Cockerell: Malayan Bees 
621 
tures; rather thin pale hair bands at bases of second and 
following segments; fourth ventral segment with large tufts of 
yellowish white hair. 
Singapore ( Baker 9984). A very distinct species, perhaps 
rather approaching H. cattulus Vachal (not catullus, as Bingham 
has it), but known by the red abdomen. Halictus himalayensis 
Bingh. has the greater part of the abdomen blood-red, and 
seems to be somewhat related. 
Anthophora caldwelli Cockerell. 
Malay Peninsula, Selangor (Baker), one male. Described 
from Foochow, China. The specimen is smaller than Chinese 
males, but the difference is probably not racial. 
Coelioxys siamensis Cockerell. 
Malay Peninsula, Selangor (Baker). Described from Trong, 
Siam. 
Prosopis feai Vachal. 
Penang (Baker). One female, having the scutellum immac- 
ulate, and the apical yellow mark on clypeus obtusely trian- 
gular. As at present understood, P. feai is quite variable, and 
with more material it may be possible to distinguish more 
than one species. Bingham erroneously describes the clypeus 
of the female as yellow; Vachal indicates that there is only a 
yellow spot. Bingham’s figure also shows the spot. 
Prosopis penangensis sp. nov. 
Female. — Like the Philippine Islands P. opacissima Ckll., but 
easily known by the polished, shining scutellum, with some very 
large punctures along the sides. The first abdominal segment 
is polished and shining, with excessively minute punctures. 
The yellow clypeal mark is large and oblong, and the lateral 
marks are broad-cuneiform. The middle and hind basitarsi are 
yellow but the anterior ones are brown. This is a much smaller 
species than P. feai, with entirely opaque mesothorax. In the 
Indian fauna it seems nearest to P. scutula Vachal, but the ner- 
vures are not pale testaceous yellow, and the tegulee are brown 
with a large yellow spot anteriorly. The yellow band on pro- 
thorax is interrupted. The eyes are brown.
