Sub-genus Harpidium. 



(In this sub-genus I have had the invaluable assistance 

 of Mr. J. A. Wheldon, the British authority on the 

 group, who has most kindly examined and named all 

 the available specimens. Where specimens do not 

 exist the naming is exceedingly doubtful.)

to H. ex annul at um.) 

 Group Typicum Ren. 

 var. falcatum Schimp. 



Kelvedon (8) ! This specimen is almost midway
