One species I am referring doubtfully to Eriococcus palmeri Ckll., a 

 species heretofore recorded only from Carmen Island in the Gulf of 

 California. 



Twenty-nine species are here described as new. It is not impossible 

 that some of these will eventually prove to be identical with species 

 already described from Mexico. Some are very closely related to northern 

 forms, being perhaps in the nature of subspecies as that term is under- 

 stood by mammalogists and ornithologists, and others will almost certainly 

 be found to occur in the United States and northern Mexico. A few may 

 prove to be truly autochthonous in the peninsula. The list of new species 

 is as follows> 



Steatococcus tabernicolus. 

 Orthezia caudata. 

 Asterolecanium cristatum. 

 Fonscolombia peninsularis. 

 Eriococcus tillandsiae. 

 Eriococcus paucispinus. 

 Xerococcus fouquieriae.
