(All in ANIC). <i>Measurements</i> Hind wing~.-Average length, male, 29.8 mm (range 28.1-31.5 mm); female, 31.5 mm (range 29.9-33.1 mm). <i>Pterostigma</i>.- <i>Average</i> length, male. fore wing 1.88 mm (range 1.70-2.06mm), hind wing 2.14 mm (range 1.98-2.30 mm);female, fore wing 1.96rnni (range 1.86-2.10mm), hind wing 2.23mm (range 2.08-2.48 mm). <b>Comparisons between the two species of</b> <i>Episynlestes</i> <i>Diagnosis</i> <i>E. cristatus</i> is significantly smaller than <i>E. albicauda.</i> The males of <i>E. cristatus</i> can be distinguished in addition by the dissimilar quadrilaterals of the fore and hind wing, the more proximal petiolation of the hind wing, the subdivision of the radial field behind the pterostigma into small, pigmented cells and the substantial, crested upper branch of the superior appendage. The females of the two species resemble one another closely. but the smaller pterostigmata of <i>E. cristatus</i> appear to be diagnostic. <i>Habitats</i> The habitats of the two species appear to be very similar. Tillyard (1913) described the habitat of <i>E. albicauda</i> in the rain forest on Tarnborine Mt, a densely shaded area in which the sombre coloration of the insects provided an extremely effective camouflage. <i>E. cristatus</i> is similarly associated with small streams in rain forest, although it may occur in shaded situations along more open watercourses, as along the McLeod River. Like <i>E. albicauda,</i> it is well camouflaged, both perched and in flight; as is common among chlorolestids, flight may be rapid, but is rarely sustained, and specimens can be gathered by hand.
