males to the window, which, however, was closed—a 
failure of instinct. Very few workers major appeared. 
I killed thousands of the ants with carbolic acid. Not- 
withstanding this, and the fact that the window was an 
effectual barrier to swarming, the ants appeared again 
in a few days after, in the same place, with other males. 
(487). Hermitage Estate, Cumberland Valley, 1000 ft. ; 
open place. Dec. 2nd. At roots of plants on a rock. 
A large nest. 
(48 m). Windward coast of Robocea. Jan. 2nd. Door- 
yard, under stones. (The species is common on the 
windward side). 
N.B.—Mons. H. H. Smith a encore rapporté plusieurs 
? et g appartenant au genre Solenopsis, mais indéter- 
minables, parce que les 8 correspondantes manquent. 
Il se peut qu’ils appartiennent a des % déja décrites, et 
c’est un devoir de ne pas encombrer la synonymie de ce 
genre déja si difficile. Ces individus sont les numéros 
(10h) 2, (lla) 2 et 3, quatre especes de f pris au vol 
et sans numéros, enfin le No. 10a. la @ et l’ouvriére 
du No. 10a appartiennent a deux espéces différentes, 
mais l’ouvriére unique, fort rapprochée de la S. Castor 
n’est pas assez caractéristique, ni assez bien conservée 
pour qu’il soit permis de la décrire. 
(11). Perhaps referable to No. 9. 
(11a). Open place near sea-level; Cumberland Valley 
(leeward). Oct. 8th. Flying. Copulated (about 8 a.m.). 
7. Solenopsis succinea, Emery. (No. 88a). 3% 2 3. 
(33). Rare. The only formicarium seen was in the 
mountain forest, in rotten wood. Community large. 
The workers are rather sluggish.

The formicarium, or part of it, was uncovered by tearing 
off the bark of a rotten stump. Apparently there were 
other chambers deep in the half-decayed wood, but, 
having no axe, I could not get at them. The males and 
females were numerous, and I judge were about to leave 
the nest.
