NOVEMBER. 1905. NORTH AMERICAN PARASITIC HYMENOPTERA. 
187 
two-thirds the length of the first, about twice as long as wide ; 
following joints subequal to second, except last which is nearly 
twice the length of the penultimate. Mesonotum with indica- 
tions of parapsidal furrows near its anterior margin, elsewhere 
shining and convex, impunctured. Scutellum as usual, with a 
deep groove at its base. Tegulae yellow. Metathorax brownish 
yellow, with a median carina which extends almost to the base 
of the petiole and a lateral carina on each side, the three con^ 
nected across the top of the posterior face by a transverse carina ; 
elsewhere coarsely reticulate. Abdomen as long as the head and 
thorax together, cauda one-third as long as the. abdomen. Petiole 
brown, about as wide as long, rugosely sculptured. Abdomen 
piceous brown lighter basally and yellow ; cauda yellow at base, 
black at tip. Legs brownish yellow, tips of tarsi blackish ; pos- 
terior tibial spurs weak. Wings brownish hyaline ; the stigma 
long, with parallel sides, pointed at tip, four times as long as wide. 
Stigmal vein short, marginal cell a little longer than the stigma, 
triangular. Discoidal veins very faintly indicated by fuscous 
streaks. 
One female, Morris Cove, Conn., May 20, 1904, received 
from H. L. Viereck. 
The present species differs from the more typical forms of 
Disof/mus in having only slight indications of mesonotal fur- 
rows. The venation agrees much more closely with this genus 
than with Proctotrypes however, and I am led to place it here.
