AND OTHER INDIGENOUS ANTS. 213 



Female stouter. Head much larger: eyes small: ocelli very minute. Antennae 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 tibiae being incrassated; tarsi similar, but shorter and 

 stouter. 



Neuter resembles the female, but is much smaller; the Antennae are longer in proportion, and 12- 

 jointed (7). Ocelli none. The tropin 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. Maxillae 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 Myrmicce live principally under stones and clods, but they secrete 

 themselves beneath the bark of trees and in moss. It should be observed that the pupae 

 are not enclosed in cocoons, in which they differ from the true Formicce. The males fly in 

 the evening, and the females are frequently found deprived of their wings, after pairing. 



2. M. l^vinodis, 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. vagans, 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. 



4. M. longiscapus, Curt. 



This species resembles M. Icevinodis, but the males are much smaller, the antennae are 

 much longer, and instead of the scape being only as long as the two basal joints of the 

 flagellum, as in M. Icevinodis and M. rubra (fig. 1), it is equal in length to the eight fol- 

 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 

 second nodule ; the wings do not differ (fig. 13). The females, of which I have no winged 

 specimen, are very similar to those of M. Icevinodis, but they are darker, and the basal 

 nodule is shorter and stouter (fig. 14). The neuters are smaller and different in colour 

 from those of M. Icevinodis, being entirely ochreous, excepting the black eyes and a 

 brownish cloud on the back of the abdomen.— Male 2\ lines ; female 3 lines ; neuter If 

 to 2 lines long. 



I am aware that the length of the scape is supposed to vary in the males, but
