voL. iv.] A Mew Subspecies of Ceroplastes. 105 
by transmitted light, with many scattered black (as they appear) 
gland-dots. 
Adult 2, placed in caustic soda, appears crimson, and stains 
the liquid. 
The legs are very small, red-brown. ‘Tibia about one quarter 
longer than tarsus. Femur about one-third longer than tibia. 
Tarsal knobbed hairs well-developed. ‘The claw appears as if 
bulbous at the tip, but this is certainly due to the large bulbous 
- digitules, as in pszdzz. ‘ 
Compared with the figure of C. psidiz given by Signoret, the 
_ present subspecies seems very different; but when we come to 
compare the characters in detail, it is apparent that the differ- 
ences are those of degree rather than of kind, so that it is hard 
to accord to the Mexican form more than subspecific rank. 
C. psidit was found at Rio Janeiro, and is probably not to be 
separated as a species from C. janetrensis, Gray, 1828. 
The present insect belongs to a group of Ceroplastes which is 
characteristic of the neotropical region, and includes the follow- 
ing species: C. jamaicensis, White (Jamaica); C. cirripediformtis, 
Comst. (Jamaica, Florida); C. denudatus, Ckll., n. sp. (Antigua); 
C. depressus, Ckll., n. sp. (Jamaica); C. janezrensis, Gray (Brazil); 
C. plumbaginis, Ckll., n. sp. (Antigua); C. psidiz, Chav. (Brazil); 
and perhaps C. chilensis, Gray. The three new species mentioned 
will be described elsewhere.
