62 HARVESTING ANTS. 



matter, and has never been seen by me carrying seeds. Nest 

 in the ground. (Mentone and Cannes.) 



(4) F. (Camponotus) marginata, Latr. — Large (i to 5^ 

 lines), black. Has no perceptible smell even when crushed. 

 Lives principally on sweet secretions, and does not bring in 

 seeds to its nest, which is made in the ground. I have seen 

 this ant at Cannes ascending the cork oaks in search of certain 

 cocci which resemble black and shining berries rather larger 

 than a pea, and which exude sweet secretions. (Mentone 

 and Cannes.) 



(5) Formica cursor, Fonscol. — A rather large but slender 

 ant (8 to 4 lines long), nearly black, with a faint bronzy hue, 

 legs very long. Smell not noted. Runs very swiftly, and is 

 hard to catch ; feeds on sweet secretions, and does not carry 

 seeds. Nest in ground. (Cannes.) 



(6) F. (species undetermined). — A large ant (5 to 6^ lines), 

 black brown with yellow thorax and legs. In shape resembles 

 F. onarginata. Strong smell of formic acid. Habits not 

 observed. Nest found under a stone in a pine wood. (Cannes.) 



(7) F. (species undetermined). — A rather large ant (3 to 

 4^ lines), resembling F.fusca, but having the thorax yellow. 

 Strong smell of formic acid. Feeds on sweet secretions, and 

 does not carry seeds. Nest in ground. (Cannes.) 



(8) Forraicob {Tapinomo) erratlca, Latr. — Rather small 

 (2 lines), nearly black. Has a strong and most disagreeable 

 smell, something like rancid oil, which is emitted if the nest 

 is disturbed or the insect crushed. Lives upon sweet secre- 

 tions and animal matter, but rarely if ever carries seeds, and 

 paj s no attention to them if placed in its path- It nests in 

 the ground, and forms superficial covered ways, roofed in with 

 a thin crust of earth and vegetable fibres cemented together. 

 (Mentone, Cannes.) 



Tribe Myrmicinece. Petiole two jointed, furnished with 

 two nodes (protuberances). 



(9) Crematogaster {Myrmica) scutellaris, Oliv. — Of 

 medium size (3| to 4 lines), nearly black, with yellowish red 

 head. Disagreeable smell like rancid oil when crushed. 

 Erects the abdomen when excited, and runs about with it 

 turned up at right angles to the body. Lives on sweet secre-
