THE COCCIDJE 

 OF THE BRITISH ISLES. 



THIS sub-family is represented by the single genus 

 Conchaspis, of which only three species are at present 

 known. The insects comprising this aberrant genus 

 are chiefly characterised by both sexes forming a 

 separate covering-scale or puparium, as in the 

 Diaspinae, differing, however, in having no exuviae or 

 cast skins incorporated with the secretionary matter. 

 The adult female retains both limbs and antennas, and 

 has a biarticulate mentum ; and the tibio-tarsal joints 

 in both sexes are united. In his 6 Coccidaa of Ceylon/ 

 p. 20, Mr. Green suggests that the two-jointed mentum 

 in the adult female points to some affinity with the 

 Coccinaa. I feel, however, that the Conchaspinae are 

 more nearly related to the Diaspinae than to any other 

 division of the Coccidae. 



CONCHASPIS (Cockerell). 

 PSEUDINGLISIA (Newstead). 



This genus was established by Mr. Cockerell, but 

 his description * amounted to little more than a name. 

 In founding the genus Pseudinglisia five months later, 

 I gave the following diagnosis : 



" Scale elevated, more or less circular, ridged ; ven- 

 tral scale complete, detached ; antennae of. four joints ; 

 anal lobes very minute; last five segments of body 

 with broad chitinous plates bearing spinnerets; ros-
