364 REVISION OF THE AMYCTERIDES, ti., 



T. incanescens in the Australian Museum, and comparison with 

 the type of T. muricatus, have led me to regard the latter as at 

 least worthy of varietal rank. 



Talaurinus rugifer Boisduval. 



Boisd., Voy. de 1' Astrolabe, ii., p.378; Macl., I.e., p.236; T. 

 excavatus Bohem., I.e., p 54; Macl., l.c , p.236. 



(J. Elongate-elliptical, convex, robust, Black, in cavities 

 sparingly squamose; setae small, black. 



Head large, convex, forehead concave. Rostrum deeply ex- 

 cavate; external ridges prominent, convergent slightly and con- 

 tinued on to forehead; internal ridges almost obsolete, repre- 

 sented by two elevations in the depth of the excavation. Scrobes 

 open behind, continued almost to eye; eyes large, ovate. Antennae 

 moderately long, club hardly pedunculate. Prothorax(7 X 8 mm.) 

 strongly rounded on sides, apical sinuosity feeble; disc feebly 

 depressed, granules minute, rather closely set; sides granulate. 

 Elytra (16-5 x 9 mm.) elongate, subparallel; base strongly arcuate, 

 apex rounded, humeral angles with a small nodule; disc with 

 three double rows of moderately large, rounded, foveiform punc- 

 tures, the intrastrial partitions not raised; interstices prominent, 

 costiform, sutural slightly raised on declivity and near base, 

 second very prominent, straight; third humeral; fourth lateral, 

 well denned, and ending on sides of declivity; costse with minute, 

 obsolete, setigerous granules; sides with rather larger punctures, 

 the interstices more granular. Beneath, with a brownish vitta; 

 intermediate segments long; fifth not excavate. Anterior femora 

 with a median tooth beneath, also rather closely granulate. 



9. Differs from male in its more ovate shape; in the elytra more 

 produced and strongly mucronate; and in the absence of the 

 femoral tooth. Dimensions : (J.25 x 9; 9. 25 x 9 mm.

In ascribing the names T. rugifer and T. excavatus to the 

 present species, I am following Macleay's identification; in the 

 Macleay Collection, the male stands under T. rugifer, and the 

 female under T. excavatus. I believe these names to be correct; 

 of excavatus, Bohemann says : ' ' apice emarginata, non-
