Subsequent to the publication of our first supplement on the ant 
larvae of the subfamily Cerapachyinae (1964), our first paper on 
Pseudomyrmecinae (1956) and several supplements on Myrmicinae 
(i960, 1972, 1973) we have received from other myrmecologists so 
much additional material that it has now become necessary to pub- 
lish a supplement. 
Genus Phyracaces Emery 
revision : The last sentence of our generic characterization 
(1964: 69) should read: Hypopharynx usually spinulose dorsally. 
Phyracaces elegans Wheeler (Fig. 2). Length (through spiracles) 
about 4.7 mm. Very similar to Ph. larvatus (1964: 69) except as 
follows. Body more slender. A pair of bosses on lateral surfaces of 
venter of AI-AVI. Spiracles small, AI largest, diameter decreasing 
posteriorly. Integument densely spinulose, spinules in short to long, 
subtransverse to arcuate rows. Body hairs less numerous and shorter 
(0.025-0.05 mm long). Head hairs shorter (0.009-0.019 mm long). 
Posterior surface of labrum with a ventrally directed medial boss 
bearing 6 sensilla, about 5 sensilla on each lateral surface. Mandi- 
bles with narrower base. No spinules seen on hypopharynx. 
young larva: Length (through spiracles) about 2.1 mm. Simi- 
lar to mature larva above except as follows. Neck curved, abdomen 
with straight ventral profile and C-shaped dorsal profile. Body hairs 
shorter (0.01-0.033 mm long). Integument spinulose, spinules mi- 
nute, isolated laterally and in short rows dorsally and ventrally. 
Antennae less distinct. Maxillae lacking spinules; galea a slightly 
raised pair of sensilla. No spinules seen on labium; opening of 
sericteries a short slit. 
very young larva: Length (through spiracles) about 1.5 mm. 
Entire body arcuate ventrally. Otherwise similar to young larva. 
Material studied: numerous larvae from New South Wales,
