 and turned inward, ventral edge gradually produced into a short wide

 Hab. Buitenzorg, on palms. (Mnir, ]\IaY.) 

 I name this species after Mr. F. Leefman, to whose gnidance 

 I owe some verv pleasant collecting trips.

This species was described from a single specimen with dam- 

 aged antennae. I can now recognize that it shonld be placed 

 with the above species. All three differ from the description 

 of the generic type in the form of antennae, bnt I think there 

 is some mistake, as pectinata is described as having antennae 

 different from any Derbid yet known. I snbmitted specimens 

 of one of the above species to ]\Ir. Distant, who considers it 

 distinct from Devadanda, bnt I shall await the opportnnity to 

 examine the type before I erect a new genns.
