478 Mr. F. Bates on New Genera 



Cilibe elongata, Breme, and C. phosphugoides, White. 



Examples of G. elongata obtained from the collections of 

 Reiche and Doue (presumably authentic exponents of the 

 species) do not differ from C. phosphugoides except in the 

 form of the prothorax, which in the former has the sides more 

 obliquely narrowed anteriorly, and the elytra, which are more 

 acuminate behind. Experience has shown us that these 

 differences possess no true specific value in this genus : 

 C phosphugoides must consequently be sunk under C. 

 elongata. 



This species is much smaller than any of those preceding ; 

 the form is more or less elongate-oval ; prothorax shining 

 black ; the expanded lateral margins paler ; the elytra are of 

 a more or less deep purplish or chocolate-brown. Head convex 

 between the eyes, trapezoidal in front, with the borders 

 usually dark ferruginous, more or less strongly, closely, and 

 sometimes rugosely punctured ; epistoma convex, more or less 

 distinctly arcuate-em arginate in front, the sutural impression 

 more or less distinct : the form and punctuation of the pro- 

 thorax is variable ; it is always of a shining black, convex, a 

 depression on the middle near the base, another smaller at each 

 side at the basal margin ; usually very finely and not closely 

 punctured on the disk, the punctures more crowded at the 

 sides and finely rugulose, more or less distinctly granulous on 

 the intervals ; lateral margins moderately expanded and con- 

 cave, the edges finely and uniformly thickened ; apex deeply 

 emarginate, front angles more or less acute, and usually a 

 little convergent, sometimes directed forwards ; base closely 

 applied to the base of the elytra, bisinuate, hind angles promi- 

 nent, reposing on the shoulders of the elytra, acute, usually a 

 little outwardly directed ; ordinarily the sides are a little 

 sinuously contracted posteriorly, but sometimes they are sub- 

 parallel (in this latter case the base is as wide as the base of 

 the elytra) ; anteriorly they are always more strongly con- 

 tracted, sometimes very gradually (obliquely) from behind the 

 middle, at others more abruptly (curvecQy) from the middle or 

 even before the middle ; scutellum transversely triangular, 

 punctured : elytra oval, more or less acuminate behind, convex, 

 subopaque, of a dark purplish brown ; frequently the base 

 (narrowly), the suture, the expanded margins, and the scutel- 

 lum are of a reddish tinge ; base sinuous, and generally a little 

 wider than base of prothorax ; expanded lateral margins 

 narrow, concave, not distinctly reaching the apex ; disk with 

 numerous more or less distinct longitudinal costse, irregularly 

 punctured, finely rugose (most strongly at the sides), and
