clothed with scattering erect whitish hair. 
Paratypes show that the extent of the yellow markings is vari- 
able.

Stenogaster depressigaster, new species. 
Apparently allied to S. nigrifrons (Smith), but it can easily be 
distinguished from that species by the smooth scutellum and 
silvery (not golden) pubescence on the clypeus. 
Male—Length, 16 mm. Clypeus as long as broad; frons 
reticulato-punctuate ; vertex smooth; ocelli in an acute triangle, 
the diameter of the anterior one greater than the postocellar line; 
antennae stout, short, third joint nearly as long as the two fol- 
lowing; pronotum. practically smooth; notauli well defined an- 
teriorly ; scutellum and metanotum smooth; propodeum faintly 
transversely aciculate, and with a distinct median longitudinal 
furrow ; abdomen smooth, second segment with a short petiole, 
then gradually widening to apex, most of its dorsal surface. de- 
pressed, the depressed area with dense hair; apical sternite 
strongly concave, narrowing to a truncate apex. Black; base of 
antennae rufoferruginous; thorax somewhat brownish with the 
following yellow marks; anterior and posterior margin of prono- 
tum, scutellum, metanotum, four spots on propodeum and a spot 
below each pair of wings; legs brownish, the anterior femora and 
tibiae and the intermediate femora beneath yellow; wings sub- 
hyaline, venation dark brown. 
The paratype from Mt. Makiling has the dorsal pair of snots 
on the propodeum reduced in size and in addition has a spot at 
about the middle of the mesepisternum. 
Type-locality—Los Banos, Luzon, P.I. Described from two 
males collected July and August, 1917, by F. X. Williams, and 
one male from Mt. Makiling, Luzon, collected by C. F. Baker.
