Manila, February 5, 1917, on Mallotus moluccanus; one male 
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 
same sex. This fact makes me suspicious that perhaps we have 
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.
