AND OTHER INDIGENOUS ANTS. 213 
Female stouter. Head much larger: eyes small: ocelli very minute. Antenne less elongated than in 
the male, and 12-jointed; basal joint always elongated, second longer than the six following, and 
the club more robust (5).  Mandibles large and prominent, concavo-convex, forming serrated 
spoons, the teeth more numerous than in the males (6). Palpi similar to those of the neuter. 
Thorax rather short, broad in front and obtuse, postscutel producing two longish slender spines. 
Petiole and abdomen similar to the male, but furnished with a concealed sting. Wings as in 
the male. Legs stouter, the thighs and tibiæ being incrassated; tarsi similar, but shorter and 
stouter. 
Neuter resembles the female, but is much smaller; the Antenne are longer in proportion, and 12- 
jointed (7). Ocelli none. The trophi are very minute, excepting the Mandibles, which are com- 
paratively large, crossing, very dilated at the extremity, truncated obliquely and producing 5 or 6 
teeth (8). Labrum undiscovered. Maxille terminated by an oblique subovate very hairy lobe, 
and furnished with a slender drooping Palpus of 6 joints (9). Mentum chalice-shaped or obconic, 
with two remote Palpi of 4 joints (10). Thorax much narrower than the head, contracted at the 
middle; postscutel with 2 slender spines. Wings none. Sting concealed.

brinodis, Nyl. var. 
This is a most abundant insect, forming colonies, in meadows, on heaths and banks. 
The different species of Myrmice live principally under stones and clods, but they secrete 
themselves beneath the bark of trees and in moss. It should be observed that the pup 
are not enclosed in cocoons, in which they differ from the true Formice. The males fly in 
the evening, and the females are frequently found deprived of their wings, after pairing. 
2. M. zævinonis, Nyl. Mon. 927. 1. 
Taken in the middle of July at Folkestone by Mr. J. S. Baly, and towards the end of 
August I captured the male in Caen-wood. 
3. M. vacans, Fabr. Ent. Syst. ii. 358.37. M. ruginodis, Nyl. Mon. 929. 2. 
As this is undoubtedly the Fabrician species, I have restored the original name. It has 
been taken in the middle of July, at Sandown, in the Isle of Wight, by Mr. F. Smith.

This species resembles M. levinodis, but the males are much smaller, the antenne are 
much longer, and instead of the scape being only as long as the two basal joints of the 
flagellum, as in M. levinodis and M. rubra (fig. 1), it is equal in length to the eight om 
lowing joints (fig.12). The head is less convex, there is no channel down the forehead, 
and the clypeus is testaceous (fig. 11). There is a fovea on the hinder margin of the 
; i i fig. 13). The females, of which I have no winged
