348 REVISION OF THE AMYCTERIDES, U., 



Scrobes open behind, posterior portion not divided off. Eyes 

 small, subrotundate. Prothorax (5 x 6 mm.) rounded on sides, 

 postorbital sinuosity feeble; disc closely and finely granulate, 

 granules not contiguous; sides granulate. Elytra (15 x 8*5 mm.) 

 with apex moderately produced, mucronate, base feebly arcuate, 

 humeral angles marked by nodules, but not projecting ; disc 

 striate, stria? with shallow transverse punctures, interstices as a 

 whole not raised, sutural with a row of very fine obsolete granules 

 thickened at base, second with six larger (but still small) granules 

 distantly spaced; third raised and costate, becoming granulate on 

 declivity; fourth with four larger granules; fifth and sixth each 

 with a single row of small contiguous granules, on the sixth 

 almost subcostate. Fifth ventral segment with a rectangular 

 impression at extreme apex, subtended by a small nodule ante- 

 riorly. Dimensions : £.23 x 8*5 mm. 



i/a6. — "New Holland" (type in Macleay Museum). - New 

 South Wales : Mittagong (Australian Museum). 



Differs from all other species of the T. typicns-group, with the 

 exception of the following species, in having the third interstice 

 costate, thus combining the costate and granulate types of the 

 elytral sculpture. From T. rugicollis, the prothoracic granulation, 

 as well as the different elytral sculpture, will distinguish it.

9. Elongate-ovate, size large. Black, opaque, granules sub- 

 nitid; sparsely clothed with muddy scales. 



Head continuous with rostrum, forehead flattened between the 

 ends of the external rostral ridges. Rostrum deeply triangularly 

 excavate, external ridges convergent basally and extending to 

 vertex, less convergent on head ; internal long, convergent ; 

 median area triangularly depressed. Scrobes double, posterior 

 portion extending in front of eye. Eyes subrotundate. Prothorax 

 (4-5x5-5 mm.) widest in front of middle, apical sinuosity very 

 feeble; disc rugosely granulate, granules irregular, confluent; 

 sides more evenly granulate. Elytra (14 x 8 mm.) ovate, apex 

 moderately produced, base lightly emarginate, humeral angles 

 noduliform; disc with obsolete rows of depressions, sutural inter-
