stinging darts from more or less prominent processes. The green one, already 
mentioned, can afford a good example of a stinging response to an external 
stimulus. If the stimulus happen to be our forehead, or the back of our hand

Among the Geometers death-feigning is often resorted to. They grasp 
the stem, say, of their food-plant with their abdominal feet and claspers, and 
allow themselves to project stiffly and motionlessly from it, so that they re- 
semble dry twigs or sticks. 
The Tinzgeriide is said to be one of the least known families of the Lepi- 
doptera. So far I have bred but one species, and this from caterpillars T 
found feeding on the underside of tender leaves of Pisonia inermis, within a 
dense elongate white web, somewhat like that of some Attids (leaping spiders). 
The food-habits and pupating habits of caterpillars must be left over for 
treatment in a future article. 
In bringing this article to a close I have to thank the Curator of the Museum 
as well as ite offiial in charge of the Herbarium at the Botanic Gardens for 
the kindness they have always shown in naming for me the food-plants ot 
caterpillars I rear.
