more rounded than in atratulus. Seen from behind the 
broad longitudinal impression on the posterior face of the 
epinotum is broadly rounded above (narrower and rather 
pointed above in atratulus) . Seen in profile the node of the 
petiole has a definite, short posterior face, a rounded and 
rather narrow summit and a long steeply sloping anterior 
face. Although both posterior anterior peduncles are short 
both are distinctly visible in profile and sharply set off from 
the node (in atratulus the node of the petiole is much bulkier 
with the dorsum broad and obtusely angular. The anterior 
and posterior peduncles are so short as to be virtually in- 
visible when seen in profile). Postpetiole seen from above 
thinner from front to back than in atratulus with the an- 
terior edge much less convex. The dorsum bears a shallow, 
median longitudinal sulcus (entire in atratulus). Abdomen 
with a deep median sulcus as in atratulus. 
Sculpture very finely and evenly punctato-rugose except 
the very deeply notched clypeal border, the mandibles and 
the appendages which are shining. The sculpture is uni- 
formly heavier than in atratulus, particularly on the pos- 
terior abdominal segments where it renders the surface 
definitely opaque (feebly shining in atratulus) . 
Color: head and thorax blackish brown, gaster a some- 
what clearer brown, appendages dirty yellow. Wings hya- 
line, covered with numerous small hairs, the veins and stig- 
ma pale yellow. 
Type in my collection. 
It is much to be regretted that this interesting insect is 
known only from a single specimen. Following Mr. Fried- 
land’s discovery I returned with him to the type locality, a 
small meadow at the side of U. S. Highway No. 9 about three 
miles north of Englewood, N. J. In this place there are 
many nests of Tetramorium csespitum constructed in coarse, 
gravelly soil along the sides of a fill over which the highway 
runs. Although we examined a number of the nests and 
although, during the following spring, the site was revisited 
for more extensive observation, no additional specimens
