COCCIDAE FROM LOWER CALIFORNIA 89 



short, stout spines and a rather slender curved spine about four times' as 

 long. Marginal spines quite numerous, arranged in an irregularly single 

 or double series, of various shapes and sizes. Some (Fig. 12D) are quite 

 short and stout, flattened and frayed at the tip, others are longer, more 

 slender and little or not at all frayed, and between these extremes are 

 various intermediate forms. Anal plates (Fig. 12C) of normal form, 

 each with three slender dorsal apical setae and three very long ventral 

 subapical setae and with two pairs of fringe setae, the outer long and 

 slender, reaching to the apex of the plates, the inner pair much shorter. 

 Antennae (Fig. 12A) 8-segmented. Legs with the tarsus (Fig. 12B) 

 broadly joined at the tibia. 



Notes : This species most closely resembles P. psidii Maskell but in the 

 latter species the marginal spines are practically all of the same length and are 

 broadly flattened and much frayed at the tip. 



Genus LICHTENSIA Sign. 



Lichtensia lycii Ckll. 



1919. Lichtensia lycii Ckll., Ferris : "Contribution to the Knowledge of the 

 Coccidae of Southwestern United States," Stanford University Publica- 

 tions, p. 38, fig. 17. 



Previous records. From Lycium in New Mexico. 

 Lower California records. From Solanum sp. near La Rivera and 

 at Todos Santos and from Lycium sp. at San Jose del Cabo. 



Notes : These specimens differ from New Mexican examples in their some- 

 what smaller size and in lacking the glazed appearance of the ovisac; .structurally 

 they appear to be identical. 



Genus CEROPLASTES Gray. 



Ceroplastes cirripediformis Comst. 



Previous records. From southern United States, Mexico and West 

 Indies, on various hosts. 



Lower California records. From undetermined ornamental vine at 

 La Paz. 



Notes: I have not seen authentic specimens of cirripediformis but these 

 examples agree quite closely with the various descriptions and figures of that 

 species. 



Ceroplastes irregularis Ckll. 



Previous records. From various species of Atriplex throughout 

 southwestern United States. 



Lower California records. From Atriplex sp. at La Paz. 



Notes: These specimens agree structurally with typical examples of the 

 species but have the secretionary covering very thin and dark brown with black 

 apical markings.
