hairy; hairs on anal valve somewhat longer than those on

Described from one male and one female. 
Type and allotype. — No. 18569, in Bureau of Science collection. 
Mindanao, Kolambugan, Bureau of Science accession No. 
18569, June, 1914 {Banks). Food plant not recorded. 
This species appears to be closely related to M. annata 
Crawford (’15: 264), but is distinguishable from the latter as 
follows: Presence of large, reddish brown spot along anal vein 
of forewings subbasad; genal cones slightly shorter than ver- 
tex; antennae shorter in comparison with width of head; and 
pronotum much shorter than vertex.

27, 30, and 31; Plate 4, fig. 40; Plate 5, fig. 55. 
Male . — Length of body, 1.76 millimeters; width of head, 0.48; 
length of antennae, 0.6 ; length of forewings, 2.88 to 3.04, width, 
0.96. Light yellowish brown. Dark brown as follows: Two 
irregularly linear markings running longitudinally cephalo- 
caudad from caudal margin of mesoscutum, near cephalic 
angles of mesoscutellum, to cephalic margin of mesopraescutum ; 
marginal areas of pronotum, cephalic marginal area of meso- 
praescutum, and submarginal areas of abdominal tergites and 
stemites I to V ; an irregularly diffuse spot marking each of the 
two foveae at vertex; apices of genal cones; distal portions of 
antennal segments IV and VI, proximal and distal portions of 
VII, the whole of VIII, except a very small, faintly yellow, 
basal portion, and the whole of IX and X. Apex of genital 
forceps and ungues brownish black. Distal tarsal segments 
in all legs yellowish brown. Body and appendages very sparsely 
and briefly pubescent. 
Head slightly narrower than thorax, somewhat declivous. 
Vertex about one and a half times as broad as long, cephalic 
emargination describing an angle of about 120° ; a rather 
deep, angular fovea on each side extending from caudal margin 
to proximity of base of antennal tubercles and located midway 
between median suture and lateral margin of vertex. Ocelli 
subconcolorous with vertex: anterior ocellus moderately large, 
fairly prominent; posterior ocelli somewhat smaller than ante- 
rior, a large portion basad hidden beneath cuticular surface. 
Eyes large and prominent, dark yellowish brown, subhemi- 
spherical, about as thick as distance from lateral margin to 
median suture of vertex. Genal cones small, about one-fourth
