very decided change in the color of the wax, presumably due to 

 its drying out after death or separation of the insect from the 

 living host plant, and any differences in the color of the wax of 

 C. bergi, as compared with C. grand-is such as are noted by Cock- 

 erell, are easily susceptible of explanation as being due to the 

 stage of the drying-out process which had been reached when 

 they were described by Prof. Cockerell. 



Ceroplastes novaesi Hempel. 



The writer has identified as this species four lots of material, 

 two each from widely separated localities in Argentina, although 

 with some doubt and certain reservations. However, it is not 

 considered advisable, in view of the present condition of the 

 classification of this genus, to describe any new species where 

 material is possibly referable to any described species. The 

 specimens from the Jorgensen collection have been compared 

 with cotype material in the U. S. National Collection of Coccidae, 

 kindly contributed by Mr. Hempel. No material of Ceroplastes 

 novaesi mendozae Ckll. (Can. Ent. XXXIV, 1902, p. 93) has 

 been available for examination. The collections are as follows: 

 Mendoza, Argentina, on Baccharis salicifolia, Feb. 10, 1909, 

 collection number 14t; Mendoza, Argentina, on Baccharis subulata, 

 Feb. 8, 1909, collection number ISc; Bomplana, Misiones, Argen- 

 tina, on Baccharis sp. July, 1910, collection number 181a; Bom- 

 plana, Misiones, Argentina, on Compositae, June 1910, collection 

 number 72lh. 



Ceroplastes subrotundus Leon. 



The material at hand, as in the preceding species is somewhat 

 doubtfully referred to this species of Leonardi. The description 

 agrees quite well, particularly if allowances are made for the 

 scarcity of the material available to Leonardi for examination, 

 and for the rather poor condition of the Jorgensen specimens of the 

 species. It is represented by a lot of material from Cordillera 

 de Mendoza, Argentina, on Caesalpinia praecox (Leguminosae), 

 Feb. 8, 1909, collection number 4a. 



Ceroplastes lucidus Hempel. 



This species is represented in the Jorgensen collection b\ a 

 single lot of material from Mendoza, Argentina on Lippia 

 lycioides, Feb. 8, 1909, under collection number 1266. A com- 

 parison with cotypes of this species deposited in the U. S. National 

 Collection of Coccidae by Mr. Hempel shows no apparent mor- 

 phological differences and only the single external difference 

 that the color of the wax in the specimens from Mendoza is a 

 yellow-brown while in the type material it is strongly reddish 

 brown. Hempel in his original description notes this variation 

 in his material. It seems rather surprising to find this species
