1912} The Pezomachini of Nerth America 139 
with a deep fovea on either side. Malar lines indistinct, cheeks rather 
swollen, closely and evenly punctured. Mandibles bifid with dark 
teeth. Palpi fuscous with apical joint piceous. 
Thoracic nodes sub-equal, rather coarsely punctulate; prothorax 
constricted anteriorly to form a neck, but not very markedly so. Meso- 
thorax rather shorter than the prothorax, from which it is separated by 
a well defined suture. Scutellum indicated by a small tubercle. ‘‘ Meta- 
thorax” strongly gibbous, with no indication of a carina but with a 
median shallow suture on anterior half. Legs rather more piceous 
than thorax. 
Abdominal petiole as long as the metathorax, only slightly expanded 
toward the apex, but with rather prominent spiracles, evenly shagreened 
and very sparsely pubescent. Remainder of abdomen oblong oval, 
2-214 times as wide as the thorax, dark fuscous, closely and evenly 
punctured, and with a short very sparse pubescence. Second segment 
with an indefinite piceous basal band. Third segment with a conspicuous 
broad black basal band. Remaining segments unbanded. Ovipositor 
somewhat shorter than the petiole, sheaths light at the base, black at 
the apex. 
Observations. Described from a single specimen hatched 
from a Drassid Egg Cocoon on May 7, 1911. Collected by 
A. B. Champlain, Lyme, Ct., April 30, 1911. bad 
This is evidently closely related to M. annulatum sp. nov. 
from which it can be readily distinguished by its darker color 
and sulcate thoracic nodes.
