830 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



one spreading out on the 2nd interstice a little less than half-way 

 from the former to the apex, and a third close to the lateral margin at 

 ahiout half its length ; the punctures and stride are dark fuscous or 

 black. The puncturation of the head is rugulose but very tine 

 and close (much more so than in B. duplopunctatus), that of the 

 prothorax smooth and neither strong nor close (not unlike that of 

 Jj. >naju8culits). The elytral sculpture resembles that of £. nuijus- 

 cultis, except that the interstices are much more closely punctured ; 

 the whole organs too are considerably less drawn out towards the 

 apex than in that species, the apex itself being not emarginate but 

 produced in a short sharp spine. The underside of the male 

 closely resembles that of Ji. majitscuhis, except in having the whole 

 undersurface of the head black or nearly so, and the hind margin 

 of the metastemum less produced backward. The palpi are not 

 narrowly tipped with black as they are in B. majusculus, but are 

 rather strongly infuscate in the apical two-thirds of the last 

 joint. 



J possess a single example (also a male) from the same locality 

 as that described above, which differs from the type in being 

 slightly smallei', and of darker color, with a somewhat foveiform 

 impression at the middle of the clypeal suture, and also in being 

 somewhat more coarsely sculptured throughout, the elytral inter- 

 stices especially being less flat and more strongly punctured ; as 

 the specimen is not in very good condition and the differences are 

 all rather slight, I abstain from bestowing a new name upon it, 

 but I think it can hardly be regarded as a mere variety of 

 B. discolor. 



The unispinose apex of the elytra will distinguish B. discolor 

 from all the hitherto described Australian species of Berosus, 

 unless it be B. slicticus, Fairm., the elytra of which are stated to 

 be "obtusely acuminate behind;" but even if this expression 

 indicates a similarity in the apex of the elytra, the head of B. 

 sticticus is said to be " almost impunctate in front " while that of 

 B. discolor is punctured over its whole surface more closely than 

 in any other Berosus known to me.
