capping the ventral end of the gula; anterior surface with a few 
minute spinules in regular transverse rows (concealed behind la- 
brum) ; palp a cluster of three sensilla. Opening of sericteries a 
long transverse slit. (Material studied: several larvae from New 
South Wales.) 
Wheeler, 1918: “Long and slender, cylindrical and not enlarged 
at the posterior end, with eleven distinct postcephalic segments, all 
uniformly clothed with short, erect, two-branched hairs. Head 
small, as broad as long, with vestigial antennae and long falcate 
mandibles, which have finely serrate internal borders. There are 
few hairs on the head and these are simple, with the exception of a 
pair near the occipital border, which are two-branched like those on 
the body. The color of the larva is dull white” (p. 228). Fig. 2 
shows a larva in side view, a head hair, the head in anterior view 
and a mandible (p. 227). 
Wheeler, G. C., 1938; no leg vestiges (p. 140) ; no vestigial gon- 
opods (p. 142). 
Genus Cerapachys F. Smith 
Leg vestiges small paraboloidal papillae. Body hairs simple. 
Head (including mouth parts) subpyriform in anterior view; cran- 
ium transversely subelliptical ; occipital border slightly curved. Head 
hairs short. Labrum small, not covering the bases and tips of the 
mandibles ; breadth one and one-half times the length ; constricted 
near the base; free border strongly curved; numerous sensilla on 
the free border and posterior surface; posterior surface spinulose 
near periphery. Maxillae with the apical half spinulose ; palp a low 
elevation together with a contiguous papilla. Labium with spinules 
on the middle of the anterior surface. 
Cerapachys ( Syscia ) cryta Mann. — Fig. 2 a-d. Anterior portion 
of prothorax constricted abruptly to form a short wedge-shaped 
neck. Vestigial legs a pair of small paraboloidal papillae on the 
ventral surface near the middle of the posterior border of each 
thoracic somite. Spiracles small. Body hairs few, very long (0.4-0. 6 
mm.), simple, flexuous and extremely slender; longest and most 
abundant near posterior end; also a very few minute (0.013 mm.) 
stiff hairs. Head (with mouth parts) subpyriform in anterior view; 
small ; mouth parts large and prominent ; cranium transversely sub- 
elliptical. Head hairs few and scattered; simple, slightly curved, 
short (0.036 mm.). Antennae moderately large; each with three
