and Gyriiiidtc of Austmlasia. 407 



the apex ; the colour is ferruginous, with very irregularly formed dark- 

 fuscous markings, so irregular that, of the large series before me, hardly 

 two examples entirely agree with each other; the ordinary typical 

 pattern woidd seem to be two large medial irregular markings of black, 

 occupying nearly the wliole breadth of the elytra, and a transverse 

 fascia below them, close to the apex ; in some examples these two 

 medial markings become a transverse band hardly interrupted at the 

 suture, in others they are (more or less broadly) connected with the 

 apical fascia ; in other examples the whole posterior part of the elytra 

 is (with the exception of the extreme apex) fuscous black, while 

 (that no form of marking might be absent from the species) one ex- 

 ample has, from the apex to the base, longitudinal instead of transverse 

 markings ; in most instances the anterior surface (with the exception 

 of the suture) and the apex are rufo-ferruginous : abdomen and under- 

 side tliickly punctate, in colour rufo-ferruginous : le(/s and antemxs 

 rufous. 



Apparently as abundant as it is a variable species in the south of 

 Australia. Taken near Adelaide and at Melbourne. In the col- 

 lections of the British Museum, Mr. Bakewell, Mr. Waterhouse,

2, H. hamatus, n. sp. 



H. ovatus, latus, glaber, punctatus, rufo-fuscus ; thorace rufo, ad basin 

 fusco; elytris obsolete imistriatis, ad latera et suturam (et apud 

 medium plerumque obsolete) longitudmaliter flavo notatis ; pedibus et 

 antennis rufo-testaceis.

Long. corp. 2|-3 lin., lat. l^-lf lin. 



Ovate, broad, impubescent, thickly punctate, or rufo-fuscous : head 

 large, at the inner and lower margin of the eyes is an obsolete circular 

 depression, the surface is very sparingly punctate and rufous : thorax 

 broadly transverse, the lateral margins are constricted in front, the 

 anterior margin somewhat excavated, the surface is thickly pmictate 

 (more distinctly towards the base), in colom* rufous, the posterior margin 

 (and also more narrowly the anterior) being fuscous : eli/tra ovate, 

 somewhat narrowed near the shoulders, thicldy punctate throughout, 

 less distinctly so near the margins; an obsolete but well-defined lon- 

 gitudinal stria may be discerned (when viewed obliquelj-) at some 

 distance from the suture ; the smface is sparingly pubescent towards 

 the sides and base ; along the line of the margin is a broad suihised 

 rufous marking, extending longitudinally in some examples nearlv to 

 the apex; near the suture is another longitudinal flavous marlring, 

 which in most instances does not extend from the anterior margin be- 

 yond the middle ; between these two a third marking may occasionallv 

 be traced, narrower and less distinctly defined : abdotnen and tindei-- 

 side fuscous, the apex being rufous : legs and antemue rufo-testaceous.
