Article XITI.— DESCRIPTIONS AND RECORDS OF COCCID. 
By T. D. A. CockERELL anp EizaBeTH RoBINSON. 
The material for the Philippine Islands, now reported-on, taken together 
with the specimens previously received, permits us to indicate briefly the 
general character of the Coccid fauna of the islands. 
(1.) Cultivated plants, at least in the Island of Luzon, are infested by 
many species, which are, with few exceptions, those common in tropical 
countries on the same or similar plants. 
(2.) This Coccid fauna of widely distributed species has undoubtedly 
been introduced by man. 
(3.) The truly indigenous Coccid fauna, found principally on native 
plants, consists mainly, perhaps wholly or almost wholly, of precinctive or 
endemic species, which are nevertheless allied to those of other tropical 
Asiatic countries. 
(4.) The number of endemic genera appears to be very small, and it 
may be that when the species of the various Malay islands are well known, 
it will appear that there are no genera peculiar to the Philippines. 
(5.) The above statement must in part be considered provisional, as 
we know little or nothing of the species occurring in remote, uncultivated 
parts of the islands. 
DIASPINZ. 
Schizaspis n. gen. (Diaspine.) 
Female scale small, circular or almost, flattened, with large exuvie much like 
those of Xanthophthalma, the first and second skins not separable. Male scale 
elongate but not parallel sided, white with terminal yellow exuvia, not keeled. Adult 
female with margins deeply incised, lobed between the incisions; no circumgenital 
glands; anal orifice large, near hind end; lobes and squames well developed. Imma- 
ture female oval, not lobed at sides. 
Schizaspis lobata new species. 
Female scale about .75 mm. diameter, flat, nearly circular, yellowish brown, the 
surface beaded with little prominences in concentric rows; exuvie large, sublateral or 
central, dull golden yellow, broad pyriform. 
Adult female yellow when boiled in liquor potasse, diameter about .5 mm., 
circular, with seven deep constrictions, the margin between them convex; one con- 
striction or incision is anterior, in the middle line, there is one on each lateral :
