18. Chaetodacus pubeseens sp. nov. Plate II, fig. 2. 
Chaetodacus scutellatus Bezzi (not of Hendel), Bull. Ent. Research 
7 (1916) 114. 
Much larger and more pubescent than the preceding species, 
and moreover distinct on account of the different pattern of 
thorax, legs, and wings ; it is closely allied to true C. scutellatus 
Hendel, from Formosa, differing only in the broader frons and 
in minor details of thoracic and abdominal markings. 
Luzon, Laguna Province, Los Banos and Mount Maquiling 
{Baker-). Type in Professor Baker’s collection. 
Male . — Length of body, 8.5 millimeters ; of wing, 8 . It seems 
to differ from Hendel’s description of C. scutellatus in the fol- 
lowing points : Frons broader, being not twice as long as broad. 
On back of mesonotum the yellow humeral call! surrounded with 
reddish, not with black; middle yellow longitudinal stripe 
broader than lateral ones. Abdomen with black basal bands 
only on second and third segments; fourth and fifth segments 
with only a broad black spot on each side. Opaque oval 
patches of fifth segment distinct; fifth segment, moreover, longer 
than usual, being only a little shorter than the two preceding 
segments together. Legs entirely reddish yellow and quite un- 
spotted, only the hind tibiae being brownish. Apical fuscous 
spot of costal border broader, extending below to middle of 
first posterior cell (Plate II, fig- 2 ) ; no distinct infuscation at 
lower end of hind cross vein or only a very much less-developed 
one. Pubescence of body longer than in any of the allied forms. 
Note. — In consequence of my mistake in regard to the Phil- 
ippine species here described as C. pubescens, the Japanese 
(and Chinese) species, to which Miyake 15 has recently given the 
name of Dacus bezzii, is probably the same as the Formosan 
C. scutellatus Hendel; at least I cannot distinguish them from 
descriptions and figures. 
III. Genus MELLESIS Bezzi, 1916 
All the species here comprised in the present genus are typical 
in having a well-developed basal stalk of the abdomen (except 
M. subsessilis) , an elongated first antennal joint, a mesonotum 
with interrupted suture and with no prescutellar bristles, and 
a scutellum with only the apical pair of bristles. They all have 
nonspinose femora, distinct lower orbital bristles (except M. 
bioculata) , and well-developed anterior supra-alar bristles. To
