142 NOTES ON AUSTRALIAN COLEOPTERA, 



furnished at its apex with stout whitish bristles, apical joint 

 largest and thickly covered with such bristles. Prothorax cordi- 

 form, widest considerably in front of middle, anterior angles 

 prominent and obtuse; sides widely rounded and parabolically 

 constricted towards the base, posterior angles forming a slender 

 process directed backwards as in C. egerius Pasc; foliaceous 

 margins wide and slightly upturned, the anterior half separated 

 from the disc by a deep curved sulcus; border raised, not shining, 

 throughout, most evident at apex. Disc nearly flat, central line 

 distinct, an elongate foveate depression on each side. Elytra 

 elongate-ovate, shoulders obsolete, disc rather flat; striate, with 

 six striae on each elytron shallowly and indistinctly punctured; 

 intervals rough and obsoletely punctulate; margined by a strong 

 crenulate costa, roughl}^ punctured. Exterior to this costa, on 

 the curved side of each elytron, are two more rows of subfoveate 

 punctures separated from the true epipleura by a costate border less 

 elevated than the preceding but meeting it near the shoulder and 

 near the apex. Upper half of epipleurse with two similar ro"ws 

 of punctures to the two marginal series; lower half smooth. Legs 

 smooth, with under surface glossy black, femora unaruied. Body 

 beneath black, smooth and opaque. Dimensions — 14 x 5 mm. 



Hah. — ^Tambourine Mountain, Queensland; from Mr. R. Illidge. 



The above is, I believe, a female, but I have also a specimen, 

 which I take to be a male of the same species, given me by Mr. 

 Cox, bearing a label "Ex Coll. Froggatt," probablj'' from the 

 Tweed River district. This differs from the above in the follow- 

 ing particulars, which I therefore call var. A. 



Var.A. — Anterior angles of prothorax much more acutely and 

 squarely produced, as in C. egerius Pasc. Elytral sculpture less 

 distinct (possibly from abrasion and grease), with the outside 

 costa obsolete, and the inside or submarginal costa less strongly 

 marked. Dimensions — 121 x 4-2 mm. 



The above insects strongly resemble C . egerins Pasc, in colour 

 and form, especially in the peculiarly lobate hind angle of pro- 

 thorax; but they are clearly differentiated from that species in 

 size, and in the absence of the alternate costiform intervals on
