Plant Indus. Bull. 149) Poly poms sulphur ens occurs chiefly on 

 oaks, chestnut, maples, black walnut, butternut, alder, locust, 

 apple and pear and is widely distributed throughout the United 

 States and Canada and in most of the forest regions of Europe 

 where it is regarded as a destructive parasite both on deciduous 

 trees and conifers.

Richness of Borneo in Coleoptera. 



"The great majority of the Coleoptera taken at Mount Merinjak 

 were again new to me, which goes to show how every hill and moun- 

 tain in a great island like Borneo must be thoroughly explored before 

 we have any idea of the tremendous wealth of species the island will 

 produce. Wallace during his stay in Borneo spent nearly the whole of 

 his time on the Sadong River in Simunjan, and collected nearly 2000 

 species of Coleoptera, of which nearly 300 were Longicorns. During 

 my short stay [six months] I obtained examples of approximately 

 3189 species, of which 369 were Longicorns, about 90 of these prob- 

 ably nov. spp. We must remember that Wallace was collecting prac- 

 tically all orders, whereas I was specializing more or less." [A table 

 of the number of species by families is given.] — G. E. Bryant in The 

 Ent. Mo. Mag., London, April, 1919.
