VOL. IV,] A New Sttbspecies of Ceroplastes. 105 



by transmitted light, with many scattered black (as they appear) 

 gland-dots. 



Adult $ , 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 psidii. 



Compared with the figure of C. psidii given by Signoret, the 

 present subspecies seems very diflFerent; 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. psidii was found at Rio Janeiro, and is probably not to be 

 separated as a species from C. janeirensis^ Gray, 1828. 



The present insect belongs to a group of Ceroplastes which is 

 characteristic of the neotropical region, and includes the follow- 

 ing species: 6". y<T:;«^zVi?«5/^, White (Jamaica); C a'rripediformis, 

 Comst. (Jamaica, Florida); C demcdatus, Ckll., n. sp. (Antigua); 

 C. depresses, Ckll., n. sp. (Jamaica); C. Janeirensis, Gray (Brazil); 

 C. pliimbaginis, Ckll., n. sp. (Antigua); C. psidii, Chav. (Brazil); 

 and perhaps C. chile?isis, Gray. The three new species mentioned 

 will be described elsewhere.
