with black ocellar fields joined by a black line across the front of the head and between the antennal bases. Legs and furcula always light yellow, the former sometimes tinged with brown. Ant. I yellowish or pale violet, II violet, III and IV very dark violet. Sometimes with a narrow line of dark violet along ventral edges of thoracic pleura Abds. I-III and on the sides of the head.

Clothing: Heavily clothed with ciliated setae and with many long, flexed setae dorsally on head and body. Setae of legs, furcula and antennae all ciliated, but those of Ant. IV shorter than the others.

Body: Length up to 1.3 mm. Antennae twice as long as the head, the four segments related as 4:10:9:14. Ocelli eight to each side; the anterior pair very large, posterior inner pair small, remainder medium. Abd. IV three to three-and-a-half times as long as Abd. III.

Legs: Claw with four inner teeth, being a large pair just beyond centre, a large single tooth at three-quarters, and a very small tooth near apex. A single outer tooth at one-third down outer edge from base. A single strongly clavate tenent hair as long as the claw to each foot. Empodial appendage narrow and from one-third to one-half as long as claw, truncate on inner margin.

Furcula: Reaching forward to ventral tube. Manubrium to mucrodens as 15:20. Dens annulated and corrugated, the unannulated portion three times as long as mucro. Mucro relatively very small, bidentate, the teeth equal, and with a basal spine. The uncorrugated portion of dens strongly but very finely serrated and annulated.

Localities: Hastings, in lawn and under the floor of old shed (Coll. R. Forster). The species was present in large numbers. Makara Coast, under stones on beach; very common (Author's Coll.).

Type: Slide 3/1108 and Figured Paratype Slide 3/1041, Dominion Museum Collection.

Remarks: This species is closest related to P. interfilixa. The key for the separation of the species of Pseudentomobrya on p. 366 of the Collembolan Fauna of New Zealand can be amended to include this species by adding the words in black print as follows at 4:—

4. Claw with four inner teeth and one outer tooth. Abd. IV 3–3 ½ times as long as Abd. III. P. intercolorata sp. nov.
Claw with two small outer lateral teeth one-fifth down, no inner teeth. Abd. IV 6–8 times longer than Abd. III. P. interfilixa.Salmon.
