190 THE COCCIDAE 



cles, and the enveloping of the female in a sac open only at the posterior 

 end are responsible for its location in this subfamily. 



Olliffia Fuller, — There is a single species, eucalypti Fuller, from 

 West Australia on Eucalyptus. The genus is generally placed in the 

 Eriococcinae. The form of the anal lobes and the shield-shaped dorsal 

 lip, similar to that found in Cerococcus, suggested its present location 

 and the possibility that it may not be an adult female that is figured. 

 The nymphal stages are unknown. 



Olliffiella Ckll. — A single species, cristicola Ckll., from New 

 Mexico, where it produces galls on the leaves of oak is included. The 

 presence of octacerores suggested its present location. This genus was 

 originally associated with the Australian gall making coccids of the 

 genus Cylindrococcus and Sphaerococcus and later with the Eriococcinae. 

 The tarsi consist of a single segment according to P^'erris and not two 

 as described by Cockerell. The antennae of the adult female consists 

 of five to six segments and of the first nymphal stage of six segments. 

 The anal ring of the adult female is without anal ring setae and the 

 first nymphal stage is provided with six anal ring setae. Ferris records 

 the presence of ventral octacerores and considers this genus as related 

 to Kermes. 



Amorphococcus Green. — This is a Ceylonese genus, including a 

 single species, mesuae Green, on Mesua. Ferris has referred leptospermi 

 Maskell, described as a species of Sphaerococcus from New South Wales 

 on Leptospermum to this genus. 



Frenchia Maskell. — Two species, casuarinae Maskell and semi- 

 occulata Maskell from Australia on Casuarina, belong to this genus. Its 

 present position was suggested as probable by Green.
