Genus Glacialoca nov.
Genotype: Glacialoca caerulea sp. nov.

I propose here a new genus for the reception of a peculiar species found on the moraine of the Franz Josef Glacier. The genus is closely related to Bromacanthus Schött, from which it differs in having a mucro with only two teeth.

Scaled species, the scales similar to Paronana, but narrower and somewhat more coarsely ciliated. Dens with at least one row of stout serrated spines. Mucro two toothed.

One species only of this genus is so far known.

Glacialoca caerulea sp. nov. Plate 67, figs. 453–455.

Colour: Blue, with an ochreous transverse band anteriorally on Abd. V and some ochreous colour showing through on the head. Antennae I and II blue, furcula yellow, basal leg segments yellow, distal blue, ocelli on black fields.

Clothing: Of short plain setae on body, short ciliated setae around tip of abdomen, short and long plain setae on legs, short ciliated setae on antennae, short ciliated setae and long plain setae on furcula.

Body: Length 2.5 mm. First antennal segment longer than head. Ant. I: II as 23: 35. Ocelli, eight to each side, the posterior

inner two smaller than the remainder, which are large and equal. Ventral tube long and cylindrical. Abd. IV six and a-half times longer than Abd. III. Tergum of mesothorax completely covers prothorax.

Legs: Claw with two small outer lateral teeth at about one-quarter down; a pair of small inner teeth at one-quarter and a large single tooth at two-thirds. Empodial appendage narrow at base, widening and then becoming lanceolate and sharply pointed, reaching to distal tooth of claw. A single broadly-clavate tenent hair, slightly shorter than claw, to each foot.

Furcula: Manubrium to mucrodens as 29: 41. Dens with two irregular rows of short, stout, serrated spines for about half its length. Mucro with two blunt teeth, the apical much longer than the pre-apical.

Locality: Franz Josef Glacier, among bare stones of terminal moraine well removed from any vegetation.

Type: Slide 3/887, Dominion Museum Collection.

Remarks: A rare insect difficult to catch. The above description is taken from the single specimen I was able to secure and which, unfortunately, has lost the distal segments of its antennae. Although I observed other specimens they got away among the loose stones.
