11. Cliaetodacus mcgregori sp. nov. Plate I, fig. 7. 
Allied to the preceding species, but distinct by the unspotted 
face, and strikingly characterized by the broad third antennal 
joint, and by the anal bulla in the wing of the male. 
Panay, Antique Province, Batbatan Island (McGregor') . 
This very peculiar species is named in honor of its collector. 
Types in my collection. 
Male and female . — Length of body, 5 to 5.5 millimeters; of 
ovipositor, 0.5; of wing, 4.5 to 5. Head and its bristles exactly 
as described for the preceding species, but no distinct dark patch 
on middle of occiput. Antennse a little shorter than face and 
with third joint broader than in the allied species; very broad 
in the male and clothed with very long pubescence, obliquely 
truncate at the end; entirely yellowish. Face quite unspotted. 
Back of mesonotum as in the preceding, but paler, the black 
stripes being less developed; yellow stripe uniting humeri with 
supra-alar stripe less marked and interrupted in front of suture. 
Pleura likewise colored, but propleural region more broadly 
reddish ; mesophragma with a reddish middle stripe. Scutellum, 
squamulse, and halteres as in the preceding. Bristles black, 
but scapular, mesopleural, and pteropleural yellowish. 
Abdomen as in the preceding, but first two segments without 
black sides; black middle longitudinal stripe present only on 
the last two segments, being quite wanting on third; in the 
female the fourth segment with a narrow black basal band, 
which is wanting in the male ; sides of last three segments black 
spotted in both sexes; oval patches of fifth segment indistinct 
in both sexes. Third segment of male ciliated; ovipositor very 
short and entirely of a pale reddish color. Legs as in the 
preceding, but even paler, the middle tibiae being quite yellowish 
and the hind tibiae being only darkened, not properly black. 
Wings (Plate 1, fig. 7) as in the preceding, but distinctly 
broader. Costal border equally shaped, but paler and more 
equal throughout, being not at all dilated at end of first posterior 
cell ; stigma much paler ; costal cell quite hyaline ; first basal cell 
only a little infuscated above second basal one; anal stripe less 
indicated in the female, in the male replaced by a shining, 
sharply separated bulla of a yellowish color, placed just above 
the prolongation of the anal cell, on its terminal half. Super- 
numerary lobe of male not much developed. 
12. Chaetodacus bakeri sp. nov. Plate I, fig. 8. 
A rather robust species, with an almost stalked abdomen,
