 from Manila, April 5, 1917, on Acalypha wilkesiana; one female

Tricentrus attenuatus Funkh. 



Add: Habitat. — Panay, Antique Province, Culasi {Mc- 

 Gregor) . 



Two males from Culasi, one taken in the forest on May 18, 

 1918, and one at a lower elevation on July 14, 1918. 



Tricentrus attenuatus was described from a male, and all of 

 the specimens which I have seen of this species have been of the

 here the opposite sex of some other species described from 

 female material only. It will be of interest to discover an 

 undoubted pair of this species.
