amata the plate is broader at end, with the median keel 
very strong, and the axillee have at most a few blue hairs.) 
Compared with C. reducta, Ckll., from Singapore, it is 
smaller, with the scutellum less deeply incised, the bands at 
sides of third abdominal segment entire (broken in reducta), 
and spots on fifth segment with posterior side oblique. 
Island of Penang (Baker, 9595). 
Were the range of this insect continuous with that of 
C. amata, it would be regarded as a local race or subspecies ; 
but as it occurs in an island so remote from Formosa, it 
may represent a parallel or convergent type, not derived 
from the amata stock. It is quite distinct from the other 
Penang species, C. ridleyi, Ckll., and C. callura, Ckll. 
Crocisa angulifera, sp. n. 
?.—Similar to C. decora, Smith, from Singapore, but 
differing thus: anterior spots on thorax separated by an 
interval equal to the length of one; median stripe narrower ; 
discal spots much smaller; axillz without spots; inner 
margins of scutellar lobes without a double curve; basal 
band of abdomen hardly half as broad ; angular projections 
of blue at sides of first segment very sharply pointed ; 
bands on following segments narrower, and truncate mesad. 
The black band on pleura is extremely broad. The basi- 
tarsi have blue hairon outer side. The scutellum is without 
blue spots. 
$-—Similar; going to C. emarginata, Lep., in Friese’s 
table, but with large teeth on hind femora beneath. 
Sandakan, Borneo (Baker, 9597, 9596). The female is 
the type. 
Xylocopa collaris, Lepeletier. 
A female from Sandakan, Borneo (Baker, 9603), has the 
band of white hair on thorax anteriorly narrowed, essentially 
as in subsp. penangensis. In a female from ‘‘ Wahnes S.,” 
South-east Borneo (Wolf v. Schoenberg), this band is very 
broad. Is this a matter of individual variation or dimor- 
phism, or are there two races in Borneo? The Sandakan 
insect is not penangensis, as it differs in the male. 
Trigona itama, Cockerell, variety a. 
A specimen from the Island of Penang (Baker, 9590) 
appears to belong to 7. itama, having a hairy scutellum and 
all the general features of that species. It differs in having
