262 THE COCCIDAE 



Since the adult females of all the species of this tribe are 

 enclosed in a puparium, it should be a simple matter to study 

 the pygidium of the second stage female which is that borne by 

 the puparium. Such a study was made by Lindinger and the re- 

 sults published in 1906. He figures in this paper and describes 

 the pygidium of the first and second nymphal stages and from 

 one to three types of that of the adult female. Nine species are 

 recognized and figured in this way and it is to be hoped that the 

 other species may soon receive a similar treatment. 



Leonardi in his revision published in 1906, as already noted, 

 subdivides the tribe into three genera, Leucaspis of which pini 

 Hartig is the type, Anamaspis of which loewi Colvee is the type, 

 and Actinaspis of which pusilla Loew is the type. The last two 

 of these genera he named as new and each includes only its type 

 species. The differentiation of these genera was not well made. 

 These names although stated to be subgenera in his analytical table 

 are designated as genera elsewhere. The following is a transla- 

 tion of the table by Leonardi: 



GENERA OF LETJCASPIDINI 



a. Pygidium provided with pectinae. 



b. Pygidium with lobes Leucaspis Targ. 



bb. Pygidium without lobes Anamaspis Leon. 



aa. Pygidium without pectinae. Actinaspis Leon. 



Lindinger in his synopsis recognizes eleven of the twenty 

 described species referred to the genus Leucaspis, of which he 

 figures and describes nine. Four of the species previously re- 

 ferred to this genus he places in the genus Lepidosaphes and the 

 remaining ten are referred to the synonomy or considered as 

 unrecognizable. The classification of Leonardi is discarded as 

 untentable and the genus is divided into two named sections, 

 Salicicola and Euleucaspis, which must of necessity be recognized 

 as subgenera. Salicicola includes the single species kermanensis 

 Lindgr., which is the type. The pygidium of the adult female 

 of this species is very similar to that of lowei Colvee, the sulci 

 Newst. of Lindinger. The remaining eight species are included 

 in Euleucaspis, for which pini Hartig may be taken as the type. 

 The section Euleucaspis is divided into two other named groups, 

 Pusillaspis and Suturaspis, which should also of necessity be con- 

 sidered as subgenera. Pusillaspif includes two species, pusilla 

 Loew, which may be taken as the type, and sulci Newst. Sutur- 

 aspis includes the remaining six species, of which pistaceae Lindgr.
