188 REVISION OP THE AUSTRALIAN CURCULIONID^, 



base feebly insinuate, shoulders feebly produced on to prothorax; 

 densely and somewhat irregularly granulate, the granules — 

 especially at sides — with a small shining tip ; suture itself not 

 granulate at the base, very feebly raised; 2nd interstice slightly 

 raised and thickened at base; on each side of summit of posterior 

 declivity (which is almost vertical) a large, very distinct, rounded, 

 feebly granulate tubei'cle; sides with regular rows of very shallow 

 punctures, but striation distinct, feebler and more interrupted on 

 disc; apex rounded. Basal segment of abdomen not twice the 

 length of 2nd, apical feebly convex, longer than 2nd and almost 

 twice the length of intermediates. Coxce more or less noticeably 

 punctate; posterior femora in addition to the inner groove with a 

 feeble outer one. Length 11, rostrum 4; width 5; variation in 

 length 8-12 mm.

 Masters), Mt. Bellenden-Ker (Rev. T. Blackburn). 



The two large tubercles marking the summit of posterior 

 declivity of elytra are very prominent, and cause the species to 

 be one of the most distinct in the subfamily; owing to the declivity 

 being almost vertical they project slightly beyond the apex. 



POROPTEROIDES, n.g. 



Differs from Pseudoporopterus in having the pectoral canal 

 terminated at base of intermediate coxte, mesosternal receptacle 

 ver}' feebly raised, its apices produced forwards and touching 

 , anterior coxse, posterior coxje less widely separated than inter- 

 mediate (in that genus the separation is perceptibly wider) and 

 closer to apex of abdomen, 3rd tarsal joint moderately but dis- 

 tinctly bilobed, 4th rather slender, pubescent, eyes coarsely 

 granulate. 



The two genera are undoubtedly very close, but as the meso- 

 sternal receptacle is so little subject to variation between congeners, 

 and the difference between the two species is so strildng (in 

 dichotomus it might be likened to the third of a ring, and in 

 lennir to the thick end of a blacksmith's an^il) that taking into
