150 THE r.VRAUIDAE OF TASMANIA, 



Allied to T. nitens Putz., which it closely resembles, but laraor: inothovax 

 more cordate; elytra more convex, wider, more strongly rounded on sides, )tiore 

 anipliate on each side of peduncle in a more evenly rounded curve. The wider, 

 more convex, and more rotundate elytra are Ihe most conspicuous differences. Tt 

 differs from 7. Utsmaniae Bhickb. by size larger; prothorax less njunded on sides, 

 border promincht at l)asal angles, etc.

 quadrate, base sliortly lobate, posterior angles obtuse; elytra witli tliree inner 

 striae marked, othei-s (including eighth) obsolete, recurved apical striole distinct, 

 third interstice 3-pnnetate (two anterior punctures beside third stria, third 

 puncture on apical declivity beside second stria), an elongate striole at base of 

 first interstice, liasal border reaching scutelhun. Piceous; elytra witli latei'al 

 channel, infiexe<l margin, and apex ferruginous; femora hirid-testacemis; til)iae

Head large (0.8 across eyes); frontal sulci deep, curved, strongly divergent 

 posteriorly; median frontal space convex, not as wide as lateral spaces, these 

 convex; sui)ra-(>rl)ital ])nnctures near eye, anterior set in a foveifonn puncture; 

 eyes hemisiiherical, large, prominent; postocular part of orbits laminate, strongly 

 and aliruptly raised from head. Prothorax liroiuler than long (0.8 X 1 nmi. ), a 

 little wider across basal angles than apex; anterior angles wide, rounded; apex 

 truncate; sides lightly rounded; basal curve between posterior angles wide, bisinu- 

 ate, curving forward from sinuosity to posterior angle on each side; basal lolw

 angles; anterioi- transverse imjjression faint: b;\se (le<-livous on each side towards 

 margin; posterior marginal seta on edge of border at posterior angle. Elytrn 

 subde|>ressed (2.5 X 1.7 mm.), laevigate outside discal foveae, wide at oase; 

 humeral angles rounded; sides subparallel (hardly rounded); two inner slriae 

 well marked, second not reaching apex, third faint. Lo'ng'th, 4. breadtli. 1.7 mm. 



TTrih. — Cleveland ( Simson, No. 3504). T^'nique. Orampian Mountains, ^'ic■-

 larger size; clarker ciilcnir; jirotliorax with jiosterior angles far less marked; elytra 

 with more than nne stria cm each side of suture.
