line which follows the eye margins ; frons and vertex shining and 
sparsely punctured; on the frons near the top of the eye is an 
elongate, shining tubercle ; intraocellar area and behind a narrow 
curved depressed line; postocellar line slightly longer than the 
ocellocular line; antennse submoniliform, the third joint slightly 
longer than the fourth ; anterior dorsal margin of the pronotum 
carinate and feebly dentate laterally ; scutum shining, with well- 
separated, distinct punctures; parapsidal furrows present ante- 
riorly; scutellum and metanotum punctured like the scutum; 
propodeum coarsely reticulate, the median impressed line of 
uniform width; mesopleura shining, almost impunctate, the 
sutures feebly foveolate; longer calcarium of the posterior tibia 
shorter than the hind basitarsus; petiole cylindrical, fully as 
long as hind trochanter and femur; abdomen shining; first 
recurrent joining first cubital well before the apex. Black; 
mandibles except apices, spot on tubercles, scape beneath, and 
four anterior tibise and tarsi yellow ; rather sparsely clothed with 
silvery hair; wings hyaline, iridescent; venation black.

from one male received from C. F. Baker.

Biodontus philippinensis sp. nov. 
Judging from the description this species resembles Psen rufi- 
ventris Cameron, but may be separated from that species by the 
different sculpture on the front, different propodeum, and 
shorter petiole. 
Female. — Length, 8 millimeters. Clypeus convex, the apical 
margin truncate, the surface irregularly punctured; face finely 
punctured; a strong carina, between the bases of antennse, 
extends ventrally until it unites with the complete transverse 
facial carina, and dorsally to the anterior ocellus (not so prom- 
inent above the antennse) ; frons, vertex, and posterior orbits 
smooth, shining ; between ocelli and eye an elongate raised area : 
postocellar line slightly shorter than the ocellocular line ; antennse 
slightly thickening apically, scape curved, the third joint slightly 
longer than the fourth; pronotum carinate anteriorly, anterior 
lateral angles sharp; mesoscutum with sparse, small punctures.; 
parapsidal furrows weak, extending about half the length of the 
scutum; mesepisternum smooth, shining; scutellum sculptured 
like the scutum ; inclosed area on propodeum broadly triangular, 
sharply defined posteriorly by a carina and with longitudinal 
rugse; sides and posterior surface reticulate, posterior surface
