Burma and Ceylon. Jordan has described the majority of the forms 
from our limits. 
Eucorynus crassicornis, Fabr., is a dark coloured insect found 
not uncommonly in tree bark in the plains, while Phlceobius alter nans, 
Wied., has been found on plants. Arcecerus fasciculatus, de G., is 
cosmopolitan and has been recorded as breeding in Areca nut in India. 
It is stated to have been distributed in coffee beans in which it 
breeds freely. This, or a very closely allied species, breeds freely in 
old dried cotton seeds (Plate XXVII) that remain on the plant after 
picking, and we have reared very large numbers from such seeds. 
Another has been reared in dry chilli pods and a third from the stem of 
par war (Trichosanthes anguina). The cosmopolitan species feeds 
on a great variety of substances and is variable in appearance ; the 
discrimination of species is not easy in this genus.
