at vertex; and in the face, which has only two black spots, of 
elongate shape, at the lower end of the antennal grooves. 
6. Chaetodacus ferruginous dorsalis Hendel, 1912. 
This is the palest-colored form among those separated from 
C. ferrugineus; it seems to be rather rare in the Philippines, 
being represented by a single female specimen. 
Luzon, Laguna Province, Los Banos {Baker). 
7. Chaetodacus ferrugineus occipitalis var. nov. Plate I, fig. 3. 
Male and female. — This new variety is darker colored than 
the preceding one, having darkened bristles, black mesonotum, 
black mesophragma, and black tibise ; but it is paler colored than 
the following one, having reddish occiput and entirely yellowish 
femora. The dark fore border of the wing (Plate I, fig. 3) is 
broader than in C. dorsalis and C. pedestris; it is usually con- 
tinued by a yellowish tint into the middle of the submarginal 
cell. The length varies from 7 to 8 millimeters. It seems to 
be the commoner form in the Philippines. 
Luzon, Laguna Province, Los Banos, Mount Maquiling and 
Mount Banahao {Baker) : Rizal Province, Manila {McGregor) . 
Panay, Antique Province, Batbatan Island {McGregor) . Min- 
danao, Davao {Baker). Types in Professor Baker’s collection. 
Specimens taken at Singapore by Professor Baker agree with 
this variety. 
Note. — In all these three forms (C. /. occipitalis, pedestris, 
and limbiferus) the oval patches of the fifth abdominal segment 
are shining reddish, like the surrounding parts. 
8. Chaetodacus ferrugineus pedestris Bezzi, 1913. Plate I, fig. 4. 
Male and female. — In the present variety the occiput is black 
in the center, with a yellow border on the sides; the bristles 
are nearly black; the submarginal cell (Plate I, fig. 4) is quite 
hyaline below the costal border, which does not surpass the 
second longitudinal vein in the middle or only a little so. The 
length varies from 6 to 7 millimeters, rarely surpassing 7 milli- 
meters in the female. 
It is probable that the present form is the ferrugineus re- 
corded by Osten-Sacken, being very common near Manila. It is 
closely allied to the common Indian form that I have described 
under the name C. ferrugineus incisus Walker, but may be dis- 
tinguished by the much broader yellow supra-alar stripe of 
mesonotum and the less-blackened abdomen.
