Clypeus in front witli three notches in the middle, of wliich tlio 

 central one is the deeper, the lateral ones being but small, its sur- 

 face is even , and is densely and moderately coarsely punctured. 

 Thorax simple, nearly twice as long as broad, its surface closely and 

 rather coarsely punctured , the punctures becoming obsolete at the 

 middle part of the front niargin , it is bordered by a fine raargin 

 along the front and sides, and this extends also a little way along 

 the base from the bind angles, but is quite wanting on the greater 

 part of the base, Scutellum not visible. Elytra vory finely striated, 

 on the Striae are placed some very large, quite round punctures, tliese 

 being at a considerable distance from one another, the punctures are 

 smaller and the striae deeper at the deflexed extremity , the outer 

 row is abbreviatcd at the very deep and abrupt pleural sinuosity; the 

 interstices are quite impunctate. The pygidiura is broad and short, 

 and its lower half is entirely occupied by a peculiar deep ti-ansverse 

 Impression. Metasternum coarsely punctured at the sides, its middle 

 part quite impunctate, mesosternum rather broad, impunctate. 



My unique individual of this remarkable species I obtained from 

 Lafertes coUection where it was labelled „nov. gen. perforatus Reiche'^ 

 I am unable to detect any character to distinguish it as a genus 

 from the South African Coptorhina, except the quadridentato clypeus; 

 as I do not consider this character would of itsfelf justify the establish- 

 ment of a new genus, I leave the species in the genus Coplorldna; 

 possibly an examination of the trophi might reveal some distinctive 

 generic character. *
