168 NOTES ON AUSTRALIAN COLEOPTERA, 



overflowing on to the frontal area of the head; elytra with coarser 

 sculpture than typical form, seriate punctures larger, the inter- 

 stitial setae larger and more numerous, the humeral, basal, and 

 epipleural regions especially showing coarse, irregular punctures 

 with long, white hairs. Dimensions: llx5jmm. 



Hob. — Ben Lomond, 4,000 ft. alt. (A. Simson). 



Var. C. infirm Pasc. (Plate v., tig. 16). — More convex and nitid 

 than the typical species: sides of prothorax evenly rounded 

 without sinuation, the posterior angles widely obtuse; elytra 

 with coarser punctures and pilosity as in Var. P. 



Hab. — Melbourne, Vic. (Aust. Mus.); WestTamar (A. Simson), 

 Launceston (C. E. Cole). 



Var. P. foveatum Carter. (Plate v., fig.17). — Form very flat, 

 pronotum more rugose, elytral foveas larger. Dimensions: 

 10x4?, mm. 



Hab. — Mount Horror (Scottsdale District, Tasmania). 



Of the above varieties, A and C are the most distinct, but 

 intermediate forms between each of these and the typical form 

 occur, so that 1 have sometimes found it difficult to say whether 

 a specimen is actually abbreviatum or latum,, while Plate v., figs. 

 13 and 14, show the variations in "hind angle of thorax" in 

 typical forms. Hence arise my reasons for considering these as 

 variations. 



Seirotrana simsoni, n.sp. (Plate v., fig. In), 

 Oval, hlack-bronze, palpi, tarsi, and coxa 3 yellow, antennae (six 

 joints only present) castaneous. 



Head sparsely punctate, epistomal suture arcuate and deeply 

 impressed, antennae with joint 3 not as long as 4-5 combined, 

 4-6 suhconic, rest wanting. Prothorax 2|x3|mm,, lightly 

 emarginate at apex, subtruncate at base, anterior angles obtusely 

 rounded, sides well rounded, widest at middle, sinuate behind, 

 posterior angles rectangular; disc covered with close, fine, shallow 

 punctures, with a few larger setiferous punctures near sides and 

 apex, without medial line or distinct foliate margins, extreme 

 border fine and scarcely raised throughout. Scutellnm triangular
