Australian and Tasmanian Cri/ptocephalides. 425 



triangularly pointed. Prothorax more than twice as wide as long ; 

 coarsely and very densely punctate ; margins narrow and entire. 

 Scutellnin moderately convex, coarsely punctate, base feebly notched 

 and not much wider than apex. Elytra elongate, subhumeral lobes 

 very small ; with very dense, round, moderately large, regularly dis- 

 tributed punctures ; each elytron with four very distinct and strongly 

 elevated costse, of which the outer (commencing just below the 

 shoulder) is the largest and becomes united to the sutural one close 

 to apex, the second from the suture commences closer to the base and 

 is larger than the third, but terminates before it. Pygidinm densely 

 and rather coarsely punctate. Under-surface with dense punctures, 

 many of those on abdomen transverse. Prosternum very decidedly 

 ridged along middle, apex rounded and entire. Abdomen with 

 larger segments (except the fifth which is smaller) than usual ; fovea 

 without lateral extensions. 

 Length 7i mm.

The dark sutural marking is very narrow at the base 

 and gradually becomes wider (although it is nowhere very 

 wide) towards apex, on the apex itself being slightly ex- 

 tended. In addition to the four distinct costse on each 

 elytra, there are traces of others both towards base and 

 apex. The intercoxal process of prosternum very dis- 

 tinctly produced and rounded at the hinder apex and 

 strongly ridged along middle, with the shape of the an- 

 tennae, decidedly distinguish this from the normal species 

 of Cryptoccplialus. 



DiANDICHUS FOVEIVENTRIS, n. sp. 



^. Oblong- obovate, moderately shining. Head, prothorax, scu- 

 tellum, antennae (the basal joints obscurely diluted with testaceoua), 

 tarsi, hind femora, part of middle femora and the apices of tibiae 

 (the hind more than the front), black ; rest of appendages and the 

 gular regions testaceous; elytra deep bluish-green. 



Upper-surface very densely and finely punctate throughout, pro- 

 thorax with moderately large and rather dense punctures, smaller on 

 disc than elsewhere ; elytra with rather dense punctures on basal 

 third, becoming smaller, sparser, and subseriate in arrangement 

 posteriorly. Head with or without a feeble median impression ; a 

 small fovea on each side of the clypeus. Antennas slightly longer 

 than the body, second joint more than half the length of third, 

 Prothorax about twice as wide as long, a rather shallow oblique 

 impression on each side. Scutellum very long and thin ; impunctate.
