pygidial margin. Spines strong, prominent; a single spine laterad of 

 each of the lobes, two laterad of each of the second and third incisions 

 and two about midway of the pygidial margin. Anal opening slightly 

 caudad of the knobs of the chitinous processes of the second incisions, 

 about two-thirds as large as a single knob. Genital opening about nine 

 times the length of the lobes above them. Three rows of dorsal pores 

 of from seven to nine pores each, extending up into the pygidium at an 

 acute angle to the pygidial margin. 



Note.—lt was the original intention of the writer to describe 

 this as a new species; indeed, this was done in manuscript form 

 as it appears above. In December, 1916, Dr. Marlatt kindly 

 granted him access to the Coccid collection of the Bureau of 

 Entomology, and during this study it developed that an iden- 

 tical species was known under the manuscript name of A. 

 subsimilis var. anonce in the Bureau's collection. Upon learning 

 of the writer's material. Dr. Marlatt generously insisted that 

 their material be included with his and published. The collec- 

 tion records of the Bureau's material were: 



.1. On Anone sp. Lima, Peru, 1909, E. R. Sasscer. 



2. On Mangifera acambodiana, , Miami, Fla., 1910, E. R. 



vSasscer. 



3. On Loquat, Miami, Fla., 1910, E. R. Sasscer. 



The following are Dr. Marlatt's manuscript notes: 

 "Aspidiotiis subsimilis Ckll. Is very closely allied to 

 courseticB sp. nov., the latter perhaps not deserving more than 

 varietal rank. It is readily distinguished from the ancylus 

 group of species, to which it is closely allied, by the elongated 

 and knobbed character of the inner chitinous thickening or 

 paraphysis of the first incision, resembling in this respect 

 somewhat Aspidiotiis idmi Johnson. 



"Some material showing a slight divergence from the type 

 was collected in the Department greenhouses by Mr. Sasscer 

 on Anona sp. imported from Lima, Peru. This form is more 

 chitinized than the type material of subsimilis, the knobbed 

 paraphyses are a little longer, and the anal orifice a little more 

 remote from tip. When a larger acquaintance with subsimilis 

 is gained by future collections and study, this variety will very 

 probably be found to fall within the variation of the species. 

 For the present, however, it may be designated as subsimilis 

 var. anonce.'"
