Tliree males and a female of tliis striking species have 

 been collected and presented to the British J\luseum by- 

 Mr. H. J. Hillier. It differs from all other known species 

 by tlie deep coarsely-punctured grooves of the elytra. In 

 its armature it seems to agree with P. tectum, Blackb., 

 the very incomplete description of which omits all reference 

 to the elytra, which must therefore be supposed to be like 

 those of the species previously described. Blackburn's 

 insect is also considerably larger and has the thoracic cavity 

 filled with hair, which is quite absent in F. sulcatus. The 

 mentum, the form of which is the only real distinguishing 

 feature between Pseudoryctes and Cavonus, is swollen in 

 two of the specimens of P. sulcatus in the manner character- 

 istic of Pseudoryctes, and in the other two is collapsed and 

 nearly flat. The former condition must, of course, be regarded 

 as the normal one, but it is evident that this character is of 

 less importance than has been supposed.
