new species of the Coleopterous genus Callirrhipis. 393 



punctato ; thorace postice longitudine vix latiori, convexo, 

 antice parum angustiori, crebre sat fortiter punctato, ante 

 medium linea mediana impresso ; elytris crebre sat fortiter 

 punctatis, costis sat elevatis. $ . 

 Long. 7 lin. ; lat. 2^ lin. 



Rather a convex cylindrical species, with the thorax not 

 much enlarged behind. Head rather convex, with a short 

 impressed line on the vertex and a transverse deep fovea 

 just before the base of the antennae; the punctures are 

 rather strong, very close but not crowded. Thorax gradu- 

 ally and not much narrowed in front (not suddenly en- 

 larged at the posterior angles), convex, very thickly and 

 rather strongly punctured : there is a short impressed line 

 in front, and a shallow round impression near the scutel- 

 lum, the space within posterior angle shallowly excavated. 

 Elytra veiy distinctly and rather closely punctured, the 

 punctures rather unequal in size ; each elytron with four 

 moderately distinct costce, the lateral one not extenduig to 

 the shoulder.

Testaceo-rufa, sub-opaca, tenue pubescens ; antennis, 

 thoracis macula discoidali, tibiis tarsisque nigris ; capite 

 crebre rugoso-punctato ; thorace antice parum angustato, 

 crebre rugoso-pimctato, disco utrinque foveola notato ; 

 elytris crebre fortiter punctatis, costis nitidis elevatis. $ . 



Long. 6 lin. ; lat. 1§ lin. 



Head and thorax densely, rather finely and rugosely 

 punctured, the former with a small black spot on the ver- 

 tex, the thorax with a black spot in the middle. Thorax 

 gradually and not very mvich narrowed in front, the fi'ont 

 margin arched ; the discoidal foveas are not very distinct. 

 Elytra very thickly and strongly punctured ; each elytron 

 with four distinct shining costaj, the tliird extending a 

 little beyond the middle, the fourth obliterated near the 

 shoulder.

I have determined the above to be a variety of C. La- 

 portei, Hope (T. E. S. iv. p. 181); but besides the dif- 

 ferent coloration of the elytra it has the basal joint of the 

 antenna3 black, which inclines me to think that it may 

 prove to be a distinct species.
