atis; labro clypeum sat late superanti; antennis 8-articulatis; 



coxis posticis ad latera quam metastemum parum brevioribus, 



quam segmentum ventrale secundum sat longioribus ;

This species belongs to my section III., group V., sub-group 



II. (vide Proc. Linn. Soc, N.S.W., 1889, tabulation pp. 141 — 



14.5), and in the tabulation would fall alongside //. cygneus, from 



wliich it differs by its much larger size, darker colour, more 



coarsely punctulate elytra, and wider more robust build ; on the 



underside the ventral segments are considerably more sparsely 



punctulate, especially in the middle ; the basal joint of the hind 



tarsi is considerably shorter, scarcely exceeding half the length of 



the second joint.

 The clvpeus has a well-defined elevated margin all across its 

 front, which is oidy very widely (and scarcely distinctly) emargin- 

 ate. 



This is one of the few species of Jleteronyx which seem to 

 to oscillate between Sections II. and III. in my arrangement of 

 the genus, the labrum rising fully to the level of the clypeus, but 

 scarcely protruding above it. However, as, from a certain point 

 of view, the head has some feeble appearance of a "trilobed out- 

 line," or rather of its curved outline being narrowly bulged out 

 in the middle, I think it is best placed in Section III. ; and if so 

 placed it will fall in Group VI., which is tabulated in Proc. Linn. 

 Soc. N.S.W., 1889, pp. 426-8. In that tabulation its place 

 wall 'be beside //. rotundifrona, Blackb., to which it appears to 

 me genuinely allied, although differing from it much by the close, 

 even puucturation of its head, the much finer and feebler
