[riate IX.] 



This is the forty-first paper of tliis series, and it is cliiefly 

 concerned in eivinijj a Plate illustratino: some interestino; 

 species. 



The measurements given by autliors in this and other 

 families, when only single specimens are avaihible, are some- 

 times misleading — &.g-, 1 have now an example of Platylister 

 procerus which measures 11^ mm., and another of Macro- 

 lister rohusticollis which measures 12^ mm., and a specimen 

 of Proholosternus africanus of 9 mm. The orioinal records 

 were 8|-9, 9, and 7 mm. respectively. The size given of a 

 species in the HisteridLe is only of an approximate value, but 

 it is essential that an accurate standard should be maintained 

 in using words such as ovalis, ohlongo-ovalis, subovalis, 

 hreviter-ovalis, and other terms employed by describers in 

 indicating the outline of a species.
