![the size of both male and female. The species is leather well distinguished by the six scntellar liristles, and the oclireous thorax with five rather narrow blackisli stri])es , these stri])es, however, are much more distinct in some specimens than in others. ! he male claspcrs are very short; the antennal Hagelliim is entirely dark, and the segments are not much longer than broad. h. Sciara, sp. inc. Upolu ; Malololelei, I 25.iv.1924. A small s[)ecies something like the last, but the mesoiiotum more shining and less distinctly strij)ed ; antennae longer, thigellum pale at base. 10. Sciara, sp. inc. rntuila : Pago Pago, 1 14.xii.l925. Savaii: Matavanu Crater, 1 $ (Bryan). Another small species, dark-coloured and with no spiecial distinctive features. ll. Phorodonta pollticollis, sp. n. Head black, slightly shining. Eye-bridges touching and 5 facets wide. Middle ocellus touching eyes. Palpi dark brownish. Antennae black, flagellar segments fully twice as long as broad, without necks, pubescence short. Thorax brightly shining black. Dorsocentral and acrostichal bristles unusually long and stiff, in single rather irregular rows, black. Scutellum bare above, margin with 6-8 strong black bristles. Abdomen dark brown, black-haired, not so short as usual in this genus ; lateral membrane ochreous. Leys yellowish, tibiae and tarsi darkened ; spurs yellowish, nearly twice as long as the tibial diameter. First segment of front tarsi barely two-thirds as long as the tibia. Claws very small, with median thickening. Coxae long, as in other species of the genus. Winys rather narrow, membrane rather dark brownish, all veins darker ; branches of M and Cu setose. Costa reaching two-thirds of the dis¬ tance from Rs to Mi. Ri and R subequal in length. Ry ending above fM. An absent. (Base of cubital fork below middle of basal section of M in the tyjje, but below base of r-m in the second specimen.) Halteres black, base of stem ochreous. Wing-length 3-5 mm. ; body 3 mm. Fpolu : Apia, 1 $ (type), 29.iii.1924. Savaii : Salailua, 1 $, 13.V.1924 (Bryan).
