MONOPHLEBIN^E. 



Mr. Maskell * gives the following diagnosis of this 

 subdivision : " Adult females active or stationary ; 

 naked or covered with mealy, cottony, or waxy secre- 

 tion ; segmented ; antennae of ten or eleven joints ; 

 anterior pair of feet similar to the rest ; ano-genital 

 ring without hairs ; anal tubercles inconspicuous. 



" Males with faceted eyes and no ocelli." 



In order to include a congeneric insect possessing 

 seven joints to the antennae, Mr. Maskell t subsequently 

 modified his diagnosis of the antennal formula, making 

 it "antennae usually of eleven joints." 



The principal genera included in this subdivision of 

 the Goccidde are Monophlebns, leery a, Walkeriana, 

 Ccelostoma, Callipappus, Paldeococcus, etc. The only 

 representative which has been found in this country is 

 leery a degyptiacum, Douglas.
