Australian and Tasmanian CryptocepJialidcs. 405 



In two specimens the antennae are uniformly coloured, in 

 two others the apical half is more or less infuscate. 



Differs from Ocli. vcrmicidaris, Saund,, in being of differ- 

 ent shape, the scutellum very decidedly transverse and the 

 metasternum black ; from Cr. pa^cilodcDmcs, Chp.,it differs 

 in being wider, with narrower prothoracic margins, wider 

 subhumeral lobes and different punctures. 



In this and the three following species (and all of which 

 belong to a difficult section of the genus) the punctures, 

 owing to their stains, appear to be much bigger than they 

 really are. 



Cryptocephalus cariniventris, n. sp. 



(J. Pale testaceous, almost flavous ; junction of prothorax with 

 scutellum and elytra dark brown ; punctures of upper surface deeply 

 stained, those on prothorax and base of elytra darker (almost black) 

 than elsewhere ; flanks of metasternum infuscate. 



Head densely and coarsely punctate, punctures more or less con- 

 fluent. Antennaj longer than the body, second joint less than half 

 the length of third, third shorter than fifth, eleventh slightly longer 

 than tenth. Prothorax, sodellum and elytra much as in the pre- 

 ceding species, except that the prothorax is somewhat wider, with 

 slightly wider margins and denser punctures and the obliqiie impres- 

 sions more distinct. Apex of prodernum moderately wide and 

 strongly bilobed ; of mesosternum quadri sinuate. Abdomen with 

 the third segment just traceable across middle, the fourth appearing 

 as a triangular wedge on each side, the fifth large, of irregular shape, 

 with a large and not very shallow apical impression, bounded at 

 sides and apex by a cariniform ridge. 



Length b\ mm. 



Hah. Queensland : Brisbane {Geo. Compere). 



The apex of the prosternum from some directions appears 

 to be just as deeply excised as in Schizosternus, but this 

 appearance is due solely to a longitudinal impression 

 which terminates at the middle of the apex ; the abdomen 

 is also peculiar. 



The shape of the apex of the prosternum will at once 

 distinguish this from the preceding species ; in the male of 

 Cr. pmcilodcrmus, Chp., the third abdominal segment is not 

 traceable across the middle and the apical impression is 

 wider, shallower and with a much less elevated ridge 

 on each side.
