272 NOTES ON AUSTRALIAN COLEOPTKRA, 



condensed in three vittit on tlie prothorax and tlie former about 

 the base and sides of the elytra. This insecb may, however, be 

 at once distinguished from all its hitherto described congeners by 

 the number and arrangement of the spines on its elytra, which are 

 (besides the usual post-humeral spine) as follows : three on each 

 elytron placed in a series running obliquely hind ward from the 

 middle of the width (as seen from above) of the elytron a little in 

 front of the middle of the length nearly to a i)oint on the suture 

 just above the hind declivity, and one placed just outside the 

 middle spine of the oblique series. 



The sculpture of the front half of the elytra, moreover, is less 

 longitudinal and more transverse than in any other Catasarcus 

 known to me ; that of the hinder half consists of rows of large 

 punctures filled with ferruginous or whitish scales, while the 

 vestiture of the interstices is of a brownish colour.
