This paper is based on a collection formed at Calcutta by Rothney, and 
submitted to Mayr by (the late) F. Smith. Many species, both known 
and new, are mentioned, and the most important remarks on the former 
are as follows : — Camponotus vitiosus, Smith, — marginatus, Latr. (nec 
Oliv.), Formica mitis, Sm., is the small worker of his F. hacchus, and F. 
ventralis, Sm., is probably the ? of the same species ; C. inconspicuus, 
Mayr, = F. irritans, Sm. ; C. oblongus, Sm., ? described ; F. ruficeps, 
Sm., = C. gilviceps, Rog. ; C. fiavo-marginatm, Mayr, = F. pubescem, 
var. Brulle, = {C.) m^can5, Nyl. ; C. coxalis, Sm., worker minor described ; 
F. sedula, Sm., = his irritabilis ; Polyrrhachis is divided into six groups 
(spp. rdstellata, bihamata, armata, ammon, relucens, and abrupta) ; P. 
globularia, Mayr, = Icevissima, Sm. (female described) ; P. lamellidens, 
Sm., worker described ; P. sumatrensis, Sm., $ described ; Hypoclinea 
cordata, Sm., worker minor described ; Camponotus nutans and venustus 
and Ponera sulcata, Mayr, redescribed ; species of Ponera tabulated, and 
P. tesserinoda, Emery, worker described ; species of Lobopelta tabulated ; 
L. ocellifera, Sm., is probably a highly developed worker of mytabilis, 
Sm., {Ponera') ferox, Sm., appears to be a form of L. hitelli, Mayr j Typhl-
