The specimens belong to a dark and very convex variety, which also occurs in 
Southern Arizona.

This is a very uncertain species, never properly described. It is said to be 4 to 5 
millim. long, 3 millim. broad, reddish-brown, covered with a white waxy pellicle: 
antenne 7-segmented. Quite possibly it is Ceroplastodes niveus.

Hab. Mexico: Montezuma in Chihuahua (Cockerell); Mixcoac, on Mimosa, 1897

This may have to be called Ceroplastodes dugesi (Sign. & Licht.).

SCHIZOCHLAMIDIA, CkIL, gen. nov. 
Type S. mexicana. A Lecaniine Coccid, lacking legs and antenne in the adult; covered by a glassy scale 
which is divided into two parts longitudinally, and has not the rows of air-cells of Inglisia. The scale 
differs from that of Platinglisia in being convex, and not having the peculiar dorsal groove. It is just 
like Fairmairia externally, but lacks legs and antenne. It may be remarked that the name Fairmairia, 
Signoret, 1874, is a homonym of Fairmairia, Desv. 1863. The latter name, however, appears to be 
obsolete. It was at first intended to call this genus Schizochlamys, but that name belongs to a genus 
of Algsw. It may be considered permissible to use the same generic name in zoology and botany, but 
it certainly is not desirable. 
1. Schizochlamidia mexicana, Ckll. & Parrott, sp. n. 
9. Dark brown, with large ochreous spots, shiny, about 23 millim. long and rather over 2 broad, Lecantum- 
like, moderately convex, covered by a semitransparent white glassy scale, which consists of two portions,
