The material which forms the basis of this paper has been 

 assembled during the last three or four years, mainly through 

 the efforts of Mr. C. P. Clausen while engaged in a study of 

 Pseudococcus and related genera in California. In all, three new 

 genera and six new species are described, the types of which will 

 be deposited ultimately in the United States National Museum. 

 Notes on two foreign or introduced species under Tanaomastix 

 are included to complete the generic conception. 



Tribe MIRINI 



Acerophag'us^ Emily Smith 



Of the three species included in the material two are new and 

 all belong to the A. texanus group, the five species of which now 

 known may be separated as follows : 



Females 



1. Wings without a conspicuous cross band 2 



Wings with a smoky band across the disk A. fasciipennis, n. sp. 



2. Frontovertex about one-third to three-fourths longer than wide 3 



Frontovertex about twice as long as wide, the ocelli in an angle of 



about 85° A. notativentris (Girault) 



1 For a recent revision of this genus see Proc. U. S. Nat. Mus., vol. 50, 

 pp. 574-79. The antennal club of A. texanus (Howard), represented as 

 solid in figure 52, plate 31 {loc. cit.), in reality is composed of three closely 

 fused joints except in the male.
