indistinctly dark-bordered. Base of cell Ro markedly nearer 
the wing-base than that of cell M,; ; Cu,+ Ms; nearly twice 
as long as Ry,3. Halteres with pure white stem and dark 
brown knob. 
Length of body or wing 4°5-5 mm.

British Museum from Tokyo, Japan (C. H. B. Wood). 
This species differs slightly from 4. notata, de Meij., and 
E. javanensis, de Meij., in venation ; it resembles the latter 
in coloration, but the tips of the femora and tibie are not 
white. 
Erioptera (Erioptera) alboguttata, sp. n. 
(Pl. XII. fig. 4.) 
Head yellow ; proboscis, palpi, and antenne black. An- 
tenne not much longer than the head, flagellum very slender, 
with rather short hairs. Thorax: pronotum yellowish. 
Mesonotum ochreous brown, rather darker on the margins. 
Pleure: light ochreous, with an ill-defined dark brown longi- 
tudinal stripe in the middle, ground-colour rather darker 
below this stripe. -Addomen dark brown, genitalia (fig. 4) 
orange. Legs entirely yellow (front legs and hind tibie and 
tarsi missing). Wings brown, costa yellowish. A white 
spot over the base of Rs; a white band over the cord; a 
large white spot on the costa just beyond this; five or six 
smaller white spots on the margin round the apical part of the 
wing, and another white spot over the apical half of cell, 
Ist M., and the bases of cells M, and 2nd My. Cu,+M; 
nearly three times as long as Rp,3. Cell Ist M, open on one 
wing, closed on the other. Cuya slightly recurrent (¢. e., in- 
wardly oblique), joining M; a little beyond the fork. 
Length of body 3 mm. ; wing 3°5 mm.

This is a most interesting species, since its venation would 
place it, according to Osten-Sacken’s table, in the subgenus 
Lrioptera ; whereas in its spotted wings and recurrent Cua 
it is clearly related to Mesocyphona. ‘The discovery of this 
species adds support to Alexandei’s view that Mesocyphona 
should not be regarded as more than a subgenus of Hrioptera. 
Williston’s Z. annulipes from St. Vincent is another species 
of this group. 
Gonomyta (Lipophleps) nebulosa (de Meij.). 
- Arisan, 10. x. 1912 (I. Nitobe), 2 9. 
An immature male taken at the same time and place may 
also belong here.
