142 THE CARADIDAE OF TASIIAXIA, 



Hab. — Cradle Mountain (Carter and Lea). Several specimens. 

 Note. — A specimen in the Simson collection from the Blue Tier is 4.8 mm. iu 

 length, and has a similar prothorax, but the eljtra less strongly striate. 



PTEROcrRTUs (DRiiiosTOiiA) TA.siiANicu.s Castslnau. 



Brown; head, prothorax and margin of elytra reddish. Length, 3.2, breadth, 

 1.5 mm. 



Ilab. — Blue Tier (Simson, No. 3121). Two specimens. 



This is likely Drimostoma tasmanica Cast., but seems smaller than the type 

 form. Bates referred it to Oopterus. 



Three specimens were in the Simson Coll. under No. 3121, which are a little 

 larger and black in colour. Length, 3.6 — 4 mm. I believe they must go under 

 P. tasmanica. 



Pterocyrtus globosds, sp. nov. 



Apterous, subglobose; head large, lightlj' bi-impressed ; prothorax transverse, 

 wider across base (1.5 mm.) than apex (1.1 mm.); eljftra subglobose, subs'.,riate 

 on disc, smooth towards sides. Black; ehira with narrow lateral and wide apical 

 testaceous margin ; leg's and antennae reddish. 



Head wide, convex (1.2 mm. across eyes) ; frontal impressions parallel, short; 

 eyes convex, prominent. Prothorax convex, broader than long (1.3 ^ 1.7 wm.), 

 broadest just before middle, strongly angnistate to apex, gently obliquely narrow- 

 ed to base; basal angles rectangular; base tnmcate; two short basal impressions 

 on each side (inner foveiform, outer narrow) ; a short rather wide submargiual 

 carina near each basal angle; posterior marginal seta in lateral channel at basal 

 angle. Elj^ra subrotundate (3 X 2.6 mm.); three inner striae marked towards 

 base, tii'st entire, eighth strongly impressed; third interstice finely 3-punctate along 

 third stria, eighth shortly carinate at apes, ninth narrow, placed at bottom oi the 

 lateral channel. Length, 4.3 — 5, breadth 2.3 — 2.6 mm. 



Hah. — Cradle Mountain, TVaratah (Carter and Lea). A good series of speci- 

 mens. 



Differs from the black species in the Simson Coll., which T have referred 

 above to P. taamanicus Cast., by form shorter; prothorax shorter, more trans- 

 verse, more ampliate at widest part, wider across base, latei-al basal impressions 

 not so deep and more distinctly divided into two foveae, lateral basal carina 

 shorter, more distant from, and less parallel to the margin; elytra more ampliate, 

 inn(>r striae more distinct, sides and apex with a much more distinct ferruginous 

 margin. From P. striatulm SI., it differs almost by the same characters as from 

 P. tas7)ia)iicus, and has the elytra much less strongly striate. 



Pterocyrtus rubescens, sp. nov. 



Oval, convex; head with frontal channels not divergent posteriorly: jjixi- 

 thorax sub(|iiad7-ate, basal angles rectangular; elytra oval, convex, crenulate-striate 

 on <lisc, hunu^ral angles marked, scutellar striole wanting, basal border obsoiete 

 inwards from fifth interstice. Reddish, sometimes becoming brownish on disc of 

 elytra. 



Head convex (0.7 mm. across eyes); frontal channels wide, parallel, ex- 

 liniling backward In level with base of eyes, not out-turned at j)osterior extremity; 

 eyes not prominent, small, round, lightly convex; a narrow lateral sulcus passing 

 al)ove eye and extending behind eyes on each side of head. Prothorax broader
