entire middle of sixth. Venter yellowish except apically. Face 
narrow, polished; flagellum dark, only moderately long; meso- 
thorax smooth and polished, punctured anteriorly; tegule rufo- 
testaceous; wings strongly reddened; stigma long, piceous; 
apical plate of abdomen fulvous-margined, broadly rounded, ob- 
tusely subangulate at sides, faintly subangulate in middle, but 
wholly without a salient point. 
BorNEO, Sandakan. Readily known from C. flavopicta Smith, 
from Sarawak, by the smaller size and yellow pleura. It is 
perhaps nearest to the much larger C. ridleyi Cockerell, but 
differs in a number of characters.

Sandakan is the type locality of those marked with an asterisk. 
The Sandakan bees seen by me include fourteen genera and 
forty-two species. One of the genera (Heterapis) has not been 
found in the Philippines. Of the species, only twelve are also 
known from the Philippines, and in two of these the Sandakan 
insect is a distinct variety. The species described as new from 
Sandakan number nineteen. 
Hewitt sent Cameron many bees from Sarawak. None of 
the new species described by Cameron are in the Sandakan 
collection, except Allodape hewittii, which is represented by an 
apparently distinct variety. 
One would expect to find resemblance between the Sandakan 
fauna and that of Palawan. The bees known from Palawan are 
the following ; those marked with an asterisk are not known from 
any other island:
