COCCIN AL. 
PSEUDOCOCCUS, Westwood. 
Coccus, L., was first subdivided by Geoffroy, who uses Chermes (not Chermes, Linn., 
which is the proper name for Psyl/a) for Lecanium, &c., and restricts Coccus to those 
species which in the females “ retain the shape of an insect.” Geoffroy has three species 
under Coccus, and only one of these, C. phalaridis, is mentioned in the tenth edition 
of the ‘Systema Nature.’ This must apparently be regarded as the type of Coccus ; 
it seems to be a Ripersia. See Proc. Acad. Nat. Sci. Phil. 1899, p. 260. 
1. Pseudococcus cacti. 
Coccus cacti, Burm. Handb. der Ent. ii. p. 72 (1839) (nec Linn.). 
Hab. Mextco; Guatemata; Honpuras; Satvapor; NIcARAGUA. 
For a discussion of its detailed distribution, see Edward Wiepen, JB. d. Hohere 
Biirgerschule de Stadt Koln, 1889. Burmeister’s type was from Mexico. 
The insect described as Coccus cacti by Linneus, Syst. Nat. ed. x. p. 497, which he 
received from Daniel Rolander, is a Monophlebid, as can readily be seen by consulting 
DeGeer’s figures of specimens from the same source. ‘The Linnean description is full 
enough to show that his insect was not the cochineal. Burmeister’s description, and 
also his references, pertain to the true cochineal. 
2. Pseudococcus tomentosus. 
Coccus tomentosus, Lam. (opuntie, Licht. MS., Ckll.); Ck. Bull. 4, Techn. Ser., Div. Ent., U.S. 
Dept. Agric. (1896) p. 35. 
Hab. Mexico: Guanajuato and Silao (Dugés). Var. newsteadt, Ckll.: La Puerta 
Rancho in Tamaulipas (Townsend).
