This paper is a further contribution in a series which, 
when complete, will cover the Indo-Australian portion of 
the world fauna of the dacetine ant genus Strumigenys Fr. 
Smith. Previous parts, the first two of which include ex- 
planations of the abbreviations used for citing measure- 
ments and indices, are in Psyche 60: 85-89 (1953), 60: 
160-166 (1954) and 61: 68-73 (1954). 
The last reference just cited contains the description of 
S. chapmani Brown, from the Philippines, a species that is 
very difficult to assign to any species group. There are also 
known from the same islands a member of the szalayi group 
( australis or near) ; an undescribed species, apparently 
nearest S. honing sb erg eri Forel; a member of the “Labi- 
dogenys” complex, probably new, and four species of the 
godeffroyi group, including S. godeffroyi Mayr and the 
three forms described here for the first time. This makes a 
total of eight known Strumigenys , which is undoubtedly 
only a fraction of the number actually to be found in the 
Philippines. 
So far as can be determined from the present samples, the 
Philippine Strumigenys fauna is Indo-Malayan in affinities, 
with also an element ( australis ) of probable Papuasian
