from L. ferox in having the head, body, femora and wings slightly 
darker ; venter less hairy ; ocelli slightly larger, more rounded and 
in contact with the eyes (in L. ferox the ocelli are very narrow and 
widnly separated from the eyes). The soldiers also are smaller tlian

Biology. Of the 32 colonies collected by Mr. Clark, 28 were 
associated with other species, as follows : -12 with Hamitermes .sp., 
6 with Hamitermes obeuntis Hilv., 4 with Eutermes apiocephalus 
hilv., 3 with Eutermes occasm Silv., 1 with Coptotermes sp., 2 with 
Coptotetmes sp., Hamitermes obeuntis and Eutermes apiocephat.us, aiid 
4 with Hamiteimes sp. and iMirotermes hraepelmi Silv. Alate imagos 
were found in March, April, and May. A brachypterous queen w^as

deeply notched in the middle. Meso- and metanotum broadly 
rouncled posteriorly, the former faintly sinuate in the middle.
