punctured on the undersides. [Front tarsi wanting]. Dimen- 

 sions — 19 X 8-5 mm. 



//rt6. —Interior of New South Wales (Condobolin). 



A specimen (probably 9) ^^ under examination from the 

 Macleay Museum, through the courtesy of Mr. G. Masters. It 

 is readily distinguished from the other three species by (I) convex 

 and channelled head, (2) scarcely recurved prothoracic border, 

 and acute posterior angles, with canaliculate disc, (3) narrow but 

 very transverse scutellum, with triangular depression behind, 

 (4) nonrugose and foveate elytra, and (5) greater convexity in 

 both directions. Type in Macleay Museum. 



Four distinct species are before me, differentiated as follows : — 



1. B. reticulatus Pasc. — Prothorax with lateral border moder- 

 ately wide and strongly recurved; disc strongly punctured (evident 

 to the naked eye). Elytral intervals and undersurface strongly 

 punctate. 



2. B. ovensensis Cart. — Prothorax with anterior angles much 

 more emarginate, lateral border strongly thickened and less 

 recurved, Discal punctures very fine (not evident to the naked 

 eye). Elytral intervals and under surface much less strongly 

 punctate, first two segments of abdomen strigose. 



3. B. kosciuskoanus Cart. — Prothorax with anterior angles not 

 prominent, lateral border less thickened than in 2, and strongly 

 recurved only near apex. Posterior angle widely obtuse and not 

 deflected. Discal punctures as in B. ovensensis. Abdomen not 

 strigose, but punctures finer than in 1. 



4. B. Mastersii Cart. — Forehead and prothorax distinctly 

 canaliculate, acute posterior angles and scarcely recurved border 

 to prothorax. Disc smooth. Scutellum narrowly transverse and 

 accompanying elytral depression. Elytra foveate but not rugose. 

 The whole more convex, and apical declivity nearly vertical. 



Cardiothorax mimus, n.sp. 



Elongate-ovate, depressed, blackish-brown, opaque. 

 Head with frontal impression almost circular, basal joints of 

 antennse slender, succeeding joints stouter to the apex, each joint
