Antennae and jialfii black, Hai^ellar seginents rounded to shortly oval, tei'iiiinal one a little longer. Proboscis shorter than head, labella yellow. / horax (in mature specimens) shining black, except the posterior pronotal angles, which are ochreous, and a large dull black patch on each side of the ])raescutuni, extending from ])seudosuture to suture. Abdomen dark brown, rather short. Hypopygium with the fleshy claspers large, the two rostral sjunes rather long and moderately stout. Valves of ovipositor ochreous ; cerci rather long, curved, })ointe(l. Legs dark l)rown, bases of femora ochreous. Wiiigs rather dark grey, stigma very small, indistinctly darker ; veins dark. »Sc I'liding well before base of Rs, which is short and curved, slightly shorter than basal section of R^ , Tij) of J?i turned upwards and shorter than r, which is straight. Cuici a little before fM, slightly oblique. Halteres with basal half of stem yellowish, the rest blackish. Wing-length 4 mm. Tutuila : Pago Pago, type A: paratyjjes 5 d', 8 $, 14.xii.PJ25. Upolu : Apia, 5 (^. 3 $, ii., iii., vii.l!J24 ; Malololelei, 2 q, o $, xi.PJ24, xii.1925. Savaii : Fagamalo, 1 $, viii.1925. This species belongs to a small group, of which several species are known t(j occur in the Malayan and Papuan regions ; of these, D. se)ninifa Edw. (New Helu'ides) is the nearest to the new' species ; it has the same colouring of the thorax, but differs consjiicuously in its bright red abdomen. D. sitHplissima Alex. (Java) resembles D. atromaculata in its shining black thorax, but apparently lacks the dull spots on the praescutum. All species W'hich, like the present, have only three posterior cells in the wing, have been referred by Alexander for convenience only to the subgenus Alexandriaria Garrett; there is probably no close relationship) between the Oriental forms and the North American species for W'hich Alexandriaria was introduced. 78. Dlcranomyia fijiana Alex. Ann. Mufj. Nat. IJiat., (U), xiii, p. 30, 1921. Upolu : Malololelei, 2,000 ft., 1 ^ and one broken specimen, 25.ii.1924 and vii.1924. In these specimens the wing-markings dilier slightly from the typ)e from Fiji, the small grey clouds in cells R- and R^ being situate on the veins instead](https://iiif.wellcomecollection.org/image/b29809071_0062.jp2/full/800%2C/0/default.jpg)
