xv, 5 Bezzi : Fruit Flies from the Philippines 429 
like those of the preceding one, but they are at once distinguished 
by the larger size, the black patches of the back of mesonotum, 
the four scutellar bristles, and the hind cross vein of the wings 
being not bordered with fuscous. In the last character they 
agree with the variety C. c. nubilus Hendel, from Formosa; but 
as I have said in another place, 13 I have never seen specimens 
with broadly infuscated hind cross vein, in opposition to what 
is stated by de Meijere. 14 The Philippine specimens with in- 
fuscated cross vein belong to the next, very distinct species, 
C. mundus.

Near the preceding species and closely allied to the Formosan 
C. synnephes Hendel, but distinguished by the unspotted face 
and the longer ovipositor of the female.

Baker’s collection. 
Male and female. — Length of body, 6 to 6.5 millimeters; of 
ovipositor, 1.8 to 2; of wing, 6 to 6.5. Occiput rather convex 
and shining, yellowish, with a broad reddish brown or blackish 
patch on each side in the middle; sometimes blackish, with a 
broad yellow border. Frons of usual shape, less than twice as 
long as broad ; dull yellowish, shining on sides and at vertex ; 
ocellar dot black, lateral and central darkish spots less developed 
or even wanting. Lunula reddish brown. Antennae as long as 
face, first joint short and third narrow and linear, very shortly 
pubescent; yellowish, with third joint broadly infuscated above 
and at end. Face shining yellowish and quite unspotted; cheeks 
linear; jowls as broad as third antennal joint; subocular spot 
small, brown. Palpi broad, yellowish; proboscis dirty brown. 
All the bristles black ; usually two terminal pairs of lower orbital 
bristles, very close together and the anterior one much smaller 
and sometimes wanting. 
Back of mesonotum black, punctulate, with pale yellowish pu-

grayish dust ; beyond the suture three broad yellow longitudinal
