CHAPTER IV. 



CONCHASPIN^, 



As briefly diagnosed in the Synopsis at the end of the previous 

 chapter, the sub -family Co7ichaspince includes insects having a 

 separate covering -scale, formed entirely of secretionary matter 

 without admixture of the exuviae, the adult female retaining limbs 

 and antennae. The mentum dimerous. 



This division is represented by a single genus on\y—Con- 

 chaspis, the characters of which (as far as they are known) are 

 fully described below. 



CONCHASPIS, 'Cockerell. 



Conchaspis, Cockerell.— ' Coccidje, or Scale Insects,' Btilletin 

 Bot. Depart. Jamaica, Feb. 1893, p. 9.

 Coccid^,' Ent. Monthly Mag., July, 1893, p. 158. 



This genus is so aberrant, and so few species are known' 

 that no very definite diagnosis can at present be drawn up. Mr. 

 Cockerell has, apparently, given no formal description of the 

 genus. Mr. Newstead gave a short diagnosis in founding his 

 genus Pseudiglisia. His description runs as follows :—' Scale 

 elevated, more or less circular, ridged ; ventral scale complete, 

 detached ; antennae of four joints ; anal lobes very minute ; last 

 five segments of body with broad, chitinous plates, bearing 

 spinnerets; rostrum biarticulate.' Even this broad definition is 

 too narrow to admit the undoubtedly congeneric insect described 

 below, for the Ceylon representative bears three-jointed antennae, 

 and its scale is not ridged. 



I would suggest the following as a temporary diagnosis :— 

 Scale elevated, more or less circular ; adult female retaining limbs 

 and antennae, the latter of few joints ; genital aperture without 

 setiferous ring ; mentum biarticulate ; terminal segments of body
