68 NOTES ON AUSTRALIAN COLEOPTERA, 



its widest part being evidently further fi'om the front and its sides 

 at this point being snbangulate. The anterior narrowing of the 

 prothorax as compared with the width at the base will at once 

 separate the present species from J), hrachinoderus, Chaud.

HOMETHES ANGULATUS, Sp.nOV. 



Oblongus; niger, antennis (basi testacea excepta) palpisque 

 fuscis, pedibus (geniculis et ad apicem sunimum tibiis 

 tarsorumque articulis infuscatis exceptis) mandibulisque 

 testaceis ; prothorace transversO; latitudine majori longe 

 ante medium posita, lateribus fortiter angulatis lineis binis 

 fere rectis formatis ; elytris sericeo-tesselatis, leviter striatis, 

 ad basin late rotundatim (quam H. sericei, Er., multo minus 

 fortiter) productis. [Long. 31, lat. \\ lines. 



Much like H. sericeics, Er. (which is said, probably correctly, 

 to be identical with I/, elegans, Newm.). Compared with it, the 

 present species is narrower and more parallel ; its prothorax 

 distinctly moi-e transverse, the greatest width nearer to the front, 

 the lateral margin formed by two nearly straight lines which meet 

 in an angle evidently more defined than the lateral angulation in 

 H. sericeus; the elytra very much less strongly produced forward 

 at the base. 



From H. guttifer, Germ., and marginipennis, Macl., the absence 

 of a pale elytral margin inter alia distinguishes this insect ; H. 

 emarginatus, Chaud., has joints 6-9 of the antennse white; ff. 

 micans, Germ., and velutinns, Macl., have the prothorax at its 

 widest at (or close to) the middle. Apart from colour, this species 

 is very near H. guttifer, Germ., but the prothorax is at its widest 

 a little nearer to the front, and has a more marked angle at its 

 widest point ; also the projected front of each elytron is sub- 

 angular, not evenly rounded. The colour difference has nothing 

 to do with sex.
