suture. The mesonotum has distinct black 
markings. Legs: Chiefly reddish yellow, the 
hind tibiae are brownish. Wings: (See Bezzi, 
loc. cit., pi. 2, fig. 2) with a rather narrow costal 
band expanded into a moderately large spot 
at the apex. The cubital streak is broad and 
fills all the base of cell M4. A small brown 
spot is present at the apex of vein M3+4. 
Abdomen: With black basal bands on the sec- 
ond and third terga and with a median longi- 
tudinal vitta extending over terga three to 
five; these latter segments are black on the 
sides. 
Length: Body and wings, 8.0-8. 5 mm. 
The female has not been previously de- 
scribed. In most details it fits the description 
of the male as given in the original. The front 
is approximately 1.5 times as long as wide. 
The facial spots are elongate, pointed on their 
lower edges. The narrowed portion of the 
cubital cell is equal in length to vein Cui+lst 
A. Ovipositor: The basal portion when viewed 
from above {in situ) is approximately equal to 
the length of the fifth abdominal segment. 
The extended ovipositor (Fig. 28^) measures 
about 5.8 mm. The piercer is trilobed at apex 
(Fig. 28^) and has two long and two short 
preapical setae on each side; the distal pair 
is situated about O.O6 mm. from the apex of 
the piercer. The piercer measures about 1.74 
mm. long by 0.18 mm. wide at its widest 
point. The opening of the oviduct is situated 
about 0.25 mm. from the apex of the piercer. 
The inversion membrane measures about 2.36 
mm. long by 0.31 mm. wide, and the rasper 
extends to within 1.0 mm. of the base of the 
segment. The basal segment measures 1.69 
mm. by 1.32 mm., and the spiracles are lo- 
cated 0.36 mm. from the anterior lateral mar- 
gins of the segment. 
TYPE LOCALITY: Laguna Province, Los Ba- 
nos and Mt. Makiling. 
We have studied a specimen in the U. S. 
National Museum labeled "Mt. Makiling 
(another spelling for Maquiling), Luzon 
(Baker).” This is probably the type. We have 
also seen it from Manila, 1909 (G. Compere), 
and from Mt. Makiling, Laguna, Luzon, Jan. 
26, 1921 (G. C. Ladrera).

(Bezzi), n. comb. 
Chaetodacus scutellinus Bezzi, I916, Bui. Ent. 
Res. 7: 113, pi. 2, fig. 11. 
This species is related to D, pubescens (Bez- 
zi) and to D. trimaculatus n. sp. It is consider- 
ably smaller than either of these species. It 
is differentiated from the former by lacking 
the two presutural yellow vittae and by not 
having the costal band expanded at the tip of 
the wing. It differs from trimacidatus in having 
the costal band comparatively broad and the 
mesonotum chiefly black. It has been ade- 
quately described by Bezzi (1919: 432-433) 
except for the characteristics of the ovipositor. 
Length: Body and wings, 5. 0-5. 5 mm. 
TYPE locality: Laguna Prov., Mt. Makil- 
ing, Luzon. 
One female in the U. S. National Museum, 
labeled in red, from the type locality, is prob- 
ably the type although it has never been 
marked as such. 
This species was not represented in the 
collections at hand; the senior author has 
studied the above-mentioned female at the 
U. S. National Museum. 
Dacus (Zeugodacus) terminifer Walker 
Dacus ter mini fer^dSL^s, I860, Linn. Soc. Lon- 
don, Proc. 4: 152. 
This species appears to fit closest to D. 
pendleburyi (Perkins) but is distinguished by 
its all-black face. 
Dr. John Smart and Dr. K. L. Knight have 
re-examined the type and have supplied 
enough information so that it can be placed 
fairly accurately. The face is uniformly black, 
and the front has two pairs of inferior fronto- 
orbital bristles. Only two postsutural yellow 
vittae are present on the mesonotum, and the 
scutellum is yellow with a black basal band. 
The legs are chiefly brown to black with the
