" Foem. In fovea verruciformi Crustacea arete inclusa, paramorphosi inflata, 

 apice incisa, squamisque caudalibus minimis pradita, acera, apoda. 



" Labio postico articulato dimero ; Chorio fusis geminatis tubularibus sparse." 



The female is thus described, and it and the larva are also 

 figured : — 



" Foem. In fovea Crustacea crassiuscula, similibus congregata, ramisque simul 

 adhserentibus, arete clausa, globularis elliptica, crocea, IsBvi, nitens, postice bidentata. 



" Os, rostro rhomboideo, labio cordiformi elongato dimero ; squamis analibus 

 triangularibus obtusis adpreseis, apice spinulosis, minimis. 



" Chorio densiusculo, nitido, fusis geminatis, crebris, subregulariter disseminatis. 



" Mas adhue ignotus." 



Of the spinnerets on the body of the adult insect nothing is 

 said, but of those on the larva it is stated: — 



" Delle grandi filiere, delle quali sembra doppio il lume, vedendosi I'orificio su- 

 perficiale e profundo quasi in uno stesso piano, formano due serie parallele all 'asse 

 del corpo di sopra, e per ogni lato." 



Tet on the figure of the upper-side of the larva, besides the two 

 dorsal row^s of double spinnerets, only one row of them appears on 

 each side, 



Signoret, adopting the genus and describing the same species 

 (Ess. Cochen., p. 162), says that "the larva in its lecanoid form has 

 neither feet nor antennae, only vestiges of the latter as a triangular 

 tubercle with some hairs, fig. Id" But at p. 472 he says that " fig. 1^" 

 represents the atrophied antenna of the adult ; the term " larva," 

 therefore, is an error, in view of the fact that in his description and 

 figure of the larva it is represented as having both the antennae and 

 the legs. 



The character of double and single spinnerets on the integument 

 is given the same as by Targ.-Tozzetti, and it is added that " the em- 

 bryonic female has four series of tubes, each with a double opening — 

 two on the median part and two on the lateral margins." Interpreted 

 by the fig. " Id " this means two rows on the dorsum and one on each 

 lateral margin, making up the number four. The spinnerets on the 

 lateral margins of the body of the adult are not mentioned, but they 

 have been understood to be as in the larva, and to give rise to only one 

 row of fringe, for Maskell, in his "Account of the Insects of New 

 Zealand," p. 87, says of the genus PoUinia, " Test hard, waxy, with a 

 single fringe." Signoret also says of the adult female form that " the 

 anal extremity has a very small opening with two very small lobes 

 scarcely visible ; the anal ring with eight hairs ;" also that the mentum 

 is biarticulate, and otherwise his description agrees with that of 

 T. Tozzetti.
