Adult female enclosed in a dense waxy test, with or without waxy or 
filamentous processes. Posterior extremity with a stout upturned tubular 
extension, at the apex of which is the anal aperture. 
Adult female insect with the terminal abdominal segments usually abruptly 
narrowed. The extremity with two stout spiniferous lobes, each bearing a 
longish seta ; the interno-ventral aspect of the lobes more densely chitinous ; 
a prominent median triangular plate on the dorsal aspect ; anal ring with eight 
stout hairs. Antennz rudimentary. Limbs rudimentary or absent. Mentum 
dimerous. Derm with conspicuous paired (8-shaped) glands.  Cribriform 
plates present on the dorsal surface of the abdomen. No stigmatic spines. 
Male puparium with a large oval or circular operculum above the posterior 
extremity. 
The type species (gwevcus) was described by Comstock from Arizona 
(U.S.A.). Under the name of So/enxofhora, other species were recorded from 
New Zealand, by Maskell. Owing to preoccupation, this name was altered by 
Cockerell to Solenococcus. The genus Axtzecerococcus was founded by the 
author upon immature material received from Australia. The synonym Cerco- 
coccus, given by Scott to a species from Algeria, is the result of a similar 
misconception. The genus is represented in India.
