116 Mr. T. D. A. Cockerell—Descriptions and 
fuliginous as far as level of the orange-ferruginous stigma, 
beyond that milky-white ; hind tibize fringed with black 
hair. Abdomen shining dark reddish brown, the apical half 
blackened, venter pallid towards base. 
Sandakan, Borneo (Baker, 9964). 
Known from 7’. apicalis, Smith, by the black legs. The 
shiny head and thorax separate it from 7. collina, Smith. 
The distribution of Trigona in the Malay region is very 
extraordinary. From the Philippines we know only three 
species. Of these, two are from Palawan only. Borneo, on 
the other hand, has 25 species. More species are known 
from Penang than from the whole Philippine group. In 
Borneo, the species appear to be largely confined to limited 
areas ; thus among the numerous species from Sandakan are 
none of the nine described from Borneo by Cameron. The 
deficiency of species in the Philippines cannot well be due to 
lack of material, as Messrs. Baker and McGregor have sent 
me large collections from those islands. ‘That the Philippine 
bees are really fairly well known is shown by the fact that 
a fine collection from Panay, whence no bees had previously 
come, contained only two new things, a species of Nomia 
and a variety or race of Megachile. 
Trigona rufibasalis, Cockerell, variety a. 
Scape red only at base. 
Sandakan, Borneo (Baker). 
Trigona scintillans, sp. n. 
Worker.—Length about 38 mm., anterior wing 2°8 mm. 
Head, thorax, and abdomen shining black, not hairy; the 
face with’a little pale hair at sides, but not canescent ; 
Jabrum and mandibles bright ferruginous ; scape pale ferru- 
ginous in front, flagellum dark ; tegule very dark reddish. 
Wings hyaline, stigma and nervures dilute sepia. Legs 
black, the small joints of tarsi ferruginous. Abdomen 
broad. 
Sandakan, Borneo (Baker). 
Differs from 7. erythrostoma, Cam., by the smaller size 
and the stigma not black. Easily known from 7. atomella, 
Ckll., by the narrower head and non-canescent face. 
Melipona flavolineata, Friese. 
“Guyane, Maroni.” From Queensland Museum. 
Trigona clavipes (Fabr.) comes from the same locality.
