[Read October 2n(l, 1878.] 



(PL I.) 



Ccratorrhina Batesii. 



Oblongo-quaclrata, nigra velutina ; elytris utrinque 

 guttis septem albis. 



Long. 32 mill., lat. 15 mill. 



$ . Head quadrate, crown deeply hollowed, sides sinu- 

 ate ; clypens acutely produced at the lateral angles, and 

 Avith a small recurved bifurcated horn in the middle ; very 

 finely punctured and covered with small tufts of black hair. 



Thorax with the sides dark brown, covered with a fine 

 velvety pile, very closely punctured with minute depres- 

 sions ; sides strongly produced in the middle and abruptly 

 sinuated immediately behind the prominence. 



Elytra more densely clothed with velvety-purplish pile, 

 each elytron with two smooth carinas, the outer one sinking 

 into a large depression towards the base, the inner one 

 parallel with the suture ; seven ovate, more or less rounded 

 tawny-white spots on each elytron, placed one in the middle 

 towards the base, three in a line near the lateral margin, 

 and three also in a line and nearly parallel to the suture. 



Beneath, brownish-black, smooth, shining, mesosternal 

 process densely, and abdomen sparsely, pmictured. Head, 

 sternum, interior of abdominal channel and anal segment, 

 reddish-brown, edged with fine black pubescent fringe ; 

 legs black, smooth, sparsely punctured, coxai and ex- 

 tremities of tibife reddish-brown. 



Described from one specimen taken on IMount Cama- 

 roons by the Rev. Q. AV. Thomson, at an elevation of 

 about 3,000 feet. 



In Mus. F. J. Horniman. 



I can find no species bearing any affinity to this remark- 

 able Goliathide, with the solitary exception of C Sai/i, 

 Westw., with which it seems to be related chiefly througli 

 the conformation of the head and the carinated structiu'c 

 of the elytra, a character somewhat rare in this genus. 

 The quadrate form of the body, however, and the spotted 

 elytra, separate it very Avidely from C. Sai/i.
