ART. 12. MASKELL GENERA OF COCGIDAE MORKISON. 83 



Besides the type species, a variet}^ has been described by Fuller, 

 but the writers are able to contribute nothing regarding the latter. 

 The following generic diagnosis has been based to the description 

 of the type species. 



GENEIUC DIAGNOSIS OF cnYX'TES. 



Coccine forms (of the Fernald Catalogue), adult female naked, 

 globular, with anal cleft completely fused, antennae 8-segmented, 

 legs, spiracles and mentum normal, the latter 1-segmented, marginal 

 setae small, tapering, irregularly arranged, spiracular spines very 

 short, stout, and blunt, not more than two opposite any spiracle, 

 dorsal body setae few and scattered, derm pores confined to long 

 tubular ducts and multilocular disk pores of two sizes, anal plates 

 half oval with large dorsal, subapical and apical and ventral ridge 

 setae, no fringe setae, no hypopygial setae, anal ring located below 

 and v.'ithin anal plates, small, oval, with numerous (about IG) setae; 

 larva elongate, antennae 6-segmented, legs, mentum and spiracles 

 normal, marginal setae large, blunt- tipped, curved or bent back- 

 wards, spiracular spines stout, very short, blunt-tipped, two oppo- 

 site anterior, normall}'^ one opposite posterior spiracles, anal plates 

 with very long apical setae and large dorsal, subapical and ventral 

 ridge setae, no hypopygial setae, anal ring with six setae. 



The form of the male pupa case and the structural characters of 

 the female and larva as given above are quite sufficient to isolate this 

 species generically, and the male pupa case, as described and figured 

 by Maskell and commented on by Cockerell, at least indicates the 

 possibility that G. haccatus digresses widely from the normal Coccine 

 type. To the best of the writer's belief, Kermes acaciae Maskell 

 represents a mixture of this species and of some species of EHococcus^ 

 the immature stages, as described by Maskell being of the larva and 

 adult of the Eriococcus^ while the adult of Maskell is the adult of 

 Cryptes haccatus. In view of the known host habits of Kermes.^ this 

 is a logical expectation, and the writers propose the synonomy indi- 

 cated, subject to future revision.
