XANTHOPHTHALMA.—PROTODIASPIS, 33 
XANTHOPHTHALMA, Ckll. & Parrott, gen. nov. 
Type X. concinnum. A genus of Diaspine having a peculiar scale, as described below under the species ; and 
the abdominal margin ending in rounded processes, at the ends of which are small bristles. No squames, 
No circumgenital glands. Allied, apparently, to Protodiaspis. The female scales resemble the male 
scales of other Diaspine, at least in general appearance. The first skin retains the larval antenne as 
in Diaspis. . 
1. Xanthophthalma concinnum, Ckll. & Parrott, sp. n. 
Q. Scale very minute, hardly half a millim. long, white, with the first skin bright orange and placed longi- 
tudinally. The first skin is large for the size of the scale, eye-shaped, with a longitudinal bright orange 
ridge, and the depressed areas on each side of this blackish, the whole looking like a lizard’s eye, closed. 
The second skin is placed beneath the first and is inconspicuous. The scale is convex and presents 
a succession of transverse crests or ridges, so that it seems as if made of a number of discs threaded 
together. The scale has much the general shape of a Pulvinaria ovisac, with the first skin taking the 
place of the female Pulvinaria. 
Q. After boiling in caustic soda, nearly circular, transparent; the end of the abdomen minutely serrulate, and 
ending in six approximately equal rounded processes, on the end of each of which is a small bristle. 
Anal orifice circular, near the hinder end. Embryo:in female very large.

d. On the leaf, usually in little pits, were some small white Diaspis-like male scales, with the exuvia at one 
end, and black. The colour of the exuvia makes us doubt whether they really belonged to Xanthophthalma. 
Hab. Mexico: Coatzocoalcos in Vera Cruz, April 24, 1898, on leaves of a large tree 
called “laurel” (Townsend). 
Scales on under surface of leaf, scattered all over in numbers, but not massed, being 
distributed at rather regular intervals, though five or six are often bunched together.
