then strongly curved to apex, where each is rather nar- 

 rowly notched, with the apical projection rather longer 

 than the other; near apex with a strong projection 

 (almost as long as the portion of mandible in front of it) 

 somewhat curved, and directed upwards and inwards. 

 Prothorax slightly wider than head, sides smooth and 

 parallel for most of their length, hind angles widely 

 rounded, apex very feebly rounded in middle; sides and 

 base with dense and rather coarse punctures, elsewhere 

 with sparse and minute ones. Elytra with shoulders 

 rounded ofT; with dense and comparatively small punc- 

 tures; striation and interstices fairly distinct. Length, 

 17 mm. 



Female unknown. 



Hab. — Tasmania (F. A. Rodway). 



A very distinct species, although somewhat resem- 

 bling the preceding at first sight; but the mandibles are 

 very different about the apex, the labrum is pointed in 

 the middle, the head is without conspicuous tubercles 

 above the eyes, and the sides in front of the eyes are 

 largely scooped out, and with the disc marked off from 

 the sides by abrupt and slightly overhanging walls. The 

 head of the type, measured along its middle, is longer 

 than its prothorax, and its punctures, except at the sides, 

 where, ho\\ever, they are very confused in parts, are very 

 small. The upper tine of each mandible is much more 

 conspicuous than on either the preceding or following 

 species. The two front teeth of the front tibiae are of 

 normal size, 1)ut the others are rather smaller than usual. 

 The coarse punctures on the prothorax are all submar- 

 ginal, but there are a few of moderate size about the 

 middle slightly in advance of the base. 



A smaller (15 mm.) specimen differs from the type in 

 having the head considerably smaller, with the frontal 

 slope and the punctures much more conspicuous, the 

 mandibles stouter and shorter, with their sub-basal pro- 

 jections more obtuse, but the tips and the upper tines 

 are the same, except that they are somewhat smaller; the 

 prothorax is smaller, with the sides more rounded; the 

 elytra have smaller punctures, and the front tibiae have 

 more and stronger teeth..
