Briotocy.—This species is one of the most frequently encountered 
Trichoptera on Dominica and St. Lucia. It has been taken in the 
larger lowland rivers and the small tumbling mountain brooks. The 
immature stages were taken under stones in the fast water of riffles 
and cascades. 
Chimarra caribea, new species 
Figures 18-21 
This species appears to be the same as the one I have from the 
island of Trinidad and to be extremely close to C. duckworthi Flint 
from Costa Rica. The differences from the latter species lie in the 
narrower lateral lobes of the tenth tergites and the slightly more 
elongate clasper with a prominent thumblike apicomesal lobe in (@. 
caribea. Additional material from Venezuela and Colombia may show 
these differences to be clinal, but for the present I consider them 
specifically distinct. Chimarra antilliana is also related, but very 
distinct in the shape of both the clasper and the tenth tergum.
