DISCUSSION OF GENERA AND SPECIES 



47 



Dinaspis kelloggi (Coleman). 



Fig. 23. 



A native species, originally described from this area, where it occurs 

 rather commonly on the Douglas Spruce, Pseudotsuga taxtfolia and oc- 

 casionally on pine. 



Fig. 23. Dinaspis kelloggi (Coleman) : pygidium of specimen from Pseudotsuga 

 taxtfolia on the Santa Cruz Peninsula. 



The original description of the species is quite accurate, but the figure 

 of the pygidium leaves much to be desired and I present a new figure. 

 The species is certainly not a Leucaspis. 



Genus LEPIDOSAPHES Shimer. 5 



Lepidosaphes newsteadi (Sulc). 

 Recorded by Coleman from Sciadopitys, near Stanford University. 



Lepidosaphes ulmi (Linn.). 



A common species on willow and apple. I have also taken it from 

 passion flower and from a native host, Xylothermia (or Picfteringia) 

 montana. 



5 It is probable that L. ceanothi Ferris occurs in this area, as scales almost 

 certainly of this species have been seen upon Ceanothus. However, no specimens 

 are available and the record can not be definitely established.
