tuies, placed in a transverse row, on each side of the vertex 

 about level with post-ocular prominences. Prothorax cordate, 

 very little broader than long (8 x 9 mm.), broadest just behind 

 anterior angles, gradually narrowed to near the base, then 

 constricted, the sides being straightened to meet the base ; lateral 

 margins broad, not reflexed, extending from anterior angle to 

 posterior constriction, then oksolete ; a row of setigerous punctures 

 along their length ; anterior margin longitudinally striolate ; 

 median line distinct ; disc transversely striolate ; basal part 

 rugulose. Elytra oval (17 x 10| mm.), rather convex, declivous 

 towards apex, striate ; striee fine near the suture, the interstices 

 not convex, those towards the sides strong, the interstices convex, 

 5th stria with three strong punctures on basal third. Posterior 

 tiochanters long, acute. 



Length 35, breadth 10|mm. (Mr. Bates's measurements are 

 26-30 mm. ; so my specimen seems an unusually lai-ge one.) 



A brief epitome of the facts relating to the distribution of the 

 Australian Broscini may prove of interest, though I can make no 

 attempt to draw any conclusions from these facts. 



The subfamily Broscini is represented in the Australian fauna 

 (excluding Nesv Zealand) by 80 species, divided among 9 genera 

 as follow : — 



Promecoderus (36 species) has its metropolis in the dividing ranges 

 of South-eastern Australia.* Twenty-two of the species are from 

 that part of Australia lying south of a line drawn from Brisbane 

 to Port Lincoln ; of these only P. concolor (from South-western 

 N. S. Wales, Victoria, and South Australia) and P. hlackburni 

 [from South Australia, Port Lincoln, and York Peninsula] are 

 found far removed from the mountain ranges. Three species, of 

 normal form, are from Tasmania and the islands in Bass Strait. 

 Four species, of normal form, from West Australia (of these P. 

 clivinoides, P. dyschirioiJes, and P. scauroides are very " close " 

 species). Four other species constitute a group (the P. bruymicornis 

 group*) peculiar to Tasmania ; two species {P. distinctus and/*.
