670 REVISION OF THE AUSTRALIAN CL'RCULIONID.E, 



slightly shorter than 2nd and slightly longer than 3rd, 5th-7th 

 subequal in length. Frotkorax with a strongly elevated median 

 carina in front, stoutest in middle, and from there feebly con- 

 tinued to base; each side of it in front not granulate, but else- 

 where with large granules, each of which is supplied with a sooty 

 seta. ^cutellu)nxo\xxv^. ^/^^ra about once and one-half the width 

 of prothorax, shoulders produced laterally and angular ; sides 

 decreasing to apex, apex widely rounded; suture strongly raised 

 from near base to about one-third from apex, the ridge granulate 

 and abrupt at both its base and apex, a distinct and moderatelj'' 

 large subconical tubercle^ on third interstice near base; seriate- 

 punctate, the punctures large but rather shallowf; interstices 

 narrow, those near the suture feebly granulate, the 5th and 6th 

 on the disc and shining from near base, the 7th-llth on the sides 

 and highly polished, the 7th and 8th uniting to form the humeral 

 projection, the 9th and 10th curved upwards at base; posterior 

 declivity feebly striate and very feebly punctate. Mesosternal 

 receptacle U-shaped, walls thin, open except at extreme base.| 

 Legs long; posterior femora just extending to apex of elytra. 

 Length 20, rostrum 8; width 10; depth 9^ mm.

In this species the pectoral canal terminates distinctly beyond 

 the middle of the intermediate cox^e ; in the two following it 

 terminates before them. 



Mr. Waterhouse remarks : — " I have an insect which agrees 

 with Schonherr's description of Protojjahis Stephensii so perfectly 

 in all respects, excepting that the rostrum is not crenulated 

 beneath, and the anterior legs are but a trifle longer than the 

 others, that I strongly suspect their differences merely indicate a 

 distinction of sex."§ I do not think it probable that Mr. AVater- 



* Varying in size on different individuals. 



+ In some specimens the punctures of the lateral stri® are separated by 

 ridges, but this does not appear to be invariably the case. 



+ As at its base it slightly overhangs the pectoral canal it cannot be called 

 open, although on a first glance it appears to be so. 

 § Mr. Waterhouse possibly had a specimen of cristcUus under examination.
