Genus Fraserella, new name 
Fraseria Malloch, 1932, Ann. Mag. Nat. Hist., vol. 10, no. 10, p. 309 [type by 
original designation: F. fulvomaculata Malloch]—Séguy, 1937, Genera insec- 
torum, fase. 205, p. 3878. [Preoccupied by Fraseria Bonaparte, 1854 (Aves).] 
Both Malloch and Séguy have referred this genus to the Muscinae, 
although it is not very conformable therein. The thoracic squama, 
being in close contact with the base of the scutellum and with straight- 
ish apical margin, would seem to indicate such a reference. In 
Séguy’s key (1937, p. 370), the type species traces easily by its hairy 
eyes; the two additional species I am including at this time, however, 
have eyes that are scarcely hairy at all and will therefore run to 
Mesembrina or Muscina. Malloch, in his unpublished key to world 
genera of Muscidae (now on file in USNM), compares Fraseria to 
Mesembrina and distinguishes the former by its bare pteropleuron. 
Malloch, however, also brings out Fraseria in two other places, 
comparing it in the first instance with Bryantina and Balioglutum 
(distinguished from those genera by its wholly hairy arista, lack of 
any seta on wing veins except costa, and 4 postsutural dc) and in 
the other instance with Gymnodia (distinguished by plumose arista 
and strong presutural acr). Fraserella resembles Muscina in many 
respects, but the flattish abdomen and quite differently bristled ¢;, 
including a distinct calcar, of Muscina separate it from Fraserella. 
The new species described below is not very similar to F. fulvomaculata, 
but it fits no better with any other genus than Fraserella and hardly 
seems distinct enough to require a new genus. I am indebted to 
Roger W. Crosskey, Commonwealth Institute of Entomology, London, 
for notes on the type of F. fulvomaculata and for pointing out that 
Phaonia corbettt Malloch should also be referred to Fraserella. The 
development of the latter species was described by J. S. Sewill (1931, 
pp. 233-235) as taking place in the inflorescence of nipa palms and 
it is possible that the new species has a similar habitat. 
Fraserella altivolans, new species 
Figures 3, 4 
Ma.e.—Length of wing 8.25-8.5 mm. 
Color generally black; 1st, 2nd, and base of 3rd antennal segments 
reddish; oral margin between vibrissae reddish; infraocular bare area 
brownish; all bristles and hairs black, except very short whitish 
marginal cilia of thoracic squama. 
Head proportions (fig. 3c): front at narrowest part 0.115 of total 
width of head; medifacies strongly narrowed at insertion of vibrissae; 
arista as in figure 3d, long plumose; anterior ommatidia approximately 
twice as great in diameter as posterior ones; bristles and hairs similar
