On some New Genera and Species of Coccidae

Published online by Cambridge University Press:  10 July 2009

Extract

Insects inducing galls. Adult female apparently without limbs or antennae. Mouth-parts obscure. Spiracles large and conspicuous ; two pairs, occupying a position close to the posterior extremity. Anal orifice minute, setiferous. Genital orifice sharply defined. Spiracles, anal and genital orifices all included in a densely chitinous area. This dense deposition of chitin renders the interpretation of the characters difficult and prevents any accurate definition of the genus.

* “ Perivulvar ” appears to be a more suitable term than either “ circumgenital ” or “ perivaginal ” for the pores surrounding the genital orifice.—E.E.G.

I have adopted this term, from the Italian writers, to describe the so-called pygidial “ lobes.”

“ Squamulae ” is here employed in the place of “ plates ” or “ squames.”
