prominent basal tubercles of first segment very well developed; 
punctulate and pubescent like back of mesonotum, but the 
first two segments clothed on sides with long, erect, whitish 
hairs. First segment entirely reddish, with less-distinct, dark- 
ish, longitudinal middle stripe; second segment reddish at base, 
yellowish on more than its apical half, with less-distinct middle 
stripe, and with no black spots at sides; third, fourth, and fifth 
segments entirely reddish, with no black spots on sides, with only 
a narrow and complete, black longitudinal stripe in the middle; 
venter very concave ; reddish, with brown apical sternites. 
Segmentation distinct; sixth segment not visible. Ovipositor 
reddish, very much swollen at base. Legs entirely reddish, 
with pale pubescence; tibiae paler, base of tarsi whitish; middle 
tibise with a strong black spur. 
Wings (Plate II, fig. 3) shorter than body, shining and 
iridescent; veins reddish; second longitudinal vein straight; last 
portions of third and the fourth parallel, the latter less curved 
at base; small cross vein placed beyond middle of discoidal 
cell. The pattern consists of a yellowish and broad, complete 
costal border, comprising even costal cells and extending below 
to third vein ; in first posterior cell this border extends below 
third vein to reach middle of cell and is more intensively dark; 
this darker, but less-sharply defined, apical spot continued below 
with a darkish shade, passing over fourth vein into upper part of 
second posterior cell. Stigma not darker; first basal ceil dark- 
ened above second. Yellowish anal stripe broad, but not ex- 
tending to hind border of wing. Second basal cell rather broad.

Very distinct from all the other species on account of the 
single hypopleural spot and the peculiar wing pattern. 
Luzon, Laguna Province, Mount Maquiling (Baker). Type 
in Professor Baker’s collection. 
Male . — Length of body, 10 millimeters; of wing, 8.5. Head 
as in the preceding species, but frons distinctly shorter and 
broader, being about as long as broad; of the antennae there 
is only the first joint, which is elongate and yellowish; black 
facial spots much smaller and rounded; cephalic bristles black, 
but it seems that the lower orbitals are very much less developed, 
only the first pair being distinguishable. 
Mesonotum distinctly narrower; entirely reddish on the back, 
with three very narrow, blackish longitudinal stripes and two
