Coccophagus cowperi Girault is the common form in the vicinity 

 of Cape Town. This form can not be satisfactorily separated from 

 certain individuals found in North America which are referred to 

 C. lecanii (Fitch). The specimens at hand seem to indicate that 

 C. cowperi Girault is intermediate between G. eleapMlus Silvestri, 

 C. pulvinariae^ new species, C. isipingoensis, new species on the 

 one side and C. lecanii (Fitch) of North America on the other side. 

 C. pulvinariae, new species and C. isipingoensis, new species are 

 represented in the collection of the Citrus Experiment Station by 

 good series of specimens that do not show any intermediates, yet the 

 two forms co-exist and are recorded from a common host. Coccus 

 hesperidyym Linnaeus. 



KEY TO THE MALES OF CERTAIN SPECIES CLOSELY RELATED TO COCCOPHAGUS LECANII (FITCH) 



1. Femora or tibiae of all or at least one pair of legs marked with blackish 



or brownish 2. 



All femora and all tibiae yellow, only the middle and hind coxae black. 



pulvinarlae, new species. 



2. Femora of at least one pair of legs marked with blackish or brownish 3. 



All femora and fore and middle tibiae yellow. Middle and hind coxae black. 



Hind tibia mostly black, the apex yellow isipingoensis, new species. 



3. Fore and middle femora yellow 4. 



All femora mostly black, the ends tipped with yellow. All coxae black. 



Fore and middle tibiae yellow. Hind tibiae more or less extensively 

 suffused with blackish at base lecanii (Fitch). 



4. Hind tibia predominantly black, yellowish at apex 5. 



Hind tibiae yellow, hind femora mostly black, yellow at apex. 



cowperi Girault.^ 



5. Hind tibiae as well as the hind femora mostly black or dark brown. All 



coxae black. Fore and middle femora and tibiae yellow. 



eleaphilus Silvestri. 



The following description applies to what is considered a typical 

 specimen of C. lecanii (Fitch) from North America. 



Female. — Face, cheeks, and frontovertex predominantly blackish 

 or brownish, the latter with a pattern of orange colored lines. Scape 

 and pedicel fuscous, the flagellum yellowish. Apical two-thirds of 

 scutellum and the median piece of the metanotum bright lemon yel- 

 low, the remainder of thorax and abdomen black. All coxae black. 

 All trochanters yellow. All femora with a sharply defined narrow, 

 yellow annulus at base and at apex tipped with yellow, the yellow 

 more extensive at the apices of the fore and middle femora than on 

 the hind femora; the intermediate parts blackish. Fore tibiae pre- 

 dominantly yellow, more or less suffused with fuscous near the base. 



^^ The males of G. japonicus Compere run to cowperi in this key yet the two forms are 

 undoubtedly distinct as the females offer good characters for their separation and the 

 larvae are unlike.
