1954 ] Wheeler and Wheeler — Badcerotini and Dacetini Ant Larvae 129 
bifid, with branches denticulate, on the dorsal and lateral 
surfaces. Cranium vaguely subhexagonal in anterior view, 
occipital border feebly impressed at the middle. Antennae 
minute, each with three sensilla, each bearing a moderately 
long spinule. Head hairs few, moderately long (0.039-0.12 
mm), flexible, with the distal half denticulate. Labrum 
small, twice as broad as long, bilobed ; anterior surface of 
each lobe with three minute hairs and/or sensilla; ventral 
border of each lobe with two or three sensilla and a few 
spinules; posterior surface of each lobe with three isolated 
and three contiguous sensilla; posterior surface spinulose, 
the spinules minute and in transverse rows. Mandibles 
heavily sclerotized, rather small, subtriangular in anterior 
view; apical tooth curved medially; two stout blunt teeth 
on the inner border. Maxillae large, apex paraboloidal; 
palp a skewed peg with one lateral (bearing a spinule) 
and four apical (two encapsulated and two bearing a spi- 
nule each) sensilla; galea a tall cone bearing two apical 
sensilla. Labium with the middle 2/3 raised into a broad 
ventral projection; anterior surface densely spinulose, the 
spinules in subtransverse rows; palp similar to maxillary 
palp but smaller; an isolated sensillum between each palp 
and the opening of the sericteries; the latter a transverse 
slit on the ventral surface. Hypopharynx with a few rather 
long rows of minute spinules. (Material studied: two 
dozen larvae from Burwood, Victoria, Australia, IX-12-51 ; 
collected by Dr. W. L. Brown and identified by him as E. 
sp. near qiLadrispinosa Forel.) 
Epoposiruma sp. 
(PL 7, fig. 20) 
Length about 3.6 mm. Quite similar to the Victorian 
species described above, except that the apical tooth of 
mandible is stout, straight and blunt. (Material studied: 
three dozen larvae from Aldgate, South Australia, VII-8- 
50; collected by Dr. W. L. Brown and identified by him as 
a new species near quadrispinosa Forel.) 
Brown, 19536; The larvae of E. spp. were observed to 
feed only on collembolans.
