SCALE INSECTS OF SANTA CRUZ PENINSULA 



Genus TARGIONIA Sign. 



The type of this genus is a somewhat Chrysomphaloid form with 

 which probably few of the North American species now referred to this 

 genus are strictly congeneric. I consider that the one species coming 

 within the scope of this paper, T. dearnessi Ckll. and Par., should prob- 

 ably be referred elsewhere and that a new genus will eventually be 

 necessary for this and certain other closely allied species. I would espe- 

 cially call attention to the nature of the ducts in all these species. 



Targionia (?) dearnessi Ckll. 



Fig. 34. 



From Grindelia cuneifolia.'m the salt marshes about San Francisco 

 Bay and from Eriophyllum confertiflorum in Stevens Creek Canyon. This 

 species is also abundant on Corethrogyne sp. at Cypress Point near Pacific 

 Grove.

 type material. 



The accompanying figure will supplement the original description, 

 and I may note that there are numerous ducts along the lateral margins 

 of the abdomen. All the ducts are very small and short and appear to 

 be of the type indicated in Fig. 345. The determination of the species is 

 based upon the examination of specimens from the type material.
