This makes four species of Omiodcs now known to feed on 

 banana : blackbiirni on all the islands, meyricki on Hawaii, musi- 

 cola on Maui, maia on Oahu. They are closely related, all hav- 

 ing similar pattern on wings and no doubt have evolved from a 

 common ancestor. In a previous article I have mentioned dif- 

 ferences in color and degree of angulation of first line of fore- 

 wings. I have measured this angle in several specimens of each 

 species with the following results: In hlackhnrni it is 52°, in 

 meyricki 56°, in musicola 85°, and in maia 80°.

PAPER READ. 

 A Conspectus of the Fulgoridae of tfie Hawaiian Hemiptera. 



BY G. W. KIRKALDY. 



The Fulgoridae are all apparently endemic, and belong to 

 two genera, lolania and Oliarus, both belonging to the tribe of 

 Cixiini. 



Three longitudinal keels on the mesonotum; costal margin of teg- 

 mina strongly granulate . iolania 



Five longitudinal keels on the mesonotum; co^ial margin of teg- 

 mina not (or obscurely) granulate ^, Oliarus 



lolania Kirkaldy. 



1902, Faun. Haw., Ill, 118, PI. 5, f. 3. 



A reexamination of this genus presents only one species, per- 

 kinsi; the ground colour of the male tegmina is much yellower 

 than in the other sex. I separate ofif, as a variety (iiotata), the 

 form with a large brown blotch at the base of the tegmina of 

 the male.
