , which has very different 

 sides of prosternum, metasternum, antennae, and claws. I 

 am dubious as to its correct position, but provisionally it may 

 be placed near Phaenocerus. 



Galbocerus parallelus, n. sp. 



Piceous-brown (almost black), antennae and legs of a 

 dingy-red. Rather densely clothed with short, stramineous 

 pubescence.
