7-l! [September, 



CaRDIOTHOEAX CnALCETJS, Sj). n. 



Similar in Tialit to C. Howitti, Pascoe, but smaller, the hind angles of pro- 

 thorax not produced nor prominent ; the elytra moi'e convex, the sides and epipleurse 

 more gradually rounded and more strongly sculptured, and the front tibiae neither 

 incrassated nor strongly compressed. 



(? . Unknown to me. 



$ . Brilliant bronzed-brown : head sti-ongly foveated between the eyes ; pro- 

 thorax very minutely punctulate, but little convex, widest before the middle, very 

 finely bordered at base and apex, sub-obsoletely so at the middle of the latter ; sides 

 strongly bordered, this border thickening posteriorly ; foliaceous margins in their 

 widest j^art equal to one-fourth the width of the entire disc ; this latter irregularly 

 foveate at each side the median line (which is faintly impressed), and on the middle 

 near the base, these foveas being marked by several irregular impressed points ; base 

 sub-sinuately emarginate : elytra depressed behind the scutellum, shoulders rounded, 

 regularly sulcated, intervals slightly unequal, 5 and 7 slightly broadest ; under-side 

 and legs shining black, tarsi rufescent, antennte fuscous : femora unarmed ; tibiae 

 straight. Long. 8 lines. 



Queensland. 



Caediotiiorax ceassicoe^s^is, sp. n. 



$ . Elongate, narrow, cylindric ; black or bronzed-black : head and prothorax 

 minutely punctulate ; the usual impressions on the former strongly marked, more or 

 less strongly foveated between the eyes : prothorax quadrate ; sides sub-parallel at 

 the middle, more strongly, abruptly, and obliquely contracted at base than at apex, 

 unequally bordered, being thickest anterioi'ly, broadly channelled ; apex rather 

 deeply emarginate, front angles acute and prominent ; base sinuately truncate, hind 

 angles obtuse, not prominent ; base and apex entirely bordered ; disc rather convex, 

 uiiifoveate at each side the median line (which is finely but deeply impressed), or not : 

 elytra rather finely sulcated ; the intervals equal, smooth, and flat, the epipleurae 

 being nearly as strongly sculptured as the back : under-side and legs shining black ; 

 tarsi reddish-pitchy ; antennae fuscous, and strongly thickened ; hind tibiae slightly 

 bent inwai'ds and asperous down their entire inner face. 



$ . Hind tibiae straight. Long. 6| to 1% lines. 



Queensland. 



Very near to C. connexus, Haag, but larger, the protliorax squarer, 

 the hind angles not prominent ; the antennae stouter, &e. 



Caediothoeax encephalus, Pascoe. 



This species is larger than connexus, Haag, the impressions on the 

 prothorax are constantly much stronger, the expanded sides are 

 broader, especially at the apex, the edges more uniformly thickened, 

 and the hind angles much larger ; the hind tibia? in the ^ are rela- 

 tively loucrer and more bent.
