COCCIDAE FROM LOWER CALIFORNIA 



81 



Penultimate stage similar to the adult except that the anal lobes are 

 much less prominent, the tubular ducts fewer and the abdomen bears a 

 row of moderately large spines along the margin. 



Fig. 8. Xerococcus fonquieriae n. sp. : A, adu.lt female; B, spiracle; C, type of 

 pore; D, anal ring; E, antenna of adult female; F, type of duct; G, an- 

 tenna of first stage; H, first stage. 



First stage (Fig. 8H) with 6-segmented antennae (Fig. 7G). Mar- 

 gins of the body, especially along the posterior portion of the abdomen, 

 beset with a single row of short, stout spines. Anal lobes very low, each 

 with a single slender seta. Anal ring very small, apparently as in the adult. 



Notes : The host of this species is restricted to Lower California, but one 

 other species of the same genus, Fouquieria splendens, is abundant throughout 

 southwestern United States and northwestern Mexico and it is probable that this 

 Coccid will eventually be found to occur upon it. 



Genus KERMES Boitard. 

 Kermes sp. 



Host and locality. From Quercus idonea on Mt. San Bernardo. 



Notes : But a few specimens of this species were taken. Owing to the 

 fact that determinations in this genus are scarcely possible in the existing con- 

 dition of the literature and to a belief that new species should be described in 

 the genus only when the younger stages are available I refrain from describing 

 this species.
