I his is very niiicli like T. sa))i()ensis Alex., but seems fairly well distinifuislied by the lighter sides of ])raesciitum, ])resence of hind femoral sjhmdes, iwactical absenee of vliite at base of tibiae, and cdearer wings with more conspicuous stigma. O 98. Trentepohlia (Mongoma) albangusta, sp. n. Head as in T. fuscidujaia. Thorax nearly bare, bright ochreous-brown, somewhat shining. Praescutum with a broad but not very sharply-defined dark brown median stripe ; scutal lobes, scutelhmi and postnotum brown.

Tibiae dark brown, extreme base (0-3 mm.) and tip (0-6 mm.) whitish. Tarsi rather dark brown. Front femora with a few longish bristles near base beneath ; posterior femora with more numerous but shorter bristles. Winfis clear ; stigma hardly indicated ; veins dark. Cross-vein r meeting about its own length before the fork; R., less oblique than usual and over half as long as i?3 ; discal cell long ; cell retracted almost to middle of discal cell; basal section of M.> shorter than m ; Cuia just before base of discal cell; Cuo joining An more than half its length distant from wing-margin. Halteres brownish, base of stem ochreous. Wing- length 9 mm. Upolu : Malololelei, 2,000 ft., 2 $, 17.vi.1924, vii.1924.
