424 PROF. F. J. BELL ON THE TEMNOPLEURIDjE. [JunC 1, 



1. Temnopleurus toreumaticus. 



This species is so well known that there is no need to delay over it. 

 2. Temnopleurus hardwickii. 



With regard to the height, it would seem that it is not so much 

 that changes occur in it during growth, as that there are considerable 

 variations in it, with a tendency to a high form (63 per cent.) and a 

 low form (47"7 per cent.), 



3. Temnopleurus reynaudi. 



As I have already pointed out, I believe that in the latest Re- 

 vision two distinct species have been united under this head. 

 Mr. Percy Sladen has given expression to a doubt on the subject' ; and 

 he informs me that the type of Dr. Gray's T. granulosus struck him 

 as being " a good species " when, some time ago, he had the oppor- 

 tunity of examining it. T. reevesii of Gray does, however, seem to 

 be synonymous with the T. reynaudi of Agassiz. 



When the types of the two species are compared, we find that in 

 T. granulosus the abactinal area is of moderate size and there is no 

 specially large plate in the anal area ; the connecting ridge of the 

 auricles - is lower than in T. reevesii ; the miliary tubercles are very 

 numerously developed and surround the primary tubercles ; sutural 

 furrows, quite distinct from the pits of T. reevesii, occupy the middle 



1 J. L. S. xiv. p. 437. 



^ I feel inclined to attach a little more importance to this character then does 

 Prof. Agassiz, who says of it that it is high, when be is defining the genus, and 

 very low, when defining T. hardwickii (p. 461).
