not very convex, not flattened near the base, but sharply- 

 declivous to the peduncle ; sides parallel, not perceptibly 

 narrowed at the shoulders ; five distinct sti-ite on each side 

 of the suture, the others lighter, or indistinct ; the striae reaching 

 the apex ; the interstices equal. Three last ventral segments 

 foveafce on each side, a transverse impression extending inwards 

 from the foveas (the transverse impression on the last segment 

 connecting the fovese in the ^, but not in the j). Four first 

 joints of the anterior tarsi dilatate and spongiose below. 



Q. — More robust; prothorax broader than long (4 x 4^ mm.) 

 elytra more convex (8 x 4|), broader and more rounded on the 

 sides. 



(J. — Length 13, breadth 4| mm. ; §. — Length 13J, breadth 

 4 1 mm. 



^a5.— Monaro District, N.S.W. 



A very distinct species, and well characterised by the elongate 

 prothorax of the ^ very little rounded on the sides, gently and 

 evenly narrowed behind; the median line is lighter, and the 

 basal angles of the prothorax are more obtuse than in any other 

 Australian species I have seen. After examination of the type 

 specimens in Sir William Macleay's collection I cannot see any 

 specific difference between his P. inornatus and P. puncticoUis. 

 A specimen (^) in my collection from Mount Kosciusko (for which 

 I am indebted to Mr. W. W. Froggatt) differs in its broader and 

 more convex form, in having the prothorax declivous behind, with 

 the basal angles hardly so obtuse ; it is possibly a new species. 



Promecoderus dorsalis. 



P. dorsalis, Macl. I.e. p. 333. 



Shining black ; the tarsi, antennae, and jialpi piceous ; first joint 

 of antennte hardly lighter-coloured than the others. Head 

 smooth ; vertex with a very wide and shallow transverse im- 

 pression ; the frontal impressions well marked, shallow, extending 

 behind the clypeal suture, this distinct ; the post-ocular 

 prominences large, about equal in length to the eyes. Prothorax
