126 REPORT UPON A COLLECTION OF 



Previous records. From Canada, eastern United States, Mexico, and 

 the West Indies, on various hosts. 



Lower California records. From guava at La Paz. 



Notes: In all respects this species is so very similar to A. rapax Comst., 

 that the two may very easily be confused, the general characters of the pygidium 

 being practically identical. My specimens present a considerable amount of varia- 

 tion in the number and size of the plates (Figs. 47 A, B) but they appear con- 

 stantly to differ from rapax (Fig. 47 C) in the more or less deeply notched sec- 

 ond lobe and the much finer branching of the plates. 



As an additional host and locality, I may add Liriodendron tulipiferae in 

 New Jersey, (col. Doane) and "shade tree" at Raleigh, North Carolina, (from 

 collection of R. S. Woglum). 



Aspidiotus densiflorae Bremner. 



1920. Asipidiotus densiflorae Bremner, Ferris: "Scale Insects of the Santa Cruz 

 Peninsula," Stanford University Publications, Biological Sciences, 1 :1 :50, 

 fig. 27. 



Previous records. From Pasania densiflorae ("tan oak") and Quer- 

 cus chrysolepis in California. 



Lower California records. From an herbarium specimen of Quer- 

 cus tomentella from Guadeloupe Island, an island about two hundred 

 miles off the Pacific coast of the peninsula. 



Aspidiotus lataniae Sign. 

 1899. Aspidiotus lalaniae Sign., Green: Ent. Mon. Mag., 35:181. 



Previous records. A widely distributed tropical, subtropical, and 

 greenhouse species. 



Lower California records. From Forchammeria watsoni ("palo de 

 San Juan") at La Paz; Karwinskia humboldtiana between Cabo San Lu- 

 cas and Pescadero ; mango at San Bartolo. 



Notes : As there has been much confusion concerning the proper applica- 

 tion of the name lataniae I may point out that I am using the name for the 

 species described by Green in the reference cited above. This appears to be 

 the species that has ordinarily passed under the name of A. cydoniae Comst. 



Aspidiotus osborni Ckll. and Newell. 



1920. Aspidiotus osborni Ckll., Ferris : "Scale Insects of the Santa Cruz Penin- 

 sula," Stanford University Publications, Biological Sciences, 1 :1 :51, fig. 29. 



Previous records. Widely distributed on various species of oak in 

 the United States. 



Lower California records. From Quercus brandegeei near Santiago. 



Notes : I have but a single specimen from Lower California, this agreeing 

 quite closely with typical osborni except in having the plates somewhat larger.
