356 R. Newstead: Coceidae and Aleurodidae of Madagascar and Comoro Is. 
Puparium of second stage female (fig. 2) black, shining, more or less circular, clothed with 
numerous long spiniform hairs, with the central spiny boss and fringe as in the adult. 
Ovum (fig. 3) yellow, pedunculate, curved, swollem basally, bluntly pointed, anteriorly; euticle ' 
finely punctate. After the escape of the larva (fig. 3) it bears a marked resemblance to a univalve shell. 
Habitat: Ste. Marie (Madagascar), August 1904. 
On an unnamed plant the leaves of which were almost completely covered with the black puparia, 
larvae, and eggs. Although so numerous, I failed to find a puparium which had not been ruptured by the 
escape of the imago. The boss-like process on the dorsum of the puparium is very remarkable, it serves | 
at once to distinguish the species. In most instances it appears to be semi-detached, so that in all 
probability it represents the larval exuviae, though I cannot find that any previous author has discovered | 
a similar trait in this family of the Homoptera. The tests of the younger individuals (fig. 2) are still 
more remarkable in that they appear like little, black, spiny pillars, resembling in form some of the 
- succulent echinocacti. 
The species is dedicated in honour of its discoverer Dr. Voeltzkow.
