No species of tliis family Inive liitlierto been recorded from Samoa, but Buxton and Ho])kins found several members of tlie genera P,sychoda and Bruucttia. Among the material available 1 have recognised six species, two of which are European and no doubt artificially introduced. The remaining four are described as new, but it is not improbable that some or all of them are wide- ranging species which have not yet been recognised elsewhere. For one of these species a new genus is proposed ; its breeding habits are not known, but the larvae are probably humus-feeders as is the case in Brunettia and Psychoda. No strictly aquatic species {Pericoma, Sycorax, etc.) have been found in Samoa, nor has any species of PJdebotomus. In Fiji the Psychodid fauna is richer than in Samoa, and among the material in the British Museum are examples of some very peculiar sjjecies as yet undescribed, but the only species so far recorded, in addition to those mentioned below, is Brunettia sexpiinctata Tonn. 62. Brunettia biformis, sp. n. Text-fig. 10. Head clothed above and on face with long erect blackish scales. Eye- bridges three facets wide, and separated by about the width of four facets. I^alpi with small dark grey scales. Antennae 15-segniented ; segments 3-13 with long necks, fully as long as the swollen basal portion ; verticils long, dense, and forwardly directed ; sense-organs very long, S-shaped, not very stout ; segment 14 with a shorter neck, but provided with verticil and sensory organs ; 15 smaller than 14, ending in a rather long point the tip of which is slightly enlarged and pubescent. Thorax clothed with long blackish scales towards the front ; scales on back part of scutum and on scutellum lighter. Front part of ])leurae, round prothoracic spiracle, considerably swollen and provided with a dense tuft of long black scales. Abdomen with dense blackish haii‘-like scales. Hyj)opygium very much as figured by Annandale for B. siiperstes, the ventral apjjeudages having 25-30 spatulate spines ; subanal plate (B of Annandale’s](https://iiif.wellcomecollection.org/image/b29809071_0048.jp2/full/800%2C/0/default.jpg)
