and horizontal : the two together about 1 mm. wide, extreme 

 border a little raised and shining. Disc with seventeen rows, 

 on each elytron, of shallow, fine (but not minute), rather 

 distant and half-concealed punctures, the rows and punctures 

 confused near scutellum, and obliterated at apex, intervals 

 quite smooth and of uniform width ; the outside row of large 

 punctures more evident than usual (possibly by contrast). 

 Abdomen finely and closely punctured near base and centre, 

 (juite smooth at sides and on epipleurse ; prosternum with 

 strongly impressed, sinuate, longitudinal striae, becoming 

 fainter towards centre, tibial spines minute, femora smooth, 

 tibiae strongly punctured, and with a strong line of castan- 

 eous tomentum on inside. /Ji/t/msiniis, 15 x 9 mm.

A single specimen (^\ has been sent by Mr. C. H. J. 

 Clayton of the Sandstone Development Gold Mine. The re-

 species has been received from Tarcoola, through Mr. C. 

 French Its nearest ally is /'. conveochiscidiis Macl., to

 sternal striae should be a good character for identification, in 

 a section that has few enough marked characters for a literary 

 diagnosis. Type in the author's Coll.
