PHILIPPINE PARASITES OF THE FAMILY 
TRIGONALIDAS 
By S. A. RoHWER 
Custodian of Hymenoptera, United States National Museum 
In 1874 Westwood described a species of Trigonalys from Min- 
danao. Since then no other species has been recorded from any 
of the Philippine Islands. Recently Prof. C. F. Baker has 
forwarded three specimens of trigonalids for identification. 
These were collected at Surigao, Mindanao, and represent two 
species. One of them is the species that Westwood described, 
and the other two represent a curious new genus of the sub- 
family Nomadininez, which has been named after Professor 
Baker and is described herewith. 
Genus BAKERONYMUS novum 
Genotype, Bakeronymus typicus sp. nov. ' 
Belongs to the subfamily Nomadinine Schulz and may be 
separated from the only other genus of the group by the number 
of antennal joints, shape of the head, etc. 
Male (female unknown).—Antenna 14-jointed, thickening 
apically, joints without tyloiden; head transverse, seen from in 
front more than two times as broad as high, smooth and shining; 
eyes very. large, occupying the entire side of head, their inner 
margins distinctly converging below; antennz inserted about 
one-fourth the distance from the lower margin of head, separated 
from each other by a distance twice as great as the distance 
from one antenna to inner eye margin; clypeus small, not 
defined dorsally, inserted between the antenne, so if its dorsal
