[March-June 
days, total 36-45 days. Life cycle in mature colonies: egg 8-12 
days, first instar 2-7 days, second instar 3-7 days, third instar 10-19 
days, semipupa 5 days, pupa 12-18 days, total 43-63 days. 
Genus Triglyphothrxx Forel 
Triglyphothrix striatidens Emery 
immature larva. Length (through spiracles) about 2.2 mm. 
Dorsal profile C-shaped ; ventral feebly sigmoid ; thorax stout and 
curved ventrally but not differentiated from abdomen in diameter; 
abdomen bag-like. Spiracles small; diameter diminishing posteriorly. 
Integument of venter of anterior somites sparsely spinulose, the spi- 
nules minute and in short transverse rows. Body hairs very few: 
6 on Ti, 2 each on T2-AIV; 0.008-0.033 mm long, longest and 
with multifid-tip on Ti, becoming shorter and simple posteriorly. 
Head large; cranium subpyriform. Each antenna with three sensilla, 
each of which bears a spinule. Head hairs minute (about 0.006 mm 
long) , simple, six only, near mouth parts. Labrum twice as broad 
as long, bilobed, lateral borders curved; each lobe with five sensilla 
on the anterior surface, two contiguous sensilla on the ventral bor- 
der, and one isolated and three contiguous sensilla on the posterior 
surface; entire posterior surface moderately spinulose, the spinules 
minute and in short rows which are arranged in longer subtransverse 
rows medially, laterally the spinules are coarser and isolated. Each 
mandible heavily sclerotized, narrowly subtriangular in anterior 
view; of two portions: lateral thick and terminating in a long 
slender apical tooth ; medial blade arising from the anterior surface 
and bearing two sharp-pointed medial teeth. Each maxilla with the 
apex conoidal and bearing a few spinules; palp a low rounded knob 
with five sensilla; galea a short frustum with two apical sensilla. 
Labium feebly bilobed, with minute spinules in subparallel rows; 
each palp a low rounded knob with five sensilla ; an isolated sensillum 
between each palp and the opening of the sericteries, the latter a 
short transverse slit. Hypopharynx densely spinulose, the spinules 
minute and in short arcuate rows which are arranged in long sub- 
parallel transverse rows, base with numerous heavily sclerotized long- 
itudinal ridges. (Material studied: numerous immature larvae from 
New South Wales, courtesy of Rev. B. B. Lowery.) 
Tribe Cryptocerini 3 
revision : Posterior surface of labrum usually without spinules. 
Hypopharynx usually without spinules. 
3 In 1949, M. R. Smith concluded that the well established name Crypto- 
cerus, which had been in use for 146 years, was a synonym of Cephalotes ; 
he changed Cryptocerini to Cephalotini, Cryptocerus to Paracryptocerus 
and subgenus Cryptocerus to Harnedia. In four pages could anyone intro- 
duce more confusion into stable nomenclature? The old names should 
have been conserved. We refuse to accept any of these changes.
