284 THE GENERA AND SPECIES OF AMYCTERIDiE, 



The elytra are striate ou the back with a row of granules 

 between each stria, while towards the sides the\ are rugose and 

 less regularly marked. 1 n addition to tliese rows of granules 

 there are three rows of tubercles, minute in front and increasing 

 in size towards the apex ; the fii'st of these rows shows scarcely 

 any tubercles towards the base, but ternainates in a large pointed 

 one, which is nearer the suture than the rest of the series. The 

 apex of the elytra is slightly mucronate and dehiscent. The 

 female differs from the male in being longer, broader, and less 

 strongly tuberculate. 



21. AOANTHOLOPHUS SPINIFER. 



Oblongus subangustus niger parce cinereo-squamosus, fronte 



escavata, crista bidentata dente posteriore acuto anteriore 



rotando, thorace bifariam tnberculato lateribus dentato, 



elytris seriatim punctatis trifariam tuberculatis tuberculis 



values acutis. 



Long. 7i lin., lat. 21 lin. 



Hab. Victoria. 



I have only one specimen of this insect, apparently a male ; 



it is of elongate form, and of a deep black hue, with minute 



ashen coloured scales. Tlte foreliead is excavated. The crest is 



deeply bilobed, the anterior lobe slightly pointed and rounded in 



front, the posterior longer and pointed backwards. The apex 



of the lateral margins of the rostrum is much elevated. The 



thorax has a row of five tubercles on each side of the medial 



line, the posterior one being long and obliquely placed, and two 



strong pointed tubercles on each of the sides, one near the 



middle, with a smaller one on its anterior face ; the other near 



the base. The elytra are not broader than the thorax, and are 



marked with rows more or less regular of somewhat distant 



punctures, with three or four small tubercles near the base on 



each side of the suture. They have also each three rows of 



strong pointed tubercles, the external row consisting of four 



large tubercles and a smaller humeral one. The space near the 



suture between the first row of tubercles on each side has a 



yellowish tinge from the minute scales which cover the elytra
