Fig. 1. — Coffee plantation on the Kona slopes of Hawaii. Fig. 2.— A fruiting branch. 

 Fig. 3. — Low type of coffee tree. Fig. 4.— Coffee cherry cut to show the two large 

 beans which are of commercial value, and the very thin outer pulp. This pulp is the 

 only portion of the cherry eaten by the fruit-fly larvae. Note that the well-grown 

 larva; illustrated feed so close to the papery epidermis that parasites have no difficulty 

 in ovipositing in them. Thousands of acres are densely planted to coffee on the island 

 of Hawaii and offer food for the fruit fly the year round. (Original.)
