Transformation to the adult takes place within the mine, 

 usually where it is in the midrib. 



Proterhiniis phytlohius Perkins, which similarly mines the 

 leaves of Broussaisia arguta on Tantalus, Kaumuahona and 

 Olympus of the Koolau Range, does not make circles as above 

 when ovipositing. The chewing on the leaf for material to 

 cover the egg is done irregularly. This is the insect treated of 

 in "A Leaf-Mining Proterhinus" in Proc. Haw. Ent. Soc, 

 11:212 and 226, 1913. The name P. excrncians there used for 

 it was apparently an error in determination.
