margins flat, widest in the middle (where they nearly equal one-fourth the entire 

 width of the disc), narrowest behind ; disc smooth ; median line finely but deeply 

 impressed : scutellum smooth, somewhat curvilinearly triangular, but not pointed 

 behind : elytra not depressed behind the scutellum ; shoulders rounded, not chan- 

 nelled within ; regularly and finely sulcated (obsoletely so on the epipleurfB) ; 

 intervals sub-equal, scarcely convex, except at the apex : legs (especially the posterior) 

 strongly compressed and armed as stated in the preceding table : under-side shining 

 black ; femora dark green ; tibiae slightly rufescent, the four anterior a little bowed, 

 the hind somewhat contorted ; tarsi ferruginous ; antennae black. Long. 65 lines.

Caediothokax pithecius, Pascoe. 



The form of the proihorax is somewhat variable iu this species . 

 it is, however, almost coustautly widest before the middle, distinctly 

 more contracted behind than in front, the anterior contraction being 

 curved, the posterior nearly straight ; and the entire surface not 

 visibly punctured : the elytral sulcations are represented on the 

 epipleura? by faint punctured lines. 



The ^ is more elongate and slender than the $ , the elytra some- 

 what flattened at the base ; the front femora are armed with a broad 

 blunt tooth ; the anterior tibiae are very strongly bowed and furnished 

 on the inner edge with five or six short blunt spines. 



Cardiothoeax valgipes, sp. n. 



(? . Smaller and more slender than C. pithechcx, Pasc, and of a more decided 

 black colovu' : prothorax more convex, sides more rounded anteriorly, more strongly 

 conti'acted posteriorly : elytra more faintly striated, obsoletely so at sides, apex, and 

 on the epipleurae : the tooth to the anterior femora is narrower and more acute : the 

 ft'out tibiae are as strongly bowed, but are not spinose within. Long. 6| lines.

 $ . Unknown. 



CaBDIOTHORAX ERATERJfALIS, SJ). n. 



S . Unknown. 



? . Yery near to pithecius, Pasc, but a little stouter; the prothorax less convex, 

 broader, regularly rounded at the sides, widest at the middle, but little more con- 

 tracted posteriorly than anteriorly, disc distinctly fovoolated at each side the median 

 line. Long. 7^ lines. 



Queensland. 



Until both sexes of this species, and also of C. errnns, Pasc, are 

 known, I consider them of doubtful specific value.
