and Reasia Gray, have been referred to the Lysiopetalide. As no 
species have been published under them and practically no descrip- 
tions are given, they may be looked upon as nomina nuda, and not in- 
cluded in the synonymy of any of the genera. The following, then, 
are the genera of Lysiopetalide which have not been properly disposed 
of, and may for the present be assumed to be valid: 
Genus Callipus Leach (1826) ; type rissonius Leach; locality, Nice. 
Syn. (Subg.) Lysiopetalum Verheeff; type illyricum Latzel. 
Genus Lysiopetalum Brandt (1840); type fatidissimum (Savi); 
locality, Italy. 
Syn. (Subg.) Sylvestria Verhceff (1895) ; type fetidissimum (Savi). 
Genus Spirostrephon Brandt (1840) ; type dactarium (Say); locality, 
North America. 
Syn. Platops Newport (1844) ; type rugulosa (Gray)=Tlactarium (Say). 
Genus Eurygyrus C. L. Koch (1847) ; type rufolinatus C. L. Koch: 
locality, Constantinople. 
Genus Megastrephon nov.; type xanthinum (Newport); locality, 
Asia Minor.—O. F. Coox. 
Habits of Ants.—In an interesting paper on the ants of India® 
Mr. G. A. J. Rothney reports that the nest of a colony of Myrmicaria 
fodiens Jerdon, under a banyan tree in the park at Barrackpore which 
had been constantly under the author’s notice between 1872 and 1886 
was still flourishing in January, 1894, showing a continuous residence 
in one spot of twenty-two years. In Madras he found Monomorium 
salomonis Lin. used in protecting bales of paper from white ants. The 
paper merchant scattered sugar around the sides of the bales every day 
to ensure the attendance of these red ants. 
Concerning Pheidole rhombinoda Mayr. Mr. Rothney says: “I 
found some nests in Barrackpore Park, covered over in a perfect circle 
(taking the centre from the entrance, the circumference would equal 
about 10 to 12 inches), with the leaflets of some species of mimosa, but 
no leaflets were found in the nest itself on digging it up, and the even 
and umbrella-like appearance of the arrangements seems to suggest a 
protection against heat or rain, as the objects the ants have in view. 
“Tn Madura, I came across a number of nests of a very curious and, 
to me, novel form. 
“ The entrances were surrounded by little mounds arranged in a circle, 
composed of the dead bodies, or parts of bodies, of Camponotus com- 
ê Trans. Ent. Soc. London, 1895, Part II, pp. 195-211.
