had charge. The name metathoracica is unfortunately chosen, 
for the color character on which it is based is not conspicuous 
and is an apparently rather rare variation, the thorax being 
usually entirely ferruginous. 
What I take to be the male of this species is represented in 
the National Museum collection by four specimens, all taken at 
Manila, Philippine Islands, by Rev. Robert Brown. These 
are the Acanthohemiteles benjamini Ashmead manuscript, of 
Brown’s list of Philippine Hymenoptera. There are also nine 
additional females taken at the same place by the same collector. 
Aside from the very different abdomen the male differs from 
the female principally in having the thorax black or largely 
black. In one of the four specimens examined the propodeum 
is piceorufous. In the female the third and fourth tergites 
are subangulate laterally at apex. 
Syrites arealis Sp. Nov. 
Differs from S. metathoracica (Ashmead) and apparently 
from all of the other described species in the structure of the 
second and third tergites, the usual transverse furrow meeting 
laterally the extremities of a basal reversely curved furrow, 
the two setting off a transverse median area. 
Female.—Length, 5 millimeters; antenne, 4. Slenderer than 
S. metathoracica (Ashmead). Head distinctly broader than 
thorax; temples strongly convex; vertex with strie radiating in 
all directions from ocelli, a deep short groove between the lat- 
eral ocelli; frons transversely, arcuately striate; face finely, 
confluently punctate, elevated medially; clypeus punctate, me- 
dially irregularly striate; face, clypeus, and cheeks clothed with 
moderately dense white pubescence; temples and cheeks irreg- 
ularly vertically striate, posterior orbits punctate; malar space 
nearly as long as basal width of mandible. Thorax subopaque, 
pronotum with the lateral furrow deep, subpolished, the dorsal 
portion somewhat swollen and obliquely striate; mesoscutum 
obscurely transversely striate, each lobe with a median opaque 
streak; scutellar fovea deep and foveolate but not distinctly . 
carinately margined before and behind; scutellum reticulate 
punctate, margined laterally to middle; mesopleurum, metapleu- 
rum, and propodeum with long white pubescence, the pleura 
confluently, almost rugosely punctate; propodeum irregularly 
rugulose, the basal areas not defined, areola hexagonal, removed 
from base by its own length, lateral carina distinct only beyond 
apical carina, petiolar area nearly vertical, shorter than dorsal
