80 REVISION OF THE SUBFAMILY TENEBRIONIN ^^ 



Hah. — Warra, Queensland (Mrs. Hobler). 



A single {^%) specimen, kindly given to me by Mrs. Hobler, is 

 the largest described si3ecies, and differs from its nearest ally, P. 

 creber Blkb., in its black elytra, its dentate anterior angles of pro- 

 thorax, the absence of defined striae, of which P. creber is said to 

 have about 14. From P. striato-punctatus Westw., it differs still 

 more, not only in the form of the prothorax, but in its wider, more 

 parallel, and not at all cylindrical shape, with a quite different 

 elytral sculpture. Type in the Author's Coll. 



Platyphanes rugosulus, n.sp. 



Narrowly elliptic, very convex; head and pronotum iiitid cop- 

 pery-black, elytra dull coppery-brown, antennae and tarsi fuscous, 

 underside and legs black. 



Head distinctly but not very closely punctate, epistoma straight 

 in front, arcuately impressed behind, this impression joined by 

 two shallow longitudinal impressions extending backwards behind 

 the eyes, the latter rather widely separated ; antennae short and 

 slender, moderately enlarged at apex, joint 3 cylindric, not as long 

 as 4-5 combined, 4-7 obconic, 8-10 nearly round, 11 ovate. Pro- 

 thorax 3x5^ mm., widest at base, apex arcuate, anterior angles 

 obtuse, slightly depressed, scarcely advanced, sides arcuately 

 widening to base, posterior angles produced and acute, base 

 strongly bisinuate, lateral margins slightly raised, scarcely chan- 

 nelled within, disc finely punctate, with three small shallow foveae 

 at base. Scutellum triangular, punctate. Elytra of same width as 

 prothorax at base, and more than thrice as long, elliptic, very con- 

 vex, almost gibbous, with the highest point near middle, shoulders 

 obtuse, narrowly margined throughout, striate-punctate, the striae 

 indistinct, quite obliterated towards apex, the second stria scarcely 

 traceable throughout, the punctures in striae small and not deeply 

 impressed, intervals quite flat and finely transversely wrinkled; 

 epipleurae nearly smooth, abdomen very clearly and delicately 

 striolate-punctate ; prosternum earinate, its flanks coarsely and 

 sparsely punctate, meso- and metasternum finely and sparsely, 

 their epimera more coarsely punctate, mentum earinate in middle,
