tles on the inner side of tarsus, and one at distal end of tibia. 
Tibia shorter than tarsus, but not so much so as in the adult, 
thus reversing the usual order of events. 
In C. tomentosus I noted, legs of larva with long claws, and 
longer tarsal hairs, tibia shorter than tarsus. In Jamaican C. 
cacti, second stage, I noticed the length of the claws. 
ostral Filaments.—In the very young larve of C. confusus 
and C. tomentosus, the rostral filaments are coiled like the 
spring of a watch, and very conspicuous. 
Anogenital Ring—The absence of hairs on the anogenital 
ring is given as a generic character of Coccus ; but these hairs, 
about six in number, were plainly seen in the second stage of 
Jamaican C. catci. 
Spines.—A]l three species have in the larva distinct rows of 
spines, which run longitudinally down the back, just as Sig- 
noret figures for Capulinia sallei. In C. tomentosus I found two 
parallel dorsal rows, and two rows on each side of the anterior 
part of the body, joining to form one row on the posterior 
half. These spines have sharp points, differently from the 
truncate processes of the adult. 
Male Sac.—In C. tomentosus, this is white, elongated, about 14 
mm.long. In Jamaican C. cacti it is quite similar. 
Adult Male. 
Size.—In C. tomentosus the body is about 1 mm. long. 
Color.—The male of C. cacti is said to be red-yellow (Sig- 
noret) or deep red (Ency. Brit., 9th Ed.). A male of Jamaican 
C. cacti, after being boiled in soda, showed the thorax and 
genitalia pale brownish, the abdomen pink. In a male not so 
. treated, the wings were observed to be white, appearing gran- 
ulose, about half their length extending beyond the body. 
In a living male of C. tomentosus, the body was dark purple- 
red, the wings whitish subhyaline, the veins not colored. 
Crushed under a cover-glass, the body gave a brilliant magenta 
color. " 
Caudal Filaments.—The abdomen of C. cacti from Jamaica 
emits two very long filaments. C. tomentosus also shows a 
pair of long white filaments.
