the base) than in any of those preceding. In some examples 

 we can perceive on the elytra a very minute pubescence. 



Length 54— 6| lines ; width of elytra 2^-34- lines. 



Hab. New Zealand. Six examples. 



Cilibe rugosa, n. sp. 



Near C. granulosa, but distinctly narrower ; the expanded 

 lateral margins of the elytra very narrow, not concave, except 

 slightly at the base ; the surface of the elytra distinctly punc- 

 tured, reticulately rugose, not granulose, or granulose-punctate, 

 and with three distinctly prominent costee on each ; humeral 

 angles not prominent, the sides not sinuous behind them ; and 

 the anterior tibise have the outer apical angle strongly den- 

 tiform. 



From the folio wmg ( G. tibialis, the only other species having 

 the outer apical angle of the anterior tibiae dentiform) it may 

 be known by its different form, somewhat squalid, opaque 

 surface, the elytra distinctly rugose, costate, and pubescent ; 

 the prothorax more deeply emarginate at apex, the front angles 

 more prominent, the hind angles not acutely produced, &c. 



Brown, slightly squalid ; head (except the epistoma) and 

 prothorax coarsely punctured, the interstices narrow, appearing 

 a little elevated, and a good deal broken up on the front of the 

 head and the base of the prothorax, allowing the punctures to 

 run confusedly together- Head trapezoidal in front; sides 

 of epistoma almost completely continuous with the anten- 

 nary orbits, the angles slightly rounded : prothorax arcuate- 

 emarginate in front, the angles a little produced, subacute, 

 directed forwards; sides regularly but moderately rounded, more 

 naiTOwed anteriorly than behind, a little sinuous in front of the 

 hind angles, these latter not acutely produced, slightly diver- 

 gent ; the three impressions by the base as ordinary, the two 

 outer strongly marked, and another rounded depression on the 

 middle, at each side of the median line : elytra rather strongly 

 narrowed behind, humeral angles not prominent ; sides slightly 

 rounded from the humeral angles, not at all sinuous behind 

 ihem ; the surface somewhat coarsely punctured, very distinctly 

 reticulate-rugose, and very thinly clotlied with a short, minute, 

 rigid, pale golden pubescence, on each elytron three very distinct 

 costse, with a much fainter one between them ; these send out 

 irregular, lateral, elevated branches, which cause the reticulate- 

 rugose appearance before mentioned, the interstices being some- 

 what squalid ; the punctuation, cost^e, &c. obsolete at the apex ; 

 lateral expanded margins very narrow, and concave only at 

 the base : underside brown, closely and somewhat coarsely 

 punctured, much more distinctly pubescent (especially on the
