The Apbrophorina), like the jMachasrotinse, have the anterior 

 margin of the pronotum rounded or angulate, and the eyes mode- 

 lately transverse, but differ by having the seutellum of ordinary 

 size, flat, and triangular. 



The Aphrophoriuae reach their maximum development in the 

 Ethiopian Eegion, especially in the genus Ftiiehis. Many of the 

 Aphrophorinse secrete a quantity of fluid and in the immature 

 stages emit this fluid in the form of bubbles, and are thus known 

 as " cuckoo-spits " or " frog-spits." These bubbles conceal the 

 insect, and are considered by some as exhibiting a protective 

 device. In Madagascar Pti/elus f/oiidoti has been reported to exude 

 so much fluid, that five or six dozen larvce can about fill a quart 

 vessel in an hour and a half. The Apbrophorina) are almost 

 universally distributed.
