The present species may be distinguished from mangifera; by the smaller 

 number of antennal joints ; by the exceptionally short tarsus, and by the absence 

 of the well-defined dermal pores that form such a conspicuous feature in 

 mangi/erts. 



Lee. acuminatum may be sufficiently separated from capparidis by the 

 deeply-divided marginal hairs, those of the latter species being simple.
