within at the apex, intermediate and posterior femora dentate 

 near apex, that on the posterior much the larger and lobate, 

 anterior tibise sb'ghtly bowed, intermediate and posterior tibiae 

 nearly straight. 



5. Differs from the male in having thinner and undentate 

 femora, the antennae shorter, and the posterior tibiae quite straight.

Hah. — Dorrigo, New South Wales. 



Two specimens; the sexes were taken, by the author, in July 

 of the present year. This species differs from, though most 

 closely allied to, C, femoratus Bates, in the following characters : 

 Size larger, colours more brilliant, especially on pronotum and the 

 foliate margins thereof, and particular in the strongly dentate 

 hind angles of prothorax and the antecedeyd sinuationof the sides. 

 The tooth on the posterior femora, though laige and lobate, is 

 not so prolonged in my specimen as in specimens of C. femoratus 

 Bates, from the Tweed and Yarrow Creek districts. 



Cardiothorax iridipes, n.sp. (Fig. 2.) 



Elongate-ovate, dark purple-bronze, nitid, pronotum with violet 

 reflections, underside nitid black, femora and tibiae iridescent 

 purple and cyaneous, antennae and tarsi piceous. 



Head with labrum prominent, narrow and truncate, epistoma 

 convex, wide, a little raised at sides, minutely and closely punc- 

 tate, forehead with impression squarely truncate and deeply 

 indented in front, rounded behind, with about six large punctures 

 thereon; antennae 4| mm. long, joints 3-7 elongate-obconic, third 

 longer than fourth, 8-11 successively but only slightly wider and 

 shorter, eleventh ovoid-acuminate. Prothorax 3 x 3^ mm., wider 

 at apex than at base, greatest width in front of middle, apex 

 slightly concave with obtusely rounded anterior angles scarcely 

 prominent, sides slightly rounded in an even curve till near base, 

 then rather abruptly sinuate and deflexed at the posterior angles, 

 these forming a subrectangular tooth a little twisted downwards 

 and outwards; base truncate; foliaceous margins narrow, sub- 

 horizontal, widest at middle, the separating discal line nearly
